Tankless Water Heater Repair and Service in Arcadia
One truck, nine tankless services, all built around Arcadia's water and housing stock. Whether you need tankless water heater repair near me Arcadia CA or a scheduled flush before winter, we handle the whole unit: gas side, water side and electronics.

01
Tankless Water Heater Tune-Up
A tune-up flushes scale with a descaler pump and flush kit, checks inlet gas pressure with a manometer, and verifies flame quality. Recommended every 12 months in Arcadia, where hard water shortens heat exchanger life. Most tune-ups take 60 to 90 minutes.
View service 02Tankless Water Heater Inspection
A full inspection covers the heat exchanger, igniter, gas valve, flow sensor and pressure relief valve, plus a combustion analyzer reading on the exhaust. We document what we find with photos. Ideal before buying a home in Santa Anita Oaks or after any error code.
View service 03Tankless Water Heater Winterization
Winterization drains the unit, isolates the gas valve, and protects the heat exchanger from freeze damage during Arcadia's cold snaps. We also check the thermostatic mixing valve and insulate exposed lines. Book this before the first hard freeze, usually late November.
View service 04Tankless Water Heater Filter Replacement
Clogged filters cause low flow and unit keeps shutting off faults. We replace the inlet water filter, clean the screen, and test flow rate at the fixture. On Navien and Rinnai units this alone restores hot water pressure in about 30 minutes.
View service 05Gas & Electrical Connection Audits
An audit verifies gas line sizing, checks for leaks with a gas leak detector, and confirms the electrical connection meets NEC and ANSI Z21.10.3 requirements. We tighten grounds, test the igniter circuit with a multimeter, and flag anything that fails code before it becomes a hazard.
View service 06Igniter & Burner Repair
Igniter failure shows up as clicking with no ignition or repeated shutdowns. We pull the burner, clean carbon buildup, test the igniter with a multimeter, and replace failed components. Most igniter and burner repairs finish in under two hours.
View service 07Gas Valve Replacement
A failing gas valve causes weak flame, error codes, or no heat at all. We isolate the gas, replace the valve, then set manifold pressure with a manometer and confirm combustion with an analyzer. Gas work is performed by our state-licensed plumbing contractor under California Plumbing Code.
View service 08Heating Element Replacement
On electric tankless units, a burned heating element means lukewarm water or none. We test resistance with a multimeter, replace the element, and inspect O-rings and gaskets for leaks. Same-day parts on Bosch, Eccotemp and Rheem electric models.
View service 09Heat Exchanger Repair & Replacement
Scale buildup and freeze damage are the two killers of a heat exchanger in Arcadia. We descale with a pump and flush kit when the metal is sound, and replace the exchanger when it is cracked or leaking. This is the biggest tankless repair we do, and we quote it before we start.
