Tankless Repair vs Replacement Cost in Hopkinsville, KY
Descaling service usually costs $175 to $350, and sensor or igniter repairs run $250 to $600. Heat exchanger replacement can cost $800 to $1,500 or more unless covered by warranty. A new tankless unit installed usually ranges from $3,000 to $5,500. We compare these costs against the age and condition of your unit.

Tankless Descaling and Flushing in Hopkinsville
Hard water leaves calcium and magnesium scale inside the heat exchanger, limiting 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 a smart move for most homes on hard water.
Ignition Failure Repair in Hopkinsville, KY
If your tankless unit will not fire, the cause may be a dirty flame rod, a bad igniter, low gas pressure or a blocked intake. We test each component and measure gas pressure at the inlet. Undersized gas lines are a frequent hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights every time.
Gas Tankless Water Heater Repair in Hopkinsville
Gas tankless water heaters require correct gas pressure and proper ventilation for safe operation. Issues can range from gas valve malfunctions to carbon monoxide sensor errors. Our certified technicians in Hopkinsville perform thorough diagnostics on gas lines, igniters and exhaust systems, so your unit is both functional and safe.
No Hot Water Tankless Repair in Hopkinsville
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 Hopkinsville will thoroughly diagnose the root cause, whether it is a faulty igniter, a pressure sensor malfunction or mineral buildup. We carry common replacement parts for fast fixes, restoring your continuous hot water supply efficiently. We also check for proper venting, which is essential for the safe operation of your unit.
Flow Sensor and Thermistor Repair in Hopkinsville
Tankless heaters use flow sensors to start and thermistors to regulate temperature. A dirty inlet filter or failed sensor causes no hot water, fluctuating temperature or the unit turning off mid-shower. We clean filters, test sensor readings and replace faulty parts. Temperature becomes steady again once readings are accurate.
Pilot Light & Ignition Repair in Hopkinsville, KY
For gas-fired tankless water heaters, a faulty ignition system can completely stop hot water production. Our team in Hopkinsville, KY diagnoses issues with igniters, flame sensors and gas valves. We confirm proper gas pressure and ventilation are maintained for safe and efficient operation. Timely repair of these components prevents hazardous gas problems and restores your unit's ability to heat water on demand.

Tankless Water Heater Descaling Service in Hopkinsville
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, cutting efficiency and eventually causing breakdowns. Water softeners are a popular upgrade in Kentucky homes, protecting tank water heaters, faucets, and appliances from mineral buildup. Our descaling service in Hopkinsville involves flushing the unit with a dedicated cleaning solution to dissolve these mineral deposits. This preventative maintenance and repair step is key for extending the lifespan of your tankless heater and keeping it at peak performance.
