The company holds LEED, CEM, and NEBB-related staff certifications and has earned the 2018 Siemens IFO of the Year award and a U.S. EPA ENERGY STAR certification for its Fargo office.

The company makes money through a mix of one-time installation revenue from new construction and retrofit projects, recurring service and preventive maintenance agreement (PMA) revenue with 24/7 emergency support, ongoing HVAC parts sales from regional warehouses, and professional services for facility consulting, retro-commissioning, indoor air quality, and energy management. Project sizes are quoted individually, with disclosed projects in the approximately $500K range.

Scale indicators7 records

Recent moves6 records

Expansion highlights5 records

Direct peers

• Automated Logic (Carrier): Carrier-owned BAS vendor with a regional dealer/integrator model closely mirroring G&R's Siemens IFO setup. Targets the same healthcare, education, and government end markets with similar project + recurring service economics.
• Control Solutions & Services (CSS): Mid-sized regional BAS integrator with a comparable mix of design, install, and recurring service. Competes for similar healthcare, education, and government projects in adjacent Midwestern geographies.
• Alerton: Honeywell-owned BAS vendor selling through regional system integrators. Highly comparable channel model and mid-market commercial focus, competing head-to-head on healthcare and education project bids.

Emerging players

• 75F: Cloud-native smart building controls provider targeting light commercial and mid-market customers. Represents the newer, software-led model that competes with legacy Siemens- and Honeywell-based integrators like G&R on smaller, IAQ-and-efficiency-driven retrofits.
• Reliable Controls: Independent BAS manufacturer that sells exclusively through authorized dealers — analogous to the Siemens IFO model. Targets small-to-mid commercial buildings with a focus on energy efficiency, similar to G&R's positioning.

Broad incumbents

• Johnson Controls: Major BAS and HVAC incumbent with its own controls platforms (Metasys, Facility Explorer) plus a global service network. Direct overlap with G&R on building automation design, install, and service for healthcare, education, and commercial customers.
• Trane Technologies: Global HVAC and building services incumbent that designs, installs, and services Trane-sourced and third-party BAS for commercial buildings. Overlaps with G&R on controls integration, energy services, and service contracts, but at vastly larger scale and broader geographic reach.
• Siemens Smart Infrastructure: The vendor behind G&R's entire product line (DDC, Desigo, APOGEE). Functions as both a strategic partner and the largest potential competitor if Siemens shifts to direct sales or consolidates IFOs in the upper Midwest.
• Honeywell Building Technologies: Honeywell's building automation division (incl. Niagara, WEBs, and now NIAGARA Framework partners) competes with Siemens Desigo in the same project bids G&R pursues. Comparable offering across BAS design, energy management, and recurring service.

Others

• O'Connor Company: Sister division under the HVAC Elements (formerly O'Connor Group) marketing umbrella. Provides commercial HVAC equipment distribution to the same regional contractor and building owner base G&R serves, making it a closely adjacent — though non-competing — peer.
