In homes that are 1,600 square feet or less, the North Carolina Mechanical Code permits the use of a central return system. This is important for ensuring proper air circulation and balance within the HVAC system. A central return effectively pulls air from various rooms back into the HVAC system for reconditioning, which can enhance the efficiency of heating and cooling throughout the residence.

Therefore, as long as the system is designed appropriately to maintain air quality and fulfill the airflow requirements necessary for adequate heating and cooling, a central return is fully allowable in such sized dwellings. This establishes an efficient pathway for air movement without the need for additional specifications or complications that might arise in larger or more complex scenarios.
