My heater was acting up. It was making noises and there was a burning smell coming from it. So I called Holley Heating & Air Conditioning Company to come out and take a look at it. They ended up replacing a part and that took care of the problem. They were very prompt to respond and very nice people overall. They came across as a very professional and well-organized as well. I have used them in the past with good success, so that is why I called them when I had a problem! I would highly recommend them to everyone!
