Tankless Units in Simpsonville Homes
Many Simpsonville 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 Simpsonville
- 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 Simpsonville, SC, it is nearly always one of these problems. Each has a short list of causes.
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.
Display is blank
No power at the outlet, a blown fuse or a failed control board.
Frozen after a cold night
Lines feeding the unit froze, or freeze protection lost power.
Error code keeps coming back
A reset only clears the symptom. Repeated ignition or exhaust codes need a visit.

Call (380) 273-8196How much does tankless water heater repair in Simpsonville, SC 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.
Why does my tankless water heater go hot then cold?
A second or two of cold after the tap reopens is normal start-up. If the water swings while it runs, look at low flow, scale or the flow sensor.
Why is my tankless water heater not turning on?
Check for power at the outlet and that the gas valve is open. Beyond that it is usually low flow, a clogged inlet filter, a failed flow sensor or an ignition fault.
What is the most common problem with tankless water heaters?
Scale in the heat exchanger, followed by ignition faults and flow sensor or filter problems. All three usually show up as a code or as water that won't stay hot.
