How to Improve Indoor Air Quality - Fight Common Sources of Indoor Air Pollution

Although it's great to get outside on nice spring, summer and fall days, Americans typically spend about 90% of their time indoors where the concentration of contaminants and pollutants are two to five times greater than the air outside. When you're cooped up inside, natural airflow is limited. For this reason, it's important to ensure that the air quality in your Indianapolis home is at a high level, especially for those who suffer from allergies, asthma or other respiratory illnesses. Even with your HVAC system running, you are still going to be exposed to much of the same air throughout the day. What this means is that anything inside your home that compromises air quality is going to stay inside and circulate. Poor air quality can cause illness, trigger allergies and asthma or just make it harder to breathe. To help keep you and your family healthy year-round, here are a few tips for keeping your indoor air quality fresh and clean.

Identify Common Indoor Air Pollutants and Pollution Sources

What Pollutants Are Found in Indoor Air?

To improve indoor air quality in your Indianapolis home, it’s important to understand the most common indoor air pollutants and where they come from. Many homes across Central Indiana experience indoor air quality issues caused by everyday activities, materials, and limited airflow. These pollutants can build up quickly, especially when outdoor air circulation is low during hot summers or cold winters.

Common indoor air pollutants include dust, pet dander, mold spores, bacteria, and microscopic particles that settle into carpets, floors, and furniture. Pet dander and allergens are especially problematic for households with pets or residents who suffer from allergies, as these particles continuously circulate through the air. In addition, volatile organic compounds (VOC) released from cleaning products, paints, and household materials contribute to indoor pollution and can negatively impact your health over time.

Poor ventilation allows these pollutants to linger, reducing overall indoor air quality. Opening windows when weather permits can help bring in outdoor air and dilute indoor pollution, but this must be balanced carefully during high pollen seasons in Indianapolis. Simple steps like keeping floors clean, regularly vacuuming, and using a damp mop can help reduce the buildup of particles that affect your indoor air.

Moisture is another major factor that impacts indoor air quality. If you do not control moisture or keep humidity levels in check, mold and mildew can develop, releasing additional air pollutants into your home. Using humidity sensors or whole-home solutions can help keep humidity levels balanced year-round and protect your indoor air quality.

To improve indoor air and create a healthier living environment, it’s important to eliminate individual sources of pollution whenever possible and reduce their emissions. This may include switching to low-VOC cleaning products, using an air purifier, upgrading air filters, and even incorporating indoor plants to support cleaner air. Air monitors can also provide insight into your indoor air quality levels, helping you make informed decisions about your home’s environment.

At Chapman Heating, Air Conditioning, Plumbing & Electrical, we help homeowners throughout Indianapolis identify and address indoor air quality concerns with customized IAQ solutions. From filtration upgrades to advanced purification systems, improving indoor air quality starts with understanding what’s in your air and taking the right steps to remove it.

Be Careful with VOC Cleaning Products

VOC (volatile organic compounds) are solid or liquid cleaning products that emit potent chemicals when used. As you can probably guess, chlorine bleach, furniture polish, aerosol sprays, oven cleaners and rug cleaners are all very common household VOCs. When these kinds of cleaners are used without precaution, the chemicals can linger in the air and can cause headaches, dizziness, nausea and more. Whenever possible, use VOCs outside to keep them out of your indoor air circulation. If you must use them indoors, make sure you are in a ventilated area, like your bathroom or kitchen, and can push the chemically tainted air outdoors.

Increase Ventilation to Reduce Stale Indoor Air

Open Windows When Weather Permits

When the weather is nice, turn off your air conditioner or furnace and let in some fresh air. Open windows can help with circulating fresh air throughout your home. Giving your HVAC a little rest can also help with your energy bill. Just be careful if you suffer from pollen allergies. While this allows for clean air to enter, it also opens the door for pollen and other outdoor allergies to enter, so act accordingly.

Keep a Healthy Humidity

During the warmer months, dust mites and mold thrive in high humidity levels. If left unchecked, these pollutants and contaminants can take hold and taint your indoor breathing air. Dust mites, mold and mildew are extremely common allergies and can trigger allergy and asthma symptoms. You may not think about humidity during the fall and winter months, but it is just as important. Low humidity levels create dry air, which helps with the spread of viruses such as the cold and flu. Maintaining a humidity level of 30 to 50% year-round will keep humidity levels in check. Utilizing a dehumidifier in your home during the summer and a whole house humidifier during the winter will keep your humidity levels at a comfortable level.

Regularly Clean, Vacuum, Mop and Dust

Maintaining a clean home is important in keeping air quality high. Dust, dirt, pet dander and other particles can build up and easily be kicked up from regular home activities. Although dirt, dust and dander aren't dangerous, they can make breathing difficult and result in coughing and sneezing as well as triggering other allergy and asthma symptoms. Vacuum carpets and furniture, use cleaning supplies without harmful chemicals and dust and mop on a regular schedule to prevent build up.

Install an Air Purifier and Upgrade Air Filters

Benefits of a Whole-Home Air Purifier System

For an extra level of protection, Chapman Heating, Air Conditioning, Plumbing & Electrical recommends installing a whole house air purifier or UV light air cleaner to your home's HVAC system. These systems integrate directly with your existing equipment to continuously treat the air as it circulates, rather than relying on portable units in a single room. Whole-home solutions are designed to capture and neutralize airborne pollutants such as pet dander, tobacco smoke, dust, and allergens so they do not re-enter your home's air supply. By improving overall air cleanliness, they can help reduce allergy symptoms, limit airborne irritants, and create a healthier indoor environment for your family.

How Air Filters Help Capture Pollutants

Your HVAC air filters play a critical role in trapping pollutants before they circulate throughout your home. As air moves through your system, filters capture dust, debris, and microscopic particles that can impact indoor air quality. It’s important to change your HVAC filter regularly, typically about every three months, but homes with pets, allergies, or higher usage may require more frequent replacement. Choosing the right filter type and rating can also improve performance and efficiency. To learn more about selecting the right hvac filtration system, consider consulting with a professional to ensure your system is properly equipped to handle your home's air quality needs. Always refer to your owner's manual for the correct replacement schedule and specifications.

Your home's air conditioner holds significant importance among its appliances. A malfunctioning unit can cause considerable inconvenience for homeowners. AC capacitors play a crucial role in the functioning of any Indianapolis HVAC air conditioning system, and a deteriorating capacitor can precipitate AC problems.  Before running down the rabbit hole of replacing your air conditioner, check this important AC component.

What Is an Air Conditioning Capacitor?

An AC capacitor is a piece of equipment inside the outdoor condensing unit of an air conditioner. The AC capacitor delivers power to the motor driving the air conditioning system. The capacitor jumpstarts the cooling cycle by providing a surge of energy to the system. It then sustains operation by supplying consistent electricity until the cycle finishes. Initially, it delivers a power surge equivalent to 300 to 500 percent of the system's normal electrical requirement.

Once the air conditioner motor reaches its optimal speed, the capacitor regulates excess power and provides a stable energy supply throughout the cooling process. Much like a battery, the AC capacitor is similar to a battery, storing and distributing energy as needed during operation.

How Long Does an Air Conditioning Capacitor Last?

No homeowner wants to deal with ac issues, especially during the summer months. With the AC capacitor being the air conditioning unit’s main component, a fully functioning AC capacitor is a necessary item to avoid uncomfortable living conditions. AC capacitors can last a long time but will need to be replaced down the road.

With routine maintenance on your Indianapolis air conditioning unit, an AC capacitor can last up to 20 years. To avoid any issues, scheduling regular maintenance with a professional can make a world of difference. Following up on this advice will contribute to the longevity of your AC capacitor and your air conditioning unit as a whole.

7 Signs of a Bad AC Capacitor

Being able to tell the signs of a faulty AC capacitor is a key first step to diagnosing possible AC issues. Here are seven signs to tell if your AC capacitor is bad.

 1. Air Conditioner Blowing Warm Air

When your air conditioner is running but is failing to blow cold air throughout your home, it could be a faulty AC capacitor. This symptom is insinuated by the air conditioning unit blowing out warm air. When the AC capacitor is bad, it prevents itself from starting and the air conditioner is no longer able to remove heat and transfer it outside the home.

2. Humming Noise from the HVAC system

Another sign of a faulty AC capacitor is a humming noise coming from the access panel of the condenser unit. This will force the capacitor to operate at an excessive level, resulting in that mentioned humming noise.

This sound might also originate from the AC motor. To differentiate the noise, try turning the AC unit on and off. If the humming persists, it’s likely stemming from the AC capacitor.

3. Burning Smell from a Bad Capacitor

A particularly worrisome sign for a homeowner is a burning smell coming from the condenser unit. This smell usually signifies a faulty AC capacitor. This may be due to item obstruction, normal wear and tear for the system, or even overexertion. You might be able to fix it by lubricating the bearings, but replacement will be a better option for a long-term solution.

4. High Energy Bills

If your capacitor is damaged, it will cause the compressor to overwork itself. When components within the air conditioning system are run excessively, this can lead to higher energy bills. Identifying symptoms like high energy bills and getting repairs will prevent costs from compounding on top of each other. Having to pay higher energy bills and repairs is a nuisance that nobody wants to deal with.

5. Air Conditioner Turns Off

One of the many signs of a bad capacitor is the air conditioner turning off suddenly. The air conditioning system should never shut off on its own. It’s common for the unit to short circuit now and then, but continuous issues with your air conditioner need to be evaluated for a permanent fix.

6. Air Conditioner Won’t Turn On

Setting your thermostat to your desired temperature and the air conditioner refusing to turn on is an issue no homeowner wants to face. One of the issues that could cause this is a bad AC capacitor. If the AC capacitor is indeed bad, the air conditioner may take longer to turn on or won’t turn on at all. Severe damage to the AC capacitor may cause the air conditioner to not turn on period.

7. Aging HVAC System

The last sign your AC capacitor is faulty is the age of the component itself. If your air conditioning system is older and is struggling to maintain cooling cycles, this is a telltale sign that the AC capacitor has worn out over time. If the AC capacitor is bad, the system will not fulfill your home’s cooling demands, which leads to higher energy bills and a less comfortable home.

You're probably familiar with the phrase get some fresh air. You might tell your child to turn off the video games and go outside for some of that fresh Indiana air. But did you know the same idea applies to your home itself? A fresh air ventilation system helps bring clean air into your living space, without sacrificing the energy efficiency modern homes are built around.

What Are Fresh Air Ventilation Systems and How Do They Work?

Today's homes are built tight. That's intentional — better insulation and sealed construction help reduce heating and cooling loss and lower your monthly energy bills. But that same tightness has a downside: it restricts fresh air from naturally flowing into your home. The result is stale, allergen-filled indoor air that circulates over and over with nowhere to go. This can be especially true in Indiana, where homes are sealed up tight against brutal winter cold from November through March — and then closed back up again all summer for air conditioning. That means for the better part of the year, your home isn't getting the natural ventilation that milder, open-window seasons provide.

Dust, pollen, pet dander, and other pollutants become trapped inside, and without fresh air coming in to dilute them, your indoor air quality suffers. Fresh air ventilation systems solve this problem by continuously bringing in outdoor air while pushing stale indoor air out, all without the energy penalty of simply cracking a window.

So why not just open a window? Opening a window does bring in fresh air, but it also dumps the energy your system worked to heat or cool right outside. A fresh air ventilation system retains most of that energy through a controlled exchange process, making it far more efficient. It's also considerably safer than leaving windows open around the clock.

Ventilation Systems are different from:

Balanced Ventilation for Modern Homes

The goal of any whole-house ventilation strategy is balance.  This means equal amounts of fresh air coming in and stale air going out. Balanced ventilation systems achieve this by operating supply and exhaust fans simultaneously, maintaining consistent airflow throughout every room in the home.

The benefits go well beyond comfort:

Without mechanical ventilation, energy-efficient homes can actually trap more pollutants than older, leakier homes. Modern house ventilation systems are the answer to that trade-off.

Types of Fresh Air Ventilation Systems

Understanding your options is the first step toward choosing the right system. There are three primary categories of fresh air ventilation:

Exhaust Ventilation Systems

Exhaust ventilation works by depressurizing the home — fans push stale indoor air out, and fresh air is drawn in through small gaps and passive vents. These systems are simple and cost-effective, but they work best in colder climates and can sometimes draw in unconditioned or polluted air from unintended locations like crawl spaces or garages.

Supply Ventilation Systems

Supply ventilation does the opposite — it pressurizes the home by mechanically pushing fresh air in while stale air escapes through leaks and exhaust points. These systems give you more control over where fresh air enters and are better suited to hot or mixed climates. However, they can introduce humidity in warmer months if not properly managed.

Balanced Ventilation Systems: HRVs and ERVs

Balanced ventilation is the most complete solution for most homes, and it comes in two highly efficient forms: Heat Recovery Ventilators (HRVs) and Energy Recovery Ventilators (ERVs).

HRV (Heat Recovery Ventilator): A heat recovery ventilator transfers heat from outgoing stale air to incoming fresh air, so you're not losing the energy your furnace already worked to produce. This makes HRVs especially effective in colder climates where heating costs are the primary concern.

ERV (Energy Recovery Ventilator): An energy recovery ventilator goes a step further by transferring both heat and moisture. In humid climates or during summer months, an ERV helps keep incoming air from adding unwanted humidity to your home. In dry winter conditions, it helps retain indoor moisture for comfort.

Both types of ventilators connect to your existing HVAC system and operate quietly in the background — bringing in fresh air, exhausting stale air, and preserving the energy your system has already used.

Energy Recovery Ventilation and Energy Efficiency

One of the biggest hesitations homeowners have about fresh air ventilation is the impact on energy bills. It's a fair concern. Introducing outdoor air means your system has to condition it. That's where energy recovery ventilation systems earn their value.

ERVs and HRVs recover between 70% and 80% of the energy from exhausted air before it leaves your home. That means you're getting continuous fresh air exchange while keeping your heating and cooling loads — and your bills — under control. In fact, high-performance ventilation systems often pay for themselves over time through reduced strain on your HVAC equipment and lower energy consumption overall.

The key advantage of energy recovery systems over simply opening windows or relying on exhaust fans alone is that they treat ventilation as a two-way exchange, not a one-way loss.

Choosing the Right Ventilation System for Your Home

No single system is the best option for every household. The right choice depends on several factors:

Climate. HRVs are typically the better fit for cold climates where heating is the dominant energy cost. ERVs are often preferred in hot, humid climates where moisture control is just as important as temperature.

Home size and layout. Larger homes or those with complex floor plans may require zoned or whole-house ventilation approaches to ensure even air distribution throughout all living areas.

Existing HVAC systems. Most fresh air ventilation systems are designed to integrate with your current heating and cooling equipment, but compatibility and duct configuration should be confirmed by a professional before installation.

Indoor air quality needs. Households with allergy sufferers, asthma, or sensitivities to indoor pollutants may benefit most from high-efficiency ERV or HRV products paired with high-quality filtration.

At Chapman Heating and Air, we offer fresh air ventilation systems from trusted brands including Honeywell. Two standout options include:

Both systems operate quietly and require minimal maintenance, making them practical for busy households.

Installation and Maintenance of Ventilation Systems

Proper installation is everything when it comes to fresh air ventilation. An incorrectly installed system can create pressure imbalances, introduce unconditioned air in the wrong areas, or fail to deliver the energy efficiency gains it's designed for. Professional installation ensures that airflow is balanced, ductwork is properly connected, and the system is calibrated to your home's specific needs.

Ongoing maintenance is straightforward but important. Routine tasks typically include:

With proper care, fresh air ventilation systems are built to deliver reliable performance for many years.

At the risk of telling you something you're tired of hearing, replace the air filter in your furnace on a regular basis. Dirty air filters reduce the amount of air flowing through a system and make the furnace work harder to maintain the temperature. How often you change the filter depends on the type of filter you use, if you have pets, and the size of your equipment. Please give us a call and we can give you proper guidance.

Keeping your home comfortable and your energy bills manageable starts with one surprisingly simple habit — changing your air filter on schedule. Yet it's one of the most overlooked parts of home maintenance. If you've ever wondered how often should I change my air filter, you're in the right place.

How Often Should You Change Your Home Air Filter?

Quick answer: every 1–3 months for most homes.

That range exists because no two homes are exactly alike. A single-occupant home without pets may get away with changing filters every 90 days, while a busy household with dogs, cats, and allergy sufferers may need a fresh filter every 30 days.

Your HVAC system depends on clean air filters to do its job. When airflow is unobstructed, your system runs efficiently, your home reaches the set temperature faster, and the air you breathe stays cleaner.  Skipping regular filter changes puts all of that at risk and costs you more in the long run. When an air filter is clogged or dirty, your HVAC system will struggle to pull in air, you'll use more energy to reach the set temperature, and your indoor air quality is greatly reduced.

What Happens If You Don't Change Your Air Filter Regularly

Neglecting filter maintenance isn't just an oversight; it's an invitation for problems that compound over time.

Reduced airflow and uneven temperatures. A clogged air filter chokes off the airflow your HVAC system needs. Rooms that were once comfortable may feel stuffy or inconsistently heated and cooled, and your system has to work harder to compensate.  These leads to more air conditioner repairs and maintenance.

Higher energy bills and system strain. When your HVAC system is forced to pull air through a dirty, blocked filter, it runs longer and draws more power. That extra effort shows up directly on your energy bill and accelerates wear on components like the blower motor — potentially leading to costly heating system repairs.

Increased allergens and poor home air quality. HVAC filters are your home's first line of defense against dust, pollen, pet dander, and other airborne particles. A saturated filter stops capturing these contaminants, and may even start releasing them back into the air. For anyone with asthma or allergies, this can make symptoms noticeably worse.  While installing air purification systems can help, replacing a dirty filter is always the first plan of attack.

How to Tell When Your Air Filter Needs to Be Replaced

Not sure if it's time? Here are three clear signals to watch for:

  1. Visible dirt, dust, and discoloration. Pull the filter out and perform a visual inspection. If it looks gray, brown, or completely clogged with debris, it's past due for a swap. A new filter should appear light-colored and clean.
  2. More dust in your home or worsening allergy symptoms. If you're noticing dust settling on surfaces faster than usual, or household members are sneezing more, your filter may no longer be doing its job.
  3. Your HVAC system is running longer than usual. When it takes noticeably more time to heat or cool your home, a dirty filter is often the culprit. Your system is working overtime to start and maintain airflow through a restricted filter.

Factors That Affect How Often You Should Change Your Air Filter

Pets and Household Size

Pet hair and dander are among the biggest reasons filters clog faster. If you have one or more furry companions at home, plan to change your filter every 30–45 days. Larger households — more people, more activity — also generate more dust and debris, shortening how long a filter stays effective.

Home Air Quality and Allergies

Homes where residents have allergies, asthma, or respiratory sensitivities benefit from more frequent filter changes — often every 20–45 days. Keeping filters fresh is one of the most impactful ways to maintain better home air quality and reduce symptom triggers.

HVAC Usage and Seasonal Demand

Heavy use during summer cooling season and winter heating months puts significantly more wear on your HVAC filters than during mild shoulder seasons. If your system is running nearly around the clock, check your filters more frequently during these peak periods.

Filter Type and Thickness

Not all air filters are created equal. Thicker, higher-quality filters may capture more particles and last a bit longer, but they still need regular monitoring. Filter sizes and construction vary widely, so always check the manufacturer's recommendations alongside these general guidelines.

Recommended Schedule for Changing Your Home Furnace Filter

Household Type Recommended Change Interval
Vacation home / rarely occupied Every 6–12 months
Single occupant, no pets Every 90 days
Average family home Every 60 days
Home with one pet Every 30–60 days
Multiple pets or allergy sufferers Every 20–45 days

Different Types of Air Filters and Their Replacement Timeline

Standard Fiberglass Filters

These are the thinnest, most affordable option — typically 1 inch thick. They provide basic protection for your HVAC system but capture fewer fine particles. They generally need to be replaced every 30 days and offer minimal benefit for home air quality or allergy relief.

Pleated Filters

Pleated filters are the most commonly recommended option for residential use. Their accordion-style design creates more surface area to trap dust, pollen, pet dander, and mold spores. Most pleated filters perform well for 60–90 days depending on household conditions. These represent a solid balance of cost, quality, and convenience for most homeowners.

High-Efficiency Filters (HEPA and High-MERV)

High-efficiency HVAC filters are designed to capture very fine particles, making them ideal for homes with severe allergies or air quality concerns. They can last 6–12 months, but their dense construction can restrict airflow if your system isn't designed for them. Before upgrading to a high-MERV or HEPA filter, consult with a professional to confirm compatibility with your system.

When choosing the right air filter, consider your household needs, your system's specifications, and filter sizes that fit correctly. A filter that's the wrong size — even slightly — allows unfiltered air to bypass it entirely.

When to Call Chapman Heating and Air for Help with Your Air Filter

Changing your filter regularly handles the majority of routine maintenance, but some situations call for professional attention.

Persistent airflow issues even after replacing the filter. If rooms are still not heating or cooling properly after a fresh filter is installed, the problem likely goes deeper — possibly a duct issue, blower problem, or refrigerant concern.

Unusual noises or system inefficiency. Rattling, banging, or whistling sounds from your HVAC system are never normal. These can indicate debris in the system, a loose component, or something more serious that a visual inspection alone won't reveal.

It's been more than a year since your last professional service. Even with consistent filter maintenance, your HVAC system benefits from annual HVAC maintenance and inspections. A technician can catch early signs of wear, clean components you can't reach, and verify that your system is running at peak efficiency.

How to Reduce Allergens in Your Home and Improve Indoor Air Quality

If sneezing, congestion, or itchy eyes are a regular part of life at home, indoor allergens may be the culprit. Indianapolis homeowners face a unique challenge — the city sits in one of the highest pollen-count regions in the Midwest, and seasonal allergens don't stay outside. Dust, pet dander, mold spores, and mites find their way indoors year-round, recirculating through your air and triggering allergy symptoms that won't quit. Knowing how to reduce allergens in your home is the first step toward breathing easier and improving indoor air quality in your own space.

What Causes Indoor Allergens?

Indoor allergens come from many sources that Indianapolis families deal with daily. Common culprits include:

  • Pet dander from cats, dogs, and other animals
  • Dust mites that thrive in bedding, carpets, and upholstered furniture
  • Mold spores from damp areas like basements and bathrooms
  • Pollen tracked in from outside — especially brutal during Indiana's spring and fall seasons

These small-particle irritants settle into surfaces and get stirred back into the air every time someone walks through the room, runs the furnace, or simply opens a window. For Indianapolis residents already managing allergies or asthma, even low concentrations can trigger uncomfortable symptoms.

Clean Your Home Frequently to Remove Allergens

One of the simplest and most effective ways to reduce allergens in your home is to clean your home frequently and thoroughly. Here's where to focus:

Vacuum Once a Week — Minimum Use a vacuum cleaner equipped with a HEPA filter to trap small-particle allergens rather than recirculating them. Vacuum carpets, rugs, and upholstered furniture at least once a week, and more often in rooms where pets spend time. High-traffic areas near entryways and living rooms deserve extra attention, especially during Indiana's heavy pollen seasons.

Wash All Bedding Weekly Dust mites are microscopic, but their impact on allergy symptoms is anything but small. They thrive in mattresses, pillows, and bedding. Wash bedding — including sheets, pillowcases, and blankets — in hot water weekly to eliminate mites and reduce irritants at the source.

Consider Whether to Remove Carpeting If allergy symptoms are severe, it may be worth considering whether to remove carpeting in key areas like bedrooms. Hard flooring is far easier to clean and doesn't trap allergens the way carpet fibers do. Area rugs can be washed regularly and are a more allergy-friendly alternative to wall-to-wall carpet.

Clean Fabrics and Surfaces Regularly Curtains, throw pillows, couch covers, and other soft furnishings trap allergens just as effectively as carpet. Clean fabrics regularly by washing or vacuuming them, and wipe down hard surfaces with a damp cloth rather than a dry one, which simply redistributes dust into the air.

Clean Mold Before It Spreads Indianapolis basements and bathrooms are prime spots for mold growth, especially during humid summer months. Clean mold promptly with appropriate cleaners and address any moisture issues — leaky pipes, poor ventilation, or standing water — before mold can take hold and release spores into your indoor air.

Control Pet Dander Throughout Your Home

Pet dander is one of the most persistent indoor allergens, and it doesn't stay put. Microscopic dander particles float through the air and cling to furniture, walls, and HVAC filters. To get rid of dander buildup:

  • Groom pets regularly and bathe them at least once a week if allergies are a concern
  • Wash pet bedding frequently
  • Keep pets out of bedrooms and off upholstered furniture
  • Vacuum and clean home surfaces where dander accumulates

Even if no one in your household has a pet allergy, dander can act as a carrier for other allergens, compounding the problem.

Replace Air Filters Regularly

Your HVAC system is either your best ally or your worst enemy when it comes to indoor air quality. A dirty or inadequate air filter recirculates dust, pet dander, mold spores, and other allergens throughout every room in your home.

Check your air filter monthly and replace it at least every 90 days — more often if you have pets or someone in the home with asthma or allergies. Upgrading to a higher-MERV-rated air filter can dramatically improve how well your system captures small-particle allergens before they're pushed back into your living spaces.

Chapman Heating, Air Conditioning, Plumbing & Electrical's comfort specialists can help Indianapolis homeowners choose the right air filter rating for their system and allergy needs.

Install an Air Purifier for Whole-Home Allergen Control

Beyond regular air filters, installing an air purifier adds a dedicated layer of protection. A high-efficiency air cleaner can remove up to 99% of the pollen, mold spores, and other allergens circulating through your home's air. These systems also reduce household dust, smoke, and airborne pollutants that standard filters miss.

For Indianapolis families, a whole-home air purifier integrated into your existing HVAC system is a smarter investment than portable room units — it treats every cubic foot of air in the house, not just one room. The result is cleaner, fresher indoor air and meaningful relief from allergy and asthma symptoms throughout the entire year.

Manage Humidity to Reduce Mold and Mites

Both dust mites and mold thrive in high-humidity environments. Keeping indoor humidity between 35% and 50% creates conditions that are hostile to these common allergens — and more comfortable for your family.

Installing a whole-house humidifier gives Indianapolis homeowners precise control over indoor moisture levels. In winter, when forced-air heating strips moisture from the air, a humidifier relieves the irritating discomfort of dry indoor air — reducing itchy skin, scratchy throats, static electricity, and even protecting your wood floors and furniture from damage.

Because humid air feels warmer than dry air, you can keep the thermostat set lower and still feel comfortable, which can also reduce your heating costs during Indiana's cold winter months.

Chapman Heating, Air Conditioning, Plumbing & Electrical Can Help Indianapolis Families Breathe Easier

Reducing allergens in your home doesn't require one dramatic change — it requires several smart, consistent steps. From regular cleaning and air filter upgrades to whole-home purification and humidity control, each improvement compounds the last.

Chapman Heating, Air Conditioning, Plumbing & Electrical has been serving Indianapolis and the surrounding communities for decades.

Chapman Heating, Air Conditioning, Plumbing & Electrical is here to help you learn about the positive impacts installing UV lights for an HVAC system can have on your home’s indoor air quality.

What is a UV Light for an HVAC System?

UV lights for HVAC systems are lights to help clean and purify indoor air. These lights are installed in the air handler or ductwork of an HVAC system. The circulating air within a home carries germs and allergens and once it’s passed through the UV light, the air is sanitized and recirculated, boosting indoor air quality.

How Germicidal UV Lights Kill Viruses and Bacteria

Germicidal UV lights for HVAC systems create a powerful illumination capable of destroying bacteria, viruses, mold, and other airborne pathogens. Through the destruction of their DNA, they are no longer able to replicate or are simply eliminated instantly.

These lights are commonly utilized across residential and commercial settings. UV lights have long been used to treat issues like tuberculosis. Turn to Chapman for all of your air purification needs, such as air purification systems.

Types of UV Lights for HVAC Systems

Different types of UV lights for HVAC systems are designed for numerous purposes. Let’s look at two types of UV lights and how they work. 

Air Sanitizing UV Lights. Installed within the ductwork or air handler, UV light sanitizers or air sanitizing UV lights treat the air as it’s circulated through the system. By killing airborne microorganisms and cutting down on the number of contaminants, indoor air quality sees a healthy improvement. 

Coil Sanitizing UV Lights. UV light sanitizers of this variety are installed near the indoor evaporator coil of an air conditioning system. These lights are an excellent combatant to mold growth and bacteria surrounding the coil due to accumulating moisture. The UV lights can shine directly on the coil, preventing contaminants and keeping it clean.

Pros and Cons of Installing a UV Light for Your HVAC System

Before committing to a purchase, there are pros and cons of UV lights in HVAC systems to consider. Let’s walk through the pros and cons so you can make a smart and informed decision.

Pros

Improved Air Quality

With the elimination or reduction of germs, allergens, and other harmful airborne contaminants, the air of your home is safer and healthier. The improvement of indoor air quality helps maintain the health of your household. 

Odor Control

Volatile organic compounds (VOCs) are known for leaving behind unpleasant odors. UV lights for HVAC systems can reduce VOCs, acting as a means of odor control. 

Improved Airflow

UV lights improve indoor air quality by removing bacteria, mildew, and other particles. They also improve airflow. You can expect your system’s airflow to be as clean and efficient as ever before. 

Extended HVAC Lifespan

By installing air-sanitizing UV lights and coil-sanitizing UV lights, the indoor evaporator coil and ductwork of the HVAC system stay clean. This prevents component damage, corrosion, or clogging, keeping the HVAC system free of issues—further extending its lifespan. An extended HVAC lifespan means less money spent on repairs and replacements, putting more money back into your pockets. 

Reduced Allergens

The presence of allergens in your home can lead to flares in allergies and other illnesses. UV lights effectively treat and reduce allergens as they pass through the HVAC system. 

Low Maintenance

UV lights for HVAC systems are known for their minimal upkeep. The most they require is an occasional bulb replacement. This convenient benefit makes for a dependable long-term option for the improvement of your home’s indoor air quality.

Cons

High Upfront Installation Costs

HVAC UV light installation tends to run on the more expensive side. One light can cost between $100 and $1,000. In addition, proper and professional installation is required.

Limited Effectiveness

The effectiveness of UV lights is only limited to what passes through its beams. Dust particles, bacteria, and other contaminants that don’t pass through the light will be missed. 

Potential Safety Concerns

It’s important to avoid looking at or touching the UV lamp when it’s on. Exposure to UV rays is a safety concern due to its potential to damage the eyes and skin. 

Ozone, a possible byproduct, can also irritate the lungs and worsen respiratory issues. If UV lights for your HVAC system need to be replaced or cleaned, wear the proper protective equipment or call a professional. 

Not a Substitute for Proper Air Filtration

HVAC UV light installation isn’t a substitute for air filtration systems and other HVAC systems. If you utilize UV lights for HVAC systems, keep all air filters and other HVAC systems in place to remove dust and particles the lights can’t reach.

Are UV Lights the Right Choice for Your Home’s HVAC System?

While UV lights for HVAC systems can’t eliminate every particle within a home, they are still a helpful and worthwhile investment for homeowners looking to improve indoor air quality. UV lights work best as part of a broader indoor air quality strategy that targets multiple types of contaminants.

For example, adding a whole-home air purifier can help capture airborne particles like dust, pollen, and pet dander, while humidifiers can restore moisture during dry winter months to improve comfort and respiratory health. In more humid conditions, dehumidifiers help reduce excess moisture that can contribute to mold growth and poor air quality.

By combining UV lights with these indoor air quality solutions, homeowners can create a more balanced, healthier indoor environment year-round.

Keeping the air in your home of the highest quality is a big responsibility. One area is your home’s air ducts, which play an integral role in indoor air quality. Bacteria, allergens, and other airborne contaminants can lead to a decrease in your home’s air quality, which isn’t great for your quality of living. A treatment option to address these concerns is air duct sanitizing

The experts at Chapman Heating, Air Conditioning, Plumbing & Electrical are here to help you understand the ins and outs of air duct sanitizing and disinfecting and its importance.

Understanding the Differences Between Air Duct Sanitizing, Cleaning, & Disinfecting

While air duct cleaning and air duct sanitizing are important on their own, they do serve different purposes.

What is Air Duct Cleaning?

Air duct cleaning is a process that removes dust and debris from air ducts. Air duct cleaning services typically utilize powerful vacuums to suck out dirt, grime, and other debris to clean and clear the air ducts.

What is Air Duct Sanitizing?

Air duct sanitizing is a chemical-based process aimed at killing the presence of bacteria and mold within the air ducts. Mold growth and bacteria in your air ducts can potentially cause and spread illness. Air duct sanitizing is part of the solution to keep the home healthy and to prevent this possibility. Air duct sanitizing and disinfecting refer to the same air purification service.

Air duct cleaning does improve indoor air quality, but it isn’t the primary solution. A routine schedule of air duct sanitizing for your home keeps the development of mold and bacteria within the air ducts at bay.

Is Sanitizing Air Ducts Necessary?

Yes, it is. Sanitizing your home’s air ducts is an essential component of addressing the growth of mold and even a vermin infestation. Without air duct sanitizing, the potential for mold growth, infestation, and a decline in your home’s indoor air quality becomes more likely. 

Protect Your Home from Mold & Vermin with Regular Air Duct Sanitization

When it comes to mold, spores are attracted to areas of previous growth and will stick there. The products used during air duct sanitizing effectively kill mold spores and are an excellent deterrent to preventing them from growing in previously affected areas.

Occurrences of a vermin infestation aren’t easy to tackle. Thankfully, air duct sanitizing can help make the process easier. Unlike standard air duct cleaning, air duct sanitizing can effectively remove animal scents and territorial markings. This makes the possibility of a reinfestation far less likely to occur in that area.

When Should You Sanitize and Disinfect Your Air Ducts?

The general guideline for homeowners to follow is scheduling air duct sanitizing every two to three years. However, there is no downside to reducing the amount of time between services. It’s also important to keep in mind your air ducts need to be free of dust and debris before sanitization. 

By following these recommendations, you can prevent mold and bacteria from building in your air ducts while maintaining healthy indoor air quality.

This winter has been mild so far, but we still have a long way to go before we're through the cold season. As the temperature drops lower, people crank the heater to stay toasty warm on cold, dark nights.

Warm air is great for cozy nights' sleep, but when the air heats up it loses moisture, leaving you with dry air that affects your skin, health, and even your home's structure. A whole-home humidifier is the best way to add moisture back into the air and keep your entire house comfortable.

Why Dry Air Is a Problem in Winter

When your heating system runs, it strips moisture from the air. This creates an uncomfortable environment that can lead to:

These issues compound over the winter months, making your home less comfortable despite running your heater constantly.

What Are the Benefits of a Whole Home Humidifier?

Health and Comfort Benefits

Whole-house humidifiers prevent common winter annoyances and provide significant health advantages:

Respiratory Health

Skin and Personal Comfort

Energy Savings
Because humidified air feels more comfortable, you can enjoy comfort at cooler temperature settings to help save energy and money over the winter. Many homeowners find they can set their thermostat 2-3 degrees lower while maintaining the same comfort level.

Humidifier Benefits for Your Home

Adding moisture to your home helps protect your investment:

These structural benefits alone can save you thousands in repair and replacement costs over time.

Improved Air Quality Throughout Your Home

Unlike portable units that only humidify one room, house humidifiers that connect to your HVAC system deliver consistent moisture levels throughout your entire home. This means:

How Does a Whole-Home Humidifier Work?

Whole-home humidifiers attach directly to your HVAC system. They run through your air duct system and deliver humidity to your home evenly and automatically.

The process is simple:

  1. Your thermostat signals your heating system to run
  2. The humidifier activates simultaneously
  3. Water vapor is added to the air passing through your ducts
  4. Humidified air is distributed evenly to every room
  5. A humidistat monitors and maintains optimal moisture levels

When properly maintained, these units will last for years and are a great addition to the overall health and comfort of your home.

Wondering why your AC unit is freezing up in the hottest months of the year? You might ask yourself, “How is it that it’s 90 degrees outside and my AC unit has frost buildup?” This issue actually happens to be a very common problem and can lead to further HVAC complications.

So, why is your AC unit freezing up? And, what can you do to prevent this from happening? It’s important to understand the causes and preventive measures to tackle this common air conditioning issue.

What Causes an AC Unit to Freeze Up?

Low AC Refrigerant

Your AC unit requires a certain amount of refrigerant to guarantee the best cooling performance. When the refrigerant falls under the required amount, the balance will be thrown off and lead to your air conditioner freezing.

If you spot frozen coils, this is a common sign your air conditioner has low refrigerant levels. Contact a professional technician to restore your air conditioner’s refrigerant levels and mitigate the possibility of future AC problems.

Dirty Air Filters

One of the most common factors that leads to your AC freezing up is a dirty air filter. Your air conditioner’s air filter can become dirty due to debris buildup and dirt accumulation. This will then lead to a lack of airflow into your AC system and cause it to overwork itself, resulting in a freeze. Monitor your air filters and change them regularly to avoid a frozen AC unit.

Broken or Clogged Coils

A broken or clogged evaporator coil can also lead to a frozen AC unit. Evaporator coils may become clogged due to dirt and dust buildup or they can become corroded over time and break and lack efficiency. These issues compound and lead to unusual temperatures, leading to ice buildup.

Blocked Air Vents

A blocked air vent is caused by the same debris and dirt buildup seen with dirty air filters. The same cause leads to the result, a frozen AC unit. Check your air vents regularly and clean and vacuum them when necessary.

Damaged Blower Motor

The blower motor in your air conditioning system plays a key role in keeping your home cool. If the blower motor becomes damaged or fails altogether, this can cause your AC unit to freeze and cease working. Hearing a rattling sound while it’s trying to operate indicates something is wrong with it. Issues with a blower motor are a more complex issue and an HVAC technician should be consulted if the blower motor is the culprit.

Clogged Condensate Drain Line

Your AC’s condensate drain line is responsible for removing water created in the cooling system and disposing it away from your home. The condensate drain line can become clogged due to dirt, mold, or debris and the created excess moisture can flow into your AC unit and home, possibly causing issues to both. And ultimately, freeze your air conditioning coils.

How to Stop Your Air Conditioner From Freezing Up

Now that the causes of this problem have been established, what are the ways to prevent a frozen AC unit? Use these tips as an added layer of protection against freeze buildup.

1. Check Refrigerant Levels

Have an HVAC technician inspect your refrigerant levels to determine if your AC unit needs or is sufficient for the time being.

2. Replace Your Air Filter

You should practice regularly checking your AC’s air filters. Inspect the air conditioner’s air filters for debris or dirt buildup and clean or replace them every one to two months. This will improve your air conditioner’s performance and the quality of air. Replacing a dirty or clogged air filter can lower your air conditioner’s energy consumption by 5% to 15%.

3. Inspect the AC Drain Line

It’s important to check your AC drain line throughout the summer, but using a dry/wet shop vacuum to remove debris and other buildup will help you prevent a frozen AC unit. You can also turn to an HVAC specialist to help with this preventive measure.

4. Keep Vents Open

Keeping your vents open and free of blockages is one of the easiest ways to prevent a frozen AC unit. Avoid closing more than two or three vents at any given time.

5. Contact an HVAC Technician to Inspect Your Fan

Your blower motor’s fan is a vital piece of equipment to help generate airflow. This is often difficult to do on your own, so contact an HVAC technician to inspect your fan. Keeping the blower motor’s fan in working order is an important step to prevent a frozen AC unit.
