"AMAZING customer service!! My a/c went out this weekend - yes, THIS weekend the hottest weekend of the year. I called the office and they were able to have a service technician out within 5 hours. The truck was a sight for hot and sore eyes for sure.
He did a wonderful job finding and fixing the problem as quickly as possible. 10/10 highly recommend!!"
