Built on relationships. Driven by performance.
GMR Heating & Air was built around dependable service, disciplined execution, and long-term customer relationships. Our team supports commercial, institutional, and government facilities with responsive HVAC, refrigeration, and mechanical solutions.
It started with a service truck and a standard.
GMR Heating & Air began the way most respected trade companies do — with a technician, a truck, and a refusal to cut corners. The early work was straightforward commercial service, and the standard was simple: diagnose honestly, fix it properly, and leave the site better than you found it.
Commercial work, from the beginning.
Rather than chase every residential call, the company concentrated on commercial and light-industrial systems — rooftop units, chillers, walk-in refrigeration, and mechanical piping. That focus built depth fast, because the same failure patterns show up again and again once you specialize.
Growth followed the clients, not the map.
Expansion came from clients, not marketing. As facility managers took new roles and multi-site owners added locations, they asked GMR to cover them — which is how coverage grew from the Dallas–Fort Worth metroplex into Georgia, Kansas, Louisiana, and North Dakota.
If we would not accept the result in our own building, it does not leave the site.
Two client types, one standard of work.
Today the company serves two closely related worlds: commercial owners who need uptime and cost control, and government and institutional clients who need documentation, access discipline, and dependable response. The crews and standards are the same in both.
Where GMR stands today.
GMR operates from Carrollton, Texas as a veteran-owned, Service-Disabled Veteran-Owned Small Business delivering commercial HVAC, refrigeration, and mechanical services across five states — with 24/7 emergency support for service clients.
What comes next.
The plan ahead is deliberate: grow the technician bench, deepen preventive maintenance programs for multi-site clients, and continue expanding government and institutional work — without outgrowing the accountability that got us here.
The GMR standard
Built on relationships.
Driven by performance.
Relationships open the door; performance is what keeps it open. Nearly all of our growth has come from facility managers, owners, and general contractors who called us back — and then referred us to someone else.
