Claim This BusinessCAST Heating and Air Conditioning operates as a family-owned HVAC contractor serving Combine, Texas and surrounding communities including Fate, Royse City and the greater Prosperity area. Built around owner Jamey Cox, who brought three decades of industry experience to launch this venture, the company has earned a flawless 5-star rating across 33 customer reviews. Their crew maintains extended service hours from 6 AM to 8 PM six days a week, accommodating homeowners who need evening appointments after work. This contractor handles both residential cooling systems and the furnace components necessary for infrequent but critical winter episodes in North Texas.
What distinguishes this contractor emerges in the details reviewers recount. When Mike D needed guidance on replacing a stubborn system from the 1980s, Jamey walked him through SEER ratings, available tax credits and proper tonnage sizing without pressuring a sale. He arrived at the job with his son and employees, ensuring the crew matched the scale of installation work. When the concrete pad proved too small for the new unit, the team drove to retrieve additional pads mid-job rather than postponing. Recognizing the old gas line deteriorate, they installed a replacement and did not add the charge to the final invoice. Jessica Patterson described the same responsiveness when her 1990s AC unit began sparking, with Jamey talking her through shutting off the breaker before the crew arrived and completing full replacement in a single day.
Customers repeatedly mention feeling informed rather than sold. Susie Stockard credited the crew with patiently explaining each step while installing two units in her home. Aaron Lindeman appreciated that Jamey explained the repair process as work progressed. Jessica noted she received guidance on how her new system would perform differently than the aging unit it replaced. These accounts suggest a contractor who prioritizes homeowner understanding alongside technical competence.
All five detailed reviews award 5 stars, with three explicitly naming owner Jamey Cox as the primary technician. Four reviewers highlight the company handling systems over 25 years old, and two mention unexpected issues being resolved during the appointment without additional charges. No negative feedback appears in the dataset.
