Multi Split Air Conditioning Systems Price in Racine – What Is an Air Return Duct?

An air return duct is an integral part of nearly all heating, ventilating and air conditioning (HVAC) systems. Generally, HVAC systems use a forced air process that blows either heat or air conditioning through ductwork into a home or business. An air return duct usually is located either in a hallway or in the ceiling, and its purpose is to extract air from a room and recycle it through the system to further condition it by cooling or heating.

Most central air and heat systems have a condenser that is outdoors and a coil that is located indoors that allows one unit to both heat and cool a building. In the summer, the return duct removes warm air from inside and transports it to the outside through ductwork to be conditioned. 

Multi Split Air Conditioning Systems in Racine – A Sealed HVAC Duct System.

The importance of a sealed HVAC duct system can be attributed to the temperature of the air that is extracted by the return duct. For example, for cooling purposes, warmer air rises to the ceiling and colder air remains closer to the floor.

The air return duct provides circulation of cold air as it pulls the cooler air upward, passing through the warm air that is closer to the ceiling. If there is a leak in the ductwork in any portion of the system, it could pull in unconditioned air, which will take more time and electricity to effectively condition. This usually causes the HVAC system to run longer and use more electricity to achieve the desired temperature.
