My last full experience with Holley Heating & Air Conditioning Company was back in February, and they did very well. They replaced the system in my home and did everything they said they were going to do. I've used them to service my old unit before the winter months, and of course, to have it replaced with a new one. It was a fabulous experience, but I do not plan to use them anymore, as I called them to have my new system serviced a few days ago and was told they would be out ten days from now. I called another company who will be here much sooner.
