Comparing Performance of Minisplits

fourforhome | Posted in General Questions on

Is the Fujitsu mini-split still at the top of the performance charts (for 1:1, compact duct)?

The new Fujitsu aouh18luas1 has lower COPs at 47° and 17°F.

I see the Daikin RZQ18TAVJU has a minimum capacity @47° of 10,500. That’s only a 2.6 turndown ratio. It does have more capacity @5° than the similar-sized Fujitsu, 23.6k vs 17.5k.

The Mitsubishi NAXSKS18A112AA has a minimum capacity @47° of 8,100, far behind Fujitsu @ 3,100. It looks like the Mitsubishi drops off faster @ 17° to 13.9k compared to the Fujitsu @ 19.6k

Are there any new models that beat these numbers?

    You mentioned NAXSKS18A112AA as being Mitsubishi but that is an American Standard unit. Can confirm the Mitsubishi unit and stats?

      NEEP has it as!/product/28966/7/25000///0
      American Standard / Mitsubishi Electric M-Series

      I thought all the "/Mitsubishi" ones were just rebranded Mitsus.
      What's Mitsubishi's best?
