We live in the south - and the gym is having a hard time keeping it comfortable this summer. We have had an unusual year for record temps for so many days in a row, which doesn't help. With the a/c running the warehouse still won't cool below 85. very little wind/breeze so opening the bay doors doesn't really help. thought about the huge fans but they are thousands of dollars. do other gyms have this problem? how have you solved it?
