Calculate. Too large or too small HVAC ductwork sizing can cause problems similar to what happens when technicians install an improperly sized HVAC unit. To check for accurate measurements, many techs rely on HVAC duct sizing calculator free tools, such as a ductulator.That would be a 6" duct with a 6"x6" grille or 6"x8" grille and boot for 100-120 cfm to each of 4 registers. Or a 7" duct for 160-180cfm per 6"x8" boot and register. Throw and velocity make a big difference on small right sized systems. The registers Can't Be stamped cheap registers.A rectangular 6×6-inch duct has an airflow of 110 CFM. Bigger 6×12-inch ducts can handle 270 CFM airflow. The bigger the crosssection of ducts, the bigger CFM; that’s pretty obvious. The smallest 6×4 ducts can handle 60 CFM airflow. The biggest 42×12 ducts with 504 sq inch crosssection can handle 3000+ CFM airflow.

However if you want superior air flow I would highly suggest putting in a 20X20 as that gives you far better airflow hands down. There are 12,000 Btu's per ton. The number 24 in the model number indicates the unit is 24,000 Btu's, divided by 12,000 Btu's per ton, equals 2 tons. 24,000 Btu's/12,000 Btu's per ton = 2 tons. Use the following conversion information to determine your existing system size (use the system model number NOT the serial number) 18 = 1.5 tons.That 5 ton unit was obviously designed so the opening can actually push 5 tons of a/c through it.

The static pressure transducer is provided in the single package unit, and 5/16 in. or 1/ ...For supply ducts longer than 10 feet (3 meter), the air is reduced in that run by 10% for every 5 feet over 10 (every 1.5 meter over 3 meters). For example, a 30 foot (9 meter)) run is 60% of an outlet that is 10 foot (3 m) yielding a reduction of 40% (30-10=20, 20÷5=4, 4 ×10=40%). Refer to Bulletin 20-54 for more information.The duct system is a sound trap around the blower. The system will be quiet if the delivered velocities are about 600 feet per minute. 3) The blower mouth (8"x16") is .89 square feet and the design exit air velocity is 1240 cfm/.89 sq. ft. or about 1400 fpm AVERAGE. The associated peak velocity may be over 2000 fpm.
