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

In total I have purchased 5 of these units through Amazon. They came on a big pallet and were boxed perfectly. They are an amazing deal. I opened up one unit because I thought it was bad. In reality I had a bad neutral wire in the romex wire I ran and the unit was fine. I was very impressed with the components. The wall unit looks very nice. We have a Mitsubishi Mr. Slim at work and its very industrial looking. I think the Pioneer in much better looking and I love the way the LED display shines threw the plastic becoming invisible when you don't want it. It's very quite and sips electricity. I replaced an old central air system with these units and the difference is unbelievable. I went from over a 120 kWh to just above 80 kWh for a day. In my opinion the best thing is being able to cool the bed room at night independently from the rest of the house. Now let's talk about installing these units. (This is just to give you an idea of what it required. It's not a guide.) Apart from the obvious stuff here is some of the things you should plan for. 1st. You need to install a breaker for each unit. You absolutely should not do this if you don't know what you are doing. 2nd. You need to run the romex wiring to each unit. Your local building codes need to be followed. 3rd. You will need a disconnect box at each unit. I got mine at the local big box store. I have seen them as low as 8 bucks. I also bought a whip (flexible shielded wire that goes between the disconnect box and the outside unit) for about $9 each. 4th. A bracket or concrete pad to mount the outside unit. I made my brackets myself with some hardware and angle stock from the local metal yard. 5th. You need to cut a 2 inch hole through the side of your house. For my wood house I used a hole saw kit from H.F. If you have concrete or brick you may have to rent the tools to cut the hole. 6th. Install the line set between the inside and outside units. If you want to cut the lines to the correct size you will need a pipe cutter and a 45 degree flaring tool. I bought this one: " The Rothenberger 222601 Universal Flaring Tool " If you have never done this before watch some YouTube and practice a little. Connecting the copper lines is a critical step. If your system leaks it's most likely one of you connections. I would highly recommend some sealant for your connections. I used this one:" Nylog Gasket/Thread Sealant " Pioneer also sells there own brand of sealent on their website. Be very carful bending the lines. Don't make the bend all in one spot spread it out. 7th. You will need to Vacuum out the system to get all the air out of the lines. You will need some AC gauges and a vacuum pump. I got a very nice set a H.F. for about 45 bucks with a 20% off coupon. I also got an adapter for 410A Freon. 410A freon adapter: " Yellow Jacket " Vacuum pump: " ZENY vacuum pump " In conclusion this review is for the air conditioning units themselves. Some of the other reviews may have better info in regards to the manufacturer and support.

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.
