About First Co.: American-Made HVAC Excellence Since 1966

First Co. is a privately held, family-owned HVAC manufacturer headquartered in Dallas, Texas. Founded in 1966, the company set out to give the rapidly growing HVAC industry an independent, domestic source of quality fan coils — and has since grown into one of the most respected names in heating and cooling. With a sprawling manufacturing campus in Dallas and a workforce that collectively brings over 150 years of combined industry experience, First Co. has delivered more than 5.5 million units to customers across North America.

What sets First Co. apart is a steadfast commitment to American-made ingenuity and continuous improvement. The company's engineering philosophy centers on building systems and components that are rigorously tested before leaving the factory floor, ensuring every product meets demanding performance and reliability standards. This dedication has made First Co. a go-to supplier for residential, multi-occupant, and commercial HVAC applications alike — from hotels and condominiums to single-family homes.

First Co. Product Lines

First Co.'s catalog spans fan coil units, air handlers, single package vertical units, water source heat pumps, and the components needed to keep them running. The company's ECO-Series, for example, consists of compact through-the-wall units capable of delivering conditioned air from a single unit to multiple rooms — a hallmark of the innovative thinking that has defined the brand for decades. Replacement parts and components are engineered specifically for First Co. systems, eliminating guesswork and ensuring seamless compatibility.

For technicians and building managers sourcing replacement components, First Co. offers a comprehensive parts ecosystem. HVAC Control Modules serve as the electronic brain of a unit, managing operational sequencing and zone control functions. The brand's HVAC Blower Motors are designed to precise speed and airflow specifications to match original equipment performance. A/C Evaporator Motors keep the evaporator fan spinning reliably for consistent heat transfer and cooling. Complementing the motors, HVAC Blower Motor Wheels are matched to First Co. blower assemblies for balanced, efficient airflow. And for full coil replacements, First Co.'s Evaporator & Condenser Coils are built with high-efficiency copper tube and aluminum fin construction to maximize thermal performance.
