A:Answer Hey there, and thanks for reaching out to us about this window air conditioner! Correct sizing is very important when choosing an air conditioner, so we appreciate you asking. This 6,000 BTU unit is ideal for cooling spaces from 150 sq. ft. to 250 sq. ft. While your room is only slightly smaller, when there are more BTUs than the room needs, cooling performance can be negatively impacted. We do have a model, AHP05LZ, which has 5,050 BTUs of cooling power and is meant for rooms from 100 to 150 sq. ft., if that may be a better fit for you. We hope this information is helpful, and are happy to help with any other concerns as well. Best wishes! -Sarah@GEA
