      Q:Does it come with a longer line set? I'm afraid I'm going to have to hide this from the HOA. 25 Foot would be perfect. 16 feet and I have to sneak out at 2 AM and move my fence forward three feet without anyone noticing.

          Outstanding Pioneer Mini-Split AC & Heating System
          After we completed the construction of our 117 square foot pottery studio in our Arizona back yard, we needed to install heat and air conditioning. After much research, we chose this unit. Reviews were great on it, we found it manufactured with quality components and looked fantastic when installed. With the AC on, it puts out very cold air and when we switched to heat, the warm air was very nice. Loved it. Appearance after installation was great. Very Quiet! Hire a AC tech to install it !

            The Best unit ever!!!
            This unit was delivered promptly and was very easy to install ,great directions.I highly recommend the Pioneer 24,000 BTU unit!! We have installed one in our upstairs and downstairs and we are very impressed!!!I would definitely buy again.

              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.

                  Pioneer trusted worldwide, best value here!
                  I've travelled to many tropical countries in Asia, the mini splits are mostly Pioneer and they always worked well. I am a capable diy'r with strong technical skills, my family member is an electrician. After a $150 vacuum pump and a few youtube vids this thing was a cakewalk to install professionally. The Pioneer website provides extremely good tech support via chat. This is one of my best purchases and has saved me thousands of dollars.

                    We put this in the smoking loung of our cigar store. The room is 550sq ft and it works awesome!! Easy to program, easy to control. Still need to connect it to WiFi. We purchased it from here but had a local HVAC company instll. Still need to finish the rest of the wall so I will update photos when finished!!

                      Great system, tricky install
                      So far this mini split is performing well and the build quality is great. My only negative feedback is that the installation guide could use more detail- it seemed to leave some key details out. I'd rather it be twice as long but not leave me guessing. I had hoped to install this completely by myself but had to call in a professional for the final few steps.

                        Review of Pioneer Energy-Star 12,000 BTU heat pump
                        I installed this myself, over a period of three days. Everything went very well, installation was a breeze. Installation was in a 39 foot 5th wheel trailer. With an outside temp of 81 degrees and a 72 degree setting on automatic, the unit only pulls 6 amps, so it should prove to be very economical. Cooling RV's with the 15000 BTU roof units is horribly inefficient and this is the answer:-) The 24 DB interior sound level on this is incredible as you can hardly hear it in operation

                          Tiny remote letters.
                          Love the unit but can't read the tiny remote selections. How about a better remote.
