    Thank you.
    I have two Mitsubishi units in my house. My daughter is getting quotes now for her condo. Both contractors recommended Haier units. I thought these were lower quality brands. Have I been mislead?

    Haier is a large Chinese refrigeration appliance manufacturer. I haven't been favorably impressed with the longevity/reliability of their standalone dehumidifier products, but maybe their cooling equipment is better (?).

    Who is going to back up the warrantee, maintenance, & repair aspects of a Haier mini-split? The support chain matters, something the Japanese mini-split vendors seem to have a better handle on in the US/Canada than some of the others.

    The most important thing for efficiency is sizing it correctly for the loads, not the brands. A 13 SEER mini-split with a reasonable modulation range correctly sized for the cooling load can easily outperform a 3x+ oversized 20 SEER model that never modulates.

    Is it being used for cooling-only, or both heating & cooling? Got a model number? Did anybody run a true Manual-J load calculation?
