Ignition Failure Repair in Overland Park, KS
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 reliably.
Tankless Repair vs Replacement Cost in Overland Park, KS
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 typically ranges from $3,000 to $5,500. We compare these costs against the age and condition of your unit.
Gas Tankless Water Heater Repair in Overland Park
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 licensed technicians in Overland Park perform thorough diagnostics on gas lines, igniters and exhaust systems, so your unit is both functional and safe.
Flow Sensor and Thermistor Repair in Overland Park
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.
Recirculation Pump Repair in Overland Park
Many tankless systems use internal or external recirculation to deliver hot water more quickly. Pump failures, check valve problems or wrong schedule settings can cause long waits or lukewarm water. We test the pump, check valves and controls and set the schedule to match your routine. A properly tuned system saves both water and gas.

Tankless Water Heater Descaling Service in Overland Park
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, cutting efficiency and eventually causing breakdowns. Private wells serve many rural homes, and minerals, sediment, and nitrate levels make periodic well testing a good habit. Our descaling service in Overland Park 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.

Fluctuating temperatures can come from low flow rates, a dirty inlet filter, a failing flow sensor or scale on the heat exchanger. Crossed hot and cold lines at a fixture can cause it too.
With regular descaling, tankless heaters often last 15 to 20 years. Without maintenance in hard water, problems can start within a few years.
Yes, regular maintenance, particularly annual descaling where water is hard, is crucial for tankless water heaters. It prevents mineral buildup, maintains efficiency and extends the lifespan of the unit, often heading off costly repairs.
