  • Product Overview

    The Comfort-Aire REG-81L Window Air Conditioner with Electric Heat provides room comfort all year because it cools, heats, and dehumidifies. This window AC offers 8,000 BTUs of cooling power and is ideal for spaces up to 300 square feet. Its easy-to-use features include Energy Saver and Sleep modes, a full-function remote control, and washable air filter.

    Versatile Operation

    The Comfort-Aire REG-81L is equipped with several individual operating modes that ensure comfortable room temperatures all year.

    • Cool: Using 8,000 BTUs of cooling power, this Comfort-Aire air conditioner efficiently replaces hot air with a refreshing cool breeze.
    • Heat: This model is designed for supplemental heating and offers 3,500 BTUs of heating power.
    • Dry: To adequately cool your space, this air conditioner must remove moisture from the air. In Dry mode, this window AC eliminates humidity as it cools your room by extracting 35.5 pints of moisture per day.
    • Fan: Use fan-only operation to prevent room stuffiness in cooler temperatures. This model is equipped with high, medium, and low speed settings and also features an auto fan speed that automatically selects a speed based on the ambient room temperature.

    Money-Saving Features

    This window AC offers additional features and modes that reduce cost and energy consumption. An Energy Saver mode maintains a reasonable room temperature while you’re at work or out of town because it automatically stops the fan and compressor when your optimal temperature is reached.  In sleep mode, the temperature slightly increases and then maintains a comfortable room temperature while you sleep. An Auto mode automatically selects cooling or fan-only operation depending on ambient room temperature. This ensures the unit only runs in Cooling mode when it’s needed.

    The reusable air filter can be removed and washed, saving you money on replacement filters. A Check Filter Indicator notifies you when it’s time to clean the filter and ensures the unit maintains maximum efficiency.

    Window Kit Included

    The Comfort-Aire 8,000 BTU Window Air Conditioner with Electric Heat is equipped with all the tools you need for secure window installation. Its installation kit includes a top-mounting rail, vertical sash seal, accordion panels, and support brackets. It can be mounted in windows between 26.875 to 36 inches wide or through an outside wall.

    This is a 115-volt AC that uses a NEMA 5-15P plug type. The 3-prong face looks like this:  


    Additional Features

    • Digital Remote Control: Conveniently change modes, fan speeds, and other settings with this full-function remote control.
    • Eco-Friendly: Its R-410A refrigerant does not contribute to ozone depletion.
    • Auto Restart: In the event of a power failure, it will automatically restart and resume operation in the last programmed settings once power is restored.
    • Digital Display: The digital display screen shows the current room temperature and the remaining operation time when the timer is set.
    • 24-Hour Timer: Using this feature, you can program the window AC to start up or power down in 30-minute intervals for up to 24 hours.
    • Adjustable Airflow: Two-way adjustable front louver lets you direct the airflow, providing uniform cooling and enhanced comfort.
    • Washable Air Filter: The reusable air filter saves you money and ensures efficiency.
