What Alliance Group Services does

Alliance Group Services, LLC is a 100% employee-owned (ESOP) commercial mechanical contractor founded in 2010 by Jason and Shaun Patnaude, each with more than 25 years of HVAC industry experience. The company operates from Essex Junction, Vermont and provides single-source HVAC, building automation, electrical, plumbing, refrigeration, and air-quality services to commercial building owners, facility managers, general contractors, and architects across Vermont, New Hampshire, and New York, operating two divisions marketed as Alliance Mechanical and Alliance Building Automation.

The company's technology foundation is multi-vendor building automation systems integration rather than proprietary software. Technicians are factory-trained and certified on Schneider Electric (exclusive Vermont partner), Johnson Controls (Authorized Systems Integrator in VT/NH/NY), Honeywell, Tridium Niagara, Alerton BACtalk, KMC Controls, and legacy platforms (Invensys IA, Barber Coleman Network 8000, Honeywell XL 5000). Services include design, installation, migration from legacy controls to modern HTML5-based platforms, DIARMF-compliant cybersecurity offerings for U.S. Department of Defense customers, HVAC laser alignment for rotating machinery, and a 24/7 emergency response capability supported by six branch offices (Essex Junction HQ, South Burlington, Clarendon, West Lebanon, Plattsburgh, Bow) and a workforce of more than 100 experienced technicians including licensed electricians.

Revenue is generated through quote-based professional services contracts across service/repair, planned maintenance, and project-based design/build and plan/spec construction delivery. Pricing is not publicly disclosed and is determined per project; commercial building owners and managers are the primary customer segment, followed by general contractors, architects, and government/education facilities (e.g., McClelland Elementary School). GTM is enterprise field sales with 24/7 phone response, complemented by an ESOP-led employer brand and direct community engagement. The company received investment from Trinity Hunt Partners in April 2023 and has not disclosed funding amounts or financial results.

Direct peers

• Limbach Holdings: Limbach Holdings is a publicly traded specialty mechanical contractor delivering HVAC, plumbing, building controls, and 24/7 service across the U.S. It is the closest scaled analogue to Alliance's single-source mechanical services + building automation model, with a similar design/build, plan/spec, and recurring service mix.
• H.T. Lyons / H.T. Lyons Engineering Services: H.T. Lyons (a Service Logic Mechanical company) is a commercial HVAC, building automation, and mechanical services contractor operating in the Mid-Atlantic/Northeast. It competes directly for commercial mechanical service, BAS integration, and design/build work in adjacent Northeast markets to Alliance's Vermont/New Hampshire footprint.

Broad incumbents

• Comfort Systems USA: Comfort Systems USA is a national mechanical contractor group operating across HVAC, plumbing, building automation, and electrical through regional operating companies. It directly competes with Alliance on commercial mechanical service and installation but at meaningfully larger scale and broader geography.
• EMCOR Group: EMCOR Group is a Fortune 500 provider of mechanical and electrical construction, building services, and industrial services through subsidiary mechanical contractors. Its United States mechanical building services segment competes for the same commercial HVAC, BAS, and FM contracts Alliance pursues, but at substantially greater scale and enterprise reach.
• APi Group: APi Group is a global specialty services holding company with extensive mechanical, HVAC, life safety, and energy service operations. Its safety/security and specialty services segments are highly comparable to Alliance's commercial mechanical/HVAC offering, though APi operates at materially larger scale.
• Trane Technologies: Trane Technologies is a global climate innovator manufacturing HVAC equipment and operating a North American Trane Commercial service network. Alliance competes against Trane Commercial for service contracts on Trane equipment while partnering with adjacent BAS vendors, making Trane the closest OEM-affiliated incumbent benchmark for commercial HVAC service.
• Carrier Global: Carrier Global is a leading HVAC manufacturer that also offers commercial service, modernization, and building automation through its Carrier/Automated Logic brands. Carrier competes on equipment replacement, retrofits, and BAS integration — overlapping with Alliance's mechanical services and BAS work.
• Johnson Controls: Johnson Controls is a global building technology company supplying HVAC equipment, controls (Metasys, Facility Explorer), and integrated building automation. Alliance is a JCI Authorized Systems Integrator, making JCI simultaneously a partner and the most relevant incumbent competitor for BAS and HVAC service work in VT/NH/NY.

Others

• Schneider Electric: Schneider Electric is Alliance's exclusive Vermont building automation partner and a global supplier of EcoStruxure BMS, power, and energy management. While primarily a technology supplier/enabler rather than a direct competitor, Schneider sometimes bids directly on large federal and enterprise integration projects where Alliance acts as the local integrator.

Regional players

• Peterson Service Company: Peterson Service Company is a mechanical services contractor in the Northeast providing commercial HVAC, plumbing, electrical, and energy services. It mirrors Alliance's single-source regional mechanical contractor model in adjacent New England geography.
