Hesse Heat & Air (Formerly Hesse-Schniederjan)

Hesse Heat & Air traces its roots to 1972 when the Hesse family founded what was then known as Hesse-Schniederjan in Gainesville, Texas. More than five decades later, the contractor still operates under that same family-owned model, now carrying a perfect 5.0-star rating drawn from 725 customer reviews. The company maintains 24-hour availability every day of the week, ready to respond to heating and cooling emergencies across North Texas. Beyond Gainesville, Hesse technicians service homes in Denton, Celina, Sherman, Pottsboro, and several smaller communities including Lake Kiowa, Muenster, and Whitesboro.

The Hesse catalog goes well beyond standard split-system replacements. The company is listed as a Lennox dealer, giving homeowners access to a recognized brand with factory-backed rebates on qualifying high-efficiency equipment. Specialty offerings include geothermal heat pump installation, ductless mini-split systems for homes without existing ductwork, and the REME HALO UV air sanitation system designed to reduce airborne contaminants. Hesse also handles new construction rough-ins and offers financing to help homeowners manage larger replacement projects without large upfront costs.

Five-star reviewers repeatedly named individual technicians and described specific problems those technicians solved. Sean spent time walking a homeowner through the condition of two AC units, answering every question patiently and delivering practical recommendations without pressure to upsell. Victor encountered multiple wiring faults during an HVAC diagnosis, took the initiative to correct each one, and correctly identified the root cause of a recurring issue other contractors had missed. Garrett performed a summer repair and returned for a scheduled annual inspection, arriving on time both times and maintaining a professional demeanor throughout.
