Lennox Industries

The Idea House features the latest high-efficiency, Energy Star–rated air-conditioning/condensing units and furnaces by Lennox. The Lennox Harmony zoning system divides the house into sections so heating or cooling can be delivered only where it is needed. Programmable digital thermostats allow for precise climate control. New ultraviolet germicidal lights kill airborne germs, and electronic air cleaners remove dust, dirt, and pollen. The house also features two Lennox Elite direct-vent gas fireplaces—one at each end of the great hall. (800) 953-6629 or www.lennox.com.
