Ductwork is somewhat larger than with other furnaces because geothermal systems move about 40% more air than fossil fuel systems of similar heating capacity.
Dwight:
I didn't know this, nor did the geo company say anything about this when they quoted me a system. They were going to use the same ductwork.
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.
