What are Air Ducts?

Think of ductwork as the tunnels of your HVAC system that help move the cool or warm air all throughout your home. Usually, ductwork is constructed from materials such as galvanized steel, aluminum or flexible plastic and are placed behind walls, in ceilings and sometimes even under floors to ensure the proper distribution of air. The purpose of these ducts is to transport the air to every room in your home. This helps the overall temperature regulation and improves air quality. 

Since air ducts are concealed within the home, they can be tricky to clean or to identify any leaks or holes in them. It is a good rule to keep an eye out for a sudden increase in energy bills, weak airflow or excessive noise to determine if there are any leaks or damages within the ductwork.

What are Air Vents?

On the other hand, air vents are the visible openings that connect to the air ducts in your home. This is where the air will blow from, allowing for the correct air flow within the home. These vents also serve as an intake and output points for the airflow, allowing the air to either enter or exit a room. Air vents are usually installed in the walls, floors or ceilings of the home and can vary in size. 

Since the air vents are responsible for letting the air enter your home, it is recommended to keep them clean and clear of dust, debris or any obstructions that can hinder the airflow. It is also recommended to regularly change your air filters to ensure a good indoor air quality and prevent the system from requiring repairs.
