Complete Boiler Servicing Solutions

Everything Your Boiler Needs to Run Right

Your boiler repair includes complete system diagnostics, not just a quick patch job. We check all components, test safety controls, and identify potential issues before they become expensive problems.

Every repair comes with clear documentation of what we found and what we fixed. You’ll understand your system better and know what to watch for going forward.

We also offer ongoing maintenance through our Dempsey Comfort Club to keep your boiler running efficiently between service calls. Regular maintenance prevents most emergency breakdowns and extends your system’s life significantly.

How quickly can you respond to a boiler emergency in Fairhaven?

We prioritize emergency heating calls, especially during cold weather when your family’s comfort and safety are at risk. Response times vary based on current demand and weather conditions, but we work to reach you as quickly as possible. During peak winter months, we recommend calling as early as possible when you notice heating issues rather than waiting for a complete breakdown. Our goal is always same-day service for emergency situations.

Should I repair my old boiler or replace it entirely?

This depends on your boiler’s age, condition, and repair history. Generally, if your boiler is over 15 years old and needs frequent repairs, replacement often makes more financial sense. We’ll assess your specific situation honestly—sometimes a repair buys you several more years of reliable service, while other times the repair costs approach what you’d spend on a new, more efficient system. We’ll walk through the numbers with you so you can make an informed decision.

What causes most boiler breakdowns during winter?

The most common winter boiler problems we see include frozen pipes, faulty thermostats, pump failures, and pressure issues. Many of these stem from a lack of regular maintenance—things like dirty filters, mineral buildup, or worn components that finally fail under heavy use. Cold weather puts extra stress on aging systems, which is why problems often surface during the first severe snap of the season.

Do you provide estimates before starting boiler repair work?

Absolutely. We believe in complete transparency about repair costs before any work begins. After diagnosing the problem, we’ll explain what’s wrong, what needs to be fixed, and provide a clear estimate for the work. You’ll never face surprise charges or hidden fees. If we discover additional issues during the repair, we’ll discuss those with you before proceeding with any extra work.

Can you service all types of boilers?

Yes, our technicians work on all major boiler brands and fuel types—gas, oil, and electric systems. We’ve serviced everything from newer high-efficiency condensing boilers to older cast iron units that have been running for decades. Each type has its specific requirements and common issues, and our experience with Fairhaven’s diverse housing stock means we’re familiar with most systems you’ll find in local homes.

How can I prevent future boiler problems?

Regular annual maintenance is the best prevention. This includes cleaning, inspection of all components, testing safety controls, and addressing small issues before they become major problems. Simple things like changing filters, keeping the area around your boiler clear, and monitoring for unusual noises or performance changes also help. Our Dempsey Comfort Club provides scheduled maintenance that catches most problems early, saving you money and preventing emergency breakdowns.
