New construction - 2nd HVAC in attic?
Hello everyone and thank you for the great forum. We are in process of building our new home in Chicago area and the builder is suggesting we put our 2nd HVAC in the attic as running vents from basement will eat into space. I used to have another home in NJ and had HVAC in attic. It worked fine with insulated duct work but just curious if it would be advisable to keep both units in basement. Builder stats that he would put the unit in a enclosed room with insulation.
