Have used D&A Heating and Air for years to support the HVAC needs of the commercial outfit I work for. Unfortunately they seem to be another company that's fallen prey to "cutting costs" by removing their scheduling and customer service reps in favor of AI call bots. The technology is broken and i'm tired of repeating myself just so some greedy owner can cut another workers salary. Won't be using them again
