Choosing the right BTU is crucial for effective cooling. Here's a general guideline, but remember to consider other factors like sunlight and ceiling height:

100-150 square feet: 5,000 - 6,000 BTU
150-250 square feet: 6,000 - 8,000 BTU
250-300 square feet: 8,000 - 10,000 BTU
300-350 square feet: 10,000 - 12,000 BTU
350-400 square feet: 12,000 - 14,000 BTU
400-450 square feet: 14,000 - 15,000 BTU
450-550 square feet: 15,000 - 18,000 BTU
550-700 square feet: 18,000 - 24,000 BTU

Consider these factors when adjusting the BTU recommendation:

Sunlight: If the room is very sunny, increase the BTU by about 10%.
Shade: If the room is heavily shaded, decrease the BTU by about 10%.
Kitchen: If the room is a kitchen, increase the BTU by about 4,000 BTU.
Occupancy: If more than two people regularly occupy the room, add 600 BTU for each additional person.
Ceiling Height: If the ceiling is higher than 8 feet, you may need to increase the BTU.

Q4: What are the latest energy efficiency standards for window air conditioners in 2025, and how will they affect my purchase?
