24/7 Plumbing, Heating and Air in Corona

When a pipe bursts at midnight or the AC quits on a 100-degree Inland Empire afternoon, RT Olson Plumbing, Heating and Air Conditioning is the number to call. Serving Corona and the surrounding Inland Empire since 2014, the team handles residential and commercial plumbing, heating, and air conditioning — available around the clock, any day of the year.

Services we handle

Plumbing — From a dripping faucet that’s running up your water bill to a slab leak hidden beneath a concrete foundation, the plumbing side covers diagnostics, repair, and full replacement. Corona’s older neighborhoods often run copper or galvanized supply lines that corrode from the inside out long before they show a stain on the wall.

Drain and sewer — Slow drains, recurring clogs, and sewer line backups are more than a nuisance — raw sewage backing into a tub is a health issue that needs same-day attention. Camera inspection takes the guesswork out of what’s happening underground.

Heating — When a furnace stops mid-January, a forced-air system that won’t ignite is more than uncomfortable. The heating side covers gas furnaces, heat pumps, and system tune-ups before the cold sets in.

Air conditioning — Southern California’s dry heat is relentless from May through October. Whether a refrigerant line is leaking, a capacitor has failed, or an aging unit simply can’t keep up with the load, AC repair and replacement are core to what the team does every day.

Why homeowners and property managers call us

RT Olson has been working in Corona since 2014 — long enough to know the housing stock, the local water quality, and the permitting process at the City of Corona Building Department. That matters when a repair requires a permit pull or when hard water scale has quietly been destroying a water heater from the inside.

The license is on file with the California Contractors State License Board (#997337), which means the work is bonded and meets state code requirements — not just a handshake estimate from an unlicensed tech. That distinction protects you when a homeowner’s insurance carrier or a property management company needs documentation.

Availability is 24 hours a day, 7 days a week. Plumbing and HVAC problems don’t schedule themselves around business hours, and a water main shutoff valve that won’t close at 2 a.m. can’t wait until Monday morning.

Communication is straightforward: you get a real assessment of what’s wrong, what it will take to fix it, and what the cost looks like — before any work begins.

Service area

The primary service area is Corona, CA, with regular coverage extending to Norco, Riverside, Eastvale, and the broader western Riverside County corridor. If you’re in the Inland Empire and unsure whether you’re in the service zone, call (951) 344-5596 — the team will tell you directly.

Corona sits at the western edge of Riverside County, where the Santa Ana winds push summer temperatures well past 100°F and where water pressure fluctuations are common near the foothills. Those conditions accelerate wear on pressure regulators, water heaters, and AC condensers in ways that homeowners in coastal climates rarely see.

If you’re reading this right now, there’s a good chance something has already gone wrong. Call (951) 344-5596 — day or night — and get a technician on the way instead of spending another hour searching.
