Real Story: Water Heater Repair Near Lampson and Euclid
One of our recent calls came from a family-owned pho shop near Lampson and Euclid. They’d started getting lukewarm water during lunch rush and thought it was a usage issue. Turned out the gas valve was sticking and the burner wasn’t lighting fully. The unit was under 5 years old—still good overall. We cleaned the thermocouple, replaced the valve, and it fired right back up. They didn’t miss a beat. Owner even offered us a free bowl after.
How Commercial Water Heater Repairs Work
Commercial systems are built stronger than home models, but they still break down—especially with daily use. Repairs can include fixing the gas burner, replacing the thermostat, resetting the control board, or flushing out sediment that’s blocking the heat exchanger.
We start with a basic function check and use new technology tools like thermal readers, leak detection sensors, and combustion testers. Once we’ve got the issue pinned down, we get the part replaced or cleaned. For gas units, we pressure check the line and test the draft. For electric ones, we test all circuits and reset the limit switches.
Some issues look big but turn out simple—like an unplugged igniter wire or a tripped breaker. Others, like a failing heat exchanger or leaking tank, may need more extensive work or even a replacement quote.
Average 2025 repair cost for commercial water heaters in Orange County is $450 to $1,850, depending on what’s failed and what type of heater you have.

Common DIY Mistakes With Commercial Water Heaters
One business owner tried flushing the tank himself using a garden hose. Problem was, he forgot to turn off the gas first. Burned out the bottom burner and cost him triple what a flush would’ve run.
Another gym in Garden Grove swapped out the thermostat without checking the voltage. Wrong model blew out the circuit board, and it had to be replaced entirely.
We’ve also seen folks try to “clean the flame sensor” by scrubbing it with steel wool. That actually removes the coating and makes it unusable. A $30 part became a full-day headache.
