First Co.

First Co. is an American HVAC manufacturer headquartered in Dallas, Texas, that has served the multi-occupant (multi-family, hospitality, and commercial) heating and cooling market since its founding in 1966. The company describes itself as American-made and family-owned, and states that it has delivered over 5.5 million units from a 900,000-square-foot manufacturing base in Dallas. Its product portfolio centers on chilled water fan coils, water source heat pumps, and related equipment engineered for space-constrained, multi-occupant buildings such as apartments, hotels, dormitories, and high-rise residential projects. First Co.'s catalog includes ceiling fan coils, low-height fan coils, multi-position fan coils, wall-mount fan coils, single-package vertical units, through-the-wall split units, and accessories. Its newer lines include the UCS Series electric heat and hydronic heat cabinets, the Cool-Pak Series heat pump with variable-speed inverter and electronic expansion valve, the WC Series (WCX2/WCR2) compatible with R-32 and R-454B low-GWP refrigerants, and the RR Series with an integrated Energy Recovery Ventilator. The company also offers a Quote-ify online configure-price-quote tool and legacy/obsolete product lookup resources for replacement planning. First Co. markets to developers, contractors, architects, engineers, distributors, and hospitality operators. Its stated positioning emphasizes quality, reliability, continuous improvement, advanced testing, and tailor-made solutions supported by a long-tenured customer service team. The company remains privately held and family-owned, with the Nation family identified in its own materials as the owning family.

First Co. was founded in 1966 and has since operated as a family-owned American manufacturer of heating, ventilation, and air conditioning equipment. From its base in Dallas, Texas, the company focused on the multi-occupant segment of the HVAC market — buildings such as apartments, hotels, dormitories, and high-rise residential towers where individual room-level comfort and space efficiency are critical. Over six decades the company reports having delivered more than 5.5 million units from a 900,000-square-foot manufacturing facility in Dallas. The company's product evolution tracks the needs of multi-occupant construction. Its core lines have long included chilled water fan coils and water source heat pumps in configurations such as ceiling, low-height, multi-position, and wall-mount fan coils, as well as single-package vertical units and through-the-wall split units. These products are designed to fit tight mechanical spaces while providing reliable room-by-room conditioning. In recent years First Co. has introduced updated and expanded lines. The UCS Series added electric heat and hydronic heat cabinets with galvanized steel, fully insulated construction, wall-mount flexibility, and capacities up to 10 kW electric heat and 55,000 BTUH hydronic. The Cool-Pak Series brought a space-constrained heat pump with variable-speed inverter and electronic expansion valve for optimized performance. The WC Series (WCX2/WCR2) was updated for compatibility with R-32 and R-454B low-global-warming-potential refrigerants, reflecting the industry's transition to lower-GWP refrigerants. The RR Series added an integrated Energy Recovery Ventilator to deliver fresh outdoor air, improved humidity control, and lower operating costs without increasing system size. The company also launched Quote-ify, an online configure-price-quote tool, and maintains legacy and obsolete product lookup resources to help customers find replacements for older models. Throughout its history First Co. has emphasized American manufacturing, engineering excellence, advanced testing, and customer service. Its own materials note that many team members have been with the company for over 30 years, and the company identifies the Nation family as its owning family. First Co. remains privately held and active, celebrating its 60th anniversary in 2026.
