Review: Super happy with this mini split! - I purchased this .75 ton single zone system for my master bedroom which is always hotter than the rest of the house. So, this is providing supplemental cooling to a room. I was lucky to have an ideal situation of having space on an exterior wall in the room so the heat pump could be placed just on the other side, with an electrical subpanel within 10' of the unit. So, very straight forward install. I purchased a 2 3/4" hole saw to make a clean hole on my interior drywall, then used a small masonry bit to make a series of small holes in a circle on the outer stucco wall, being careful to create a slight downhill slope from inside to outside. Some comments about the instructions that come with the unit: - the description of wiring connections refers to colors that didn't exist with the kit that I purchased. In the end, colors don't matter a bit, just make sure the order is identical for connections 1,2,3 and ground on both sides of the control cable. - the manual mentions in bold letters to be sure to plug the drain in the drain tray using the supplied plug on the side opposite of where the drain hose is coming out, since it is designed to support either left or right side drains. I couldn't find any plug, so I called support. They said ignore, it's already installed at the factory, and since I didn't need to change it to the other side I was fine. - the manual mentions to test your drain by removing the filter screens and pouring water into the tray. This is not obvious where to pour the water. Tech support said to pour over the evap coils. My first try I poured a little too far back and water ran down my wall. Then I poured a little close to the front and water ran out the drain line like it should, with no leaks. - the very good news is that tech support is available. I probably waited about 5 mins on hold to talk to a tech, and they were very helpful. Once the physical installation of the indoor and outdoor units was complete and the circuit was run, I called my HVAC friend to come over and complete the install. He insisted that we cut the stock flares off the lines and reflare the ends, as the factory ends are usually flared with too much pressure resulting in very thin flares. Sure enough, his flares were much thicker than the ones he cut off. Also, we found a piece of loose copper in one of the 5/8" flare nuts which would have caused leaks for sure. He then made the connections and used nitrogen to test the lines to 700psi for 10 mins, then pulled a vacuum for 10 mins. Finally when he was satisfied that all air was purged from the lines he open the valves to charge the system, and it works perfectly. I had pondered doing that part of the job myself by buying a vacuum pump and gauges on desertcart but I think I'm glad that I ended up paying a pro to do it instead. There are some hazards that only someone with a lot of experience would know to look out for. As some other have mentioned these units are unbeleivably quiet. If it weren't for the fact that I can see the fan moving on the heat pump, I wouldn't know it was running at all. It is really that quiet. Hopefully this will provide many many years of comfort!
Review: Nice unit, not so easy to install without tools and experience - I bought this to add to the bedroom. The instructions were very thorough with lots of installation hints which was nice since I had never installed one by myself before. A few minor issues such as the wall layout for my model was wrong so I had to figure out where to drill the hole myself. The through the wall hole size that was shown was also a good 3/4" too big, but that helped when installing it later since it did not quite line up right. All the components seem high quality and durable, made in china of course. Be sure to use the special refrigerant lubricant/sealer, RT201B Nylog Gasket/Thread Sealant available on desertcart, on the flange connections when installing the copper tubing, it really does help prevent leaks which are the biggest issue with these units. That is not mentioned in the instructions BTW. Once installed, the unit is super quiet both inside and outside, works fast and seems efficient. The heat function is great, can't wait to try it this winter. Be aware that unless an HVAC contractor installs it, there is no warranty. You will need some special tools such as a calibrated digital torque wrench to the tighten the connections properly, a vacuum pump to clear the lines and possibly some copper pipe flange tools if you need to change the length. Overall it is a somewhat challenging do-it-yourself project unless you have some hvac experience and tools handy. I would recommend buy the plastic covers for the lines as shown in the picture, gives a cleaner and more secure finish. Of course the next one would be easy.........

## Questions & Answers

**Q: How well does this unit heat a room?  More specifically, how well will it heat a roughly 350sqft. space in the winter, in New England?**
A: A 12,000 Btu unit will do a great job at cooling a 500 - 600 square foot room in your northern climate.  However at 15F, the heating ability will not be 12,000 Btu's and might be in the area of 9,000 Btu's.  That might be enough to warm a space that is well insulated, with less than 12 square feet of windows, and probably not a door going outside that can let in a lot of cold air.  

Having a mud room is nice in your area, to keep the very cold air from blowing in while you enter the house.  Windows basically have a R-1 insulation factor, or they conduct heat very well.  

If you get a 18,000 Btu unit, I think it will provide more than enough heat for your space.  Installing a slightly larger capacity unit is OK, in that the unit will offer more off time, where it can take a break on a 45F day, and only run say 15 minutes out of every hour.  Then at very cold temperatures, you would not require running a electric back up heater.  

Then in the summer, the unit could run for a few minutes to cool that space, and maybe as much as 700 square feet, and will go to the low speed mode on the compressor and will run on as little as 400 watts once the room is close to the desired room temperature.

**Q: 1000square feet what size do I need**
A: Depending on what state you are in, and the local outside air temperature when you are trying to heat your room, you might need only 12,000 Btu's or may need a couple of units that size.  

I am installing one in my nephew's rental home, mounting it on a TV cabinet, so  it will remain portable, and they can take it to another location when they move.  It will have the tubing connected to the outside unit and go out a sliding window.  The 12,000 Btu unit will provide "Some" heat to the living room, and adjacent rooms at about 12,000 Btu's per KW of power, so that the electric heaters that only put out 3,400 Btu's per KW will not need to run very much to keep the nearby rooms above 63F.  

So he is getting one unit, and it will provide about 50% of the heat needed in his 1,300 square foot home in Washington where the local temperature will go down to about 23F on a very cold night in the middle of winter, but will normally be in the 30 to 45F range during the day and night.  

Of course a 47F day in the fall, the heat pump can warm the whole house to above 66F by itself.  At 20F, the heat needs increase, as well as the discharge air temperature for the heat pump outdoor unit will also decrease, so it must work harder.   At that point, my guess is during the morning they might run the bedroom electric heater to get the temperature comfortable in that room for a few minutes each cold morning.  There overall heating cost should be about 50% to 40% of the amount they would need without the heat pump.

**Q: How warm can this unit heat a 300 square feet space in the winter when there is snow?**
A: Ignore the answer about heat pumps not working below 40 degrees. These units use inverter technology, which allows them to run well below freezing. This system can heat down to -5 degrees. I've used them in single digits and they heat fine. That being said, even though the original question was quite a while ago, for anybody else I would opt for the 12,000 btu unit.

**Q: What is an E1 code displayed?**
A: E-1code means shut down unit for 10 minutes or so should reset,if it doesn't restart you need a tec.

### ⭐⭐⭐⭐⭐ Very impressed
*by C***N on March 12, 2025*

Just had the system installed. Done by a professional, but at a low cost because it is quite easy. No special training needed. Right away, love it. It's in the living room/dining room area, so shut off central air most of the day, no need to AC upstairs bedrooms. It runs continuously, so no spikes of AC blast, followed by a warming period. Quiet inside and outside - so nice. Its small size means easy to place and not an eyesore. Has bluetooth. Also, it's 110 voltage plug-in, so much easier to install, without a permit. I've used the better known brands before with great results. So far, this system seems just as good. Only day 2, I'll do an update in a few months.
