Tankless Units in Hillsborough Homes
Many Hillsborough homes are brick ranches where the tankless went onto an outside wall or into the garage. Occasional hard freezes and gas supply sizing cause most of our calls.
What we run into in Hillsborough
- 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 Hillsborough, NC 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
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.
LC code on a Rinnai
The unit is reporting scale buildup. It needs a descale, and soon.
Display is blank
No power at the outlet, a blown fuse or a failed control board.
Noisy or whistling
Scale, a struggling fan or a gas regulator issue, each of which shows up on testing.
Can't tell which one you have? Read us the display and describe the water, and the likely fault comes back on the call.

Call (380) 273-8196How much does tankless water heater repair in Hillsborough, NC cost?
Most repairs cost an estimated $150 to $800, depending on the part. Descaling alone is estimated at $150 to $350, and a heat exchanger at $1,000 to $2,500. Freeze repairs depend on what split, and are priced once the damage is seen.
How often should a tankless water heater be flushed?
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.
Why does my tankless water heater go hot then cold?
A brief cold slug after a tap reopens is the unit restarting. Swings during one shower usually mean flow below the unit's minimum, scale on the exchanger, or a failing flow sensor.
Why is my tankless water heater not turning on?
First confirm power and gas. If both are there, the usual causes are low flow, a dirty inlet filter, a bad flow sensor or an ignition fault.
