I first want to say, that I own my own Air conditioning business and i am very picky. The sales man was very professional and was not pushy at all. He answered all my questions and i had a lot of them. When the install date arrived, I received a phone call from there office that they are on there way. When the crew arrived, Ryan explained in detail exactly was was going to happen, every thing he said went as plan. Ryan had to trench under cement to run the piping, after that they were installing pipe, valves, digital thermostat, low voltage wire, solar panels on roof top, brackets, they even spray painted the pvc piping and matched the exact color of my house. They even cleaned up, they left no mess. When they were all done, Ryan explained and showed me how to work the thermostat. There were a total of three workers, I did not mention the other two guys yet, I do not remember there names, sorry, but they were also great people and great workers, I even had some technical questions for them and they were able to answer all of them. Every body involved with this project were very polite, professional and clean. awesome job, highly recommend. My swimming pool is about ten feet deep, my pool would never get over 75 degrees, even on a 100 to 105 degree day. Now my pool gets 90 to 95 degrees. Thank you so much .
