DO NOT PUT THEM IN CLOSETS AND OR SMALL LAUNDRY ROOMS UNLESS YOU CAN VENT 700 square feet of unconditioned air space to them . They are noisy , but a garage in a humid hot southern climate is a good choice and with a time clock set for 11:00 AM to 4: 00 PM when the air in the garage is hot AND solar grid tied system is operating is a great strategy .
