Frequently Asked Questions About Water Heater Repair in Custer, SD

Tankless water heaters are an excellent upgrade if you want endless hot water and lower energy bills. They heat water only when you need it and take up much less space, making them a popular choice for homes in Custer, SD.
Absolutely. Our technicians are trained to repair all major brands including A.O. Smith, Rheem, Bradford White, State, Rinnai, and Navien. Whether you have a standard tank or a high-efficiency tankless system, we carry the right parts. Contact (877) 415-0636 for help.
Hard water is very tough on tankless heaters because the intense heat causes calcium to rapidly build up inside the narrow heat exchanger. You must have your tankless unit descaled annually to prevent irreversible damage.
Yes. Sediment creates a thick layer of insulation between the burner and the water. The burner has to run longer and hotter to heat the water, which overheats and weakens the steel tank bottom, eventually causing it to fracture.
If your home is on a closed plumbing system (such as having a pressure reducing valve), thermal expansion can cause dangerous pressure spikes when water heats up. An expansion tank absorbs this pressure and protects your water heater.
