How to choose air conditioners

Our picks compare listed BTU capacity, inverter or dual-hose features and controls with price and condition. Higher capacity is not automatically a better fit: match the unit to your room and installation.

Before you buy

Match cooling capacity to the room; check SACC/DOE ratings for portable units.
Confirm voltage, window dimensions and the included hose or installation kit.
Check drainage, noise specifications and returns. Evaporative coolers are not compressor air conditioners.
