Addison HVAC LLC, founded in 1949 in Addison, Michigan, has been at the forefront of innovation in the HVAC industry for over seven decades. Initially starting as a manufacturer of refrigerant systems for vending machines, the company quickly pivoted in the early 1950s to residential air conditioning—capitalizing on the post-World War II housing boom. A major breakthrough came with the invention of a split system design that revolutionized how cool air was distributed in homes, making central air conditioning more affordable and accessible.
Through the 1950s and 60s, Addison expanded significantly by adding manufacturing capabilities and acquiring technologies such as heat pumps. This strategic initiative allowed the company to provide cutting-edge solutions, including the first commercially available Dedicated Outdoor Air System (DOAS) in 1963. As demand for residential comfort products grew, Addison solidified its reputation, notably by developing the WeatherKing line for warmer climates.
In 1990, Addison shifted production efforts towards commercial HVAC solutions and built a state-of-the-art facility in Orlando, Florida. This transition marked a renewed focus on innovative energy-efficient products. Today, Addison HVAC is known for its high-performing DOAS products, including the PR Series and the compact AK Series, designed to ensure optimal indoor air quality and comfort.
Now a member of Madison Industries, Addison HVAC is aligned with a mission to foster safer, healthier, and more productive indoor environments. Their commitment to innovation and quality manufacturing is encapsulated in what they call 'The Addison Advantage.' With a rich history and continuous advancements in technology, Addison HVAC is poised to lead the industry well into the future.
