B&B Hearing and Air Conditioning performs anywhere from my own home, to a church they've done for me, and even some commercial buildings. They do stuff most guys probably would not do and they're very dogmatic about their service. We just finished work on a Mitsubishi a/c unit and they came out on the weekend to do it. To me, that's excellent because I'd like to keep my clients happy. Not only are they responsive, the prices are reasonable for what you get.
I know that when I recommend them to other people, it's not going to have repercussions on me and I know the prices are going to be right. At the end, not only am I going to be happy, my clients are going to be happy.
