No Hot Water Tankless Repair in Nitro
When your tankless unit fails to produce hot water, it is often due to issues with the ignition, gas supply or a clogged heat exchanger. Our technicians in Nitro will carefully diagnose the root cause, whether it is a faulty igniter, a pressure sensor malfunction or mineral buildup.

Tankless Descaling and Flushing in Nitro
Hard water leaves calcium and magnesium scale inside the heat exchanger, restricting flow and causing overheating. Many units warn of this with scale codes, such as the LC code on Rinnai models. We connect a circulation pump to the service valves and run a descaling solution through the exchanger. Annual descaling is wise for most homes on hard water.
Condensing Tankless Repair in Nitro, WV
Condensing tankless heaters, such as many Navien models, extract extra heat from exhaust and produce condensate. Clogged condensate traps, failed neutralizers and blocked drains can shut the unit down. We clean the trap, replace the neutralizer media and verify proper drainage. PVC venting is also checked for slope and sagging.
