Serving Inland Empire
Plumbing, Heating & Air in Corona, CA
24/7 plumbing, drain & sewer, water heater, heating, AC, and indoor air service for Corona — with real people answering around the clock.
Corona sits squarely in our home territory — Power Pro has served Riverside County homeowners for 20+ years from three local offices, and your call is dispatched from the Anaheim office nearby. Same-day appointments, upfront written pricing, and a price match guarantee come standard.
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.

Electric utility & rebates
Corona homes get electric service from Southern California Edison (SCE). 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.
