Hello everybody, just bought a new to us house out in the country. It sits on 1 acre and is about 2500 sq foot ranch style house. I was wondering if anybody in the northwestern portion on Illinois might be able to share information on their system? Like who installed it, approx. cost and if you really like it or not. Right now we have a propane furnace and no central air unit. Just looking for any information that you got. Thank you in advance.
