I have worked with them on a couple of projects that needed ac/furnace work after long periods of non use. they were able to bring one AC system back from the dead to close a house deal and charged up the AC's on another place. Tim is my first call as he has been a straight shooter telling me when he can fix something or when it needs to go to the scrap pile.

He is honest. He could have completely ripped me off. The only problem was that I needed to change the filter.

I used Dad's on the recommendation from a local contractor. They initially repaired a really old AC system for me. They did a decent job. I then replaced 2 heating and cooling systems from them. As it was part of a renovation job, there were some hiccups but they really stood by their work. The deal with them is that Tim is really "matter of fact" - that is a diplomatic way of putting it. That being said, he is honest, gives you a good price, shows up whenever needed, and is an all around decent person. In my view, their good work and honesty is what sold me.
