HVAC Energy-Efficient Products

As a four-time winner of the ENERGY STAR® Manufacturing Partner of the Year award—and the first and only winner in the heating and cooling industry—Lennox offers a complete selection of high-efficiency systems that can save you as much as 20% annually on your total energy costs.* These systems help keep you comfortable year-round and contribute to a cleaner global environment.

Ultimate Comfort

The Ultimate Comfort System™ offers unprecedented efficiency even in extreme hot or cold. It uses Precise Comfort™ technology to adjust heating or cooling in increments of 1%, so your home is filled with perfectly conditioned air, using the least amount of energy possible. The Ultimate Comfort System is so innovative, it can use SunSource® solar modules to harness the sun's power.

Cutting-Edge Cooling

The XC25 is the world's first residential air conditioning unit rated at more than 25.00 SEER. Compared to conventional single-stage systems, it can substantially reduce your monthly utility bills. Plus, like many Lennox cooling systems, it uses the chlorine-free R-410A refrigerant, which meets the stringent guidelines set forth by the U.S. Environmental Protection Agency.

High-Efficiency Heating

Exclusive Precise Comfort™ technology makes the SLP98V among the most efficient home heating systems you can buy. Like the XC25, this furnace can significantly reduce utility bills.

Solar Ready Heating and Cooling

SunSource Home Energy System

One source of renewable energy to consider is the new SunSource® Home Energy System, a remarkable innovation that uses select air conditioners and heat pumps from the Dave Lennox Signature® Collection as a platform for a solar-powered system that generates electricity to heat and cool your home… and more. The SunSource system provides significant reductions in energy usage and utility costs, and delivers measurable environmental benefits, too.

Dual-Fuel Comfort

Another fuel-efficient option is to combine a gas furnace with an electric heat pump in a dual-fuel system. Whenever the weather becomes too cold for the heat pump to operate efficiently (at about 32˚F), the furnace provides the extra power you need to stay warm. While this home heating solution uses gas to heat your home, it does so only when necessary.

Exclusive Thermostat

Obtaining maximum energy efficiency from your heating and cooling products is now simpler than ever, thanks to the Lennox iComfort Wi-Fi® thermostat. Our most innovative and user-friendly programmable thermostat yet, iComfort Wi-Fi works with compatible products to help control utility costs year ‘round.

If you decide to replace your thermostat with an iComfort Wi-Fi or other programmable control, chances are you can recycle your old thermostat at a Lennox distribution facility near you. Learn more about disposal of mercury-containing thermostats.

Four-area Zoning

The iHarmony® zoning system directs heating or cooling to where it’s needed, while reducing it in rarely used rooms to save energy. When the iharmony system is paired with an iComfort Wi-Fi® thermostat, you can program daily or weekly schedules for up to four different zones with just a few taps of the thermostat or even your phone.

*How much energy you save depends on your local climate, the cost of utilities and gas, and the temperature setting inside your home. Source:
