I have a awesome ac/heat guy that takes care of my house and my rental houses as needed. He knows his shit and has never once charged me a price I was ticked off about.
If you live in my area and need help you can pm me for his #.
At the same time he is getting ready to retire soon, so please pay the favor back for in the future when I need someone great myself.
(while he is thinking about retiring, he is trying to train his son to carry on the business, and hell no, his son is not that good, I will have to look again).
