Same-Day Boiler Repair in Portland and Southern Maine

We dispatch quickly to boiler repair calls across Cumberland and York Counties — Portland, South Portland, Scarborough, Cape Elizabeth, Gorham, Westbrook, Falmouth, Windham, Saco, Biddeford, Kennebunk, and surrounding towns. For no-heat emergencies in winter, we prioritize response and aim to be on-site within two hours of your call. We service gas and oil boilers from all major manufacturers.

Common Boiler Problems We Repair

The most frequent boiler repair calls we receive include: no heat or insufficient heat, pilot or ignition failure, pressure relief valve issues, circulator pump failure, zone valve problems, thermostatic radiator valve failures, kettling or banging sounds (limescale buildup), low water pressure, expansion tank failure, gas valve problems, and draft inducer failures. We diagnose the root cause — not just the symptom — and repair it correctly the first time.

Oil Boiler Repair Specialists

Oil-fired boilers require specialized knowledge — particularly around combustion analysis, fuel delivery systems, and burner adjustment. Our technicians are trained and experienced on oil boilers and carry parts for most major brands. We also perform oil boiler tune-ups and annual cleanings to prevent failures before they happen.
