How quickly can you respond to a furnace emergency in Medfield?

Response time depends on the current service load and weather conditions, but we prioritize heating emergencies, especially during cold weather. When you call, we’ll give you a realistic timeframe and keep you updated if anything changes. During extreme weather events when everyone’s furnace seems to break at once, we work extended hours to get to as many customers as possible. We understand that a broken furnace in January isn’t something you can wait days to fix.

Do you work on both oil and gas furnaces?

Yes, our technicians are trained on both oil and gas heating systems, which is important in this area since many Norfolk County homes have oil heat while others use natural gas or propane. We carry parts and diagnostic equipment for both fuel types. Whether your oil burner won’t ignite, your gas furnace has a faulty heat exchanger, or you’re dealing with thermostat issues, we can handle the repair. We also understand the specific maintenance requirements that differ between oil and gas systems.

What if my furnace is really old - can you still fix it?

We work on furnaces of all ages, including older systems that other companies might not want to touch. Many homes in Medfield have heating systems that are 15-20 years old or more, and these can often be repaired effectively when maintained properly. However, we’ll be honest with you if your furnace has reached the point where repairs don’t make financial sense anymore. Sometimes a repair will get you through the rest of the winter while you plan for a replacement, and sometimes the most cost-effective solution is a new system.

How much does furnace repair typically cost?

Repair costs vary significantly depending on what’s wrong with your system. Simple fixes like replacing a thermostat or cleaning a clogged filter cost much less than major component replacements. We provide upfront estimates before starting any work so you know what to expect. Many common furnace problems fall into predictable cost ranges, and we’ll explain your options if there are multiple ways to address the issue. Our goal is to give you enough information to make a decision that makes sense for your situation and budget.

Do you offer any kind of maintenance program?

Yes, the Dempsey Comfort Club provides ongoing maintenance and service benefits for customers who want to stay ahead of furnace problems. Regular maintenance catches small issues before they become expensive emergency repairs, and it helps your furnace run more efficiently. Members get priority scheduling, service discounts, and regular system check-ups. Many customers find that the money they save on repairs and energy costs more than pays for the membership, plus they have peace of mind knowing their heating system is being professionally maintained.

What happens if the repair doesn't hold or my furnace breaks again?

We stand behind our repair work and will address any issues with the specific repair we performed. If the same component fails again due to our workmanship, we’ll make it right. However, it’s important to understand that furnaces are complex systems, and sometimes fixing one problem reveals or leads to another issue, especially on older systems. We’ll always explain what we’ve repaired and what other components might need attention in the future, so you’re not surprised if a different part of your furnace needs service later.
