Gas Tankless Water Heater Repair in Poughkeepsie
Gas tankless water heaters require precise gas pressure and proper ventilation for safe operation. Issues can range from gas valve malfunctions to carbon monoxide sensor errors. Our certified technicians in Poughkeepsie perform thorough diagnostics on gas lines, igniters and exhaust systems, so your unit is both functional and safe.

Flow Sensor and Thermistor Repair in Poughkeepsie
Tankless heaters use flow sensors to start and thermistors to regulate temperature.

Temperature becomes steady again once readings are correct.
Tankless Water Heater Descaling Service in Poughkeepsie
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, cutting efficiency and eventually causing breakdowns. Water hardness in New York varies a lot, with many surface water supplies running soft and groundwater in some areas running hard. Our descaling service in Poughkeepsie involves flushing the unit with a specialized cleaning solution to dissolve these mineral deposits. This preventative maintenance and repair step is crucial for extending the lifespan of your tankless heater and keeping it at peak performance.
Tankless Descaling and Flushing in Poughkeepsie
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.
