Solar by day. Electric by night. Savings all year.
Taking a step to conserve energy with a SunSource Comfort System can save you
hundreds of dollars on your utility bills every year.
A SunSource Comfort System makes use of all available solar energy to reduce
electric consumption—full sun is not a requirement. On days with limited sun
exposure, the SunSource Comfort System continues to operate efficiently using
metered electricity provided by your power company.

Air Conditioning
**
That means no matter where you live, the SunSource Comfort System is a viable
renewable energy solution that can make a positive change in your home
environment…and global environment.
54%
Studies have shown that more
than half of your household
energy use goes to heating
and cooling.**

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.ꢀ0 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.
Conserves energy while preserving
the environment
The SunSource heat pump is designed with a two-stage
scroll compressor that uses Rꢂ10A refrigerant, which meets
the U.S. Environmental Protection Agency’s standards
for ozone and environmental safety.
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
XPGꢀ0 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.
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.
