This is because there are far more supply vents in most HVAC systems. In order to be effective at sucking stale air back into the ducts, return air needs bigger vents. Older HVAC systems rely on one return vent in a central part of the home, as this was the norm before central air. Return ducts extract air from the living spaces back to the HVAC unit, feeding either your furnace or air handler. Return vents are usually larger than supply vents and are called grills. A filter is often installed either deep inside a return duct or right at the return grill to protect your HVAC unit from impurities.

In order to minimize friction loss you can: select a duct material with a lower friction coefficient such as metal, use a larger return, avoid sharp or unnecessary bends in the duct ...The size of a return air duct should generally be based on the HVAC system’s capacity. A common rule of thumb is to aim for approximately 400-450 CFM (cubic feet per minute) of airflow per ton of HVAC capacity. For example, a 2-ton system might require a return duct with a size of around 16 inches in diameter. However, specific …These vents suck the air from each room and send it back to the air conditioning or heating system. Return vents tend to be bigger than supply vents, and you won’t feel any air coming from them. When an HVAC system delivers air to a room, it increases that room’s air pressure. Return vents exist to remove the extra air. Now, to properly calculate the return grille size, we have to make these two assumptions: Face velocity is 500 FPM (feet per minute).
