Professional Generator Maintenance and Tune-Up in Indianapolis, IN

When the weather turns rough in Indiana, the last thing you want is a generator that will not start. Routine maintenance keeps it ready for the next power outage. At Chapman Heating, Air Conditioning, Plumbing & Electrical, we make sure your system works when it matters most.
We have been serving Indianapolis and the surrounding areas for more than forty years. Our electricians maintain all major generator brands, including Generac and Kohler. Hoosiers call us because we work fast, communicate clearly, and treat every job like it is our own home.
What’s Included in Our Generator Maintenance Service
A generator is a hardworking machine, and it needs attention just like your furnace or air conditioner. During each tune-up, we go through a complete checklist to keep it running safely and efficiently.
- Replace oil and air filters if needed
- Check fuel lines and fittings for leaks or corrosion
- Test-start the generator under load to confirm performance
- Inspect transfer switch connections
- Check and clean the battery terminals and test voltage
- Clean air intakes, cooling fins, and the generator housing
- Clear error codes or alarms on the control panel
- Log maintenance details and review them with the homeowner
Everything we do follows manufacturer recommendations, whether your generator came from Generac, Kohler, or another brand. Our goal is to keep your backup system reliable and within warranty guidelines.
How Often Should You Schedule Generator Maintenance
Most Indy homeowners schedule maintenance once or twice a year depending on how often their generator runs. We usually recommend a tune-up before storm season and again before winter.
You might also need service sooner if you notice:
- Slower startup during self-tests
- New noises or smoke while it runs
- Warning lights or alarms on the control panel
The best time to call is before a problem gets worse. Routine maintenance is always cheaper than emergency repairs or replacement.
Benefits of Regular Generator Tune-Ups
Taking care of your generator gives you peace of mind and keeps your home protected through every season.
- Reliable power during outages
- Lower fuel use and better efficiency
- Fewer unexpected breakdowns
- Longer equipment life
- Keeps warranty protection active
For Hoosiers, power reliability means safety and comfort when the weather turns bad. That is why we take these tune-ups seriously.

Prevent Future Repairs with Regular Generator Maintenance
Most major breakdowns start with small issues like dirty filters or weak batteries. Regular service helps catch those problems before they cause bigger ones. Our electricians perform load tests and full inspections to keep your generator ready for anything.
