If you want to improve the air quality in your apartment with your central heating and a/c method here is a little trick on how to do it; I discovered this trick some years ago and it honestly works great! The trick is to close one air vent in a room that you are not using! By doing this it will make the air flow harder through the other opened air vents in the house.
It is a way to get better air flow and also save a little extra on energy expenses because your apartment will be cooled or heated a lot quicker! Also whatever you set the central control equipment temperature at will be reached and stay there longer so the central heating and a/c methods do not have to run as often during those really cold or really moderate mornings! It honestly helps a lot.
I found out about this little tip from a heating and a/c specialist that I had in the old town I lived in about twenty years ago. They gave me this little tip to improve our air flow and save on energy. At first I remember thinking that this guy was nuts, although I gave it a try and it honestly worked! So ever since that day I do this trick all the time now. If you do not have a room in your home that you don’t use that has an air vent, what you do then is open a room which you are not going to be in for a while. Then trade off the air vent closings as you proceed.
