Buying Guide

What size should you choose? Determine room square footage and select a unit with sufficient BTU. Overpowered units waste energy; underpowered units fail to reach comfortable temperatures.

How important are features? Consider modes (cooling, dehumidification, fan), sleep settings, and remote/app control. Smart features improve convenience for busy households.

Where will it be used? For small spaces like bedrooms or dorms, a compact 8,000 BTU unit may suffice. Larger living rooms may need 10,000–14,000 BTU with better airflow.

Drainage and drainage options? Some models use self-evaporation or gravity drainage. Plan for drainage if humidity is high or continuous operation is needed.

Portability and installation? Look for caster wheels, a manageable weight, and easy window venting setups. A straightforward installation reduces the chance of improper venting.

Energy efficiency? Check efficiency ratings (CEER/SEER) and look for features that reduce running time, such as smart thermostats and auto-off when target temperature is reached.

Maintenance considerations? Regularly clean filters and empty water basins if applicable. Self-evaporating designs minimize maintenance needs, but occasional checks help sustain performance.
