Hello. My name is ***** ***** I'll do my best to help. Let's get started and see what we can do.What is the complete model on outdoor unit?The btus of the system will determine how many cfms of air we need to move.For example a 3 ton system will move 1200 cfms.To size properly we use what is called a ductulator. You can purchase online for about 20 bucks. See link:
