Air Conditioning in Pasadena, CA
Licensed air conditioning pros serving Pasadena and the surrounding San Gabriel Valley area — 24/7, with same-day appointments.
Pasadena homeowners have called Power Pro first for 20+ years — for everything from middle-of-the-night emergencies to planned upgrades. Your service is dispatched from our Cerritos office, so a licensed, background-checked technician is genuinely nearby, not "in your area" in name only.
The San Gabriel Valley runs noticeably hotter than the coast in summer, so properly sized air conditioning is essential rather than optional. Postwar slab-on-grade tracts make slab leaks a familiar local failure, and groundwater-served areas have some of the hardest water in the county. Many 1950s–60s homes are on their original galvanized supply piping.
Every visit starts the same way: we diagnose, explain your options in plain language, and put exact pricing in writing before any work begins. We back it with a price match guarantee and a 100% satisfaction guarantee — and 1,400+ Google reviews across Los Angeles & Orange County keep us honest.
Pasadena facts that shape air conditioning work
Electric utility & rebates
Pasadena is Pasadena Water and Power (PWP) electric territory, which sets the incentive when a worn-out AC is replaced with a heat pump. Pasadena Water and Power (PWP) is municipal, so SCE's instant heat pump discounts do not apply; Pasadena Water and Power (PWP) runs its own programs, which we confirm job by job before quoting a heat pump.

Climate zone
Pasadena falls in Building Climate Zone 9 on the California Energy Commission's list. Title 24's requirements for replacement cooling equipment vary by climate zone, so the zone is part of every Pasadena AC permit we file.

Housing age
72.2% of Pasadena's 63,203 housing units — about 45,630 — were built before 1980, and the median year built is 1961 (Census ACS 2020–2024), which makes the typical unit 65 years old. In homes that age, existing duct sizing and electrical panel capacity often set the limits for a new AC, so we check both before sizing a Pasadena air conditioner.

Permits
AC and heat pump change-outs in Pasadena require a mechanical permit and a final inspection, and we file the permit with the job. The permit office for Pasadena is the City of Pasadena Building & Safety Division.
