Return air vents are generally located near the center of the homes. Older and newer homes often have one register per floor, but homes built from 1960-1990 may have a cold return air vent in each room.
For heating, the best place to have the ventilation installations placed is on the floor. Heat rises, so having the vents on the ceiling won’t do much good for the room they’re in to heat the ceilings.
Thereof, Where should the return vent be located?
Place your cold air return vents on the inside walls of buildings at the lowest point. The return vent pulls cold air from the bottom of the room and returns it to the furnace to be reheated and returned as warm air. Unlike supply vents, return vents do not need to be cased in metal.
Also to know is, Why heating vents are best placed near the floor? Floor Ducts Heated air is less dense than cold air. … Floor ducts are effective because they deliver heated air at floor level. The heat then rises and continues to warm the rest of the room.
Subsequently, question is, Are floor vents efficient? Though floor vents may not be superb for cooling, they are generally far more efficient for heating. During the cool winter months, heated floor vents disburse the air through the ground, which then rises. This warms the house far more effectively than either ceiling or wall vents.
Also, How do I keep my floor vents down?
To keep floor vents in place, nail or screw them right into the floor. This is easily accomplished with wooden vents, but if they are metal, you’ll probably need to purchase new ones. Another option is to use velcro or double-sided tape.
Where should floor heating vents be placed?
Efficient heating means installing a return at a low point on the first floor, to capture cooled air and return it for heating. Registers that deliver warm air should be in the floor or low on the wall; registers to deliver cool air should be installed high up on the wall. (The best systems may require a mix.)Jul 4, 1992
Is it bad to cover a floor vent?
Covering the floor registers in your home is potentially dangerous if you cover them when using the heating or cooling system. The air pushes through the grates, but the covers block the air from escaping. When you turn the heat up, you push more air through, which raises your heating bill.

What is the difference between a duct and a vent?
Air ducts and vents are part of a building’s heating, ventilation, and air conditioning (HVAC) system. There are two types: supply vents and return vents. If your indoor air handler is the heart of the system, the supply ducts are the arteries and the return ducts are the veins.
Why are some air vents on the floor?
Floor Ducts Heated air is less dense than cold air. That’s why heat rises. Floor ducts are effective because they deliver heated air at floor level. … Floor vents are typically used in homes where the furnace is in a basement or the ducts (the piping from the furnace) travel through an underground crawlspace.
Is it bad to put your bed over a vent?
It’s unlikely but not impossible that blocking a heating vent and causing the furnace apparatus to overheat could cause a fire. Put the furniture over the vent in summertime, and you decrease the overall air flow from a central air-conditioning system.
Can covering a vent cause a fire?
Fire Hazard Perhaps the most obvious (and most dangerous) result of a blocked vent is that it will cause a fire. … When you’re forcing your system to overwork, as mentioned in our first point, you put your furnace at high risk of setting on fire.
Can Return air vents be on floor?
Return vents are usually larger than heat registers and can generally be found close to the ground or in the floor in older homes or on a wall close to a ceiling in newer homes. You will not feel air being blown out of these vents, as they are used to force out the cool air in the room to be reheated by the furnace.
Is it OK to cover air vents?
You could mess with the air flow. Just because you cover the vent, it doesn’t mean your HVAC system knows that. It will keep pushing air to those vents, and if they’re closed, you could cause a buildup of air pressure and insufficient airflow which could damage your system.
Is it OK to tape over a vent?
2 Answers. Whether you tape it or otherwise block it, the effect will be the same and it will not cause any damage to your system; it would be no different than if there was a standard register there that was closed. Unlike duct tape, this will not dry up and will hold the seal.
Where should floor vents be placed?
Floor Registers: Ideal for Efficient Heating Place your registers on the ceiling, however, and much of your warm air will pool in the upper part of the room where it won’t do you much good. Floor registers are typically placed under windows to let the warm air they deliver mix with the cool air coming from the windows.
How do I get my baby out of the floor vents?
If your registers are wooden, simply use a drill or hammer to put them into place. If they are metal, you will need to purchase screw in vents. Screwed in vents will keep your child from taking the register off the floor and keep toys out of your ducts.
