John E. Mixson Heating & Air operates as a locally owned heating and cooling contractor serving the Charleston metro and surrounding communities including Goose Creek. The business has maintained operations since 2005, building its reputation on straightforward diagnosis and fair pricing without unnecessary upselling. Currently holding a perfect 5.0-star rating from seven client reviews, the company focuses on residential HVAC repair, maintenance, and replacement services throughout the Lowcountry region.
unlike larger HVAC companies that rely on commissioned salespeople, John Mixson himself handles service calls and works directly with homeowners on every job. Reviewers consistently praise the owner's honesty and integrity, noting he never recommends repairs customers do not actually need. The company prioritizes transparent communication, providing detailed explanations of system conditions and explaining exactly what each repair entails before work begins.
Customer experiences highlight the company's responsive approach. When Tracy E.'s cooling system failed during summer preparation, John arrived within the scheduled timeframe, diagnosed a refrigerant leak, completed the repair and system recharge within ninety minutes, and declined to recommend unnecessary replacements. Another reviewer referenced fifteen years of continued service since relocating to the area in 2005, emphasizing consistent quality and honest assessments across multiple system installations and maintenance calls.

Seven clients have awarded five-star ratings, with three specifically naming John Mixson as the owner performing work and praising his honesty in avoiding unnecessary repairs.
