The Wall Street Journal broke the news yesterday that United Technologies Corp. is in talks to possibly acquire Nortek, Inc. Nortek is best known in our industry as the parent company of Core Brands, a collection of several prominent lines – such as Niles, Elan, SpeakerCraft (and others) – that are focused largely on the custom integration business, but also produces commercial and residential HVAC and air handling equipment. United Technologies is a large conglomerate with diversified holdings such as Pratt & Whitney jet engines, Otis elevators, and Carrier air-conditioning equipment.
