Tankless Water Heater Installation, Repair & Maintenance
Endless hot water and lower gas bills. We install, descale and repair tankless water heaters from every major brand.
Why homeowners choose tankless
- Endless hot water. A tankless unit heats water as it flows, so back-to-back showers never run cold.
- Lower energy bills. With no tank to keep hot around the clock, a gas tankless unit costs less to run than a gas tank.
- More space. It mounts on the wall, freeing up the corner of your garage or closet.
- Longer life. Well-maintained tankless units typically last 15–20 years.
Tankless and Inland Empire hard water
Hard water is the number-one cause of tankless trouble here. Minerals build up inside the heat exchanger and lead to lukewarm water, fluctuating temperatures and error codes. Descaling (flushing) the unit about once a year keeps it efficient and protects the warranty. We descale and service Rinnai, Navien, Noritz, Takagi, A.O. Smith and other brands.
Sizing a tankless water heater
Tankless units are sized by flow (gallons per minute), not gallons stored. A typical shower uses about 2 gallons per minute, so a household that runs two showers and the dishwasher at once needs a bigger unit than a couple living alone. We size it to how your family actually uses hot water.
Switching from a tank to tankless
Converting usually means a larger gas line, new venting and a dedicated electrical outlet. We look at all of that first and give you a clear price, so there are no surprises.

Questions we hear a lot
Is tankless worth it in Southern California?
For many homes, yes, especially larger households, homes with soaking tubs, or anyone who wants to free up space. You pay more upfront than for a tank, but you get endless hot water, lower gas use and a longer life.
Why does my tankless water heater go cold in the middle of a shower?
Common causes are mineral buildup from hard water, a clogged inlet filter, low gas supply, or a flow rate too low to keep the burner on. Descaling fixes many cases. Text us the model and any error code, or look it up in our tankless error codes.
How often should a tankless water heater be descaled?
About once a year in the Inland Empire because of our hard water. Homes with a water softener can often go longer. See tankless descaling and maintenance.
Do tankless water heaters give instant hot water?
No. Hot water still has to travel through the pipes to the faucet. A recirculation pump can bring hot water to far bathrooms much faster.
