Tankless Units in Lewisville Homes
Most Lewisville homes are brick houses where the tankless sits in the garage or on an outside wall. The February 2021 freeze showed how fast exposed lines can split here.
What we run into in Lewisville
- Freeze damage. Cold snaps do damage here when the power drops overnight. A frozen line or a cracked fitting under the unit is a repair we see after every deep freeze.
- Retrofit installs. In older homes converted to tankless, the original gas piping is not always big enough. Pressure gets measured with the burner at full fire before parts are blamed.

Most requests for tankless water heater repair in Lewisville, TX start with one of the symptoms below, and most end with a single part or a descale.
Unit won't light
No ignition usually means gas pressure, a worn igniter, a dirty flame rod or a blocked vent. Each is tested.
Water under the unit
Drips come from service valves, fittings, the relief valve, the condensate line or the heat exchanger itself.
Code 10 or E110
An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.
Not as hot as it used to be
Scale on the heat exchanger, a weak gas supply or a thermistor reading wrong.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.
Display is blank
No power at the outlet, a blown fuse or a failed control board.

Fix It or Retire It? Deciding in Lewisville
Gas tankless units commonly last 20 years or more with flushing, so a single failed part rarely means a new heater. A failed exchanger outside its warranty, on a unit past 15 years, is where replacement starts to win.
Read the model and serial off the label and call (380) 273-8196. The age and the fault together usually settle repair versus replace on the phone.
