      We got a new a/C furnace replaced in July with D & A. They were quick to replace and take our money but have been unresponsive ever since. I have been trying to contact them since because they never pulled a permit or had an inspection through the city and and they will not call me back. . My husband has also been calling them because they told him to call when we start using the furnace because as part of our cost they need to do something to it and they will not call him back. They were happy to talk to us prior to the job being done but once they got our money the customer service has been terrible.

      Austin & Noah took care of me when I had problems with my AC & the job didn’t get done the first time around. I called them & they quickly got back to me & made things right. Excellent customer service.

      I've used D &A for my HVAC system maintenance for years. This year it went out just like they wanted me it was coming. They installed a new system in just one day. Ishmael is great and so are his crew. We upgraded with the uv system and micro dust filter. The difference in air quality is amazing. No more allergies. I would recommend them. They are friendly honest and caring

      Good genuine people who do honest work. I had them install a new AC and Furnace on an old house that had no AC. Their price was 8k cheaper than Applewood and they had real brands iv heard of. They spent the time to explaining what was going on with my lack of return vents in the bedroom. Work was done fast and clean. AC is icy cold and quiet.

      Austin helped us 2x during 2021 and every time was a great experience, I recommended them to a neighbor and she shares the same opinion. He saved me money both times by solving the issues with creative and professional decisions on our 20 yr old ac and furnace. Austin is very attentive, personable and knowledgeable. I will call them once ready to replace my old systems, I’m sure they will do great.

      We had our HVAC die in the middle of a heat wave. Other companies couldn't get to us for a week. One actually cancelled their appointment with us. Daniel came right over and explained what we needed, which was a new HVAC. They came out the next day and put the who thing in, then came back the next day to tweak it and make sure it worked perfectly. I will always support a company that wants to get things right. Oh, and did I mention they were 50% less expensive than our other quotes? Highly recommend.

      Let me tell you what, these guys are first class. It’s a small family owned business and I wouldn’t want to do business any other way. Dan and his crew , installed my system on darn near the coldest day of the year. It was a high of 9 degrees and the wind chill had to of been -5. They did the furnace and ac in one day! No complaining and got the job done in under 9 hours. Great to work with. Very knowledgeable and prices were spot on. Even lower than other companies. They even had financing!! Call them. You won’t be disappointed!

      Furnace was leaking. I called Daniel at 7:15 on a Saturday morning during a heat wave and the system was fixed by 11 am. Very responsive and great service.
