True comfort is Precise Comfort® - Even on the most humid days, Lennox Precise Comfort® technology keeps temperatures exactly where you set them, using only the energy that’s needed.

Technologies and efficiencies beyond compare!
SunSource® technology allows Lennox solar-ready heat pumps to reduce your heating and cooling costs by up to half. When paired with the iComfort® S30 thermostat, Lennox heat pumps deliver unparalleled efficiency, whether you’re home or away.

Great savings happen when two energy sources work together!
When you combine a compatible Lennox heat pump with an efficient Lennox furnace, you can create an energy-saving dual-fuel system. The heat pump functions as both a heating and cooling system, reducing gas fuel consumption. On extra-cold days, the gas furnace becomes the primary heat source, ensuring maximum comfort is maintained.

Stay comfortable—and asleep.
Peace and quiet are just as much a part of the perfect environment as temperature and humidity. That’s why many Lennox heat pumps offer SilentComfort™ technology that produces some of the lowest noise levels in the industry.

Lennox Air Purifier


From the industry’s most effective air purifier to the #1 rated filtration system*, there's an innovative solution you can feel good about.

Whole-home solutions for complete peace of mind.
Healthy Climate® air purification and filtration systems are designed to work with your central heating and cooling system. They improve the air throughout your entire home—not just in individual rooms—without producing ozone, a known lung irritant*.

The most effective way to improve your air!
The PureAir™ air purification system is the only single indoor air quality system to combat all three classes of contaminants. Allergy-aggravating particles such as dust, pollen and pet dander. Mold and germs that grow and reproduce in damp places, such as basements and crawlspaces. Odors and chemical vapors from paints, cleaning supplies and additives used in carpeting and furniture.

Multiple technologies working together in one powerful system! PureAir™ reduces and destroys contaminants with hospital-grade filtration and a powerful air purification technology called photocatalytic oxidation (PCO).

Other smart solutions for a healthier home...The Carbon Clean 16® media air cleaner is the #1 rated, professionally installed, whole-home filter as rated by a leading consumer magazine*. A Bright Solution For Controlling Germs.  Healthy Climate germicidal lights use intense rays of ultraviolet light to control and kill contaminants.


A difference you can truly feel.

Too much moisture in your home’s air can make it feel heavy and sticky, and can even promote the growth of mold and mildew. A Humiditrol® whole-home dehumidifier works to reduce humidity levels and create a healthier, more comfortable home.

Energy savings you can feel good about.
Dehumidified air feels cooler, so you can set your thermostat at a higher temperature and still feel comfortable. In fact, for every two degrees you raise the temperature during the summer, you can save between 5% and 7% on your cooling bill.

Patently better performance.

The Humiditrol whole-home dehumidification system uses patented technology to remove excess humidity from your home. Because it’s designed specifically for use with Lennox® cooling equipment, there are no tanks to empty and no cords to trip over—just perfectly balanced air flowing to every room.

Controls humidity without producing ozone
Unlike some portable indoor air quality systems on the market, Humiditrol® makes your home healthier without producing ozone, a toxic gas that can irritate the lungs*.
