I’m often asked for checklists that can help employees and barn owners keep up on the little things that make a ventilation system successful in meeting the moisture and heat removal goals that the system was designed for. I ran across the following in my files today as an example of what a monthly list might contain. I’m sure each of you can add to this list to personalize it to your facilities.
