A Little Maintenance Goes a Long Way
Dirty coils and clogged filters make your system work harder, cost more to run, and wear out sooner. A tune-up cleans the condenser and evaporator coils, checks refrigerant levels and electrical parts, and catches small problems before they turn into a no-heat or no-cool call.
We also change filters for customers who’d rather not deal with it, including units in attics, crawl spaces, and basements that are hard to reach.

FAQ
Maintenance Questions
What homeowners ask about keeping a system running.
How often should I have my system serviced?
Twice a year is common: the AC before summer and the furnace before winter.
Can you change filters in an attic or basement?
Yes. That’s one of the most common requests we get from older customers.
Do you maintain commercial rooftop units?
Yes. See Commercial HVAC & Refrigeration.
Why does coil cleaning matter?
The coils move heat in and out of your home. When they’re coated in dust, the whole system works harder and cools or heats less.
