The answer i generally give is no but without knowing how much return air you have in your house or how much you ll be blocking the return its impossible to tell from here.
Can you put furniture in front of air return vent.
It inhales quite a large volume of air.
When you block a vent with a textile the entire ac has to work harder to pull air into the system and to push it out again.
This is one of the main reasons why some homeowners believe they can block air return vents with furniture.
This extra work takes a toll.
The short answer to this question is no vents are there to provide for a necessary free flow of air.
Yes if you take into account a few considerations.
Move the item further away.
Block that flow and your home will run sub optimally and you could even cause damage to your hvac system.
Your ac will wear out faster and will consume more energy.
Renay you can place all the furniture you want in tront of a return air vent just be sure you leave a little room for air to go under around or over the top and don t place a piece that the vent.
I want to place a piece of furniture in front of a cold air return vent.
As long as you are not on top the vent and the bookshelf is not closed in in other words there is open space on each end you should be fine.
Disrupted air flow may also cause humidity issues and refrigerant issues both of which are harmful to your iaq and your hvac system.
This reduction in return air can starve your system and cause the furnace air handler to overheat.
The vent is close to the floor.
1 don t block the airflow.
There would be a gap of at least 3 inches between the vent and the back of the furniture.
Should be okay as long as you are not putting the furniture directly up against the return blocking its cfms just make sure that your return is not blocked from intake airflow.
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.
If you own the house and can put an intake in the basement that will help but you should be ok.
