Absolutely wonderful! I was told by another company that I needed a new air conditioner and mine could not be repaired. Darrien came out and said it could be repaired. I got a call later that said, that not only could it be repaired but the part that needed to be repaired was under warranty and the cost was going to be about half. I went from paying $8,000 for a replacement to $1,600 for a repair. I'll be using them again. Don't fool around with another company, it's not worth it.
