Hey guys I'm new to this contracting from, and I'm now stuck between a rock and a hard place I'm doing a t.i. and building a restaurant and now on this restaurant there asking me to get an air balance on the a/c units! I have always been told that it was not required under a certain amount of square footage? The reason this leaves me stuck is because my dead line is in a couple of days and I can't get anyone out to balance in time! Please I would appreciate any help I'm doing work in the city of Roseville ca. And the building is under 2500 sq ft! Thank you!!!
