David was able to come fix our issue with extremely short notice. He was professional and courteous and resolved the issue promptly.

Very knowledgeable and upfront on what was going on and what it would take to fix. Responsiveness was stellar and workmanship great.

D&M responded quickly when our 30 year old AC unit had failed. I was impressed with the amount of insight they had when taking a look at my system. Other companies could wait to just tell me a number but D&M was exploring all possibilities to get us back up and running. Would highly recommend.

The first time we met Dan and his crew with D&D we were so comfortable having them in our home. They were courteous and friendly which put us at ease. But the work they did is what shined through the most. We had an extremely old furnace that needed to be upgraded and the new system retrofitted since the prior one was so old. Finally after several years, we decided to install AC to eliminate our swamp cooler that was causing health issues. We got a great price and excellent service for that install also. They had to run electrical and freon lines from inside to the unit outside. It all looks professionally done and works perfectly. The normal service calls are top notch for cleanings, we have never needed a repair either. We are very satisfied with the work D&D has done for us over the years and they are who we recommend to all our friends and family. You won't be dissapointed calling them!

Great customer service. They came and quickly diagnosed the problem and fixed it.

I have only the best things to say about D & M. Karen was able to get me an appointment quickly. Alyssa, the technician who came out was just AWESOME! She was prompt, a person of her word. Her knowledge was evident right away. Alyssa was also generous with her time and considerate of the cost for me. It's obvious that she cares about her work and the people she helps. D & M is fortunate to have her as one of their team members. I heartily recommend D & M! 02/24/2023 Once again I was so pleased with D and M. Alyssa and Sean came out, and checked everything. They helped me become more acquainted with the newly-installed "dampers." They were patient, kind, and generous with their time. I highly recommend the company's "maintenance plan. " This company is top notch, and the employees make it so! 03/27/2023 Decided on a complete new furnace. Timothy came out first to check on the whole system, finding out that the motor was kaput. Dustin and Elijah did a superb job on the installation of the new furnace. Timothy was great with his troubleshooting and kind advice. Dustin and Elijah worked fast and were clean to boot! I continue to be a most pleased and grateful customer of D and M! 07/20/23 I continue to enthusiastically endorse D & M! I highly recommend their "service plan," as it saves money, and can detect potential problems or those currently going on. Thanks to their yearly service, I found out that my air conditioning unit wasn't working properly. My "hat's off" to Tim Silva for his expert diagnostics and electrical work! What an asset he is to the company! Tim was also prompt - a person of his word, and worked quickly to solve the "issues" going on. Once again, get the "service plan." You won't regret it! 06/23/25 I continue to be a very pleased customer! Recently, I called on a Saturday, considering it an emergency that my air conditioning unit wasn't working. Technician Amber came and solved my problem. She was prompt, kind, and patient. Definitely knew her stuff! I highly recommend this company! I also have their seasonal maintenance plan, checking on both the furnace and the a/c unit depending on the season. This plan is reasonable, and practical to have. Thank you Amber for a job well done, and thank you D and M for being there for your customers!
