An Over the Moon HVAC tune-up covers safety, cleaning, and performance checks. Technicians tighten electrical connections, check thermostat operation, measure temperature difference, flush condensate drains, and lubricate moving parts. For AC: clean condenser coils, monitor refrigerant pressures/temps, clean drains/pans/pumps, check for leaks, and clean the accessible evaporator coil. For heating: inspect the heat exchanger, clean burner and ignition parts, monitor flue draft, and adjust gas pressure while checking for leaks. Filter service and startup/operation tests are included for Waukesha homes.

"Shawn M. Was knowledgeable and very transparent with any issues that arose or potential future issues." — Trevor K.
An AC tune-up service includes a systematic inspection, cleaning, and adjustment of your cooling system to restore efficiency, reduce breakdown risk, and extend equipment life. Most performance losses come from dirt buildup and airflow issues, so technicians focus on airflow, electrical health, and safe operation first. Our team follows a precise checklist on every visit, and we regularly perform these checks for homeowners in and around Merton.
What a typical AC tune-up covers:
- Inspecting and cleaning ducts to improve airflow
- Checking thermostat settings and making needed adjustments
- Examining electrical connections for safety and efficiency
- Testing startup, normal operation, and shutdown sequences
- Cleaning or replacing air filters for better air quality and performance
- Lubricating moving parts to reduce friction and wear
If your system short cycles, runs longer than normal, or airflow feels weak, schedule a tune-up before peak heat to prevent bigger repairs.
