What Custom Aire does

Custom Aire Mechanical Contracting & Service is an employee-owned commercial HVAC mechanical contractor founded in 1978 and headquartered in Grand Forks, North Dakota, with a second office in Bismarck. The firm delivers design-build, design-assist, and plan-and-spec HVAC contracting for commercial buildings, complemented by an in-house custom sheet metal fabrication shop, hydronic heating and light commercial plumbing, geothermal and VRF system installations, BACnet building automation integration, and retrofit services. Its service portfolio spans educational, healthcare, government, hospitality, fitness, multi-family housing, retail, and restaurant facilities across North Dakota and adjacent Minnesota, with documented customers including McDonald's, Sanford Broadway Clinic, the University of North Dakota Gorecki Alumni Center, Choice Health & Fitness, AgCountry Farm Credit Services, and the ICON Sports Center Arena.

The company's revenue model combines one-time project installation revenue with recurring service contracts structured as Energy Savings Maintenance Agreements (ESMA) at Basic, Standard, and Custom frequency tiers, plus 24/7 emergency dispatch. Go-to-market is direct enterprise field sales through relationships with developers, general contractors, and facility managers, with the company acting as either prime mechanical contractor or trusted subcontractor. Pricing is quote-based and project-specific; the company does not publish rates. Auxiliary revenue streams include custom sheet metal fabrication (captive and potentially third-party) and hydronics/plumbing work on light commercial projects.

Custom Aire has been an Employee Stock Ownership Plan (ESOP) company since 2011, building a long-running talent pipeline through a U.S. Department of Labor-approved four-year Sheet Metal Apprenticeship Program with NCCER curriculum. The firm is led by President Scott Boettner and Vice President Randy Boettner, sons of founder Dale Boettner, with a stated staff of approximately 50 employees as of 2021. The company holds multiple Associated Builders and Contractors Excellence in Construction awards and has delivered LEED-certified projects, and operates active social, blog, and career-fair channels primarily for recruitment and regional brand presence.
