About RT Olson Plumbing, Heating and Air Conditioning

RT Olson Plumbing, Heating and Air Conditioning has been serving Corona and the surrounding Inland Empire since 2014. The company was built around a straightforward idea: homeowners dealing with a burst pipe, a failed water heater, or an air conditioner that quits in the middle of a July heat wave deserve a crew that shows up prepared — not one that schedules a look-see for next week.

What we do

On any given day, that means dispatching to a slab leak that a homeowner first noticed as a warm, damp patch on the tile floor, diagnosing a furnace that stopped mid-cycle, or clearing a main line that backed up into a first-floor bathroom at midnight. Because plumbing and HVAC failures rarely wait for business hours, we run a 24/7 dispatch line — (951) 344-5596 — so there is always a live person to take the call. The work itself is physical and diagnostic in equal measure: reading water pressure, tracing refrigerant lines, pulling permits, and explaining to a stressed homeowner exactly what is happening inside their walls before a single tool touches anything.

Our certifications and licensure

RT Olson Plumbing, Heating and Air Conditioning holds California Contractors License #997337. A state license is the baseline legal requirement to pull permits and perform work on residential and commercial systems in California — it means the work is inspectable and that the company carries the required bonding and insurance. We keep our licensing current because the permit process protects the homeowner as much as it does the contractor: an uninspected repair can complicate a home sale or an insurance claim down the road.

Where we work

Corona sits at the western edge of Riverside County, where the Inland Empire transitions toward the hills of the Santa Ana Mountains. The housing stock ranges from post-war tract homes in the older neighborhoods near downtown to newer construction in master-planned communities built out through the 2000s. Older homes often carry galvanized supply lines that have narrowed with decades of mineral buildup — Southern California’s hard water accelerates that process noticeably. Newer construction brings its own patterns: PEX manifold systems, tankless water heaters, and multi-zone HVAC setups that need technicians familiar with the equipment. Beyond Corona, we regularly work throughout Riverside, Norco, Eastvale, Chino Hills, Ontario, and neighboring communities across the region.
