Condensing Tankless Repair in Quincy, MA
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.

Recirculation Pump Repair in Quincy
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.
Flow Sensor and Thermistor Repair in Quincy
Tankless heaters rely on 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 failed parts. Temperature becomes steady again once readings are correct.
Tankless Repair vs Replacement Cost in Quincy, MA
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.
Ignition Failure Repair in Quincy, MA
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 & Ignition Repair in Quincy, MA
For gas-fired tankless water heaters, a malfunctioning ignition system can completely stop hot water production. Our team in Quincy, MA diagnoses issues with igniters, flame sensors and gas valves.
