Precision Air is truly one of the best companies that I?ve ever had the privilege to work with. The company employees are extraordinary. After my husband and I decided that we wanted to explore having a geo-thermal system installed at our home, I checked out companies on Angie?s List. Precision Air had great reviews so we called them first to see if installation was possible at our house and to get an estimate. We didn?t call anyone else. Why would we? Don Vogt was obviously knowledgeable and represented a company that had installed more geo-thermals than any other in the area. We also trusted him almost immediately. He?s that kind of guy. He wasn?t just a salesman. He was concerned about us as individuals who were getting ready to make a big investment in our house. He really cared. And never in the process of the installation were we disappointed. He did everything he could to make us happy with our unit. That trust deepened when the actual installers arrived. I?m never seen three men work harder or who were more focused. I don?t think that they wasted a second during the entire installation process. Tim Brewer, Richard Mays and Joel Rodriquez have to be about the best professionals around in their field. They were considerate, polite and just good all-round people. After installation, there were a few problems, as there will be with such a sophisticated system. But when it was obvious that some adjustments had to be made, Jeff Holland came out for a final inspection, saw the problems and had them remedied immediately at no extra cost to us. Now I ask you, what more can a client expect? As I said at the beginning, Precision Air is an excellent company because they have excellent employees doing excellent work. It doesn?t get any better than that. I give them five stars (out of a possible five stars) with no hesitation. They are the best.
