Buying Guide
- : Most units specify compatible window widths. Saddle or U-shaped designs preserve window visibility but require wider openings and adequate sill support.
- : Match BTU to the room’s square footage. Higher BTU models cool more efficiently in larger spaces but may consume more energy if oversized for a small room.
- : Inverter or full-view models tend to be quieter. If a bedroom needs near-silent operation, aim for models advertised under 45 dB.
- : Inverter technology and energy-saver modes can reduce long-term operating costs, especially in rooms with extended cooling needs.
- : Consider 3-in-1 features (Cool, Dry, Fan) for year-round comfort. A programmable timer adds convenience and energy savings.
- : Some units preserve a window view but require precise measurements and, in some cases, non-permanent mounting. Verify your window configuration before purchase.
