Our certified technicians in Fairmont perform thorough diagnostics on gas lines, igniters and exhaust systems, so your unit is both functional and safe.
Tankless Descaling and Flushing in Fairmont
Hard water leaves calcium and magnesium scale inside the heat exchanger, limiting flow and causing overheating. Many units warn of this with scale codes, such as the LC code on Rinnai models. We connect a circulation pump to the service valves and run a descaling solution through the exchanger. Annual descaling is a smart move for most homes on hard water.

Frequently Asked Questions About Tankless Water Heater Repair in Fairmont
The cost of tankless water heater repair in Fairmont varies a lot depending on the issue, ranging from $150 for minor fixes like sensor replacement to $600 or more for complex repairs involving heat exchanger descaling or major component replacements. We provide a detailed estimate after identifying the specific problem.
Minor tankless water heater repairs, such as replacing a sensor or igniter, typically do not require a permit in Fairmont. Major component replacements, changes to the gas or water lines, or replacing the entire unit may require a plumbing permit to ensure code compliance.
Error codes can be caused by a variety of issues, such as low water flow, gas supply problems, ignition failures, exhaust blockages or faulty temperature sensors. Each code corresponds to a specific system malfunction.
Regular maintenance, particularly annual descaling, is important for tankless water heaters in homes with hard water. It prevents mineral buildup, maintains efficiency, extends the lifespan of the unit and helps avoid costly repairs by catching small issues before they grow.
We stand behind our tankless water heater repairs with a comprehensive warranty on both parts and labor. The exact warranty period will be discussed with you before any work begins, providing you peace of mind.
Some homeowners do with a kit if service valves are installed. Diagnosing error codes and replacing sensors, igniters or gas components should be left to a pro.
Common signs include inconsistent hot water, a sudden loss of hot water, strange noises like banging or popping, a rotten egg smell or error codes displayed on the unit. Any of these symptoms call for a professional inspection.
Regular professional maintenance, including descaling and checking all connections, is the best prevention. Installing a whole-home water softener can also significantly reduce mineral buildup in areas with very hard water.
