Paul went above and beyond. I would definitely recommend this ac company to anyone. Small owned local business, that’s very fast, friendly, and just amazing in general. Paul was able to come out with in 2 hours of calling him just for a quote, but ended up helping us out immensely; had another company that came out and wouldn’t even trouble shoot the system, and told us it was going to be 6500$ for a new system, he was able to help us out for a hell of a lot less. Honest, Professional, friendly, and full of integrity and knowledge. Definitely will not use a different company while I live down here.

Mills is beyond OUTSTANDING! The Customer Service Representatives are the BEST we have ever worked with. They go out of their way to ensure we receive the BEST service possible each and every time we call. We have a condo in Destin, but live in Atlanta, Georgia and they have always been quick to respond and ensured our guests were never inconvenienced. Richard, Allen, Terry, Megan and Jennifer are ROCK stars! Thank you for all of the years of EXCELLENT customer service - we would never rely on any other company for our HVAC needs.

I've done business with Mills for many years and they've always given me great service, but they've really gone above and beyond this summer! Not only did they respond quickly to troubleshoot and help me keep my old unit going as long as possible, but also provided a detailed assessment of my home to find the most affordable and efficient replacement unit. They managed to get right to me at their busiest time of the year and worked around weather issues to get the installation done quickly. I didn't get everyone's name that came to the rescue, but many thanks to Paul, Richard, Ross, and Terry. You guys are THE BEST!

I would have given a five star rating had the one technician not treated me like I should have known what to do when they first installed the unit and there wasn't any cold air coming out. When I called this person was very rude. I told him "I'm not an A/C person, hence the reason I hired you and then you want to blame me because I'm not aware of how the unit works? They did fix the problem and the unit has been working fine. One would assume you'd insure the Freon had been turned on/tested before signing off on the job?????????

We have been customers of Mills Heating & Air for many years and always get great service and prices. This is very important as we have Destin Getaways Vacation Rental Co. and buy many new AC units as well as repairs to all our condos and homes that we manage.
