Dan is the best heating and air tech. Bought a new house with a system I’m unfamiliar with and he came buy checked over the system. Showed me what to watch and general maintenance on it. Very professional, courteous, and informative. These guys are the only ones I’ll use on any heating and air. He’s install 3 other systems I. 3 separate homes I’ve own. Thank you guys for everything.

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.

On 7/27/2025 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.
