Pioneer® Hyperformance™ 9,000 BTU 25.5 SEER2 Ductless Mini Split Inverter++ Wi-Fi Enabled Air Conditioner Hyper Heat Pump Full Set

The unit arrived pallet mounted and wrapped. The interior unit was damaged in shipment and Pioneer customer service was contacted and sent a replacement fairly quickly. A pre-paid return label was supplied to UPS the damaged unit back to them.I installed the interior unit onto ½” drywall with 7 drywall anchors rated at 75 lbs each. The interior unit weighs about 30 pounds, so hitting a stud isn’t absolutely necessary as long as the drywall is securely mounted to the studs, is in good shape, and proper anchors are used.The template showing the wall penetration hole center location is sufficient for the horizontal measurement, but is vague for the offset from the bottom since it references the unit’s bottom edge and not the mounting bracket’s bottom edge. Be careful marking/measuring since the bottom of the hole is very close to the bottom of the unit and drilling it too low will leave a little bit of the hole exposed when the unit is mounted.My wall penetration went through drywall and concrete block. I used a 2-1/2” carbide hole saw with no issue. As per the instructions, there should be a downward slope to ensure the drain is pitched properly for condensate drainage.I sleeved the hole by rolling up an IKEA flexible cutting mat into a tube.The refrigerant lines were factory “double flared.” They didn’t look so great, so I cut them off and reflared them using an eccentric flaring tool which worked very nicely. Lots of YouTube videos on proper flaring techniques.I used Nylog Blue on the faces and backs of the flare but not the threads. There is a lot of controversy of lubricating the threads which can cause over torquing.I used a torque wrench to tighten the flare nuts to spec. THIS IS PROBABLY THE MOST CRITICAL STEP FOR THE INSTALL! I was surprised how much force it took to get 40+ ft-lbs for the larger copper pipe nut. The smaller pipe was pretty easy.I could not get the Wifi working. Apparently for this “Hyperperformance” unit, the only app that will work is the ConnectLife app. The Pioneer Airlink and NetHome Plus did not work. To Pioneer’s credit there was a small slip of paper in the instructions that did name ConnectLife as the app to use.I used a wall mount bracket for the condenser since it allows better airflow around the unit and keeps it off the ground.I used a line set cover to hide the piping.I was very careful to vacuum out the line set and ensure the vacuum help for an hour or so.I also was very careful to check for leaks in using soapy water. Note that heating mode runs at much higher pressures than cooling mode, so you may want to check for leaks in heating mode, too.I ran the control/power cord in liquid tight conduit for protection. The control/power cord is the thickness and flexibility of an extension cord, so I was a little uncomfortable with leaving it exposed even though it is said to be UV rated.220V dedicated system power was installed to the exterior disconnect using THHN 12 gauge solid wire in liquidtight.I spent a LOT of time going back and forth to my tool boxes to get various tools. I took my time over 3 days to install it since I wasn’t in a rush. If you think you can do it all in a day, including installing the dedicated branch circuit, it would be a REALLY long day and probably take two experienced people AND having all your tools immediately at hand. I watched dozens of installation videos.Some common items I saw that are very questionable in several videos are:- Not using a dedicated circuit for power.- Not having the disconnect within view of the exterior unit. Electrical code states “Disconnecting means shall be located within sight from, and readily accessible from, the air-conditioning or refrigerating equipment.”- Running “Romex” (plastic coated) power in conduit.- Running the wrong gauge wire for power.- Not using bushings where power enters/exits the unit and/or the disconnect.- Torquing the flare nuts “by feel.”- Kinking the refrigerant line(s).- Making poor electrical connections to the terminal blocks in the external unit.- Improper condenser wall mounting by lagging the vertical AND horizontal supports to the wall. The bracket arms are designed to either hang from horizontal bar OR be used without the horizontal bar and lagged directly into a wall.- Improper clearance for the outdoor unit. Shrubs up against the unit, too close to the wall, etc. impedes air flow.- Cutting the line set too short (<3-4 feet). If the line set is too short, the pre-charge will be too much for the system.- Letting copper burr shavings fall into the line set when preparing flares.- Not vacuuming out the refrigerant lines before releasing the refrigerant.- Improper wall penetration sealing from the outside. Use duct seal compound and/or pure silicone caulk and/or expanding foam. You want to prevent water, air, and insects from getting into the wall.The outdoor unit is very quiet. The indoor unit is also very quiet on low settings and acceptably quiet on med/high settings. This 18,000 BTU unit draws about 1,500 Watts when cooling in high mode. The inverter capability controls the compressor to variable set points based on the cooling or heating demand level to maximize efficiency. This system really delivers very cold air for the A/C mode and very hot air in heating mode!**** Update Feb 2025Still working great in heat mode. Use it daily without issue. Outdoor temps have dropped below 20deg F on a few nights and it still pumps out the heat. Haven't had any significant issues with the unit at all. I attribute a LOT of the success to the proper installation methods and being diligent about the proper vacuuming of the refrigerant lines and flaring and torquing the connectors to spec. Getting everything level where needed, sloped drain, secure mounting and proper electrical wire gauge and breaker are keys.

This unit was installed on a shipping container by a professional after the container was spray foamed. It is awesome. P.S. it runs fine off a 6500 watt generator

What can I say about Pioneer? I wanted a mini split for a outbuilding that we were going to use as an extension of our home. It is just under 600sf with a 15' cathedral ceiling. I looked around, asked a lot of questions from my local HVAC companies. It seemed that most were around $5000 installed. My insurance guy mentioned Amazon and that he got one that was inexpensive and worked great. I searched for a bit and found this one. i contacted Pioneer and spoke to their Tech Dept. They were very helpful and answered all my questions and gave me some advice on which unit I would need for my application. SOLD! It cost a fraction of the cost of my local HVAC company and I had it installed by a licensed HVAC guy for $400. Keep in mind I already had the electrical done ahead of time. This thing is fantastic. Keeps temperature within 1-2 degrees of my setting (it is mounted about 12 feet off the floor, so I use ceiling fans to help circulate the air). Works like a champ. Very quiet. It's winter here, so only using the heat for now. Can't wait to see what the A/C does because the building gets sun all afternoon. Trust me when I tell you, this unit doesn't disappoint.

It only took me a few hours to install and it was straight forward to do. I got up this morning and it was in the high 20's and with the fast heat option it warmed to family room and kitchen in a very short time. The rooms went from the mid 50's to 70 in less than an hour. Very satisfied with this purchase. When youc compare costs, just remember you can get about $500 tax credit too.

Temps in MN are currently -20F and unit is functioning well keeping my enclosed porch heated

This was easy to install, very straight forward following the directions. I waited to get some use before writing this and it works great. I installed in my shop early spring so used the heat and A/C over the summer, perfect. Be careful on the 3/8 line, easy to kink if you try to bend too tight, and the remote is a little confusing for older folks, like me. Extremely happy.

Put this in my garage--tired of freezing. Added bonus is that I can stay comfortable in the summer, too! I got the 10 ft line set and trimmed it to 7 ft. It's controllable via wifi. Only thing I wish was different is that the remote control is IR, so it needs a clear line of sight to the unit face of the unit. Remote is hung on a wall nearby, so it's not necessarily pointed directly at unit, but it does limit your choice of location for the remote. Things I needed in addition: line set cover, 60-amp non-fusible disconnect, Nylog, 10/2 electrical cable, 10/2 whip, conduit brackets for whip, 2.5" x 10" in diamond-tipped core drill bit, drywall saw, masonry drill bits, grommet set, 30-amp 2-pole circuit breaker, hammer drill/impact wrench, orange low-voltage 2-gang outlet frame, wall-mount brackets for outdoor unit, Gardner-Bender MS-1577 electrical cable staples, Hilmor 1963826 Adjustable Torque wrench, vacuum pump & gauge kit, flaring tool, stud finder, level, line wrench set metric. I got all the extra stuff I needed on Amazon for $900 or so. It's quiet, heats the garage from 45 deg to 65 deg in about an hour. It took me a day to prep for installation, a day for installation, and another day for startup, finishing touches. I needed another person to help me mount the indoor and outdoor unit, otherwise it was solo.
