Hello, I have an old house and the gas furnace is just about as old as the house. The problem I have is that the temperature on the first floor is a lot higher than the basement. I did try to close some of the vents on the 1st floor and open the ones in the basement but I still have a big difference.

Is there something that can be done?. do I need to install something to re-circulate the air?.

I do not have air conditionning so this might be a good idea to install one. But I would like to use the existing piping (docks). Am I looking at too many things at the same time ?

Any help would be apreciated.
