I am building a “barn-dominium” to live in while our house is built next year. In doing so, I decided to do all the construction myself. I have lots of experience in electrical, plumbing, and HVAC and decided to install my own system. My experience is dated, and I did not feel comfortable brazing the line sets, especially with the new R-410 and nitrogen flush. Plus, I did not have the equipment. So, after I got everything installed I hired an individual (NOT these guys) to braze the lines for me. He messed it all up and ruined the liquid line service valve, bled off all the freon, and generally left me in a mess.
I hunted around for someone that could help me out and found Campbell Air. I was very impressed with his knowledge and skill. I am an Electrical Engineer by training, but have several good friends that are Mechanical Engineers (one was a professor at the University of Arkansas for many years). I am well versed in thermodynamics and the refrigeration cycle, and I can tell you Danny knows his business. His equipment was very good and he knew how to use it. He was fast, professional, friendly, and very easy to work with. The brazing job he did was excellent (he replaced the liquid service valve for me). It has been working flawlessly since he finished the job for me.
When we build the house, I will be calling Campbell Air Conditioning to install the new systems! I wholeheartedly recommend them for any HVAC work!
