Window Air Conditioners: A Comprehensive Guide
Choosing the Right Size Air Conditioner
Choosing the right size air conditioner is crucial for efficient cooling and optimal comfort. To determine the appropriate BTU rating for your room, follow these steps:
- Measure the square footage of the room: Multiply the length and width of the room to get the square footage.
- Use a BTU calculator: Refer to the sizing chart below or use an online BTU calculator to find the recommended BTU rating for your room size.

Window Opening Size Requirements
Before purchasing a window air conditioner, measure the window opening to ensure the unit will fit properly. Measure from the bottom of the window to the top of the window ledge and from the inner-most part of the side window opening. Check the sizing chart on the box of the air conditioner to confirm it meets the opening requirements.
