Our Boiler Repair Process

Straightforward Repair, No Surprises

When you call, we get the basic details about what’s happening with your boiler and schedule a time that works for you. For true emergencies, we prioritize getting someone out as quickly as possible.

Our technician arrives with the diagnostic tools and common parts needed for most boiler repairs. They’ll explain what they’re checking, run through the diagnosis process, and identify exactly what’s causing the problem.

Before any work starts, you’ll get a clear explanation of what needs to be done and what it costs. No hidden fees, no surprise charges after the work’s finished. Once you approve, we complete the repair and test the system to make sure everything’s working properly before we leave.

For true heating emergencies, especially during cold weather, we prioritize same-day service when possible. We understand that a broken boiler in winter isn’t something you can wait days to fix. When you call, we’ll give you a realistic timeframe based on our current schedule and the urgency of your situation. Emergency calls get moved to the front of the line, and we’ll work to get your heat restored as quickly as we safely can.
In this area, we frequently deal with issues related to older boiler systems and the freeze-thaw cycles common in Massachusetts winters. Circulator pump failures, thermostat malfunctions, and pressure-related problems are common. We also see a lot of maintenance-related issues like dirty or clogged components that cause the system to work harder than it should. Many problems we encounter could have been prevented with regular servicing, which is why we recommend annual maintenance visits.
Yes, absolutely. After diagnosing the problem, we’ll explain exactly what needs to be done and provide clear pricing before any repair work begins. You’ll know what the job costs upfront, not after we’re finished. This includes labor, parts, and any additional services needed to complete the repair properly. We don’t believe in surprise charges or hidden fees, especially when you’re already dealing with the stress of a heating system breakdown.
We service and repair most boiler types and brands commonly found in Norfolk County homes, including gas boilers, oil boilers, and combination heating systems. Our technicians carry diagnostic equipment and common replacement parts for major manufacturers. If your boiler requires a specialized part, we’ll source it quickly and keep you informed about timing. In rare cases where a boiler is beyond economical repair, we’ll be honest about that and discuss replacement options.
First, check your thermostat settings and make sure the power switch for the boiler is on. Look for any obvious error codes or warning lights on the unit itself. If everything appears normal but you’re still not getting heat, turn off the boiler and call us. Don’t attempt to repair it yourself, especially if you smell gas or suspect any safety issues. We’ll walk you through any immediate safety steps over the phone and get a technician scheduled as quickly as possible.
Regular annual maintenance is the most effective way to prevent unexpected breakdowns and extend your boiler’s lifespan. During maintenance visits, we clean components, check safety systems, test efficiency, and identify small issues before they become major problems. Our Dempsey Comfort Club members get priority scheduling for these maintenance visits plus benefits like discounted repairs. Simple things like changing filters regularly and keeping the area around your boiler clean also help, but professional annual servicing catches problems most homeowners would miss.
