Our Top Pick: Winix Dual-Hose Portable Air Conditioner and Heater with Wi-Fi

The Winix Dual-Hose Portable Air Conditioner and Heater with Wi-Fi earns its place as our top recommendation in the 14,000 BTU portable category. It offers a strong alternative to the BLACK+DECKER Portable Air Conditioner and Heater or the more compact Honeywell Single-Hose Portable Air Conditioner with Dehumidifier, thanks to a rare combination of smart home integration, auto-evaporation, and effective multi-mode operation.

If you are considering a more permanent installation, you might look at high-efficiency window units (such as those in our LG review) like the LG Dual Inverter Window Air Conditioner or the Midea U-Shaped Smart Inverter Window Air Conditioner. For maximum efficiency, a mini-split system—such as the MrCool DIY mini-split, Bosch BMS500-18HDN1, or Pioneer mini-split heat pump—is typically the best long-term investment (see our Carrier mini-split guide or the Daikin RXB12AXVJU buying guide for more on 17 SEER efficiency and permanent installs). However, for versatility and ease of setup, the Winix offers a compelling middle ground.
