Since 1989, Callahan Roach has set the pace for innovative solutions in HVAC flat rate pricing. We were the FIRST flat rate pricing provider in the industry. We understand the HVAC industry because our owners and all of our HVAC Service Operations Consultants have experience working in, owning or managing HVAC companies. We have years of experience doing what you do on a daily basis. We also were the first to offer a complete flat rate pricing service for the swimming pool industry.
