Professional Boiler Repair & Service Services

Boilers provide hydronic (hot water or steam) heating — circulating heated water through radiators, baseboard heaters, or radiant floor loops to warm your home. They are especially common in older homes and in northern climates where their consistent, even heat is valued. When a boiler malfunctions, the entire heating system is affected.

Common boiler problems include no heat (caused by a failed igniter, thermocouple, or gas valve), loss of pressure (indicating a leak in the system or a failed expansion tank), unusual noises (kettling from scale buildup, banging from air in the system, or gurgling from low water levels), leaks from the boiler body or circulator pump, and frequent cycling (the boiler turning on and off repeatedly).

Boiler maintenance is essential for safe, efficient operation. Annual service typically includes cleaning the heat exchanger surfaces, checking the combustion and flue for proper venting, testing safety controls (pressure relief valve, low-water cutoff, backflow preventer), inspecting the circulator pump and expansion tank, and verifying proper gas pressure and combustion efficiency. A well-maintained boiler can last 15 to 30 years.

When replacement is needed, modern high-efficiency condensing boilers achieve 95%+ AFUE (Annual Fuel Utilization Efficiency) compared to 80% or less for older standard boilers — a significant reduction in heating costs. Combi boilers (combination boilers) provide both space heating and domestic hot water from a single unit, eliminating the need for a separate water heater.
