This is interesting. Thanks a lot Tony. I'm going to do some research on filters and get ones that allow the maximum air flow, and I'll report back In a day or two to tell you if it helps or not. I still don't see what I can do if it is a balance problem. Is there a away of fixing that? Who do I call to look into it?

Hi,
You did not answer yet whether the problem came with the new furnace.
If it started happening with new furnace maybe they sized it wrong or
after install. they did not tweak the system well.
I am a retired EE from Honeywell, not an expert on HVAC. Good luck.
