Great company, even better service. We’ll be using them from now on for all commercial and residential HVAC issues. Dan and John were timely, knew their stuff, fixed the issue fast, very nice, and the bill was over $200 cheaper than another company that came before, that didn’t even fix the problem! Their staff is amazing, both in person and over the phone. Kailee got me an appointment within 24 hours, and they even showed up early (BY 7 HOURS), which was a real lifesaver.

Amazing company, don’t go anywhere else for your HVAC needs. Quick, cost effective, and amazing service, both on the phone and in person. They saved our fireworks store from the heat within 24 hours, just before our big day. Dan was very honest, reliable, and knowledgeable, and they fixed the issue within an hour, showed up early (thank God in Heaven), and gave us a very good price. Their team is fantastic.

Sparky's Dream Fireworks II
had this to say:
Could not recommend this company enough! We are a fireworks store, and our air conditioning went out a week or two before July 4th. Obviously, our big day was coming up, and we needed A/C desperately! After trying several companies that either bailed, were too expensive, or didn’t work on commercial units, we finally found D&M through a mutual friend. We called the evening of July 2, and were told they had an installation the morning of July 3, but they would be there in the evening. Not only did they show up at 10am, but they fixed the issue (that no company could even find before) within an hour, were very friendly, and gave us a killer deal! They’ll be our HVAC guys from now on! Very friendly family-owned business.

I can't say enough good things about D&M! We were recommended to this company by family friends, and I'm just so glad we found them. We had ice building up on our outside AC unit and the house would not cool down, right in the middle of a super hot week with a heat advisory. The office was extremely kind and thorough. Dan was amazing and came out incredibly fast after we called. He quickly diagnosed the problem, explained everything in simple terms, and had it fixed in no time. He was professional, friendly, and made sure everything was running properly before he left. It’s hard to find that kind of prompt, honest service these days. We’re so grateful and highly recommend to anyone needing AC/heating help!
