Do air returns need ducts?

If you live in a home that has rooms that are either too hot in hot weather or are cold in cold weather you could have a return-air duct issue. Return air ducts are necessary for just about every room.

What is the purpose of the supply ducts?

The supply ductwork carries the heated or cooled air from your HVAC equipment to your indoor spaces. The return air ducts also provide important functions for proper HVAC system operation.

Can you use flex duct return air?

Yes! You can use flex ducts for your return ducts. However, you have to make sure it fulfills all the necessary criteria. These include pressure checks, proper wrapping, and marking, airflow control, etc.

What is the function of a supply and return duct in HVAC?

So, in a nutshell, it recycles air from each room in your home. Warm air travels through a specific set of ducts (called a supply duct), and once cooled down, it travels back to the vents through another set of ducts (called a return duct).

What is the difference between supply and return vents?

The supply vents in your home blow conditioned air out into your rooms. This air travels from your heating and cooling system, through your ductwork and out of the supply vents. The return vents in your home suck the air from your rooms into your return ducts and back to your heating and cooling system.

What is the purpose of cold air return vents?

The return registers draw stale air into the ductwork, where it’s pulled through the filter to capture dust and debris and then delivered back to the HVAC equipment for reconditioning. However, the most important function of the cold air return registers is ensuring ample airflow through the HVAC system.

What is return air duct?

Return air ducts balance airflow in your HVAC system — The primary role of return ducts is to bring air that has been warmed or cooled back to your furnace or air conditioner. This air is returned so that it can be heated or cooled again, filtered of particulates and contaminants, and redistributed inside your home.

What do return vents do?

Your Return Vents Are Responsible for Air Pressure When your HVAC system blows air into your home, that changes the air pressure inside. The excess air needs somewhere to go, and that spot is the return vent.

Where do you put return air vents?

The best location of the return vents depends on whether the system is heating or cooling the air. If it’s cooling, the return vents should be near the ceiling, where the warm air collects, but if it’s heating, the return vents should draw cool air from the floors.

Why ducts are used in air conditioning system?

Ducts are conduits or passages used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air. The needed airflows include, for example, supply air, return air, and exhaust air. As such, air ducts are one method of ensuring acceptable indoor air quality as well as thermal comfort.
