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 home and deliver consistently clean, perfect air.
Meet the Most Efficient System Ever.
The Ultimate Solution.
Here's how the Ultimate Comfort System handles the most common heating and cooling issues.
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?
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 an efficiency rating up to 99%—that means it essentially converts every last bit of energy it uses into heating and cooling the home — and cooling products that achieve efficiency ratings 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?
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?
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™ Sreduces 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.
This is Seamless Precision.
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.

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, it keeps in constant contact with your installer to ensure proactive responses. No more downtime or guesswork. Only solutions that keep your system running as perfectly as it should be.
Of course, you can also use your 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.

Questions?
The equipment you select for your system will be determined largely by the climate where you live. Warmer climates may include a heat pump and an air handler, while colder climates typically include an air conditioner and a furnace. Yet, a moderate climate may call for a dual-fuel system. A Lennox Comfort Advisor is trained to help you plan a system that will meet your unique needs and solve your specific comfort issues. For more tips, read: Building your Complete System: The Smarter Way to Better Comfort.

By replacing your entire system, rather than just a single component, you get equipment that’s been designed to work together. Because of this compatibility, you’ll enjoy greater energy efficiency and optimized comfort. With the continuing advancement of home comfort technology, equipment is becoming more energy efficient. A new system may offer you substantial energy savings even if your current system is only a few years old.

Start with our dealer locator to find a Lennox dealer near you. Our Premier Dealers are trained to build a solution to meet your needs, have Ultimate Comfort System product knowledge and are experts in equipment installation. Prior to a visit from a Comfort Advisor, we recommend that you spend some time asking yourself ‘How do I want the air in my home to feel?’ and ‘What Does Perfect Air Mean to Me?’. Identifying these needs and goals will help your Comfort Advisor recommend a system that delivers Perfect Air.
A Lennox dealer can give you the best estimate of cost for a HVAC system to meet your needs. Your dealer will evaluate the size and age of your home, your home’s design, layout and ductwork and the local climate. These inputs allow a Lennox dealer to recommend your ideal system configuration, calculate the installation effort and provide you with a quote.
Some things to consider:
- Your heating and cooling system accounts for around half of the energy your home uses each month.
- From financing options to rebates and federal and local tax credits, investing in a new HVAC system is within your reach.
- Our energy savings calculator can help you estimate your savings over the lifespan of your HVAC system.
