Five states, one standard of mechanical service.
GMR Heating & Air delivers commercial HVAC, refrigeration, and mechanical services across five states from our headquarters in Carrollton, Texas — with the same standards, documentation, and response expectations in every market.
Regional coverage, delivered with the same standard everywhere.
Our coverage model is built around multi-site owners, facility managers, and government clients who need one accountable contractor instead of a patchwork of local vendors. Work is coordinated from Texas, staffed by licensed technicians, and documented the same way in every state we serve.
Texas, Georgia, Kansas, Louisiana, and North Dakota each present a different climate and regulatory environment. We plan equipment selection, maintenance intervals, and emergency response around those differences rather than applying a single template everywhere.

Texas
Home base for GMR crews, dispatch, and project management.
Texas is where GMR Heating & Air is headquartered and where the majority of our commercial HVAC, refrigeration, and mechanical work is delivered. From Carrollton we cover the Dallas–Fort Worth metroplex daily and mobilize statewide for planned installations, retrofits, preventive maintenance programs, and emergency service calls.
Our Texas operation carries the equipment inventory, licensed technicians, and vendor relationships that let us self-perform most scopes without waiting on outside trades — which is what keeps response times short for multi-site owners and facility teams.

Georgia
Southeast coverage for corporate, healthcare, and municipal facilities.
GMR supports Georgia clients with commercial HVAC service, refrigeration support, and mechanical project work across office campuses, healthcare buildings, and public facilities. Humid Southeast conditions put constant load on cooling equipment and dehumidification, so our Georgia scopes lean heavily on airflow balance, controls, and preventive maintenance.

Kansas
Midwest support for distribution, warehousing, and light industrial sites.
Kansas facilities swing between hard freezes and high-heat summers, and the buildings we support — distribution centers, warehouses, and light industrial plants — have to hold conditions through both. GMR provides scheduled maintenance, rooftop and split-system replacement, refrigeration support, and mechanical repairs across the state.

- Kansas City
- Overland Park
- Topeka
- Olathe

Louisiana
Gulf Coast service for commercial, industrial, and infrastructure facilities.
Louisiana projects demand equipment and installations that tolerate heat, humidity, and coastal corrosion. GMR delivers commercial HVAC and refrigeration service, mechanical piping work, and equipment replacement for facilities that cannot afford extended downtime during peak season.
- Baton Rouge
- New Orleans
- Shreveport
- Lafayette
- Lake Charles
North Dakota
Cold-climate mechanical work where heating reliability is non-negotiable.
In North Dakota, heating is life-safety infrastructure. GMR supports commercial, energy, and industrial facilities with heating system service, boiler and rooftop equipment work, refrigeration support, and mechanical repairs built for sustained sub-zero operation.

Supporting Organizations Across Multiple Markets.
A rooftop unit in Fargo and a rooftop unit in Baton Rouge fail for completely different reasons. Regional experience means specifying the right equipment, setting realistic maintenance intervals, and knowing which failure modes to inspect for before they take a building offline.
It also means understanding local permitting, inspection expectations, and jurisdictional licensing so projects move forward on schedule. GMR maintains that awareness in every state we operate, and coordinates it centrally so clients get one point of contact regardless of location.
