D & M Heating's website lists Oxford, Lincoln and Cumberland as its service area and says it offers 24/7 emergency service. A customer who has used Derek for a personal home and several rental properties says he is still the only person they call for heating needs, and that he takes the time to explain everything. A 2026 customer whose heat had not worked for a few days said Derek came within 20 minutes of the call and resolved the issue. A 2026 customer with a short-cycling boiler said they called about 9:15 in the morning and he was at the house by 9:45. That 2026 customer said he installed a new motor at a very reasonable price and went over the boiler to make sure it was running smoothly. A 2025 customer said that each time they called, after midnight, Derek showed up within 15-20 minutes and got the furnace up and running. A 2025 customer said Derek replaced their propane furnace and water tank and cleaned up after himself.

I’ve been using Derek for the past couple of years for both my personal home and several of my rental properties, and I can’t say enough good things about him. He’s knowledgeable, honest, dependable, and always gets the job done right. He’s also very responsive, easy to work with, and takes the time to explain everything. I’ve recommended Derek to several friends and family members over the years, and they’ve all had the same great experience. Everyone has been impressed with his professionalism, quality of work, and reliability. To this day, Derek is still the only person I call for my heating needs. It’s hard to find someone you can truly trust, and Derek has earned that trust time and time again. If you’re looking for someone who genuinely cares about his customers and stands behind his work, I highly recommend him.
We had a short cycling boiler. Called D&M about 915 in the morning and he was at our house by 945. We needed a new motor which he installed quite quickly, at a very reasonable price, as well as going over the boiler to make sure it was running smoothly overall. Very friendly and professional. Definitely calling him again when we need any work done.
I'm really glad I gave D & M Heating a call! Our heat wasn't working for a few days and other companies weren't really helping - Derek came within 20 minutes of me calling and resolved our issue beautifully. I would 100% recommend giving them a call for any of your heating needs!
This is the second time that I've used D&M Heating and each time that I have called it had been after midnight and Derek showed up within 15-20 minutes he got my furnace up and running corrected the issues Derek is compassionate knowledgeable fast and efficient Derek is also clean respectful and professional and I highly recommend his services
Derek replaced our propane furnace and water tank; also a couple of smaller things were fixed that needed addressing. He was prompt in responses, professional and kind. He cleaned up after himself. He treated us with courtesy and respected us and our home. I would recommend him and his services to all.
