Energy Efficiency
Select window AC units with a high CEER (Combined Energy Efficiency Ratio) to keep electricity costs low without compromising cooling power. Energy Star-rated units or CEER values above 10.0 are recommended for efficient year-round use.
Control Features and Smart Connectivity
Modern units offer mechanical dials for simple adjustments or electronic controls with thermostat precision. For added convenience, consider smart features like WiFi connectivity and voice assistant compatibility for remote operation and scheduled cooling.

Many 5000 BTU units also include fan-only modes, dehumidifiers, multiple fan speeds, and directional airflow control. These features enhance comfort versatility and adapt the AC performance according to seasonal or environmental needs.
