  • Product Overview

    With 18,500 BTUs of cooling power and a 10.7 energy efficiency ratio (EER), the Comfort-Aire RADS-183L Window Air Conditioner blends strong cooling power with energy-efficient features. Built to cool up to 1,000 square feet, the Comfort-Aire model offers energy saver and automatic functions and also has the ability to cool, dehumidify, or act in fan-only mode.  

    Various Operating Modes

    The Comfort-Aire RADS-183L is equipped with 5 operating modes that keep your home comfortable all year.

    • Cool: This window AC processes 18,500 BTUs to efficiently cool spaces up to 1,000 square feet.
    • Fan: Use fan-only operation to prevent room stuffiness in cooler temperatures. This window AC is equipped with high, medium, and low speed settings and also features an automatic speed option that chooses a speed based on the ambient temperature.
    • Dry: In Dry mode, this AC serves as a dehumidifier to eliminate humidity as it cools your room. The RADS-183L extracts 91.2 pints of moisture per day and provides immediate comfort while conserving energy.
    • Automatic: When in Auto mode, this model automatically selects cooling or fan-only operation depending on the room’s ambient temperature.
    • Energy Saver: 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, which also lowers your energy consumption.  

    Endless Features

    An easily-accessible washable air filter is simple to clean and reuse, saving you money on replacement filters and ensuring your AC runs efficiently. This unit also includes a Check Filter Indicator that notifies you when the air filter needs to be cleaned. Turn the window AC on or off with specific settings up to 24 hours in advance using the programmable timer. In addition, a full-service digital remote control provides easy access to all features and lets you change modes or fan speeds.

    Window Kit Included

    The Comfort-Aire 18,000 BTU Window Air Conditioner 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 26.5 to 40.5 inches wide or through an outside wall.

    This is a 230-volt AC that uses a NEMA 6-15P plug type. The 3-prong face looks like this:  

    Additional Features

    • 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.​

    • Washable Air Filter: The reusable air filter saves you money and ensures efficiency.​
    • Adjustable Airflow: Two-way adjustable front louver lets you direct the airflow, providing uniform cooling and enhanced comfort.
