Heat Exchanger Descaling in Jeffersonville
The heat exchanger in a tankless heater is a coil of small tubes that water races through while the burner fires. Hard water drops calcium and magnesium on those hot surfaces, narrowing the passages over time. We connect a submersible pump and hoses to the service valves and circulate descaling solution for 45 to 60 minutes. Then we flush with fresh water to rinse the system thoroughly. Restored flow means more stable temperatures and fewer shutdowns.
Isolation Valve Kit Installation in Jeffersonville, IN
Some tankless heaters were installed without service valves, which makes proper flushing very difficult. We install a set of isolation valves with purge ports on the hot and cold lines so future maintenance takes minutes. The kit also lets you shut off water to the heater without closing the main. It is a one-time upgrade that pays for itself in simpler service.
Navien Tankless Heater Tune-Ups in Jeffersonville
Navien tankless water heaters often feature condensing technology, making them highly efficient but also requiring particular maintenance.

We also ensure a proper air-fuel mixture and calibrate sensors for peak efficiency in Jeffersonville homes.

Commercial Tankless Rack Maintenance in Jeffersonville
Restaurants, salons and multi-family buildings often run several tankless units linked together. Commercial racks see heavy use and scale faster than home units.
