Frequently Asked Questions

How quickly can someone get to my home?
RT Olson dispatches calls 24 hours a day, 7 days a week, including weekends and holidays. Response time depends on your location and how many calls are ahead of yours, but the team prioritizes active leaks, no-heat calls in cold weather, and AC failures during heat events. Call (951) 344-5596 and a dispatcher can give you a realistic arrival window based on current availability.
Do you offer free estimates?
Call (951) 344-5596 to ask about estimates for your specific situation — diagnostic fees and estimate policies can vary depending on the type of work and whether the job is an emergency. For planned work like water heater replacements or HVAC installs, the team can typically walk through pricing before any work begins so there are no surprises.
What should I do while I wait for the plumber to arrive?
If you have an active leak, locate your main water shutoff and turn it off — in most Corona homes it's near the front of the property by the meter, or inside a utility closet. For a water heater leak, shut off the cold-water supply line feeding the tank as well. If you smell gas at any point, leave the house immediately and call SoCalGas before calling a plumber.
Are you licensed to work in California?
Yes — RT Olson Plumbing, Heating and Air Conditioning holds California contractor license #997337. You can verify the license status directly through the California Contractors State License Board (CSLB) website. Licensed contractors are required to carry insurance and meet state standards for the work they perform.
Do you handle both plumbing and HVAC, or do I need separate contractors?
RT Olson handles plumbing, drain cleaning, water heater service, and heating and air conditioning — so one call covers most of what a home needs. That's especially useful for property managers dealing with multiple issues across units, or homeowners who discover a plumbing problem and an HVAC issue at the same time.

Looking for the best plumber in Corona? When a pipe bursts at midnight, a water heater stops heating, or your AC quits on a July afternoon in the Inland Empire, RT Olson Plumbing, Heating and Air Conditioning is available around the clock to get your home back to normal. Serving Corona and the surrounding area since 2014, the team handles plumbing repairs, drain cleaning, water heater service, and heating and air conditioning work — all under one license (#997337).

Services we handle

Plumbing repair and leak detection — From a dripping faucet to a slab leak you can feel as a warm spot through your tile, plumbing problems rarely wait for a convenient moment. Fast diagnosis keeps a small leak from becoming a flooded room.

Drain cleaning — Slow drains in a Corona home often mean years of buildup in cast-iron or galvanized lines, especially in older neighborhoods. Clearing the line properly — not just punching a temporary hole through the clog — is the difference between a fix that lasts and one that doesn’t.

Water heater service and replacement — That low rumbling from your water heater closet is sediment baking onto the tank floor, a sign the unit is working harder than it should. Whether your system needs a flush, a new anode rod, or a full replacement with a tankless unit, the right call now saves a cold-shower surprise later.

Heating and air conditioning — Inland Southern California swings from triple-digit summers to cold desert nights, and your HVAC system takes the full range. RT Olson handles repairs, maintenance, and system replacements for both heating and cooling so you’re covered no matter what the season throws at you.

Why homeowners and property managers call us

RT Olson has been working in Corona since 2014, long enough to know the housing stock — the tract homes built in the 1980s and 90s with original copper supply lines, the newer master-planned communities on Temescal Valley’s hillsides, and everything in between. That familiarity matters when a technician needs to trace a line through a wall or pull a permit quickly.

The team is available 24 hours a day, 7 days a week. That’s not a marketing line — it means a dispatcher picks up at 2 a.m. when the hissing sound behind your wall won’t let you sleep. Licensed under California contractor license #997337, the company carries the credentials required to work on your home legally and to pull permits when the job calls for it.

Property managers especially appreciate a single point of contact for plumbing and HVAC across multiple units. One call handles the broken garbage disposal in unit 4 and the AC that’s not cooling in unit 12, without coordinating between separate contractors.

Service area

RT Olson is based in Corona and regularly serves homeowners and businesses throughout the surrounding Inland Empire and Riverside County communities. If you’re in Norco, Eastvale, Riverside, or Chino Hills, you’re well within the service footprint. The team also covers calls in Anaheim Hills and other nearby areas — call (951) 344-5596 to confirm coverage for your address.

Corona’s location at the junction of the 91 and 15 freeways means technicians can reach most of the western Inland Empire without the kind of drive time that turns an urgent call into a long wait.


If you’re reading this right now, there’s a good chance something in your home isn’t working the way it should. You don’t need a sales pitch — you need someone to pick up the phone. Call RT Olson Plumbing, Heating and Air Conditioning at (951) 344-5596 any time, day or night, and get a real person on the line.
