CRAFTSMANSHIP THAT MEETS EXACTING ARMSTRONG AIR STANDARDS -- AND THE EXPECTATIONS OF HVAC PROFESSIONALS.
THE PROFESSIONAL'S CHOICE

A legacy of craftsmanship and commitment
Our 80-year history is built on the foundation of strong products and even stronger dedication to excellence. The Armstrong Air® full line of air conditioners is the perfect example of what happens when you set out to be the best. Quiet, energy efficient and made with pride by people who know quality, Armstrong Air units represent the premium choice of HVAC professionals throughout North America.
Expert guidance every step of the way
Choosing the right HVAC professional is just as important as the air conditioner you're buying. Going with an Armstrong Air Dealer means working with a true HVAC professional. You can be confident knowing their knowledge and expertise will help you make the right decisions on all your HVAC needs.They'll also help ensure your system operates at maximum performance for years to come.

Helping create your environment, your way.
At Armstrong Air, creating the perfect system for you is our first priority. We recognize that buying a new cooling system is a big decision. Having all the facts, and some professional advice, can help you select the system best suited for your home and your family's needs. When selecting a unit, it's important to remember that everyone's needs are different. What's most important to you and your family? 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 SEER (Seasonal Energy Efficiency Ratio) and the higher the number, the greater the efficiency. Replacing an older unit with a 14 SEER or higher unit can increase performance and start saving you money immediately.

Reliability You can always count on your Armstrong Air unit.Technology developments such as MHTTM and OmniguardTM, plus other advanced-design features, work together to deliver premium performance and extend the life of your air conditioner.

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.

More control over your comfort--that's our commitment

to you. You can see it in our craftsmanship and technology--

like our proprietary Comfort SyncTM 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 reduced operating noise with select models featuring a high-quality sound blanket for noise reduction.

Air Conditioning System Basics
The most common type of system pairs an exterior air conditioner with an interior air handler or furnace, which work in tandem to circulate air throughout your home. Matching your air conditioner with a compatible Armstrong Air® air handler or furnace will generate optimum efficiency and ideal system performance.
How compressor stages affect performance
76º
68º Single stage means cooling is either all the way on or all the way off, creating temperature swings.
74º
70º Two stage runs at low or high operating speeds, depending on conditions, creating more even, consistent temperatures.
72.5º
71.5º Variable capacity gradually ramps up and down to keep the temperature exactly where you want it, using even less power.

How It Works

AIR CONDITIONER

COLD AIR

FURNACE

BLOWER

WARM AIR

1. When it gets warm inside your home, your thermostat automatically activates your air conditioner to compensate.
2. The air conditioner on the outside of your home circulates refrigerant that absorbs heat from the indoor environment through the coil as it travels between the indoor coil and the air conditioner outside.
3. As refrigerant flows through the evaporator coil, a blower in the furnace moves the warm air across the coil surface, removing heat and dispensing the cooled air through your home's ductwork.
4. The captured heat is then sent back to the air conditioner outside to be released into the outside air, cooling your home comfortably and efficiently.

Corrosion Protection
Select Armstrong Air Air Conditioner units feature OmniguardTM Total Corrosion Protection Technology, offering improved corrosion protection compared to traditional coils and preserving the life of your system for years to come.

Exceptional cooling for a home that's just the way you want it.
Inside every Armstrong Air air conditioner, you'll find a high level of technology and craftsmanship, backed by a 10-year Limited Warranty on the compressor* and a 10-year Limited Warranty on parts.*

Model shown 4SCU20LX

MHTTM Technology
Armstrong Air's proprietary heat transfer system uses a specially designed fan shroud, rifled tubing and lanced coil fins for maximum heat transfer and efficiency.
Noise Reduction
A swept-wing fan blade design reduces turbulence, while a heavy-duty compressor blanket further reduces sound levels.
Integrated Compressor Protection
High- and low-pressure switches protect the compressor, helping to ensure lasting performance.
Comfort SyncTM Control Panel
All Pro SeriesTM units continuously monitor internal components for optimum performance and fault prevention, and notify you and your dealer if repairs or maintenance are needed.
Inverter-Driven Scroll Compressor
Rather than running at one or even two speeds, the scroll compressor uses an inverter motor that can change its speed in small, precise increments, saving more energy while holding your temperature precisely where you set it.
Sealed Contactor with Lugs
Completely covers the contactor, protecting it from debris and insects.
