I have been with Carbon Valley Heating & Air for a number of years, and have always gotten along great with them. They always do good work. They recently put in a new furnace for me, and I am so warm now! They always show up on time, and are very friendly people. I have recommended them to other people, including my daughter, who also had them install a new furnace for her. She was just as pleased with them as I was! And gosh, every time I call them, they come right out for me! I really appreciate that!
