I honestly can't say enough good things about D&M heating and air conditioning. We had a serious issue that needed attention. I called them and they were here the next morning. Dan was so personal, honest and truly concerned about our furnace. It was beyond repair. He was honest and upfront and extremely knowledgeable. We hired them to install a new furnace and all was said and done and installed within a couple of days. Michelle and Kailey were so helpful and thorough. Bill and Brandon installed our furnace. They were polite and professional and absolutely knew what they were doing. I'm a firm believer in supporting local businesses and have been in this area my whole life and without a doubt D&M has been the kindest, most honest and professional business I've dealt with. I won't use or recommend any other HVAC company. D&M has a forever customer. Thank you Dan, Michelle, Kailey Bill and Brandon so much for a stress free, professional and friendly all around experience.

Always happy with D&M they are very good at what they do. They are also very caring. They've taken care of my elderly sister and couple times, once with her heat and once with her air conditioning and they were amazing with her, and very quick!!! I recommend them 100% 👌

I recently had the pleasure of working with D & M Heating and Air Conditioning, and the level of service they provided truly exceeded my expectations. From the moment I reached out, Dan and his team demonstrated exceptional professionalism, friendliness, and genuine care for my heating issues. Scheduling was handled smoothly and with great consideration, especially regarding my night-shift work schedule; which I sincerely appreciated. Their willingness to accommodate my needs reflected a level of respect and understanding that is not always easy to find. When Dan and his crew arrived, they were prompt, courteous, and fully prepared. They took the time to thoroughly assess the problem areas with my furnace and explained each step of the process in a clear and straightforward manner. Not only did they resolve the issues efficiently, but they also provided valuable education on proper furnace maintenance and preventative care. Every question I asked, no matter how small, was answered with patience and expertise. Their commitment to making sure I understood how to keep my system running safely and effectively truly stood out. What impressed me most was the genuine sense of customer service and community focus that Dan and his team bring to their work. It was evident that their goal extends beyond simply completing a service call; they strive to build trust and long-term relationships with the people they serve. Their dedication, knowledge, kindness and even humor made the entire experience positive and stress-free. I wholeheartedly recommend D & M Heating and Air Conditioning to anyone in need of honest, reliable, and highly skilled HVAC professionals. They exemplify what a local company should be with their dedication to quality work, exceptional service, and the wellbeing of their community.
