Home Comfort System

Also called a split system or an HVAC system, a home comfort system is basically comprised of an indoor unit, outdoor unit and a thermostat. It often includes an indoor air quality system, too.

How It Works System

Ultimate Comfort System™

Imagine pure, clean freshness that lets you breathe easier. The silent flow of air to every room. Temperatures that stay exactly where you want them. The Ultimate Comfort System™ makes it all possible. Simply put, it’s the most advanced, most efficient, most capable heating and air-conditioning system ever created.*

Dual-Fuel System

A dual-fuel system uses two energy sources—an electric heat pump and a gas furnace—to provide the ideal combination of efficiency and comfort. The system seamlessly alternates between gas and electricity, depending on outdoor conditions.

How It Works Packagedunits

Packaged System

If your home is built on a crawlspace, instead of a basement, a Lennox packaged unit is an ideal choice for efficient home comfort. It contains all the quality components of a traditional Lennox heating and cooling system in a single compact unit.

Mini-Split System

When only certain rooms need heating and cooling, Lennox mini-split systems provide a smart, flexible solution. Maybe you have a sunroom that’s a little too warm, or a room addition that isn’t connected to your ductwork. A mini-split system can address comfort issues in each of these rooms, without a complicated installation.

Indoor Air Quality System

Indoor air quality products such as Healthy Climate® air cleaners and humidifiers work with your heating and cooling system to improve the air throughout your entire home, not just a single room. They can help with common air issues ranging from allergens and dust to humidity imbalances.

Zoning System

A Lennox zoning system allows you to change the temperature throughout the house, or change it in specific areas. It helps do two very important things—enhance your comfort and lower your energy bills.
