    134a is used for comfort cooling...in autos and in centrifugal chillers. Just not in residential.

    OP, any reason why anyone would want to buy a 13 year old a/c condenser for what you're asking for? Do you and any potential customer you have a favor and take that old thing to your local metal recycling yard. Get some lunch money and move on.
    • Electricity makes refrigeration happen.
    • Refrigeration makes the HVAC psychrometric process happen.
    • HVAC pyschrometrics is what makes indoor human comfort happen...IF the ducts AND the building envelope cooperate.


    A building is NOT beautiful unless it is also comfortable.

    Tear out the coil and take it to the scrap yard. No one will pay that for an old unit.

    This is a new one. Trying to sell your old condenser while asking a question. This should go in a "best of" section on this site if there was one. Quite ironic I saw this post. We did a changeout last year on a system and took the old condenser to our yard to scrap. Never got around to it and one of our customers lost a compressor and he ended up with this equipment. Got a call yesterday for no cooling on this house. Got out there this morning and the compressor is locked up on the unit we sold this guy. He paid $ for the POS last summer to save a few $$$ and now he's gonna be buying a new on tomorrow.

    I like DIY'ers. They pay better to fix.
