Replacing an AC in Temecula in 2026

New air conditioners and heat pumps now use lower-GWP refrigerants such as R-454B and must meet SEER2 efficiency minimums. Under California's Title 24 Energy Code, replacing an outdoor unit, air handler or coil usually means a permit, duct leakage testing and third-party verification. We'll walk you through what your job needs before work starts.

Sized for Temecula heat

Temecula sits in a valley where afternoon ocean air pushes in through the Rainbow Gap, so evenings cool off faster than in the inland cities. Summer highs still average in the mid-80s, with regular heat waves in the high 90s and 100s, and winter nights dip into the 30s and low 40s.

Temecula homes we work on

Most Temecula homes were built from the late 1980s on: two-story stucco tracts in Paloma del Sol, Harveston and Wolf Creek, hillside homes in Redhawk and Crowne Hill, and estates out toward Wine Country. Many have attic ducts and attic or garage air handlers, and a lot of the original equipment from the 2000s building boom is now reaching the end of its life.
