Lennox^® gas furnaces are among the most efficient heating systems you can buy. Energy-saving technologies like variable-speed motors also enhance comfort, creating the perfect balance of temperature and humidity in every room of your home.

Built to exacting standards with the highest-quality components, a Lennox^® oil furnace is an ideal choice for keeping your home warm and comfortable.

Variable-speed models maximize performance and efficiency by precisely controlling the flow of air throughout your home.

A typical comfort system is made up of an air conditioner and a furnace, plus a thermostat.

If you live in a warm climate where high heat is a problem year round, a Lennox^® air conditioner and matching air handler can provide the comforting relief you need. The air conditioner efficiently cools the air, and the indoor air handler moves it throughout your home.

A variation on the traditional split system, this option pairs a heat pump with an air handler. The heat pump does the job of cooling and heating your home, while the air handler moves the conditioned air throughout your home.

For the best combination of comfort and energy efficiency, a Lennox^® heat pump can be combined with a gas furnace in a dual-fuel system.
