I was given the name of Father & Sons by at least three different people. I called them spoke with a pleasant woman who would check the schedule and return my call. She promptly did, and the serviceman arrived the same day. Their service charge was more than reasonable (I've had others to compare it to) as was their charge for a freon fill. Their price for a new unit (which I know I need, and wasn't a scam) was a bit high, but their service was prompt and excellent. I've since recommended them to others.
