    Lower efficiency and capacity.
    Also some manufacturer's will void a warranty on a mis-matched frankenstein system.
    Do it right, or don't do it at all.

    Loss of capacity.
    uses more electric then a matched 13 SEER system.
    Some manufacturers void compressor warranty.(They require the indoor coil model and serieal number to get compressor warranty)

    Here's a report.

    It is NOT a 10-seer air handler, it is a 10-seer evaporator coil.
    Air handlers have nothing to do with the mismatch we are discussing.

    Were I not retired & there, & you absolutely could not afford a 13-seer matched coil, I would have reconditioned a 10-seer condenser for you.

    Have you already replaced the condensing unit?

    Why are you replacing the 10-seer condenser?

    What was the diagnosis data told to you or left on the invoice?
