What we run into in Southlake
- 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.

These are the faults behind most calls for tankless water heater repair in Southlake, TX. The display usually points at one of them.
Unit won't light
A unit that clicks without lighting has an ignition, gas or venting fault, and each is checked in turn.
Drip from the cabinet
Water below a tankless can be a valve, a fitting, condensate or a failed exchanger. The source decides the cost.
Venting fault
An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.
LC code on a Rinnai
The unit is reporting scale buildup. It needs a descale, and soon.
Frozen after a cold night
Lines feeding the unit froze, or freeze protection lost power.

Fix It or Retire It? Deciding in Southlake

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.
