Pilot Light and Ignition Repair in Elizabethtown, KY
For gas-fired tankless water heaters, a malfunctioning ignition system can completely stop hot water production. Our team in Elizabethtown, KY diagnoses issues with igniters, flame sensors and gas valves. We ensure proper gas pressure and ventilation are maintained for safe and efficient operation. Timely repair of these components prevents dangerous gas problems and restores your unit's ability to heat water on demand.

Condensing Tankless Repair in Elizabethtown, KY
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 confirm proper drainage. PVC venting is also inspected for slope and sagging.
Rinnai Tankless Water Heater Repair in Elizabethtown, KY
Rinnai is a popular tankless brand, and its units can face challenges such as scaling from hard water or issues with their flame rod. Our technicians in Elizabethtown, KY are adept at Rinnai tankless water heater repair, focusing on descaling services, fan motor replacements and resolving issues with gas valve assemblies. We ensure your Rinnai system continues to provide reliable, on-demand hot water, following manufacturer specifications.
Emergency Tankless Repair in Elizabethtown
A tankless unit that leaks internally or shows a fault you cannot clear needs quick attention. We prioritize no-hot-water calls and arrive with common sensors, igniters and filters. If a major component like a heat exchanger has failed, we check warranty coverage and order the part. We can often restore partial operation in the meanwhile.
Tankless Descaling and Flushing in Elizabethtown
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 wise for most homes on hard water.
Ignition Failure Repair in Elizabethtown, 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 common hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights every time.
No Hot Water Tankless Repair in Elizabethtown
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 Elizabethtown will carefully diagnose the root cause, whether it is a faulty igniter, a pressure sensor fault 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.

Recirculation Pump Repair in Elizabethtown
Many tankless systems use internal or external recirculation to deliver hot water faster. 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 daily routine. A properly tuned system saves both water and gas.
