Spring AC Tune-Up Checklist: What We Do (and What You Can Do)

A spring tune-up is the easiest way to prevent mid-July breakdowns and high bills. Here’s what our technicians do during a precision AC tune-up, plus a simple homeowner checklist to keep your system happy between visits.

What our technicians do (pro checklist)

• Deep coil cleaning (where accessible) to restore heat transfer and capacity.

• Refrigerant charge check using superheat/subcool to manufacturer spec.

• Electrical inspection of capacitors, contactor, wiring, and compressor protection.

• Airflow & temp split verification; we note duct restrictions or dirty blower wheels.

• Drainage: clear condensate lines/pans to prevent water leaks.

• Controls & thermostat calibration; verify staging/communicating settings.

• Documentation: we record readings and recommendations so you can see trends.

Homeowner to-dos (10–15 minutes)

• Change your filter (every 1–3 months; more often with pets).

• Clear 2–3 feet around the outdoor unit; trim shrubs and remove leaves.

• Open supply vents and ensure returns aren’t blocked by rugs or furniture.

• Check your thermostat schedule and batteries (if applicable).

• Peek at the drain line—if you see water around the air handler, call us.

Why tune-ups pay for themselves

• Fewer breakdowns: small fixes now prevent big repairs later.

• Lower energy bills: clean coils + correct charge = efficiency.

• Longer system life: less stress on motors and compressor.

• Warranty compliance: most manufacturers require documented maintenance.
