thanks for the input the house is roughly 2600 sq ft 3 stories 5 bedrooms dont know if that is considered huge in the scheme of things but a friend of mine who is in hvac was supposed to run my info through his software to see if that was the right size or not he was hesitant to give me advise on this because he is totally opposed to buying things used and wants me to get a new system i posted on here because he is out of town for a week and didnt know if i should jump on the deal before someone else but from what your saying if the condenser is the right size for the size of the house the evaporater coils are what needs to be matched to the furnace. correct? thanks again Luke
