Award-Winning Year-Round Comfort with Dual Hose Efficiency

The Whynter ARC-12SDH is a 12,000 BTU portable air conditioner built to cool medium-sized bedrooms, home offices, and apartments up to 400 square feet. The dual-hose system draws in fresh outdoor air to cool your space, then exhausts warm air outside,  delivering faster, more efficient cooling than single-hose models.   With a dedicated heat mode, it keeps you comfortable year-round, cooling in the summer and warming through the colder months, so you never need a separate unit.

Three fan speeds let you match the airflow to your comfort level. At as low as 52 dBA, it runs quietly enough for bedrooms and home offices without disrupting sleep or focus. The built-in dehumidifier pulls excess moisture from the air, so your room stays cool and comfortable even on the most humid summer days. An activated carbon filter tackles odors and airborne impurities, keeping your indoor air fresh. A 24-hour programmable timer means your room is already cool when you walk in, and the sleep mode quietly maintains your set temperature overnight.

No permanent installation needed, just position it near a window, attach the included exhaust hose kit, and start cooling within minutes. Backed by Whynter's 1-year warranty with a 3-year warranty on the compressor, the ARC-12SDH is built to last. If you're looking for a reliable, free-standing portable air conditioning unit that you can move room to room without any permanent modifications, the ARC-12SDH delivers the performance and convenience you need.
