Ceiling Return Vs Floor Return

Either type of register ceiling or floor can be used for this as long as the need for the area or room is matched.

Ceiling return vs floor return. The basement one should be on the floor not the ceiling of the basement. Simpler for them i guess. Cold air returns floor or ceiling. Grilles are found in residential ceilings and walls but a company may install them in floors in certain cases.

In the upper stories of the house the return air duct openings on each floor should be approximately equal to the sum of the hot air outlets. The air return is a grille that serves one purpose to pull air back into the central heating and air system for reuse. Most of what i ve read indicates that both the fresh air supply vents and the return grilles should be located high up on the wall or on the ceiling. If the supplies are in the ceiling its better to have the returns low.

Supply registers are the vents that deliver warm or cool air from your central heating cooling system to each room. My recollection is that returns for central a c are usually placed by the baseboards near the floor. Depending on the system setup a home may have one larger return grille or several small ones throughout the home. It will return 23 80.

But some preliminary back and forth has me thinking that my hvac contractor would like to put the supplies on the floor. What is the difference between supply registers and return registers. Floor returns number rounded down towards zero to the nearest multiple of significance. But an a c contractor is suggesting that my 1954 house needs at least one more return in order for the air to circulate and proposed a 14 square grill in the ceiling of my hallway.

If the supplies are on the floor then the return being high or low makes little difference.
