  • Product Overview

    Cool your space the environmentally friendly way with the Whynter 12,000-BTU Dual-Hose Portable Air Conditioner. This eco-friendly portable AC—available in a cooling-only and a cooling plus heat model—effectively cools areas sized up to 400 square feet and boasts numerous features for convenient operation. With a cooling system built around the new ozone-safe R-410A refrigerant, the Whynter ARC-12SD Portable Air Conditioner and Whynter ARC-12SDH Portable Air Conditioner and Heater help reduce your impact on the environment while keeping you comfortably cool and refreshed. Other top features include intuitive electronic controls, patented auto-draining technology, and a window kit that provides everything you need for installation in a snap.

    Both the ARC-12SH and ARC-12SDH are effective, efficient, and eco-friendly solutions for cooling bedrooms, offices, classrooms, garages, workshops, and computer rooms. These units can also be used as supplementary cooling sources to help offset the often costly operation of a central air conditioning system.

    Dual-Hose Cooling, Auto-Draining Technology

    These Whynter portable air conditioners are equipped with double exhaust hoses, which help increase cooling efficiency within your room. During operation, one exhaust hose draws air in from the outside and uses the air to cool the portable ACs' internal components. The second exhaust hose then expels warm air outside, ensuring that only cool air is returned to your space. Because there is less of a chance that warm air exhaust will counteract the cooling process, dual-hose portable air conditioners may be slightly more efficient than their single-hose counterparts.

    For the ultimate in convenience, the Whynter ARC-12SD and ARC12SDH Portable Air Conditioners also feature Whynter's patented auto-draining condensate technology. This system automatically exhausts all collected condensate outdoors in most environments. In certain environments, the ambient humidity level may result in some moisture collecting in the unit's condensate tank. To protect your environment in the event of a condensate overflow, these Whynter portable air conditioner systems feature tank full indicators that automatically stop AC operation until you can manually empty the tank.

    Convenient and Flexible Operation

    The Whynter Eco-Friendly 12,000-BTU Dual-Hose Portable Air Conditioner offers you both convenience and flexibility during operation through multiple 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 96 pints of excess moisture from your environment.
    • Fan Mode – On days when air circulation is enough to stay cool, use the ARC-12SD/H as a comfort-boosting fan.
    • Heater Mode – A feature on the Whynter ARC-12SDH model only, the heater mode gently warms your space during the colder months using 11,000 BTUs.

    The Whynter 12,000-BTU Dual-Hose Portable Air Conditioner is also known for its exceptionally quiet operation when compared to similar-size portable ACs. At their highest fan speeds, the ARC-12SD and ARC-12SDH emit 56 decibels of sound, which is equivalent to the sound of normal conversation.

    Environmentally Conscious Operation

    As part of a new generation of green cooling alternatives, the Whynter ARC-12SD and ARC-12SDH are constructed with numerous eco-conscious features, including:


    • RoHS-Compliant – These Whynter portable air conditioners comply 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 –Both portable ACs carry a high Energy Efficiency Ratio (EER) of 10.9. 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.
    • 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.

    With these eco-friendly features, both the Whynter ARC-12SD Portable AC and the Whynter ARC-12SDH Portable Air Conditioner and Heater help decrease your carbon footprint and maximize your energy savings while cooling.

    Other Highlighted Features

    • Thermostatic Control – Use the electronic pushbutton controls to adjust unit cooling from 61 to 89 degrees Fahrenheit.
    • 24-Hour Programmable Timer – Program timed operation up to 24 hours using the onboard programmable timer.
    • Manual Oscillation Control – Easily adjust airflow from left to right using manually adjusting louvers.
    • 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.
    • LCDI Plug – These portable ACs are equipped with Leakage-Current Detection and Interruption (LCDI) plugs to protect against fire hazards.
    • Auto Restart – In the event of a power failure, this eco-friendly 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.
    • 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, two exhaust hoses that extend up to 4 feet, and all necessary installation hardware.
    • 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 Dual Hose Portable Air Conditioner:

    I looked for a long time before buying this unit. When the box arrived, I was shocked at the size and weight - almost 100 lbs!!!! But once unpacked, the unit was much smaller and easier to move around. I have a 350 square foot finished attic space that I placed this unit in. After a quick installation, I turned it on and was a little surprised by how load it was, but I have no experience with these kind of units, so I assume that its a normal sound level. The room was almost 90 degrees, and it took almost 3 hours to get the room down to 75 degrees. Doesn't seem great but in an attic space, in the middle of the day, in Southern California's summer heat - I didn't think it was too bad. Not to mention that there is a huge opening in the floor where the stairs enter the attic, and all the hot air from the 3000 square foot house funnels right up into the attic. So, I honestly think that given the extreme condition of my application, this machine does a decent job. As far as design goes, it looks like a little nondescript robot - clean lines - nice color. I don't like the temperature display at all - ridiculously bright neon blue. I guess it's great if you need to read it from 50 feet away, but just ugly.

    All in all, this AC unit is great value and solid performer. I would recommend this to anyone. Sylvane also has the best prices I could find anywhere online.

    Comments about Whynter 12,000 BTU Dual Hose Portable Air Conditioner:

    This unit is a high output room air conditioner. It is rather bulky, and not too attractive because of the hoses. However, it's very efficient and works well for temporary purposes. It's quiet and easy to use.

    Comments about Whynter 12,000 BTU Dual Hose Portable Air Conditioner:

    Easy to set up. We also had a piece of plexiglass cut with holes to fit into a sliding glass door. We first tried the unit when outside temps were near 100 degrees and high humidity, in a large open space (20 x 25, with some enclosed spaces). It definitely cooled the room and reduced the humidity but had a hard time bringing the temp to the 76 degrees it was set to.

    Keeping cool with less effort

    By Frank Knight

    from USA

    Verified Buyer

    Comments about Whynter 12,000 BTU Dual Hose Portable Air Conditioner:

    We switched from window A/C units to portable single hose units several years ago. Last year the upstairs single hose unit failed and we switched to a dual hose Whynter ARC-14S unit and were very please with how effective it was and also relatively quieter.

    This year the old single hose unit downstairs failed and I took the opportunity to upgrade to a Whynter ARC-12SD. Again the difference was very noticeable and we are extremely pleased with the performance from a relatively quieter unit. During the cooler months they easily roll into the corner of a closet so are a lot easier on the back than window units. If you live in area where A/C is only needed a few months of the year do yourself a favor and buy one of the dual hose Whynter units. I am certain you will be please with their performance and ease of installation.
