The Spring & Fall Tune-Up Checklist That Adds Years to Your System

Your HVAC system is the hardest-working appliance in your home, and like any machine, it needs regular care. Two tune-ups a year — one in spring before cooling season, one in fall before heating season — is the single best way to extend equipment life and keep energy bills low.

On a cooling tune-up, we clean the condenser coils, check refrigerant charge, inspect electrical connections, clear the condensate drain, and verify airflow across every register. Low refrigerant and dirty coils are the top two causes of high summer bills and premature compressor failure.

On a heating tune-up, we inspect the heat exchanger for cracks (a carbon-monoxide safety issue), check the igniter and flame sensor, test the inducer motor, and confirm the thermostat cycles correctly. A cracked heat exchanger is a safety emergency — catching it early protects your family.

Both visits include a filter check. A clogged filter is the #1 cause of avoidable breakdowns and high bills. We'll show you the right filter and the right replacement schedule for your system.

The best part? A tune-up costs far less than a single emergency repair. Book both your spring and fall visits with one call to (314) 210-6487, and Kim's family will keep your system running like new for years to come.
