Adjusting Cold Air Return VentsOur last post was all about adjusting cold air return vents in the fall and the importance of having enough of them to ensure excellent air circulation within your home. This post is really just a reminder to adjust your vents for the coming heating season.

Most people have air conditioning and in modern homes there will be a hot air return vent located near the ceiling just above the cold air return vent which will always be at floor level. You will also only find these hot air return vents on the second floor of two story homes since hot air always rises and at the ceiling level in one story homes. In the spring you may have closed the bottom cold air return vents which forces the air return to the furnace to be drawn from the ceiling were the air is hottest. This improves the cooling effectiveness of your system and provides a more comfortable environment in your home.

Cold air as you may know falls to the lowest levels while hot air rises.  By closing the bottom vent you are forcing the hot air to be drawn into the return system to be cooled by the air conditioner. Opening the cold air vent in the fall allows the cold air to be drawn to the furnace and heated.

Adjusting Cold Air Return Vents

Our cold air return vents actually have a lever that allows us to open or close the vent depending on the time of the year. It is a small lever that you can push up or down depending on what you want to do. Some homes may not come with these kinds of vents so home owners may need to place a magnetic cover over the vent to prevent air from entering.  Make sure that you are covering the cold air vent at the floor level and not the one at the ceiling. You would only do this in the spring when you are about to turn on the air conditioning. If you do not have a hot air return vent at the ceiling level, then do not cover your return vent, since the furnace will not receive sufficient air to circulate.

Winter Time – Open Your Cold Air Return Vents

Once winter comes around, and you are now heating the air, you want to have the cold air which is at floor level drawn into the air return system at the floor level. It is time to open these vents if they are closed and allow the cold air to return to the furnace to be heated by the furnace. Since cold air is so heavy, it will automatically flow to the lowest level into these cold air return vents and to your furnace.

Why Should we Open and Close These Vents

There are a couple of reasons. The most straightforward reason is that you want the air to flow in an optimum way and either cool or heat your home as fast as possible so that you are comfortable. Another reason, which is becoming more and more important as the cost of energy increases, is that you want to save as much money as possible by reducing your energy foot print. By using your homes air circulation system efficiently, you can actually save money and reduce your annual costs to heat and cool your home.

In the winter time also utilize the suns rays to heat your home in the day time and close the blinds in the evening to provide that extra layer of insulation around your windows. The reverse would be done in the summer time were you want to prevent the suns rays from coming into the home and heating the house.

It Only Takes a few Minutes
