What W. L. Gary Company, Inc. does

W. L. Gary Company, Inc. is a privately held, family-owned mechanical contractor headquartered in Washington, D.C., operating continuously since 1895 and currently in its fourth generation of Gary-Greer family leadership. The company provides integrated HVAC, plumbing, and mechanical construction services to commercial, industrial, healthcare, educational, hospitality, and mission critical facility customers across the Washington, D.C., Maryland, and Northern Virginia metropolitan area, with project sizes historically ranging from $4M to $19M.

The company's service portfolio spans three integrated lines: HVAC service and maintenance (including 24/7 emergency response, VRV/VRF systems, chillers, boilers, CRAC units, and mission critical HVAC), plumbing (backflow prevention certification, hydro-jetting, video inspection, grease traps, drain/sewer cleaning), and construction (design-assist, design-build, plan and spec, and BIM-based 3D coordination). Technology capabilities center on 3D BIM coordination and shop drawing generation, a Hyattsville, MD fabrication shop for pre-fabrication, hydro-jetting and video inspection equipment, and certified partnerships with Daikin, LG, and Mitsubishi for VRV/VRF systems. ERP systems unified across construction, service, and accounting in 2014.

The business model combines project-based construction revenue (largest individual contracts reaching $19M) with subscription-style recurring service maintenance agreements covering HVAC, plumbing, backflow certification, and mission critical systems. Customers are reached via direct enterprise field sales targeting GCs (HITT Contracting, Whiting Turner, Gilbane, Clark Construction, Forrester Construction) and direct relationships with institutional end-customers in healthcare (Washington Hospital Center, Calvert Memorial, Civista), education (Georgetown, George Mason, American University), and data center operators. Pricing is quote-based on commercial projects with limited disclosed residential pricing tiers.
