Can Furniture Affect Your HVAC Performance?

Can Furniture Affect Your HVAC Performance?HVAC effects can occur from a variety of sources inside a home. Almost any object or material placed in an empty room has some result that may impact air circulation, heat gain or loss, or indoor air quality. Furniture are among the largest objects in a house and therefore can have multiple HVAC effects which, in turn, affect comfort, system components or the health of the indoor environment. Here are some ways furniture and your HVAC system interact.

Airflow

Large furniture diverts paths of airflow into a room which, in turn, may alter “comfort zones.” Placement of furniture can also reduce the amount of heated or cooled air in a room by obstructing airflow from HVAC vents. Merely placing large furniture within 18 inches of a supply vent reduces airflow from the vent enough to potentially alter room temperatures and upset the balance of supply/return air into the room.

Shading

Furniture strategically placed in the path of sunlight streaming through windows casts shadows on the floor and walls of a room. This reduces absorption of solar energy into building materials as well as resultant heat gain. Studies show that rooms with larger areas of shadowed floor and walls are easier to keep cool.

Air Quality

Many furniture materials outgas volatile organic compounds (VOCs) such as formaldehyde, especially when the furniture is new. VOC vapors are known irritants and may cause allergic reactions. Glues used in manufacturer of  furniture as well as foam material in cushions are known sources of VOCs. When new furniture is added to a room, use of a room air filter with active charcoal or carbon filtration can help reduce VOCs.

Component Wear

Indoor air continuously recirculates through the air conditioner evaporator coil. If high levels of volatile organic compound vapors released by furniture are present, the VOCs combine with condensation on the coil to form an acidic substance that may accelerate coil corrosion and cause leakage, refrigerant loss, and impaired cooling performance.
