Indoor Air Quality System – Humiditrol® Whole-Home Dehumidification System

The Humiditrol® Whole-Home Dehumidification System manages the moisture in your home�s air for greater comfort and improved indoor air quality. It also helps make you air healthier by mimimizing the impact of many potential indoor pollutants.

Indoor Air Quality System – PureAir™ Air Purification System

The PureAir™ Air Purification System cleans the air in your home better than any other single system you can buy. It helps control everything from microscopic dust mites and mold spores to infectious bacteria and viruses. And it's the only indoor air quality system that safely removes and destroys odors and chemical vapors. It uses patented photocatalyic technology to filter, purify and freshen the air, and it combines these capabilities into one integrated system.

iHarmony® Zoning System

The iHarmony zoning system solves the problem of uneven or uncomfortable temperatures throughout your house, while helping you reduce energy costs.

The iHarmony zoning system makes it easy to make your home feel welcoming year-round. It allows you to change the temperature throughout the house, or change it in specific areas, with just a few taps of the thermostat or even your phone. You can keep your family perfectly comfortable and keep your home efficient, all while enjoying ultimate control and ease.

Precise Comfort™ Technology - Heating

The SLP98V gas furnace uses exclusive Precise Comfort™ technology to create an environment of perfectly heated and humidified air, and the temperature you specify is maintained with an accuracy of 1/2 degree or less.

Precise Comfort™ Technology - Cooling

The XC25 air conditioner and XP25 heat pump use exclusive Precise Comfort™ technology to create more even temperatures with lower humidity, while also reducing energy costs. Lennox Precise Comfort technology enabled by the iComfort Wi-Fi® thermostat, allows your cooling system to maintain your set temperature regardless of outside conditions by making minute adjustments to airflow and cooling.

Variable-speed furnace technology

A variable speed furnace motor uses two-thirds less electricity than a standard single-speed motor. With the energy savings you enjoy each month, your investment in a Lennox variable speed furnace will pay off.

Two-stage cooling: air-conditioning

There's cool, and there's perfectly cool. Lennox® air conditioners like the XC21 make the distinction with two-stage technology, which adjusts operating speed for a more precise temperature throughout your home.

Two-stage cooling: heat pump

Unlike typical single-stage heat pumps that operate only at full power, Lennox® heat pumps like the XP21 and XP16 can adjust heating and cooling output to match household demand. They run mostly at low stage to maximize comfort and energy savings.

How a Heat Pump Works

Ideal for warmer climates, a heat pump is an efficient choice when you want mostly cool air and heated air only on occasion. Lennox® heat pumps can also be combined with gas furnaces for ultimate comfort and energy savings.

Comfort Controls – ComfortSense® 7000 Series Touchscreen Thermostat

The ComfortSense® 7000 Series Touchscreen Thermostat controls every heating and cooling system in your home, offering precise humidity and temperature control and easy touchscreen operation.

Lennox® Ductless Mini-Split Systems

For individual rooms that are difficult to heat or cool, or multiple rooms, Lennox Mini-Split Systems are like having a dedicated air conditioner or heat pump in specific areas.

How it works
Your Lennox dealer mounts the indoor module, and connects it to the outdoor module through one small hole in the wall.
During the summer, your Lennox Mini-Split air conditioner transfers heat from the indoor module to the outdoor module, so your room stays crisp and cool.
On the other hand, if you've installed a Lennox Mini-Split Heat Pump, it will cool the exact same way during the summer, but during the winter, it will reverse the process to draw heat in, keeping your room cozy and warm.

Ductless Mini-Split Systems are an excellent choice for:

  • Home Offices
  • Sunrooms
  • Room additions
  • Bonus rooms and more

With your Ductless Mini-Split System installed, you'll enjoy consistent comfort, along with:

  • Superior energy efficiency
  • Potential qualification for Federal energy tax credits
  • And even potential utility rebates
  • All with Lennox’s commitment to innovation, quality and performance

Get comfortable anywhere, any time with a Lennox Ductless Mini-Split System, available now from your local Lennox dealer.
