Compare Portable Air Conditioners

Most portable ACs include a window kit. You'll need to: 1) Assemble the window kit to fit your window size, 2) Connect the exhaust hose(s) to the unit and the window kit, 3) Extend the adjustable panel to fill the window gap, 4) Close the window on the kit. Sliding windows are easiest; casement windows may need an alternative kit. The hose should be as short and straight as possible—long or kinked hoses reduce efficiency. No drilling or permanent modifications required.

Not effectively. Portable ACs are designed for single-room use. Moving one between rooms works if you're okay with only cooling the room you're in. Cooling an entire apartment would require multiple units or a central system. Size the unit for the largest room you'll use it in. For open-plan spaces, a higher BTU unit can handle the combined area—but closed doors will block airflow.

Some do. The Midea Duo Smart Inverter includes heating for year-round use—it functions as a heat pump in winter. Most portable ACs are cooling-only. If you want one unit for both seasons, the Midea Duo is the best option. Otherwise, you'll need a separate space heater for winter.
