The Ultimate System for Perfect Air.

The Ultimate System for Perfect Air.

The Ultimate Comfort System™ combines the best of the Dave Lennox Signature® Collection to create an unprecedented whole-home comfort system that seamlessly and intelligently works together to stay finely tuned to your customer’s home while delivering consistently clean, perfect air.

This is Seamless Precision.

Here’s how the Ultimate Comfort System handles the most common heating and cooling issues.

Hot here? Cold there? Hot here? Cold there?

Forget temperature swings and having the weather dictate humidity. This system is in constant communication with itself to deliver clean, perfect air and maintain your home’s ideal temperature and humidity level with pinpoint accuracy. Period. And with iHarmony zoning, you can optimize and personalize your air throughout different sections of your home. That way, the only way your air feels is how you want it to feel.

Overworked system running up your bills? Overworked system running up your bills?

More efficient than anything the industry has ever seen, this system is in constant communication with itself to deliver nothing short of consistently perfect air. Including a standard-setting furnace that boasts a 98% efficiency rating—that means it essentially converts every last bit of energy it uses into heating and cooling the home—and an air conditioner that achieves an efficiency rating of up to 28 SEER. Best of all, the energy saved is as healthy for your wallet as it is for the environment.

Unbearably noisy? Unbearably noisy?

Hear that? Of course, you didn’t. Even with all of its impressive power, this system has been engineered to run at variable capacity and variable speed to drastically minimize the sound of air kicking on or off inside the home. Add in a special sound-dampening system to absorb outdoor noise and you can be assured it all operates at a noise level that is, quite simply, unheard of.

Sniffling and sneezing? Sniffling and sneezing?

From dust, pollen and dander to mold and germs to odors and chemical vapors, indoor air carries all sorts of unwanted, health-affecting contaminants. Fortunately, the unparalleled PureAir™ S reduces them with thorough filtration and a powerful air purification technology. Not only will it remove 99.9% of allergens and 90% of virus-sized particles, it is the only single system to combat all three major types of indoor pollutants.

The Ultimate System for Perfect Air.

From heating and cooling to air purification and effortless controls, every component of the Ultimate Comfort System works seamlessly together to deliver nothing short of perfect air.

Unlike most smart thermostats, the iComfort S30® is more than a temperature regulator. It’s the command center for your entire system, with the incredible ability to monitor sensors in all of your equipment to react, diagnose, and troubleshoot. For added assurance, installers can be in constant contact with your homeowners to ensure proactive responses. No more downtime or guesswork. Only solutions that keep your system running as perfectly as it should be.


Of course, homeowners can also use their iComfort S30 or the Lennox app to schedule and set away modes, adjust and maintain temperatures, ensure ideal humidity levels, optimize comfort in your home’s zones, and more.
