        When does compressor and fan completely shut off
        ByJun 17, 2026
        1 Answer | 
        Answer This Question

        Hello, The compressor will turn off once the requested temperature has been reached. The fan will continue to run, as it continuously monitors the room temperature and signals the compressor to turn back on if additional cooling is needed. Thank you.

          115 or 230? In the product highlights it says: "Special 230-volt/20-amp electrical outlet required (unit will not work with a standard 115V outlet)" Yet the 3rd picture is 115V outlet and plug, so which one is it?
          ByJun 13, 2026
          2 Answers | 
          Answer This Question

          This unit is 230V - the 3rd image is incorrect as is the socket type. Thank you for calling this out - we will have this updated tomorrow.

            It is now July 8 and you still have 9/17 images showing a NEMA 5-15 outlet. This is very confusing when the description says 230V but images show 115???

                      Great features, but there are no condensate drain holes.
                      Nice unit, and it's a clone of the 14000 wall unit Frigidaire it replace and is currently unavailable. The only problem is it has the same problem the Frigidaire unit has and that is, there are no condensate drain holes. You are supposed to tilt the unit back 3-5 degrees, but with no place for the water to go it just sits in the bottom where it will eventually corrode and destroy the unit. That's what eventually happened to the Frigidaire its replacing. You'll need to either cut slots into the back side of the housing or drill drain holes in the bottom, which I did. Just be careful not to drill into the copper tubing.

                        Not cooling
                        I purchased it in December 2025 and did not use it until summer. This AC blowing but not cooling at all. It is a room temperature air conditioner. Not to mention it arrived cracked.

                          Its great if its not that hot outside. It cools the house but when its over 90 degrees outside, it feels like 80 degrees inside. It only feels cool & comfortable before 2pm when the sun is not intense.
