Frequently Asked Questions
How many BTUs do I need for a bedroom?
For a typical bedroom, 8,000 BTU (DOE rating) handles 200-300 sq ft, and 10,000-12,000 BTU covers 300-450 sq ft. Note that the DOE rating is more realistic than the ASHRAE rating many brands advertise. For a 150 sq ft bedroom, 8,000 BTU is more than enough.
Are portable air conditioners as good as window units?
Window units are generally more efficient and quieter for the same BTU rating. Portable ACs are less efficient because they vent through a single hose, creating negative pressure. However, portables don't block windows and can be moved between rooms, making them better for renters.
How loud are portable air conditioners?
Most portable ACs run at 50-55 dB on standard mode, comparable to a refrigerator. Sleep or quiet modes reduce this to 44-49 dB. The compressor cycling on and off can be noticeable, so look for models with inverter compressors that run continuously at lower speeds.
