We provide a detailed estimate after diagnosing the specific problem.
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.
Yes, regular maintenance, particularly annual descaling due to hard water in Texas, is crucial for tankless water heaters. It prevents mineral buildup, maintains efficiency, and extends the lifespan of the unit, often preventing costly repairs.
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.
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 warrant a professional inspection.
Minor tankless water heater repairs, such as replacing a sensor or igniter, typically do not require a permit in San Antonio. However, major component replacements, alterations to the gas or water lines, or replacing the entire unit may require a plumbing permit to ensure code compliance.
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, common in Texas.
While some basic troubleshooting, like checking the power supply or gas valve, can be done, most tankless water heater repairs require specialized tools and knowledge. Attempting DIY repairs on gas or electrical components can be dangerous and void your warranty. It's always best to call a professional.
