Air Intake Vent Size
I have a 3 ton central AC/Heating unit which uses a 20x24x1 filter. We recently put an addition, approx. 500 sq ft, on the house for a total of approx. 1500 sq ft.
We were told the existing unit was enough to support the addition. Should we make the intake vent a bit larger around 20x25x1 at least?
