  • Mini split unit
Great product. If you are mechanically inclined it’s an easy installation and setup. If not seek professional assistance. Comes complete with all necessary equipment and parts.

  • Excellent machine
Color: White Size: 12000 BTU - 110/120V
We’ve had this now for almost a year and we are so glad we ordered it. These work so good for the summer time as well as the winter time. We are in an upstairs apartment and the mini split keeps excellent temperature

  • Pretty great so far
Color: White Size: 9000 BTU - 110/120 V
Great so far. I'm using this in a 250 square foot attached garage with a concrete floor. I insulated the ceilings. The back wall is insulated, the garage door has insulation built in. The side walls are uninsulated have no windows. I waffled quite a bit on whether to get the 9000 btu or the 12000 btu system. There isn't really a reason to choose between the other based on price. I read about the risk of picking too large a BTU, since the system might have to cut on and off. However, this is an inverter system so it operates in a BTU range. I you compare the 9000 and 12000 btu spec sheet, the lower BTU range is only a few hundred BTU's apart which means the 12000 system should operate very nearly like the 9000 system on a mild day. I went back and forth quite a bit on the BTU sizing decision. It's hard to decided based on the various possible factors what the perfect size is going to be. From what I can tell, I don't think it's going to matter in my case, except, perhaps on the colder winter days. I fully believe this will put out plenty of cold air and will be fine on the hottest days of the year, but I'm curious to see if that'll be true of the heat. If I had to do it again I'd probably go with the 12000 BTU unit I guess, but I live in warmer climate so winter isn't really what I bought this for. Also, I can always just plug a space heater in for the occasional super cold day if needed. I did see on the spec sheet that the EER rating on the 9000 BTU was higher than the 12000, even though the 12000 has the higher seer rating. Seems like that might mean the 9000 is slightly more efficient at cooling than the 12000 model. The installation was reasonably ok if you're handy. I had an electrician do the wiring to a shutoff box outside and had an A/C guy do the evacuation. I installed the outside unit on some of the exterior mounting brackets sold for mini-splits. The hardest part was drilling a 2.5 inch hole through my hardiboard siding. I think if I had a vacuum pump I could have done the line evacuation myself. However, there was a nick in one flared end on the kit that was sent with this unit. It didn't cause me an issue because the A/C guy quickly reflared the connection. But, it would have postponed the install so I could deal with it if I was installing alone, or, if I had gambled that things were ok it likely would have leaked all the coolant out after I installed it and I would have had to pay an A/C person to come out and recharge the line and find/fix the leak. This unit looks great on the wall. It's completely quiet outside. I run it all the time and my last electric bill didn't appear to go up much, but it hasn't gotten consistently hot yet. The setting to alternate the fan direction is good. The "auto" setting is a bit twitchy. Sometimes it runs A/C and then blows heat a bit later on or vice versa, but that could be somewhat related to temperature changes outside. ... show more

Color: White Size: 12000 BTU - 110/120V
Bought this unit in mid October of 2019. The weather got super cold too fast for me to install because I worked 9 months straight, 12 hour days, 6am to 6pm and that doesn't leave me feeling motivated or with a lot of daylight to install this thing. Early 2020 I was able to start this as the days were staying brighter later. I followed the install manual to the letter and later had my coworker vac the lines down and open the service ports. After trying this unit for about 20 minutes (fan spinning, compressor never kicked on) the unit began smoking. I quickly pulled the local disconnect and my coworker thought maybe that I had not wired the unit up correctly. This wasn't my first wiring rodeo, but there is always a chance I missed something. Turns out it was all setup correctly. So begins the 5 week email chain (including pictures, etc) back and forth with Parker davis (pioneers parent company) and the communication was abysmal. The guy I was going back and forth with said my email went to his trash bin for some reason. He then said he woyld send me a new pcm board. A month went by with no communication and I contacted him again asking if everything was still a go on the new board. He responded with "yes, the board was on back order and it should be arriving to you within the week. Board arrived. The screw holes were chewed up like they had pulled the board from a used unit (back ordered?) and there were rub marks along the metal on the casing. I installed the new board and we were off to the races. I fired it up and hoped for no smoke. It worked this time, well i mean it didn't smoke this time. The outdoor fan kicked on and went inside. The air seemed cool coming out of the fan, but it was actually just circulating the room temperature air. I tried it in heat mode, the fan reversed and started spinning the other direction (as it is supposed to). The indoor unit fan never turned on, or if it did, it was so slow that I couldn't notice. Called a service tech to come out. He checked all the things that I checked before finally calling tech support. After about an hour of troubleshooting, the tech and the tech support tech deduced that the 4 way valve isn't working properly. So now, i have a new 4 way part on its way for a unit that has never run correctly from day one. The hvac tech said "i can come back and braise this on for you, but it will be a little expensive." I asked about warranty and he said "they will warranty parts, but not service." Less than a year old and I am paying for replacement parts to be installed on a defective unit? Last pioneer I ever deal with. Super disappointed. Fast forward to October of 2020: called customer service and please with them that their product hasn't worked from day one. Asked if there was anything they could do. They checked with their supervisor and offered me a new outdoor unit for around $200 shipped. I accepted and it was delivered in reasonable time. I installed the unit and it works great. It is pretty warm here now and at 77 degrees set point, my garage feels comfortable on hot days. In the winter, I want it to run pretty low. Just cold enough that my outdoor fridge doesn't freeze over. The lowest set point is 62 degrees. So it runs non stop in the winter, but the fridge didn't freeze. Had no issue with snow getting in the way of the outdoor unit and it never had any faults. Ran right through cold and hot temps ... show more
