Armstrong Air 4SCU16LE Air Conditioner

Quiet, Single-Stage Air Conditioner
Up to 16 SEER Efficiency Rating*
SEER (Seasonal Energy Efficiency Ratio) rates the energy efficiency of your cooling equipment. The higher the SEER rating, the more efficiently your unit operates, saving you money on utility bills.
Up to 15.2 SEER2 Efficiency Rating*
SEER2 stands for Seasonal Energy Efficiency Ratio and is a measurement of the efficiency of cooling products. The “2” refers to the 2023 updated testing standards. Compared to original SEER ratings, these new standards are updated to more accurately reflect performance in real-world installations. Think of it like the difference between highway vs. city miles per gallon: SEER represents performance in perfect conditions, while SEER2 presents a more realistic picture of performance – i.e., stop-and-go traffic.
ENERGY STAR® Certified
The ENERGY STAR program is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy helping us all save money and protect the environment through energy-efficient products and practices.
Single-Stage Compressor
Our reliable single-stage compressors are made from quality materials and run-tested well beyond industry standards to ensure your unit provides you with year-after-year comfort.
Heavy-Duty Compressor Blanket
Greatly reduces operating sound so your outdoor entertaining is not interrupted.
Omniguard® Total Corrosion Protection Technology
Our outdoor units feature Omniguard Total Corrosion Protection Technology, offering improved corrosion protection compared to traditional coils and preserving the life of your system for years to come.
Integrated Compressor Protection
The combination of both high- and low-pressure switches give additional reliability to each of our cooling units. The high-pressure switch prevents operation if refrigerant pressures exceed safe levels, protecting the compressor. If your unit does not have enough refrigerant, the low-pressure switch prevents the unit from drawing in moisture and other contaminants while operating.
MHT™ Technology
MHT™ Technology helps transfer heat in and out of your home more efficiently. Featuring lanced coil fins for greater coil-to-air contact, rifled tubing for enhanced refrigerant flow, and a fan venturi cover to focus air flow over the coils to more efficiently remove heat in cooling mode and absorb heat from the air in heating mode. That means our air conditioners and heat pumps are designed to last longer and help ensure your home stays consistently comfortable.
