A-1 United Heating and Air was actually great. Even though I had very little interaction with the actual work crew (and the work seemed to be just fine), it is the sales representative that I was very impressed with. His name is Damon Hill and he was outstanding and provided excellent customer service. I can't give you enough superlatives about him, he was great.
And they've been consistently good, I've lived in this house for 10 years plus and they have always done a very good job and they did again this last time with our big air conditioning, they were great.
