Uni-Serve Air Conditioning is a Houston-based HVAC company that stands out on a specific credential: it is owned and operated by a Texas Licensed Professional Engineer (PE), making it one of the few residential HVAC contractors in the area with engineering-level oversight built into the business itself. Combined with Class A Air Conditioning Contractor licensing and a 5-star rating across 103 reviews, this is a company that can back up the technical claims it makes.

The service area is broad — Uni-Serve covers Houston proper and a wide radius including Atascocita, Bellaire, Cypress, Deer Park, Huffman, Humble, Katy, Kingwood, Magnolia, Missouri City, Pasadena, Porter, Spring, Sugar Land, Tomball, West U, and The Woodlands. Both residential and small commercial systems are accepted, and the company services all brands of equipment.

Core services include AC repair, heating repair, HVAC maintenance, and full system replacements. The company's Uni-Shield Maintenance Plan is a recurring subscription product for customers who want pre-scheduled spring and fall checkups with a consistent point of contact. Emergency repair services are available alongside the planned maintenance track.

Customer reviews reflect a few consistent patterns. Technicians are named frequently — Summor, Jason, Colton, Ryder, Jake, and Frank all appear across recent reviews — and are praised for explaining what they found, walking customers through options, and teaching rather than just fixing. One reviewer highlighted that Uni-Serve tries to repair systems first rather than immediately recommending replacement. Another appreciated that a technician provided a verbal report of findings after each step of a maintenance visit.

The duct replacement work documented in at least one review — pulling and replacing 20-year-old ducting in a hot Houston attic in November — illustrates the kind of physical job Uni-Serve takes on without complaint. Online booking is available, and the company accepts credit cards and NFC payments.
