Air Conditioning in Corona, CA
Licensed air conditioning pros serving Corona and the surrounding Inland Empire area — 24/7, with same-day appointments.
Corona 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 Anaheim office, so a licensed, background-checked technician is genuinely nearby, not "in your area" in name only.
The Inland Empire sees the hottest sustained summer temperatures in the service area, so correct AC sizing and duct sealing directly affect comfort and utility bills. Housing runs from Craftsman-era cores in Riverside and San Bernardino to 2000s stucco tracts in Eastvale and Chino. Local groundwater is very hard, so scale management on water heaters is a constant.
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.
Corona facts that shape air conditioning work
Electric utility & rebates
Corona is Southern California Edison (SCE) electric territory, which sets the incentive when a worn-out AC is replaced with a heat pump. Corona's city utility serves only a few small areas, such as Dos Lagos and The Crossings. Replacing a central AC with a heat pump in SCE territory brings SCE's $300+/ton instant discount, applied at purchase through participating distributors — roughly $900+ on a typical 3-ton system; SCE lists it as limited-time.

Climate zone
Corona falls in Building Climate Zone 10 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 Corona AC permit we file.

Housing age
24.6% of Corona's 50,799 housing units — about 12,500 — were built before 1980, and the median year built is 1991 (Census ACS 2020–2024), which makes the typical unit 35 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 Corona air conditioner.

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