negative air pressure is when you take out more air (exhaust hood fans) than you bringing in (make up air).
things i can think of:
1. decrease fan speeds by installing controller
2. increase return air flow by installing more powerful motor
3. open air intake flappers on roof hvac unit (if it has them)
4. keep doors open (as a temporary good weather solution),
Can someone think of more ideas?
