I am a contractor, and I have used American Comfort Heating & Cooling as a subcontractor to handle HVAC installations on new homes for over four years. I also use them to do work on my personal residence. Their employees are very professional people, and they work well with others. They are very friendly and cooperative. I also like the fact that they show up when they are supposed to. They perform their jobs well, and I highly recommend them! Four and One Half Stars on Service!
