"Advanced heating and air solved our problem of an uncomfortable sunroom. They offered solutions, options, and information about a great system that was new to us...the Gree mini-split. We chose the Gree. The indoor components were slim-lined and fit right in with the room. The best part is that they were whisper quiet. (Also the outdoor opponent). The technicians were courteous, knowledgeable, and efficient. Thank you Advanced heating and air for making our sunroom livable and enjoyable. Reg and Linda Jellicorse"

"I cannot speak highly enough of David and his team. When I got a moderately high radon reading on the home I was selling, I had to take care of it quickly so that my closing could go through. David worked me into his schedule and came to my home the day I called. He was delightful, did a thorough inspection, and gave me an estimate. I subsequently got an estimate from another vender, and it was $1,000 more! Not only that, but David had figured out a way to perform the remediation without installing unsightly pipes either on the inside or outside of the house. This involved him working in a very shallow attic space to run the pipes up through the heating ducts, but he was happy to go the extra mile. On the day of the work, David and his wonderful assistant Ryan arrived on time, and spent the better part of a day installing the system. They were convivial and professional without being the least bit instrusive - I enjoyed the experience! After the installation, David explained it to me in detail, and left a radon kit so that my buyers could check the new levels. Not suprisingly, my buyers are more than happy with the results. If you need to have this job done, call David. You won't regret it!

"The tech was really nice and did a good. They were suppose to install a carbon monoxide detector but have to wait to see how many they needed to order. They have not returned as of today. Left area clean."

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."
