I believe you switched to geo, correct? If so, was your duct work increased in size? Your system seems to work very effeciently and the way that your system works is how I'd expect a geo system to work, that's why I'm asking.
There are thousands of Geo-systems working just fine that have been fitted to existing homes. The 40% larger ducting is ideal in new construction.
Since Geo-systems move more air you will notice an increase in the "breeze" when directly in front of a register. Do they still call them registers?
