Our research and testing highlight top performers that deliver the perfect mix of cooling power, energy efficiency, and value.
How to Choose the Right Window AC Size
Choosing the right size window air conditioner is maybe the most significant decision you’ll make during your purchase. A bigger AC unit isn’t always better and could create uncomfortable conditions in your home.
Match BTUs to room size: These general guidelines will help you achieve optimal cooling:
150-250 sq. ft. rooms: 5,000-6,500 BTUs
250-350 sq. ft. rooms: 7,000-8,500 BTUs
350-550 sq. ft. rooms: 9,800-12,500 BTUs
A simple calculation method: multiply your room’s square footage by 20 to estimate needed BTUs. A 320 sq. ft. room would need approximately 6,400 BTUs.
Make necessary adjustments: Your BTU calculation should account for these factors:
Heavily shaded rooms need 10% less capacity
Sunny rooms require 10% more capacity
Each person beyond two occupants adds 600 BTUs
Kitchen installations need an extra 4,000 BTUs
An improperly sized AC unit creates issues beyond comfort. Oversized units cycle frequently, which creates uneven temperatures and increases component wear. This constant cycling results in higher utility bills despite promises of better cooling.
The time spent sizing your window air conditioner correctly pays off with consistent comfort, better humidity control, and improved energy efficiency during summer months.
