  • Product Overview

    Part of Friedrich’s dynamic Kühl line of window air conditioners, the Friedrich SM18N30A 20,000 BTU Window Air Conditioner was designed to meet your cooling needs and exceed your expectations of what a window AC can do. The Kühl SM18N30A is packed with convenient features, such as ComfortWatch Technology, a multifunctional LCD display, and EntryGard protection. You can even customize the look of your Friedrich air conditioner with the optional Kühl Decorative Color Front Kit.

    The SM18N30A not only features 20,000 BTUs of cooling power for large rooms up to 1100 square feet, but its Energy Star-rating proves it’s also efficient. Backed by trusted Friedrich construction, this window AC features a convenient slide-out chassis, 8-way air flow control, and vibration-absorbing technology.

    NOTE: This Friedrich Window Air Conditioner uses a NEMA 6-15P plug type.
    This is a 250-volt/15-amp, 3-prong plug with a face that looks like this:

    Energy Efficient Design

    With an energy efficiency ratio (EER) of 9.8, the Friedrich SM18N30A helps you reduce energy costs without sacrificing functionality. In addition, this window AC uses eco-friendly R-410A refrigerant and comes in recyclable packaging. For improved energy efficiency, Friedrich SM18N30A features an Auto Fan mode that selects which of the 4 speeds is needed most based on ambient temperature.

    This window AC comes with a washable antimicrobial air filter, which prevents the growth and distribution of harmful bacteria and fungus into your indoor environment.

    User-Friendly Climate Control

    Don’t waste time constantly adjusting dials or making countless trips to your window AC to try to achieve a comfortable temperature. With multiple programmable settings, intuitive features, and an included remote control, the Friedrich Kühl SM18N30A makes total cooling comfort a breeze.

    The Friedrich Kuhl SM18N30A includes two 7-day energy management programs which can be accessed and selected from the unit's controls. The SM18N30A is Wi-Fi ready, and the optional Wi-Fi adaptor allows you to adjust your Kuhl air conditioner from your smartphone or your computer.

    Rugged Friedrich Construction and Cooling Power

    This Friedrich window air conditioner comes with all of the necessary hardware and instructions for conveniently installing the air conditioner. Once installed, this Friedrich window AC includes EntryGard anti-intrusion protection, an insect barrier, and a protective rear grille to give you peace of mind and allow you to relax and enjoy the AC’s exceptional cooling power.

    The Kühl SM18N30A is constructed of heavy-gauge galvanized steel, rifled copper tubing, and high-tech aluminum fins to guarantee years of reliable cooling. Rugged side panels further reduce noise and prevent unwanted light from entering your room.

    Additional Features

    • 7-Day Programmable Thermostat: This advanced programmable thermostat can be used to automatically turn the air conditioner on or off and even change modes to maintain temperatures throughout the day.
    • ComfortWatch Technology: This feature samples the air to ensure that the air conditioner consistently maintains your ideal room temperature.
    • Push-Button Controls: Easily toggle between Cool and Fan-only modes, as well as adjust the fan speed, schedule settings, program the time, and much more with these easy-to-use controls.
    • Maintenance Required: When maintenance is necessary, a service icon will appear in the LCD display.
    • Panel Lock: The control panel buttons can be locked to prevent inadvertent operation.
    • Auto Restart and Memory Backup: In the event that your window air conditioner loses power unexpectedly, your ideal settings are automatically saved and will continue operating as soon as power is restored.
    • Moisture Removal: This unit removes 6.0 pints of excess moisture per hour while cooling.
    • Check Filter Indicator: This convenient indicator alerts you when the filter needs to be changed.
    • External Thermostat Control: These window air conditioners also provide the option of adding an external thermostat for remote temperature sensing and control. (Friedrich recommends using an RT4 or RT5 digital thermostat.)
    • Optional Audible Alerts: Choose whether or not your controls emit a “beep” sound when pressed.
    • 4 Vent Locations: Engineers designed this Friedrich Kühl model to draw air inside through four different vent locations, as opposed to a single point.


    This Energy Star-rated model is both powerful enough to cool large rooms and durable to last several years of continuous use.

    What Customers Love

    • Energy-Efficient: A fan-only option, two 7-day energy management programs, and an EER of 9.8 help conserve energy and reduce costs.
    • Durable Construction: Built to withstand several years of continuous use, its steel exterior and heavy-duty side curtains protect internal components from environmental factors. 

    Things To Consider

    • 20,000 BTUs: Think about the size of your space when considering this AC. This model was built to cool and dehumidify medium- to large-sized spaces. It may cool small rooms too quickly and shut off before properly dehumidifying the area.
