Balance air pressure with transfer grilles

Balanced air distribution means a more comfortable house.
HVAC(Heating, ventilation, and air conditioning). Collectively, the mechanical systems that heat, ventilate, and cool a building. systems that use heating and cooling ducts are susceptible to pressure imbalances that can lower indoor comfort. Transfer grilles are a simple way of equalizing pressure from room to room. When noise transmission is a potential problem, consider grilles with baffles to muffle sound. Dedicated return ducts in each room or jumper ducts are other options.

For more information on transfer grilles, see "Return-Air Problems."
