We prioritize emergency boiler repairs, especially during cold weather when your family’s comfort and safety are at risk. Most emergency calls in Randolph and Norfolk County get same-day service, and we often arrive within a few hours of your call. We understand that a broken boiler can’t wait, particularly during Massachusetts winters when temperatures drop below freezing. Our technicians carry common repair parts and diagnostic equipment to resolve many issues on the first visit, getting your heat restored as quickly as possible.
The most frequent boiler issues we repair include faulty pumps that stop circulating hot water, thermostat problems that prevent proper temperature control, and pressure issues that cause the system to shut down for safety. We also see a lot of problems with older boilers where components like gas valves or heat exchangers start failing after years of use. Sediment buildup and mineral deposits are common in our area due to local water conditions, which can reduce efficiency and cause overheating. Regular maintenance catches most of these problems before they turn into expensive emergency repairs.
This depends on your boiler’s age, the repair cost, and how often you’re calling for service. If your boiler is over 15 years old and needs frequent repairs, replacement usually makes more financial sense in the long run. However, if you have a newer system with a specific component failure, repair is typically the better choice. We’ll give you honest guidance based on your situation – sometimes a $300 repair on a well-maintained 10-year-old boiler is smarter than spending thousands on replacement. We look at your system’s overall condition and help you make the decision that works best for your budget and comfort needs.
Yes, our technicians work on all major boiler types including gas, oil, and electric systems. We service both older cast iron boilers common in Norfolk County homes and newer high-efficiency condensing units. Whether you have a traditional boiler with radiators or a modern system with baseboard heating, we have the experience and tools to diagnose and repair it properly. We also handle combination boilers that provide both heating and hot water, as well as steam systems that are still found in some older Randolph area homes.
Our boiler maintenance includes a complete system inspection, cleaning of key components, and testing of all safety controls to ensure everything operates correctly. We check and adjust the burner, inspect the heat exchanger for cracks or corrosion, and test the pressure relief valve and other safety devices. We also examine the venting system, clean or replace filters, and check for proper water levels and pressure. This preventive approach helps your boiler run more efficiently, extends its lifespan, and catches small problems before they become expensive repairs. Dempsey Comfort Club members get priority scheduling for maintenance visits.
A quality boiler repair addresses the root cause of the problem, not just the immediate symptoms. We use proper diagnostic procedures to identify why the failure occurred and replace components with quality parts designed for your specific boiler model. You’ll know the repair is solid when your system runs quietly, heats evenly throughout your home, and maintains consistent temperatures without cycling on and off frequently. We stand behind our work and explain what we’ve done so you understand your system better. If you’re still having issues after our repair, we’ll come back to make it right.
