HVAC - Registers

Registers control air flow from your heating and cooling system within each room of your home.

Care and Maintenance Tips Do Not Restrict Airflow

  • Arrange furniture and draperies to allow unobstructed airflow from registers and to cold air returns. If cold air is unable to return to the furnace, the flow of heated air to that area of your home becomes restricted.
  • There should be a minimum 1/4" gap on the bottom of doors so that the air can flow from a room with a closed door back to the room or hallway to the return air vent.

When Operating Air Conditioning

  • Closing dampers in unused rooms during warmer months when running the air conditioner can improve system efficiency by limiting the rooms in the home that need cool air sent to them.

When Operating Furnace

  • When running the heat during colder months, adjusting the dampers can help distribute warm air more evenly through the home. However, adjust dampers one at a time to monitor the effects in the other rooms.
  • Closing too many registers at once can overheat the furnace by reducing airflow, blowing holes in your ducts. Refer to your manufacturer's guide or contact your HVAC contractor to discuss how many (if any) registers you can safely close according to the size and type of your heating system.
