A SMART CHOICE FOR EFFICIENCY AND EXCEPTIONAL OPERATION, EVEN IN THE COLDEST CLIMATES.
BUILT FOR LIFE. YOURS.

Delivering consistent comfort
and peace of mind
Since 1928, we’ve been providing homeowners
with reliable, well-built heating and cooling products
that make life easier and more comfortable.
Thoughtfully designed, our AirEase™line of gas
furnaces offers an impressive array of technology
that makes them extremely quiet, dependable and
energy efficient. So you can enjoy peace, quiet
and comfort every day of every year.
HVAC experts you can trust
Your comfort is our priority. Your AirEase Dealer will
take the time to understand your comfort needs.
They know you want the best performance, value
and dependability from your heating system, and
they have the products and expertise to satisfy these
demands. That means you can rely on your AirEase
Dealer to help you to find exactly the right comfort
solution for your home and your lifestyle.

Creating the
ideal environment.
Choosing the right heating and cooling system for your home environment is a big decision.
Your AirEase™Dealer can help you create the right system for your home comfort needs. To
help you make the best and smartest system choice, here are a few things to consider:
Efficiency
It’s pretty simple. A high-efficiency system helps lower your monthly
utility bills. Efficiency is measured in AFUE (Annual Fuel Utilization
Efficiency)—the higher this number, the greater the efficiency.
Replacing an older unit with a 90%+ AFUE unit or higher can
increase performance and start saving you money.
Reliability
You can always count on your AirEase unit. Our EHX™
Technology and unique burner design work together to deliver
premium performance and even heat exchange, which will
extend the life of your furnace.
Air Quality
Where you live matters. Your family’s sensitivity to a host of
natural and man-made allergens means enhanced air quality is
all the more critical in your home. And don’t forget humidity levels
when you’re considering the ideal system for year-round comfort.
Peace of Mind
More control over your comfort—that’s our commitment to you.
You can see it in our craftsmanship and technology—like our
proprietary Comfort Sync®controls, which allow you to easily
monitor your unit’s performance and enjoy maximum comfort in
your home.
Noise Reduction
Comfort and performance also include quiet operation of
your system. Enjoy quieter start-up and operation with our
Quiet Combustion™Technology.

How It Works
Furnace System Basics
The most common type of system pairs
an interior gas furnace with an exterior
air conditioner. Furnaces can also be
paired with a heat pump, which is then
called a dual-fuel system. Matching
your furnace with a compatible
AirEase™air conditioner or heat pump
will generate optimum efficiency and
ideal system performance.
Single-Stage: A reliable, single-stage
gas valve provides a consistent gas flow
to maintain temperature.
How gas valves affect
temperature control
Modulating: The gas valve constantly
adjusts heating capacity to create even
temperatures throughout your home,
while also being the most efficient.

Two-Stage: Two-stage gas valve
provides a boost in heating, when
needed, to enhance comfort.

1. When it gets cold inside your home, your thermostat
automatically activates your gas furnace to compensate.
2. The burners ignite the gas and create warm air in the
heat exchanger.
3. The blower turns on and forces the warm air throughout
your home via ducts.
4. Warm air is circulated throughout your home until the
desired temperature is achieved.

Advanced Heat Exchanger:
Made from stainless steel for maximum strength and
crimped rather than welded, AirEase heat exchangers
are highly resistant to thermal fatigue and other stresses
caused by repeated heating and cooling. During the
testing process, they are subjected to temperatures that
far exceed normal operating ranges, to ensure they will
stand up to decades of use.
EHX™Technology:
Every AirEase furnace is engineered and built with
EHX™Technology, a patented design that eliminates the
hot spots that can shorten furnace life. EHX Technology™
makes heat exchangers more durable, and with its
advanced airflow system, more air contacts the heat
exchanger surface area for greater heat transfer into the
home, enhancing efficiency and comfort.
Modulating Gas Valve:
Highly precise system combines a modulating gas valve
with variable-speed technology** to deliver consistent
temperatures while saving energy. It constantly varies
heat and airflow in increments as small as 5%,
responding to outdoor conditions and household
comfort needs. By comparison, a typical single-stage
furnace operates at full heating capacity every time it
cycles on.
Noise Reduction:
Insulated cabinet prevents loss of warm air, while
reducing noise from the motor.
Quiet Combustion™Technology:
Uses a lower Btu input per burner ensures quieter
start-up and operation.
Comfort Sync®Control Panel:
Our Pro Series™communicating-enabled models provide
benefits for installation and maintenance diagnostics,
as well as full voice and app-control and precision
zoning for complete comfort.***
