M & D Heating and Cooling Inc. says it has been in business for 30 years and lists 24/7 emergency service on its website. A 2026 customer said they put in a new furnace and called them very nice people. A 2025 customer said that when their furnace needed replacing in the middle of January, Dewey did a complete install in just days, then followed through by checking in to make sure everything was good. A 2024 customer wrote that their boiler wasn't working that summer; Dewey called back that afternoon, was onsite the next morning, and the situation was resolved within a few days. That 2024 customer went on to have him perform an addition project a few weeks later and called the company honest, prompt, clean and reasonably priced. A 2023 customer said what Dewey quoted is what he charged. A 2023 customer said they were treated like a person, not a job, during a time when many people had frozen pipes. A 2021 customer said the company put in a furnace and a fuel tank and came to the family's rescue after fuel delivery issues.
Love M@D Heating they put in new furnace very nice people recommend highly
When our furnace needed replacing in the middle of January, Dewey stepped up and did a complete install in just days. He really knows his stuff and is a complete professional. And he followed through - checking in to make sure everything was good with no problems. Highly recommend.
Highly recommend M & D Heating and Cooling, Inc. This summer, woke up to find my boiler wasn't working. Called nearly 7 or 8 companies, but Dewey at M & D Heating and Cooling was the one who showed up and saved the day. He called me back that afternoon and was onsite the next morning. Within a few days, the situation of resolved. We were so thrilled with Dewey's work went on to have him perform an addition project a few weeks later. We found them to be honest, prompt, clean, reasonably priced and most importantly competent. Like he says, "We're Not Comfortable Until You Are" and that turned out to be true.
Awesome guy Dewey is and what he quoted is what he charged no B.S with this guy
They are amazing. During a very crazy time of so many people with frozen pipes, they treated me like a person not a job. They
