Top Features of the 4SCU18LS

  • Pro Series™ Systems

    Pair this model with a Pro Series™ variable speed furnace and a Comfort Sync thermostat, for optimum performance. With the Pro Series, you’re in control of every aspect of your home’s climate, as well as your energy costs. Explore the Armstrong Air Pro Series™.

  • Two-Stage Scroll Compressor

    The two-stage scroll compressor will run longer, gentler cooling cycles at low capacity during mild weather and switch to full capacity on hotter days, keeping you comfortable all season long.

  • Comfort Sync Thermostat

    When you pair this model with the Comfort Sync thermostat, the system will continuously monitor internal components for optimum performance. Comfort Sync puts you in total control of your home environment with remote temperature adjustment from anywhere in the world, even your couch, via smartphone app. When Comfort Sync detects that repairs and regular maintenance are needed, it alerts you or your dealer instantly, so your perfect environment never ends.

  • Up to 18 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.

  • Integrated Compressor Protection

    Integrated Compressor Protection: The combination of both high and low pressure switches give additional reliability to each Armstrong Air cooling unit. The high pressure switch prevents operation in the event that refrigerant pressures exceed safe levels, protecting the compressor. In the event that 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

    Armstrong Air’s proprietary heat transfer system. A specially designed fan shroud pulls air evenly throughout the air conditioner’s coil surface. The coil features rifled tubing to enhance refrigerant flow, while lanced coil fins increase surface contact between metal and air. All combine for maximum heat transfer and efficiency.
