What size supply duct for 3 ton unit.

With only 423 sq in of return your air velocity through the grille would be just over 400 ft/min, a good number as far as noise is concerned. Air velocity of more than 500 ft/min will be too noisy for a residential system. As important as air velocity is for noise, also consider the pressure drop across the grille and filter.

Be notified when an answer is posted.If you have paired this furnace with a 3 ton A/C unit then that is a big mistake. 2.5 ton would be the correct size. Anyways, your furnace maxes out at 1,025 CFM so you need one of the following: 16" flex duct (this is rated for 1,000 cfm so it should be fine) 16" rigid duct (this is rated for 1,200 cfm but 15" doesn't exist)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.

The size of the HVAC unit you'll need for the whole house can be found using the unit's average output and the square footage of your home. As a rule of thumb, you'll need 400 CFM of airflow per ton of air conditioning; it takes about 1 CFM of air to heat or cool 1 to 1.25 square feet of floor area. Last, you'll need to understand duct friction.

For the 3-ton, the CFM is 1200, given that 1 ton is equal to 400 CFMs. If this is the system you have, you should use a return and supply vent that matches the size of the AC in terms of the CFM it supports. If you use a small air filter than the system requires, you may also have a problem due to system cracks.

For instance, 400 cfm ÷ 350 x 144 = 164.57 sq.in. So, the possible grille sizes are 20×8 (160 sq.in), 16×10 (160 sq.in) or 14×12 (168 sq.in) depending on your duct size. The above way is based on the grille sizing formula which:The return duct size of 16 inches is insufficient for a 3-ton AC. A 3-ton AC should have a return duct 18 inches in diameter. For a 3-ton AC, a 16-inch return duct is too small. Ducts that are too small will increase static pressure, which will cause too much noise when air passes through the AC. The heating unit will be overworked because ...To know the size of the return air duct for your four-ton unit, use this formula: For a rectangular duct, multiply the size of the AC by 144 square inches, 4×144=576. The square root of 576 is 24, so the size of a rectangular return duct. For a round duct, you will need the CFM rating, which is 400 per ton. Multiply 4×400.

HVAC system prices can have a $2,800.00 difference in cost depending on the tonnage you need.
