What a Good AC Tune-Up Includes
- Cleaning the outdoor coil, which monsoon dust coats every summer.
- Checking the refrigerant charge and looking for leaks.
- Testing the capacitor and contactor, the parts most likely to fail in the heat.
- Flushing the condensate drain so the float switch doesn't shut the system off.
- Checking the indoor coil and the filter.
AC Tune-Up Cost and the TEP Rebate
An AC tune-up in Tucson typically costs $70 to $200, based on HomeGuide's 2026 averages. TEP pays toward specific work done by a participating contractor: $80 for a refrigerant charge repair and $40 each for indoor and outdoor coil cleaning, up to $160. See TEP rebates for AC.
When to Book
Book your AC tune-up in Tucson in March or April, before the first 100° week. Tucson averages 68 days a year above 100°F, and 2024 set the record with 112. A dirty coil or weak capacitor is a small fix in spring and an emergency AC repair in July.
