Higher efficiency plus superior comfort with less noise.

Now it’s possible for you to reduce the environmental impact of your home’s heating and cooling system without sacrificing your comfort. With efficiency ratings of up to 18.20 SEER and 9.70 HSPF***, Lennox’ SunSource™ heat pump takes heating and cooling technology to new heights with help from renewable solar power.

Optimized for use with the Humiditrol® whole-home dehumidification system

As part of a complete comfort package, the Humiditrol system delivers a level of humidity control never before available. Less moisture in the air not only feels better, it improves overall indoor air quality, too.

What a difference quiet makes

The SunSource heat pump is engineered with Lennox’ exclusive SilentComfort™ technology for quiet performance day in and day out. A patent-pending fan design, two-stage operation and an insulated compressor compartment also help keep sound at a minimum.

Choosing an ENERGY STAR® product like the XPG20 SunSource™ Comfort System can help you improve comfort and save energy costs. You may also be able to qualify for utility rebates and

tax credits. By creating a more efficient home environment, you are contributing to a cleaner global environment.

Conserves energy while preserving the environment

The SunSource heat pump is designed with a two-stage scroll compressor that uses R410A refrigerant, which meets the U.S. Environmental Protection Agency’s standards

for ozone and environmental safety.

Reducing your carbon footprint—one step at a time

Every SunSource heat pump will offset 376 pounds of CO2 per year. That’s the equivalent of planting seven mature trees, or carpooling to work one day each week. If thousands of people joined in, the change would substantially reduce environmental emissions.

Proper sizing and installation of equipment is critical to achieve optimal performance. Split system air conditioners and heat pumps must be matched with appropriate coil components to meet Energy Star® criteria. Ask your Lennox dealer for details, or visit www.energystar.gov.

***SEER and HSPF are for operation without solar power input.
