What do Energy Efficiency Ratings Mean?

Posted on: August 10, 2015 | , ,

We often put a lot of emphasis on purchasing units that are ‘energy efficient.’ But what does that actually mean? It’s time to shed some light on energy efficiency ratings so the next time you’re in the market for a new unit, you’ll know the right questions to ask. Here are some basic facts about energy efficiency ratings.

Energy efficiency ratings play an important role in determining how much you will spend on a system and its operating costs. Seasonal energy efficiency ratio (SEER) and energy efficiency ratio (EER) are the two efficiency ratings used to measure a systems performance. A unit with a higher SEER and EER will equal lower operating costs, but will come with a higher price tag.

Let’s dive a little deeper into these efficiency ratings. When it comes a SEER efficiency rating, the higher the number, the more energy efficient the cooling system is. SEER efficiency rating around found on central air conditioning systems. A 10 SEER air conditioner won’t be as energy efficient as a 13, 16 or 20 SEER air conditioner. An older model will have a lower SEER number, which means you will end up paying more money each month on your energy bill.

An EER efficiency rating applies to room air conditioning units. Room air conditioners cool rooms, like the name would suggest, rather than an entire home or business. Room air conditioners are less expensive to operate than central units. Choosing the right size room air conditioner is very important. A small unit running for an extended period of time operates more efficiently than a large unit that cycles on and off too frequently. Always consult with an HVAC contractor before you make a purchase to get an expert opinion on the right unit for your needs.

When it comes to understanding energy efficiency ratings, things can get tricky. Understanding which energy efficiency rating applies to which air conditioning unit will greatly help when it comes time to purchase a new unit. If you still have questions, don’t be afraid to ask an HVAC contractor. They will be able to provide the right answers and guide you in the right direction.
