How Often Should You Service Your HVAC System?
Understand recommended HVAC maintenance intervals for furnaces, boilers, air conditioners, heat pumps, and ductless systems in Connecticut.
A useful starting point
Most residential heating and cooling systems benefit from professional maintenance at least once a year. Systems used for both heating and cooling may benefit from checks before each major season, depending on manufacturer guidance and operating conditions.
What maintenance can include
Depending on equipment, a visit may involve checking electrical connections, condensate drainage, refrigerant-related performance, airflow, filters, safety controls, combustion, and general operation. The exact checklist differs for a boiler, furnace, air conditioner, or heat pump.
What homeowners can do
Replace or clean filters as directed, keep outdoor equipment free of leaves and snow, and make sure supply and return grilles are unobstructed. Never open sealed electrical or refrigerant components yourself.
Why it matters
Maintenance can help identify small issues before they interrupt comfort. It does not guarantee that equipment will never fail, but it supports safer operation, performance, and a better understanding of system condition.
