Pioneer Air Conditioner WYS012A-20 Wall Mount Ductless Inverter+ Mini Split Heat Pump, 12000 BTU-110/120V

I had some concerns about using this air conditioner on a mobile trailer. Those concerns have been laid to rest. I am happy to say it has worked perfectly. The install went smoothly using the direction provided. The quality of the product is top notch. When I started looking into using this I had some question so I'm going to answer them in case anyone had the same question. 1. How loud is this unit? Answer: You can't even hear it run unless the room is dead silent. It is literally the quietest air conditioner I have ever heard. Even the lightest sleeper will never noticed when this thing comes on at night. 2. How many amps does it use? This was my biggest question since I was using a inverter generator to power it. At it's maximum it uses 10.5 amps. My generator has a screen with amps and volts on it. The best part about this air conditioner is that there is not spike when the unit comes on. When first started it uses about 4 amps. As the compressor speeds up the amps used slowly go up until it maxes out. With most air conditioning units there is a big spike when the unit kicks on and that requires you to have a much larger generator to handle the surge when it starts. Not this one. 3. Will the compressor vibrate a lot while running? I mounted this on a platform on the back of my trailer so I had a concern that the outdoor condenser unit would vibrate and transfer noise into the trailer. It absolutely does not. This thing runs so damn smooth that you can barely feel it running if you put your hand directly on the unit. You can tell this is a quity product the minute you fire it up. I actually got scared at first because I didn't think it was working. That's how quiet it is. I hope this review helps other who are thinking of using this for a tiny house or other trailer application. I wouldn't hesitate to purchase it again. I have even had people comment that they will be buying one when their current A/C goes out. Great product. High quality.

I hate people telling me what I can't do. I want to live in a society that is always trying to help others do everything, from medical help to "holier than thou" HVAC work. Programmers have put open source software into everything like TVs, refrigerators, thermostats, electrical grids, airplanes, and everything else digital. Why can all other professions have the same sharing attitude? I decided to install this myself in a small, 720 square foot decently well insulated home. This was my first time ever working with HVAC and so far it seems to have worked great. It cools off beautifully. The first thing I have to say is that the instructions are written very well. The only part that seemed understated was the head unit wiring. It's not hard but I didn't find the instructions clear on my particular model. I had trouble pumping a vacuum during my "tests" before install. I didn't even come close to tightening the copper properly. The instructions warned several times about "over tightening". I waaay under tightened. With the proper torch with a torch wrench, I had no problems. I pulled a vacuum, waited for a half hour, and filled the system with refrigerate as directed by the instructions. It worked great. Running the copper lines is the most difficult and nervous part. I was very careful, and I recommend two people help with this. The instructions are great. But there are a few things that caught me by surprise: - The indoor unit just clings onto the bracket. If feels strange, but it looks great. - The drain line seems a little short still. - It came with a small bag of "plastic" something and I have no idea what that is for. The instruction made no mention. My local discount tool place sells torch wrenches for $20 and crow foot wrench heads. You need a large head ( I believe 1") for the large line. The only place I can find that sells those is Amazon. Search for Crowfoot Wrench Set. Should run about $20. ***You need this!*** Since the heat pump mode operates at a high pressure, it's very important that it's properly tightened. - AC Refrigeration Pump (can be bought on Amazon for about $130) - Mini Split adapter fitting. (the pump is usually a different size then minisplit) ($15) -Torch Wrench ($20) -Crow Foot Wrench Set ($20) *You need this* - HVAC flaring Kit ($35) - Hole Saw ($20) - Pipe cutter (for copper) ($10) - Condenser bracket/Mounting bracket or pad ($45) - Line cover kit ($45) - Electrical AC disconnect ($10) - Electrical wire - Pipe sealant suitable for HVAC lines. ($8) So your'e looking at around $350 if you were to buy all the extra tools and parts yourself. The electrical, with a shutoff by the unit costs about $30 for all the parts and wiring. I've been running it on "eco" mode and it keeps the place cool on 100 degree days. I can easily get the house down to 67 if I crank the system on high. And that's it! I'm happy so far, seems very well engineered.
