We stand behind our tankless water heater repairs with a comprehensive warranty on both parts and labor. The specific 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.
Minor repairs typically do not require a permit. If the repair involves significant changes to the gas or water lines, or if the unit itself is being replaced, a permit from the Concord building department may be necessary. We handle all necessary permitting for you.

Yes, our technicians are trained and experienced in repairing all major tankless water heater brands, including Rinnai, Navien, Noritz, Rheem, Bosch, A.O. Smith and more. We carry a wide selection of common parts for various models.
Fluctuating temperatures can come from low flow rates, a dirty inlet filter, a failing flow sensor or scale on the heat exchanger. Crossed hot and cold lines at a fixture can cause it too.
