As an expert in the field of heating, ventilation, and air conditioning (HVAC), I have seen firsthand the impact that proper duct placement can have on a home's energy efficiency and overall comfort. The location of ducts plays a crucial role in the effectiveness of an HVAC system, yet many homeowners may not realize its importance. In this article, I will discuss the different places where ducts can be located in a house and why it is crucial to pay attention to their placement. First and foremost, it is important to understand that ducts can be located inside floors, ceilings, or walls. This means that if you have ventilation grilles on your floor, your ducts are most likely located in the floor.
On the other hand, if your ventilation grilles are on the ceiling, your ducts can be found in either the ceiling or walls. The size of these ducts can vary depending on the airflow needs and local regulatory requirements. Now, let's talk about the three most common places where vents and grilles are located in a house. The first is the supply grilles, which carry treated air to each room. These grilles are responsible for heating or cooling a room to the desired temperature based on the thermostat settings.
Depending on the type of HVAC system and construction of the house, these supply grilles can be found on the ceiling, floor, under windows, or on outside walls. In some cases, you may also find smaller ducts located in the center of the roof between floors. These ducts are fed by larger ducts and are responsible for maintaining proper air pressure within the system. It is important to note that closing off supply to unoccupied rooms may seem like a good way to save energy, but it can actually lead to increased air pressure in the duct system and contribute to larger duct leaks. When it comes to the indoor air handler, the supply ducts act as the arteries while the return ducts act as the veins. The return ventilation ducts are connected to the return ducts, which draw air from interior spaces and bring it back to the heating and cooling system.
This is why it is crucial to have proper placement of return ducts in a home. One way to ensure energy efficiency and lower utility bills is by placing return ducts on interior walls. This helps to ensure that only indoor air flows through the ducts and into the HVAC units. Not only are these locations typically closer to attic supply ducts or walls, but they also help keep rooms cooler. It is important to remember that air ducts and ventilation grilles are integral parts of a home's HVAC system.
