<![CDATA[My HVAC system is in the basement.]]>My HVAC system is in the basement. Circulation isn't the best. In the summer, it can be quite cold downstairs and warm upstairs. I bought a fan to help circulation.
Question: should I position it upstairs to push down the warm air, or should I position it downstairs to push up the cool air?

If you don't want to run the AC all the time, you can circulate the air in the home with the fan mode. Might normalize the temps a bit?

Are there dampers on the ducts? look into opening the dampers on the upstairs ducts. if theyre wide open, look into closing down the dampers on the lower ducts.

if its old and there are no dampers then try to find a way to blow the cool air up, while having a second way to let the upstairs air come back down. is there a return upstairs? change the filters on all the returns.

We've got a single air duct in the top floor so it doesn't cool very well. I put a fan at the top of the stairs to move the hot air down to where the thermostat is. Works pretty well, but the climate in Victoria pretty mild.

I think @ifixcoinops has dealt with this kind of thing.

can you tape/bind a plastic tube of some sort to it? then I would recommend positioning it downstairs and blasting the cooler air upstairs through the "tube" (tube can mean a plastic sheet taped together into a tube and then inflated by the fan)

Cool air goes down because it is slightly denser than hot air. So a fan will be a little bit more efficient moving air with higher density. But I'm afraid the difference will be tiny.

Or open a window high up on the house, and blow the hot air out. And the cold air up.

That seems like it would work.

I'm honestly not sure which would be more effective...but you might buy another fan, and do both.

Warm air rises naturally.

I would try to push the cool up from the basement
