Canoga Park Heating & Air Conditioning came out to my residence for the first time I was using them. They were fantastic! I had them come out to do some repair on the air ducts and everything turned out great. The technician showed up right on time. They seem very honest. I really liked that they did not overcharge me. The tech seemed to know exactly what the problem was and fixed it. I would highly recommend using them, as I will be using them in the future. Oddly enough, after I had the work done, I discovered my good friend has been using them too. She is just as happy as I am with them.
