Roof-mounted attic fan at the car wash? The smaller unit is for 1650 sq. ft. and 1170 cfm for $53.82 and the larger is 2100 sq. ft. and 1500 cfm is $110.
Today, it was 98 outside according to my weep mizer and a thermometer about two or three feet from the roof says it was about 95 inside.
There is already a hole in the roof for the boiler and the fan needs a 14 1/2" hole cut. Would this really help with the heat?
