Tankless Water Heater Tune-Up


Expert maintenance will help protect your tankless water heater investment. Relax and enjoy the endless hot water, our factory trained technicians will keep it running smoothly,

While this basic tune-up is recommended annually, other periodic maintenance may be needed depending on your use and water. During your maintenance we inspect the heat exchanger and lime scale buildup and may recommend additional cleaning or flushing as needed. There are extra charges for these services, and we won’t recommend them unless you actually need it.
