"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 have had the same person clean my carpet. He has always been on time for the appointment, clean, and well dressed. He works very efficiently, no standing or sitting around. I felt comfortable being at home alone with him for the duration of the appointment."

"Overall, we were very satisfied with the knowledge and quality of work that Covenant LLC provided. We had Covenant LLC install a radon mitigation system for our basement. Initially my husband and I met with David for the estimate and consultation. David spent the time to explain how radon can get into the basement, what the system would look like, and how he was going to make sure it was working. After meeting with David at Covenant, we met with a competitor who were definitely not as knowledgeable, were not going to seal any of the cracks or holes in the foundation or even follow industry standard by venting through the roof of the house. The day of install the crew was personable and professional and if they had any questions, they asked. The 3" pipe that Covenant had to install to run through a closet and into the attic. In order to do this, they had to drill through the porcelain title floors and run through 3 shelves. They spent extra time to jig-saw cut the shelves around the pipes and they took special care not to crack any of the porcelain tiles and when finished it looked like it was built with the house. After completion, Covenant came back and tested the radon levels which were reduced to below their guarantee, which itself is orders of magnitude below the EPA limit. We were probably not the easiest clients to work with as we had Covenant move the roof penetration several times until the noise was completely unnoticeable. David was always polite and professional and he wouldn't be satisfied with the job until we were satisfied. We highly recommend Covenant Air to anyone who is considering these services."

"Work went very well. Technician was here for a long time and did a very thorough job of cleaning and sanitizing. I got more effort and attention than I expected for the cost. The price below reflects the cost I paid for the Angie's list deal that I purchased (I believe it was $110 paid to Angie's list) and $175 that I paid to the company directly for the second floor unit and system. The total of $285 covered two units and trunk lines along with 28 vents."

"Jim is local. It went great. Jim Ferrell is a professional of the highest caliber. Responded quickly, took care of my problems, and advised me as to better means of protection than I had. He came back a second time to uninstall software that I purchased that did not provide adequate protections and installed free software that would do the job. He did the work through remote connection, but is available on site if necessary.
For those people needing help on getting red of malware, viruses , etc. on your computer, Jim is local, better than all thse remote out of state location providers, is a mature, highly trained professional in this area.
If you go to local computer stores you get very young people that can do a basic job, but are no where near the professional level of Jim.
I highly recommend Jim to anyone that needs these type services.
