    2-zone mini split with only one evaporator

    For a mini-split install, with a 2 zone condensing untit, would I be able to install just one evaporator, then add the second evaporator at a later date? The first evaporator will be 9,000 BTU, the second one 12,000 or 15,000 BTU.

    I am an A/C contractor in South Texas.

    It depends on the brand. Ask your supplier if the brand you use will allow it.

    Assuming that the BTUs on the evaps are proportional to the condenser's BTUs, yes. Also assuming that the brands are the same, yes.

    Mitsubishi says multi zone units need a minimum of two evaporators.

    There = not here. Their = possessive pronoun. They're = they are
    It's = contraction of it is. Its = the possessive form of it
    Too = also. To = expressing motion. Two = 2
    Then = after that, next. Than = indicates a comparison.

    Like the others have said it really depends on the brand. Ive done what youre referring to on several off brand units but i seem to remember I couldnt on a Daikin. It will be in the literature somewhere. Or dont forget about tech support. If youre like me i always totally forget about tech support until after the fact. Good luck

    Ok. Thank you for the quick replies. It looks like maybe a no-go. I will study individual brands. I have used Mitsubishi, Daiken, and Klimaire. The quality seems to be there on all three.
