Built on relationships. Driven by performance.
GMR Heating & Air is a veteran-owned commercial HVAC, refrigeration, and mechanical contractor headquartered in Carrollton, Texas, serving commercial, industrial, and government facilities across five states.
A mechanical contractor built around accountability.
Commercial HVAC, refrigeration and mechanical services delivered with the discipline of federal service.
We handle the systems buildings cannot run without — rooftop units and chillers, walk-in refrigeration and cold storage, boilers, piping, and the controls that tie them together. Our work spans planned installation and replacement, preventive maintenance programs, and emergency response for facilities that cannot absorb downtime. What sets the company apart is not equipment; every contractor buys from the same manufacturers. It is discipline: licensed technicians, self-performed scopes, honest assessments of what a system actually needs, and a single point of contact who stays accountable from the site walk through closeout.
