    Refrigerant piping Usually equals Lineset and in a lineset the suction line comes preinsulated liquid line does not. is this the case?

    Raintight disconnect box....no mention of a fusible disconnect which it should be.

    No mention of Permit...permit costs costs or the pulling of a permit with the local jurisdiction.

    Why an 80% why not a 90%? Where are you located?
    Thanks for feedback small change. Is 90% more edficient? Located in NJ.

    Perhaps I should have said Scheduled, Regular maintenance on your furnace will keep it running
    efficiently for a long time.

    But I have been running into a spate of ecm motors (modules) lately that have failed due to poor maintenance practices and the direct correlation was a failure to change the filter media for sometimes years at a time.

    I suppose the same could be said for any furnace/motor combination with an extremely dirty filter but just something I have run into lately.

    Yes 90% furnace is more efficient than an 80% effiicent.

    Ask any contractor to quote you both if he is just quoting you an 80%

    How big is your house and how did they determine what size you needed. The posted sizes would typically be a 3000+ sq ft home.
