Tankless Repair in Baytown
A tankless water heater tells you when something is wrong. It shows an error code, shuts down or sends water that goes hot and cold.
We read the code, test the unit and repair what failed. We are an authorized Noritz dealer, and we repair the other major brands too.

Common Tankless Repairs
Scale Buildup
Minerals coat the heat exchanger and choke the flow. A descaling flush clears it.
Ignition and Flame Problems
A dirty flame sensor or a failed igniter keeps the burner from lighting.
Gas Supply
A tankless unit needs more gas than a tank. An undersized gas line causes shutdowns under demand.
Venting and Air
A blocked vent or air intake trips a safety shutoff. We clear it and check the vent run.
Yearly Tankless Maintenance
Most tankless breakdowns start with scale. A yearly flush removes it before it damages the heat exchanger.
During the visit we flush the unit, clean the inlet filter and check for stored error codes.
