Nordyne furnace owner and instruction manuals are available as PDF files from a technical support repository attached to, but not directly navigable from, the company's main website. Technical literature for the company's products are available from the Nordyne University website, requiring registration for professional HVAC technicians.
The Nordyne University website is reached from the Technical Literature link on the main company website, as of 2015, located next to the Distributor Login.
Nordyne also maintains a residential literature archive. It features technical specifications, installation instructions, wiring diagrams and replacement parts lists for HVAC products formerly sold by the company. Within this archive, units are categorized by function, series and efficiency ratings. Furnaces are grouped by annual fuel utilization efficiency ratings, while air conditioners are sorted by seasonal energy efficiency ratings.
In January 2015, Nordyne changed its name to Nortek Global HVAC. The company, as a subsidiary of the multinational conglomerate Nortek Incorporated, manufactures, sells and supports products under licences with legacy brands such as Westinghouse, Frigidaire, Broan, Maytag, NuTone and Tappan. It has been in business for over 95 years and is, as of 2015, headquartered in the United States. A national headquarters is located in O'Fallon, Missouri, while the global headquarters is found in Miami, Florida. Three manufacturing and distribution facilities are based in Tennessee and Missouri.
