Casement Window Air Conditioners

Casement Air Conditioners: The Cooling Solution for Sliding Windows

Casement window air conditioners fit snugly into windows that open horizontally as opposed to vertically. Think of them as a standard window ac units safely turned on their sides. They provide the same cooling capabilities and convenient features but do so in a different shape to bring the relief of AC into more spaces.

Like any room air conditioner, matching the output of a slider/casement air conditioner to the size of your room is important. Overpowered models will leave the room feeling too humid or clammy. Underpowered sliding window units won't be able to effectively cool your space. An 8,000 BTU window unit is the perfect size for rooms with 300 to 350 square feet. Check out our Air Conditioner Sizing and Buying Guide for a complete sizing chart.

Significant advances in energy efficiency have dramatically lowered the operating costs of portable air conditioners, including casement window AC units. Look for ENERGY STAR certified models to keep energy costs to a minimum. Shopping for models with a 24-hour timer is another great way to save power. These timers let you delay the start of the AC with simple electronic controls so that you can come home to a cool house without wasting energy running the air conditioner while you're out.

Sleep mode is another great feature to help keep utility bills low. This mode allows temperatures to slowly rise throughout the night when our bodies don't require as much cooling. Casement air conditioners with multiple fan speeds also help lower your energy bill. Sometimes a bit of airflow is all your space needs. And with variable speed fans, you can fine-tune that airflow.
