About Armstrong Air
Armstrong Air is a residential heating and air-conditioning brand of Lennox's Allied Air Enterprise business, sold through independent wholesale distributors in the US and Canada rather than direct to dealers like Lennox itself. Lennox's 2001 10-K said the brand had a traditional base in the Northeast and Central United States and that the company planned to expand it into the South and West. In 2001 Lennox's Advanced Distributor Products division also built coils and air handlers under the Armstrong Air name.
