Nordyne manufactures residential and light commercial heating and cooling products, branded under names such as Frigidaire, Maytag, Westinghouse, Tappan, Philco and Gibson. It also makes HVAC equipment specifically for manufactured homes under the Intertherm, Broan and Miller brands. Nordyne is a unit of privately-held NTK Holdings, and posts annual revenue of about $160 million.
Formed as International Oil Heating Co. in St. Louis in 1919, the company went public using the name Intertherm–which it still uses as one of its brand names–in 1969. Nortek Inc. purchased Intertherm and Miller (previously a part of Lear-Siegler) –now another of Nordyne's brands–before combining the two into its then renamed Nordyne subsidiary. Nordyne remained public until 2004, when Nortek decided to return the company to private ownership.
Nordyne uses Demand Flow Technology (DFT)–a mathematical approach to manufacturing developed by former Hewlett-Packard executive John Costanza–which sets Nordyne as a demand-driven operation. The company notes that it's the only heating and cooling manufacturer to be DFT-certified, which occurred in 1998. As for the lines themselves, Nordyne sells HVAC appliances and parts across several of its brand names. For residential use, these include split-system air conditioners and heat pumps, high efficiency gas and oil furnaces, packaged electric and gas/electric heating and cooling units, as well as a variety of air comfort accessories. For the light-commercial market, Nordyne products include a full line of split-system and packaged air conditioning, heat pump, and gas/electric units up to 15 tons.
All warranties are manufactured-backed and not third-party administered. The company's warranty is based on the particular product but range from one to 10 years, depending on the model and purchase date. However, parts purchased individually from Nordyne direct come with a standard one-year warranty.
