Even portable air conditioners with dual hoses that vent through the window kit failed to meet customer expectations. While one of the hoses is responsible for bringing air from the outside to cool the condensing unit, the other hose takes hot and moisture-laden air outside. According to tests, dual-hose units were found to be slightly better than single hose units when it comes to regulating room temperatures, but their performance falls short of window units of a similar size.
If you have to buy a portable unit, make sure it’s a dual-hose model. However, studies have shown that even these models have a hard time cooling a room to the desired temperature. Furthermore, rolling an 85 pound AC machine on a carpet is not easy.
The best portable AC units reviews consistently rank the Whynter 14,000 BTU Dual Hose Portable Air Conditioner (ARC-14S) at the top. This is an affordable dual priced unit that can meet your cooling needs. For less than $500, you can get a unit with a built-in heating function.
