Ignition Failure Repair in Summerville, SC
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.
Pilot Light and Ignition Repair in Summerville, SC
For gas-fired tankless water heaters, a faulty ignition system can completely stop hot water production. Our team in Summerville, SC 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 hazardous gas problems and restores your unit's ability to heat water on demand.
Tankless Repair vs Replacement Cost in Summerville, SC
Descaling service typically 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.
Tankless Descaling and Flushing in Summerville
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 a smart move for most homes on hard water.
Rinnai Tankless Water Heater Repair in Summerville, SC
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 Summerville, SC are skilled at Rinnai tankless water heater repair, focusing on descaling services, fan motor replacements and resolving issues with gas valve assemblies. We make sure your Rinnai system continues to provide reliable, on-demand hot water, following manufacturer specifications.
Condensing Tankless Repair in Summerville, SC
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 inspected for slope and sagging.
Recirculation Pump Repair in Summerville
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 routine. A properly tuned system saves both water and gas.
Noritz Tankless Water Heater Repair in Summerville, SC
Noritz tankless heaters are known for their robust design, but can sometimes face issues such as flow sensor faults or venting problems. We provide specialized repair services for Noritz units in Summerville, SC, ensuring proper combustion, water flow and exhaust, which are essential for safe and efficient operation.
