A central heating, ventilation, and air conditioning system sends conditioned air through ducts to rooms and pulls stale air back to the air handler. The ductwork of your Chambersburg, PA HVAC system includes both supply and return vents for air circulation. When the same amount of air enters and leaves a room, the system is balanced. Blocked or dirty vents affect the system’s pressure, which can result in uneven heating and cooling and loss of comfort.
Supply vents deliver conditioned air to rooms. When a system is installed, the HVAC contractor determines the size and number of supply registers required per room based on load. A room may have more than one supply vent. Vents usually have adjustable slats or louvers that let you direct the airflow or close the vent completely. Closing or blocking vents affect the pressure in the entire building, which affects how much air reaches each space.
Return vents route the air inside a room back to the HVAC duct system. Return vents are larger than supply vents and do not have louvers. However, they usually have filters that capture airborne pollutants and keep them from being sucked into the HVAC system.
Older homes may have only one return vent situated in a central location, such as a hallway. To compensate, doors often have a gap at the bottom to serve as a return air pathway. Newer homes often have return vents in each room. Two-story homes should have at least one return vent on each floor.
Check Supply and Return Vents
Keep curtains, furniture, carpets and other items away from both supply and return vents to allow air to circulate freely. When vents are blocked, air pressure is affected. Cleaning the grilles covering vents regularly also helps air to flow freely.
