Ignition Failure Repair in Boston, 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.

Our technicians in Boston will carefully diagnose the root cause, whether it is a faulty igniter, a pressure sensor malfunction or mineral buildup.

Tankless Water Heater Descaling Service in Boston
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 in Massachusetts vary widely, so testing for acidity, iron and other minerals around Boston is the right start before adding treatment. Our descaling service in Boston involves flushing the unit with a dedicated cleaning solution to dissolve these mineral deposits. This preventative maintenance and repair step is crucial for extending the lifespan of your tankless heater and keeping it at peak performance.

We are available to troubleshoot issues like major leaks, complete system shutdowns or persistent error codes that prevent any hot water production.

Tankless Repair vs Replacement Cost in Boston, 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 usually ranges from $3,000 to $5,500. We compare these costs against the age and condition of your unit.
Flow Sensor and Thermistor Repair in Boston
Tankless heaters use flow sensors to start and thermistors to regulate temperature.

Temperature becomes steady again once readings are accurate.
