When was Nortek Global HVAC founded?

The company traces to 1919, when it was founded in St. Louis as the International Oil Heating Company. It operated as Nordyne for decades before rebranding as Nortek Global HVAC in 2022.

The company traces to 1919, when the International Oil Heating Company was founded in St. Louis, Missouri, to build oil burning heaters. The original pitch was practical: help the city reduce the coal smoke pollution then covering it by offering cleaner oil heat for homes.

Through the mid 20th century the company evolved through names and ownership changes, eventually becoming Nordyne, a manufacturer of heating and cooling systems under multiple brand labels. Nordyne built its position on licensed brands, producing HVAC equipment sold under names like Frigidaire, Maytag, and Westinghouse that consumers recognized even though a different company made the actual units.

The corporate parent was Nortek Inc., a diversified building products company. Madison Industries, the Chicago based holding company controlled by Larry Gies, acquired Nortek in a transaction completed around 2016 for approximately $2.8 billion, taking the business private.

In 2021 Madison reorganized its air management businesses, and the HVAC operation was relaunched as Nortek Global HVAC in 2022 with a refreshed brand identity while keeping the same O'Fallon, Missouri manufacturing and engineering base.

The latest chapter is Rheem ownership. Rheem announced in September 2024 that it would acquire Nortek Global HVAC from Madison, completing the deal on October 7, 2024. NGH now operates within Rheem's Global Air division, giving Rheem expanded manufacturing capacity and a deep manufactured housing presence.
