What we run into in Cedar Park
- 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.

When people phone about tankless water heater repair in Cedar Park, TX, it is nearly always one of these problems. Each has a short list of causes.
Code 11, E003 or 111
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
Venting codes mean the unit can't breathe: a blocked termination, a nest, snow or a vent run that's too long.
Shuts off mid-shower
Flow drops below what the unit needs to keep firing: a clogged filter, aerator or shower cartridge, or a sensor misreading.
Not as hot as it used to be
Scale on the heat exchanger, a weak gas supply or a thermistor reading wrong.
LC code on a Rinnai
The unit is reporting scale buildup. It needs a descale, and soon.
