The 12-Point AC Tune-Up Checklist Every South Carolina Homeowner Needs Before Summer

AC repair technician servicing an outdoor air conditioner condenser in South Carolina

Why spring, not July

Every HVAC company in the state is slammed the first week temperatures hit 95. A tune-up in March or April finds the weak capacitor and the low charge while there is still time to fix them on your schedule.

The 12 points

Clean the outdoor condenser coil. Inspect the indoor evaporator coil. Test the capacitor under load. Inspect the contactor. Measure compressor and fan amperage. Verify refrigerant charge by superheat and subcooling. Flush the condensate drain and treat for algae. Tighten every electrical connection. Check blower wheel and motor. Replace the filter. Calibrate the thermostat. Record the temperature split at the vents.

What it prevents

Frozen coils, tripped breakers, water leaks through the ceiling, compressor failure from low charge, and the 7 p.m. no-cool call on the Fourth of July.

Maintenance plans

Two visits a year, priority scheduling and a repair discount. For most homeowners the plan costs less than one emergency call.
