So far, so good. I haven’t had a chance to use it very much, but it runs quietly, and puts out heat and produces cool air. I give one star for delivery because it too THREE tries before I received a unit that wasn’t damaged! Customer service at Home Depot was great concerning reordering a replacement, but the shipper sucked!

condensate leaks
The 1/2 condescending line started leaking after 2 weelks of professional installation, and flooded my customers nail shop, we had two replace it two times and finally we had to replace it with 1/2” pvc scheduled 40, seems like the unit was stored for a lonng time and the lines got tosted and break super fast

    This unit is great. I installed it according to the instructions and its performance is superb. It’s so quiet — both the condenser and air handler — I can hardly hear it. It cools my workshop quickly and dries it nicely. You need a gauge set and vacuum pump. You also need an adapter for 5/16” fitting if your gauge set is for 1/4” automotive. The price was amazing at under $1,000.

    It has only been 3 weeks since I had the unit installed and we love it. Even on the hottest days (96 degrees) it has kept the shed cool and comfortable, while we continue to prep the shed as an added recreational space.

    works great!
    Very happy with this unit. High 20.5 SEER makes it efficient. Both indoor and outdoor units are very quiet. Hardest part of the installation was putting in the UVC strip accessory. I also used the Pioneer linset cover set. Finished the job nicely

      Unit comes well packaged. The instructions are a little sketchy, but doable. I had to add a condensate pump due to my install location. Wi-Fi should be standard, but the Wi-Fi modules are out of stock everywhere. Cools wonderfully. Wish there was a service port on the high side. Wish they used 1/4 flare for the low service port like the rest of the world. Had to buy a 5/16 to 1/4 flare adapter to add some 410 since I used a 25’ line set. Makes our bedroom super cold:)

      Super Quiet
      I bought this unit to cool our master bedroom. I am a light sleeper and this is super quiet on standard low fan mode, it has a quiet mode that is almost silent. Instructions were straight forward and easy to follow. I am very happy with this 9,000 BTU mini split and will be installing an 18,000 BTU in the dining/living room as well. It will be another Pioneer.

        Relatively easy install for DIYer.
        I'm a DIYer and this install didn't seem overly difficult and was not. The installation instructions are thorough and easily followed. Hanging the inside unit requires planning and forethought as you can hide the hole or have it extend beyond the inside unit. I hid the hole for the lines so attaching the lines and making the necessary bend took a little extra time. I hung the outside unit and shortened the lines for a clean professional look. The unit has been in operation a few weeks and has worked great.
