Tankless Units in Greenwood Homes
Greenwood winters are mild but not frost-free, and an outdoor unit without power on a freezing night can crack a fitting. Flow sensors and igniters are the other usual parts.
What we run into in Greenwood
- Freeze damage. A hard freeze can split the pipes feeding a unit. Its built-in freeze protection only works while the unit still has power and gas.
- Retrofit installs. Retrofits are common in this housing stock. When a unit throws flame codes only while the furnace or dryer runs, the gas supply is the first suspect.

Tankless Water Heater Repair in Greenwood, SC: FAQs
Question not covered here?
Call and ask. Someone who repairs tankless units answers, and the phone quote is free.
Call (380) 273-8196How much does tankless water heater repair in Greenwood, 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.
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.
Can a tankless water heater be repaired?
Yes, in most cases. Igniters, flame rods, flow sensors, thermistors, fans, gas valves and boards are all replaceable, and scale can be descaled. A leaking heat exchanger on an old unit is the main exception.
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.
