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 range of common parts for various models.
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.
Regular professional maintenance, including descaling and checking all connections, is the best prevention. Installing a whole-home water softener can also greatly reduce mineral buildup in areas with very hard water.
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 also be the cause.
Common causes of failure include mineral buildup from hard water, ignition problems, faulty flow sensors, clogged air filters, exhaust venting issues and electrical component failures. Regular maintenance, including descaling, can prevent many of these problems.
