Cold Air Return Basement
I m thinking about adding a cold air return near the bottom of the floor and uncovering the vent.
Cold air return basement. I m assuming because cold air sinks and the ceiling isn t insulated. That is to say the fan can only push so much air whether you re heating or cooling and your unit will draw the same amount of air back into the system. You can warm the basement by cutting a hole in lower cold air return of the furnace to improving the air flow. Every house should have proper air return throughout the house including the basement.
This will draw the cold air off the basement f. What is different in the basement is that most of the ductwork is on the ceiling. Another thing he mentioned that i would like to discussed was that the only way i can have a cold air return in the basement was if i put a 5 dia insulated flex duct from the outside fresh air intake and bring it into the basement and loop it up like a u this way fresh air is introduced will balance out the pressures and the cold air return can circulate fresh air through out the house. The air return allows the air conditioner to draw air back into the system and is called make up air.
Unlike supply vents return vents do not need to be cased in metal. Without return air ducting as in your basement much of this cool air may not be drawn back to the furnace resulting in stale or damp air in that area of the home. Ensuring good placement of cold air returns is critical to ensure proper distribution of air flow. More than often this problem is caused by improper air flow in your home and more than likely it s your cold air returns.
Believe it or not every room including the basement should be the same temperature. Even with the vent closed that area of the basement stays pretty cool even in the hottest part of the summer. By cutting a hole in the return. There is no cold air return.
Essentially that allows the warm air to circulate better. If you leave a cold air return opening on the ceiling it will simply steal all the hot air from the ceiling and return it to the furnace and the cold air on the floor will never move. The basement is no exception to the rule. Cut into the cold air return that is on the ceiling and drop a duct down to the floor.
They can be placed into staircase cavities stacked closets that run one on top of the other or in stud cavities in the wall.
