  • Product Overview

    Stay comfortably cool and refreshed all while keeping an eye on your energy consumption and the environment with the Whynter Eco-Friendly 12,000-BTU Portable Air Conditioner. This thermostatically-controlled portable air conditioner cools spaces sized up to 400 square feet efficiently using a cooling system built around the environmentally friendly, ozone-safe R-410A refrigerant. Boasting patented auto-drain technology, a window kit that includes everything you need for exhausting, and intuitive digital controls—the Whynter ARC-12S Portable Air Conditioner is exceptionally easy to setup and use for years of low-hassle spot cooling.

    Effective, Eco-Friendly Cooling

    The Whynter Sno 12,000-BTU Portable Air Conditioner is an effective, efficient, and eco-friendly solution for cooling bedrooms, offices, classrooms, garages, workshops, and computer rooms. The unit can also be used as a supplementary cooling source to help offset the often costly operation of a central air conditioning system. As part of a new generation of green cooling alternatives, the Whynter ARC-12S is constructed with numerous eco-conscious features, including:


    • R-410A Refrigerant – This CFC-free (chlorofluorocarbon-free) refrigerant is a non-ozone-depleting refrigerant that will not harm ozone should a leak occur. As an added plus, portable ACs that use R-410A refrigerant provide more efficient cooling and experience less wear and tear on internal components over their lifespan.
    • RoHS-Compliant – The Whynter 12,000-BTU Portable Air Conditioner complies with the Restriction of Hazardous Substances (RoHS) directive. Often called the lead-free directive, this directive restricts the use of six toxic substances known to harm the environment in the construction of electrical and electronic equipment.
    • High Energy Efficiency – The ARC-12S carries a high Energy Efficiency Ratio (EER) of 11.1. A portable AC's EER is the ratio of cooling capacity (BTUs) to total energy usage (watts). Typically, portable air conditioners with EERs over 10 are considered the most energy efficient and cost-effective cooling options.

    With these eco-friendly features, the Whynter 12,000-BTU Portable AC helps decrease your carbon footprint and maximize your energy savings while cooling.

    Auto-Draining Technology

    For the ultimate in convenience, the Whynter ARC-12S Portable Air Conditioner features Whynter's patented auto-draining condensate technology. This system automatically exhausts all collected condensate outdoors in most environments. The auto-draining system also uses moisture collected during the air intake process in order to cool outgoing air, which boosts the portable AC's efficiency.

    In certain environments, the ambient humidity level may result in some moisture collecting in the ARC-12S' condensate tank. To protect your environment in the event of a condensate overflow, this Whynter portable air conditioner features a tank full indicator that automatically stops AC operation until you can manually empty the tank.

    Multiple Operating Modes, Quiet Operation

    The Whynter Eco-Friendly 12,000-BTU Portable Air Conditioner offers you both convenience and flexibility during operation through three operating modes:

    • Air Conditioner Mode – Cool your space with your choice of three fan speeds – high, medium, and low.
    • Dehumidifier Mode – Use the portable AC as a dehumidifier on especially humid days to remove 91 pints of excess moisture from your environment.
    • Fan Mode – On days when air circulation is enough to stay cool, use the ARC-12S as a comfort-boosting fan.

    The Whynter 12,000-BTU Portable Air Conditioner is also known for its exceptionally quiet operation when compared to similar-size portable ACs. At its highest fan speed, the ARC-12S emits 52.5 decibels of sound, which is slightly louder than a whisper.

    Additional Features

    • Window Kit Included – An upgraded plastic window kit is included for easy installation. The kit includes a window slider panel that is extendable up to 36 inches, an exhaust hose that extends up to 4 feet, and all necessary installation hardware.
    • Thermostatic Control – Use the electronic pushbutton controls to adjust unit cooling from 61 to 89 degrees Fahrenheit.
    • Manual Oscillation Control – Easily adjust airflow from left to right using manually adjusting louvers.
    • 24-Hour Programmable Timer – Program timed operation up to 24 hours using the onboard programmable timer.
    • Washable Pre-Filter – A washable filter helps remove particles and allergens from your room's air. To keep the filter working at its best, clean it after every 100 hours of use.
    • Carbon Filter – The carbon filter helps absorb odors and keep them from returning.
    • Auto Restart – In the event of a power failure, the portable air conditioner will restart automatically.
    • Compressor Time Delay – After switching the portable air conditioner off, the compressor will not turn back on until 3 minutes have passed. This helps protect the quality of the compressor and its operation.
    • LCDI Plug – The Whynter ARC-12S Portable Air Conditioner is equipped with a Leakage-Current Detection and Interruption (LCDI) plug to protect against fire hazards.
    • Carrying Handle – Use the built-in side carrying handles to help you safely move the unit.
    • Remote Control – Control portable AC operation from a comfortable distance with the full-featured remote control.
    • Casters – Easy-roll casters make it easy to move the Whynter portable AC from space to space.

        Comments about Whynter 12,000 BTU Portable Air Conditioner (ARC-12S):

        After having a Portable DeLonghi AC for 17 years I had to replace it and decided to try the Whynter products. I love this product and it is excellent at cooling, but one main doesn't have the ability to select "low noise"...a much needed feature if one uses it for offices and rooms where you need quiet. Otherwise an efficient machine.

        Coldest I've had

        By ValopAlpo

        from USA

        Comments about Whynter 12,000 BTU Portable Air Conditioner (ARC-12S):

        This portable is colder than my 15000 BTU window and my other 12000 btu portable. I wish the louvers could go up and down, more a preference than something that affects performance. It's been doing an incredible job in the bedroom for the past month of oddly warm weather.

        Great Portable!!

        By Frank Norwitch

        from USA

        Verified Buyer

        Comments about Whynter 12,000 BTU Portable Air Conditioner (ARC-12S):

        I bought this as part of my hurricane package of generator and generator panel. My generator will run my entire house with the exception of my 2 big central a/c units. But I figured I could run this portable with the generator and keep our bedroom cool when the juice fails after a 'cane. No hurricane - so far - but my big number one central unit died this past week. Just for grins, I plugged this wee beastie in and, believe it or not, it has managed to keep almost 3000 sq feet of living space at 79 degrees in Florida in August. I am amazed! Without the unit, the house goes to 84 degrees. One of my best purchases!

        No down side to this either. Yeah it has some inherent wind noise factor, but I do not find it very loud or annoying in the least - especially since I am comfortable until the a/c guy gets here with the new parts for the big unit.

        If there were 6 stars, I would give it that.
