Tankless Units in Mount Holly Homes
In Mount Holly, units are often retrofits on older homes. Ignition faults and frozen lines after a cold snap are the common repairs.
What we run into in Mount Holly
- 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 Mount Holly, NC. 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.
Error code keeps coming back
A reset only clears the symptom. Repeated ignition or exhaust codes need a visit.
Hot, then cold, then hot
A short cold burst after the tap reopens is normal start-up. Swings during one shower point to low flow, scale or a failing flow sensor.
Not as hot as it used to be
Scale on the heat exchanger, a weak gas supply or a thermistor reading wrong.
Can't tell which one you have? Read us the display and describe the water, and the likely fault comes back on the call.

Once a year for most homes, and twice a year on very hard water. Soft-water homes can stretch it, but never skip it for years.
