Am extremely happy with the customer service provided by Rockwall Heating and Air. I had an A/C failure during overnight hours and also had a heat-related illness with a family member. When I spoke with the dispatch agent, Mindy, and explained about my wife's illness, she and the service technician routed their schedule in order to make an early accommodation to repair my A/C a few hours later. I am very grateful for their attentiveness to customer service.
