I recently bought a new house with a basement and had a furnace guy over to do a check up. One thing he recommended was to put a vent in the cold air return and that way I could siphon the cooler air from the basement to the rest of the house by using the fan instead of the a/c. Does anyone know if this would work well? It seems logical, but before I cut a chunk of tin out of my cold air duct I'd like to get a 2nd opinion from all of the professionals here (what am I thinking!!!). Here's a few photos: Where I was thinking of putting the air vent  The air vent I planned on using

I suppose it would work, but I have never done it on any installs yet. your vent would close anyways, Not much to lose if you do it yourself. you might not circulate as much air in the rest of your house with it open though. just remember that any air you push into a room, just as much air has to come out of it. YMMV. Dan |
After a second look (paying attention this time) I stand corrected.,Also I wonder how that would effect the volume of air being returned from the upper floor/s. |
