A Complete Hvac System Includes Ducted Returns Building America The basic functions of return air vents. circulate air: the primary role of return air vents is to facilitate air circulation throughout your home. they draw in the indoor air and send it back to the hvac system for heating or cooling, ensuring consistent temperature regulation. maintain air pressure: return air vents help maintain a balanced. Issue 1: blocked or obstructed vents. blocking vents can cause your hvac system to work harder and become less efficient, ultimately increasing your energy bills. to solve this issue, ensure that all your vents are clear of obstructions and have proper airflow. issue 2: supply and return vents too close together.

That means that a 100,000 btu furnace requires 7 standard sized cold air return vents (with cold air return grilles, of course). note: the exact calculations are made with the help of manuals by the air conditioning contractors association. those have charts for specific vent sizes, pressures, and allowed airflows. Return vents should be located in centralized rooms, such as larger living spaces or family rooms. these central locations allow return vents to efficiently pull air from the house and into the system. in most cases, you'll find return air vents located on a wall instead of the floor or ceiling. Best place for supply air vents. the best location for the supply vent is on the wall, right under the window opening. however, ceiling installation and floor installations also work a treat as long as your heating system has sufficient btuh capacity and fan. the location of the air ducts may limit your choice.

The main purpose of a return air vent is to suck the air in your home back into the hvac components. this is pretty much recycling the air in your home. once it is heated, or “conditioned”, the air goes back in your home’s living space via duct work that ends at the supply vents. for example, in the winter you kick on your furnace. Furthermore, without a return air duct in each major room, the supply duct air has to "push" all of the air in the room out of the way as it makes its way towards you. the return air ducts help pull the air as it is being pushed. an hvac return air can be in the floor, but they work much better on walls up about 7 feet.
