It starts with pure, clean freshness that lets you breathe easier. Then, there's the silent flow of precisely heated air to every room.

Yes, perfect air may sound like a dream, but it doesn't have to be. Discover the secrets behind perfect air, right here.

Look for variable capacity to ensure steady performance

Unlike single-stage units that can only operate all the way on or off, furnaces with Precise Comfort^® variable-capacity technology have the ability to make incremental adjustments in heat and airflow. That means more even temperatures and virtually silent operation.

Choose systems that turn serious comfort into serious energy savings

Perfect air shouldn't require uncomfortably high utility bills, so look for home heating and cooling systems that make smart use of energy. Precise Comfort technology built into select units from the Dave Lennox Signature^® Collection delivers exactly the right amount of heating, using energy only when it's absolutely needed.

Take smart control of your home's heating

Gone are the days of leaving a soft bed to adjust the thermostat, or coming home to find stuffy rooms. New advances in heating and cooling controls allow you to enhance your home comfort and save energy from anywhere. With Lennox' iComfort Wi-Fi thermostat, temperature settings can be adjusted using a smartphone, tablet or laptop.

Tap into the power of zoning

Perhaps you have one area in your house that's always drafty, or a seldom-used guest room that needs little heating. With iHarmony^® zoning, you can direct air to specific areas in your home and reduce airflow to others—with just a few taps of your thermostat or even your phone. You can keep your family perfectly comfortable, while keeping your home energy efficient.

Fill your home with air that feels good – and is good for you

There's nothing like the comfort that comes with knowing the air you breathe inside your home is clean, healthy and free of contaminants. Lennox' PureAir^™ air purification system works with your heating and cooling system to clean the air in your home better than any other single system you can buy.

Bring it all together in one perfect system

Any one Lennox^® product can make your home feel cozier. Put them all together in a Lennox^® system, and you can enjoy exceptional comfort and efficiency. And with Ultimate Comfort System, Lennox' most advanced system, perfection is achieved.
