How do I close the air intake on my furnace?
Closing the Supply of Air from Outside
By blocking it, you could strain the system or, in the case of an intake serving a furnace, cause negative pressure that causes fumes and carbon monoxide to back up. That being said, you can safely close an intake vent by sliding the dampers into the closed position.
Should vent on side of furnace be open or closed?
Keep vents open. Yes, even in rooms you don’t use! The more vents you close and the longer you keep them closed, the more likely you’ll experience the problems above. Leaving vents open will also save you more money on heating bills and furnace repairs.

Do all furnaces have vents?
Most home furnaces will be able to “exhaust” vent pretty easily, but sometimes the “in-take” vent installation requirements can not be met, this is common on many town homes and row housing where there is only one or two exterior walls and many items are already exhausting to the exterior.
Does furnace pull air from basement?
When the furnace fan comes on to push cold air through the duct, the hole you describe would pull more air from the basement than from the rooms. As the system tries to push more air into rooms that are not losing air, resistance would build. The result is you won’t get the cooling comfort you seek.
Can a furnace be in a closed room?
There is ample airflow in these enclosures, so the furnace gets appropriate ventilation and combustion air from the rest of the house or through grills in the surrounding floors or walls. Furnaces should not be housed in sealed or closed rooms for several safety and health reasons.
Can I put my furnace in a closet?
