I've only had to use Bradham Brothers twice in eight years (thankfully), but both times they've been prompt and courteous and charged me less than I expected. The latest time I called on a Monday morning and asked them to come the following day. They put me down for the morning and called beforehand to tell me they were on their way.
My A/C was coming on but not blowing cool air, and they fixed it for $230 - no muss, no fuss, no up-sell. As a single female with no knowledge of HVAC units, it's comforting (and rare) to have a reliable company you can trust not to jerk you around. I can't recommend them highly enough!
