Product Information

In fact, we found no compelling new double-hose models from major manufacturers in 2019 or 2020, although a few new ones cropped up in 2021, including our new top pick. In recent years, however, the Department of Energy finalized new standards for measuring the seasonally adjusted cooling capacity (SACC) and combined energy-efficiency ratio (CEER) of portable ACs. In normal cooling modes, portable air conditioners evaporate the collected water and send it outside, but just circulating the humidity over and over is a waste of electricity. Be sure to carefully read the instruction manual before installing your new portable air conditioner.

Our window AC exhaust vents are available in ⅛ inch, 3/16 inch and ¼ inch thicknesses and can be cut to your specifications. We found the built-in user interface to be particularly clear and easy to use; by contrast, the Danby model we tested had the exact same button layout with different markings, and it managed to confuse us every time. This cooling and heating AC is not an inverter model, but it’s just as powerful as our top pick, and it spreads the air more evenly around the room. For example, you could leave the Wave 2 outside your tent and pump fresh conditioned air inside that stuffy space while you’re sleeping.Any time you’re venting into an interior space, you should monitor the temperature in the space you’re venting the heat to, making sure you don’t overheat anything. DeLonghi portable ACs, on the other hand, feature 4-inch exhaust hoses, so they would fit most dryer vents.

It’s a great choice for windowless rooms and semi-enclosed outdoor spaces such as seasonal porches, but it’s an even better option for people who need flexibility or want something to take on the road for camping trips or off-grid living. The Danby DPA100B9IWDB-6 looks surprisingly similar to our runner-up pick, just with a slightly different fan on top.

However, if the external opening of the dryer vent contains a flap, then the unit's hot air exhaust will not be strong enough to push it open. But portable ACs don’t need to vent out a window, so long as you can find another way to send the heat outside. In that regard, it was more consistent than any other AC we tested, with the exception of our also-great pick from Frigidaire.
