upstairs hotter then downstairs..

I know the basic rule of heat rises.. but how much hotter should upstairs be then downstairs? its like a difference of 15 degrees.. (about 5 steps; split level house) i have tried to close vents down stairs to force more cold air up stairs, doesnt seem to work... could this be an issue with insulation in my attic? Or is this just normal...

could be a dumb question but just wondering... thanks!

If you can (or ask someone else), go up in your attic and measure how much insulation is there.

If it's not enough, the heat from the attic will make your upper floor very warm. Even with the AC on.

That's what was happening to my house. Even with a new furnace/central air and closing the vents in the lower level of the house, it was still hot upstairs and way to cold down stairs. This is a split level too. Turning the ceiling fan on over the stairway didn't help and when there was a cold-air return down there, it made no difference.

Check your insulation and look around to see if the attic is properly sealed. Also check the ventilation in your attic. I have soffits, but the existing batts of insulation were blocking any air from making its way up into the attic.
