    The manufacturer has determined what size the duct should be. Reducing it will inhibit air flow and can contribute to the sweating you’re experiencing. Cutting costs doesn’t save money.

    I agree. A repair is impractical if not impossible. Given the age of the unit you should negotiate on the price of the house because it will need a new air conditioner soon.
