    [description] => 
Having the return air sized properly is very important in getting the correct static pressure. A general rule of thumb is 12"x12" per ton of air conditioning.  In other words, 1 square foot of return per ton of AC unit. 

In addition to the size of the return air, the filter plays a big role in static pressure and the velocity as well. Filters are given a MERS rating. Find out what that means and more in this CTE video.
