Nortek delivers a breath of fresh air. The company makes and distributes residential and commercial air conditioning and heating systems (HVAC), residential ventilation products, and home technology products. In addition to HVAC systems, Nortek's wares include range hoods and other ventilation products, indoor air-quality systems, lighting controls, and home entertainment and security system equipment. Products, which are sold primarily in North America and Europe, bear the Nortek name, along with other brands including Broan-NuTone, as well as such licensed names as Frigidaire and Maytag. Nortek and its subsidiaries filed for Chapter 11 bankruptcy in 2009, but quickly emerged.
