Window Size Compatibility

  • Measure your window opening carefully to confirm the air conditioner fits properly, especially for small or unique window sizes.
  • Many units come with adjustable installation kits to accommodate various window widths.

Energy Efficiency

  • Choose units with high CEER or ENERGY STAR certification to reduce energy consumption and save on costs.
  • Features such as reusable filters and energy-saving modes contribute to efficiency.

Installation & Maintenance
