Whynter Air Conditioner and Portable Heater with Dehumidifier and Fan for Rooms Up to 400 Sq Ft, Includes Activated Carbon Filter and Storage Bag, Silver

Product Information

While the specifics will change unit to unit, this is generally how air conditioners remove heat from the air.

Super-powered cooling—the Whynter ARC-14S might not be as compact as some, but it’s still one of the best portable AC units we’ve ever tested.However, that cooling isn’t particularly even. While we measured it dropping a nearby sensor about 20°F in only five minutes, that super-fast cooling doesn’t extend to the whole room, which had temperature discrepancies of up to 10°F. While it’s a little bigger than other portable AC units at 35.5 inches tall, this machine is more than capable, and is just right for daily use in a game room, garage or man cave. Our take: The dual-hose design and 12,000 BTU rating makethe ARC-122DS an ideal portable AC unit for cooling rooms up to 400-square feet. It's effective even when the temperatures exceed 95°F.

In our post that covers what air conditioner size you need, we compared capacities of different air conditioners in “British Thermal Units” (BTUs, a measurement of an absolute amount of heat) per hour. But the way BTUs are removed from your home in real-world conditions is often different from the way a testing system in a laboratory works. Compactly designed, at only 27 inches high, the value-priced FHPC082AC1 is a single hose Frigidaire portable air conditioner that’s sized well for RVs, trailers or smaller workspaces. It also comes with caster wheels, improving its portability.While it's small in size, it doesn't have any handles to grip onto, making portability more difficult than most. The unit features edges towards its bottom to grab onto, but these can only accommodate fingertips. Dave Ellerby, the Chief Scientist at Reviewed, tested our most recent batch of window air conditioners. In the New England climate, summers can get especially hot, so he has a lot of experience using them, and built an all-new testing chamber for air conditioners to make sure our results would be even more consistent. The Tests What we like: The 10,000 BTU system runs at two fan speeds, including a SilverShield Filter and the Whynter patented auto drain function. This automatically removes all condensation in most environments. The optional “heat-pump” heating modes in the ARC-122DHP or ARC-14SH is also a big plus for those comparison shopping. It’s not as effective as a space heater in really cold climates, but if you just need a bit of warmth on a chilly morning it’s an effective two-in-one system. How many BTUs do you need? A cooling test was our performance indicator. We outfitted our testing chamber (200 square feet) with temperature sensors placed at the center of each of its four walls, with a fifth sensor in the middle of the room. We set up a control sensor outside the room.
