Can I Add Multiple Air Handlers to a MrCool DIY Condenser (Updated 2020) - Ask the Expert Episode 220

In 2019 someone asked us, "Hey Dan, is it possible to connect multiple air handlers to one MrCool DIY condenser?"

A year ago it wasn't possible to connect multiple air handlers to a MrCool DIY Mini Split. But the MrCool DIY Multi-Zone has now made it possible. In fact, you can connect up to 4 air handlers to a single MrCool DIY Multi-Zone condenser.

    Do I need to install a two-zone DIY at the same time (both air handlers) or can I install the 18K and wait a year for some work to be done to a room then install the 12K?

    (FYI, my wife and I have started to watch your videos for fun. You do you, great job)

    If the 18k air handler is at least 50% of condenser capacity (which it seems like it should be given that the other air handler is a 12k), then you can wait to install the 2nd zone later.

    Thanks for the compliment! We're glad you enjoy the videos.

    How well do your units cool in the upper peninsula of Michigan????

    Given the latitude, basically all of the air conditioners and heat pumps we have in inventory would cool well in Upper Michigan.

    I have a 36K BTU Mr Cool DIY I bought from you guys last year. I understand about the new multi-zone option for new DIY units. Can you clarify that only those will work for multi-zone, or can I add another air handler (somehow) to my current unit... got the one (4th gen I think) with USB stick for MR Cool remote app functionality/control. Thanks!

    Yes, I can confirm that any DIY you bought last year will NOT work in a multi-zone format. For multi-zone, you have to specifically get the MrCool DIY Multi-Zone.
