Complete Boiler Repair Coverage

Every boiler repair includes thorough system testing to catch other potential issues before they leave you cold again. You’re not just getting a quick fix—you’re getting a thorough look at your heating system’s health.

Canton’s older homes often have boiler systems that need specific expertise. Many contractors guess their way through repairs on older equipment. Our technicians have the experience to work on all types of boilers, from newer high-efficiency units to older cast iron systems that have been heating homes for decades.

Emergency repairs get priority response because we understand that losing heat in Massachusetts winter isn’t just uncomfortable—it’s potentially dangerous. Regular maintenance and tune-ups are also available to keep your system running smoothly all season long.

Emergency boiler repairs typically get same-day or next-day response, depending on when you call and current demand. During extreme cold snaps, response times may extend slightly, but heating emergencies always get priority scheduling. Our goal is to get your heat restored as quickly as possible, especially when temperatures drop below freezing. If you’re a Dempsey Comfort Club member, you get priority scheduling over non-members for both emergency and routine service calls.
Older Canton homes frequently experience issues with circulator pumps failing, thermostats malfunctioning, and sediment buildup in the system causing poor heat distribution. Pilot light problems are common in older gas boilers, while oil boilers often need burner cleaning and fuel line maintenance. Many older boilers also suffer from expansion tank problems that cause pressure issues throughout the heating system. Radiator valve issues and air trapped in the system also cause uneven heating.
If your boiler is over 15-20 years old and needs major component replacement, replacement often makes more financial sense than expensive repairs. However, many older boilers can run efficiently for years with proper maintenance and minor repairs. The decision depends on the specific repair needed, your boiler’s overall condition, and your energy costs. A thorough inspection can determine whether repair or replacement gives you better long-term value for your specific situation.
Boiler repair costs vary significantly based on the specific problem and parts needed. Minor issues like thermostat replacement or bleeding radiators cost much less than major component failures like heat exchanger problems. Rather than guessing at costs over the phone, our technicians provide upfront estimates after diagnosing the actual problem. This makes sure you know exactly what you’re paying for before any work begins, with no surprise charges added later.
We service all major boiler brands and fuel types, including gas, oil, and electric systems. This includes both newer high-efficiency condensing boilers and older cast iron boilers common in Canton’s historic homes. Our technicians carry common parts for most major brands and can source specialized components for older or less common systems. Whether you have a Weil-McLain, Burnham, Crown, or other brand, we have the experience to diagnose and repair it properly.
Annual boiler maintenance before the heating season starts prevents most emergency breakdowns. This includes cleaning the system, checking all safety controls, testing the thermostat, and inspecting vents and flues. Keep the area around your boiler clear and check that nothing is blocking air intake or exhaust vents. If you notice unusual noises, uneven heating, or higher energy bills, address these issues promptly rather than waiting for complete system failure during the coldest weather.
