This is a great, high-quality product that functions well. I thoroughly recommend the Senville for quality and performance. The install is a difficult level DIY and should only be attempted after proper research and with proper tools. Physically installing the units is easy. Wiring the units is not difficult but is time consuming, especially accounting for running a dedicated 20A electrical circuit. Line set installation is more involved. I chose to hang the inside unit before attaching the line set because of how I chose to run the refrigerant piping inside the room and then straight through the wall to the outside unit. I made my own wall pass-through sleeve from 3" pvc to give a little more working space. The included sleeve is very thin and flimsy. Line set flare nuts MUST be torqued to spec. I had one nut that failed and had to remove, replace with an included extra, and reflare the connection when I found the leak during the first pressure test. I shortened the refrigerant piping at the outside unit to fit with no looping of pipes. I used an eccentric flaring tool to remake the connection after shortening. Next step of pressure testing with nitrogen MUST NOT BE OMITTED. You will need a HVAC charging manifold, special fittings, a micron vacuum gauge, HVAC leak test soap, a compressed nitrogen tank and regulator, and a vacuum pump. A competent pro installer will do this--but many HVAC techs skip the pressure test step. I pressure tested and found the bad flare nut leak, repaired it, and pressure tested again to 300psi nitrogen. This forces most air and water out of the lines. I left the lines on pressure, applied leak test soap and left the set up for over 1 hour. There was absolutely no leakage according to the HVAC manifold gauge. After pressure testing, a vacuum test was performed using a micron vacuum gauge to make sure all nitrogen, air and water vapor was removed from the lines. You will need special fittings as mentioned, to insure that the lines remain isolated from the pump after evacuating. I vacuumed down to 220microns and let it sit for 30+ minutes. The gauge remained well below 300 microns. (the standard is to remain below 500 microns). This step double checks for leakage and confirms removal of all gasses and water before releasing the factory charge into the system. Next, isolate the gauge from the system using the special fittings, and release the refrigerant charge from the compressor into the system. After a final check for leaks after removing all gauges and fittings, the system was ready to power up and test run. Note: the flare nuts are crudely shaped on the outside (seem to be cast, rather than machined) so normal open ended wrenches do not fit them well. You will have to use adjustable wrenches to adjust them when installing. Using a torque wrench on those flare nuts is difficult because of the non-standard finish and sizing. A $175 adjustable wrench head HVAC torque wrench (made by Yellow Jacket) would really assist here, but I had a standard torque wrench with crow's foot wrench adapters. I made it work... but that's not an easy way to do it. I doubt many techs carry the special torque wrench and will just do the flare nuts by feel based on experience. The test run of the unit revealed no leaks, so I wrapped up the line set at the connection points and finished the install. I used a line set cover flashing to protect the lines where they emerged from the outside wall. Zip ties where needed to secure the wrapping tape. Big HVAC type zip ties screwed to the wall to mount the indoor line set in permanent fashion. double checked the drain line was working properly without restriction by pouring water in the top of the inside unit and verifying full drainage. I left the primary drain line joint uncovered inside so I could have access if there was ever a blockage. The unit heats wonderfully, cooling is great, too, but I will have to confirm how that works on a really hot day this summer. You will have to run the cooling check on manual cool override if temperature is below 62º outside (it was cool here on the test day). The air output on cooling feels ice-cold. Spend the time and money to install it correctly and the Senville will serve you well, I think. If you are not comfortable doing it DIY, then hire a good installer. You will not have factory warranty without a professional installer according to Senville. I chose DIY anyway after researching the process and finding than some installers skip the pressure test. (Senville in fact does not insist on a pressure test in the install manual.) 22 months in, I could not be more pleased. Keeps my garage/workshop comfortable year round (outside temps ranging from 7° to 97°) and has very little impact on my power bill. Just keep the filters and fins clean for best efficiency. So far, I have not needed to clean the blower wheel. No problems with the condensate drain at all.

We were looking for something to cool our add on to house and this works great. I love how it’s heat and air! We haven’t had any problems with leaks. The power is very good and it’s quiet. It makes our add on very comfortable now! It’s holding up very well.

I am a recently retired HVAC tech. I can only say...WOW! lets start with the item packaging. Everything was well packed and arrived undamaged. Everything seems well made and well thought out. Even the line set had perfect flares. The only thing I can say is a negative is the power/signal cable between the condenser and the air handler is about two feet shorter than the line set. The line set is easy to bend and is seamless, so if you had to re-flare it, it shouldn't split at the seam. I used a little Nylock on the flares and upon evacuation system held a vacuum with no measurable loss of vacuum in 24 hours. Once the system was pressurized, no leaks noted via leak tester or old fashioned soap bubbles. System passed all tests on startup. Even the amazon alexa setup was easy. Note that this is installed in an unconditioned space. I tested it the other morning, Outside temp was 33F. The indoor air handler was blowing 128F air!!!!! I am impressed!!! Once upon a time, you were lucky to get 90 degree air out of a heat pump. I am heating/cooling only 240 sq feet ( uninsulated) with 18000 BTU's and this thing brings the temp up quite rapidly. The fact that I can tell the system to switch on and set the temp via Alexa is awesome. Also note that there appears to be parts available as well if they are ever needed. I did have a minor issue with figuring where to plug the wifi dongle so I reached out to customer service. They were quick to respond and quite helpful, so A+ there as well. I could have spent a little less, but I felt this was all around a better product.

Very quiet, and it cools down a room really well. I love having a remote, it just makes it real easy to use. I insulated my shed and had this installed. It was simple for the HVAC guys to install, appears to be good quality, and it doesn't appear to be adding much to my electric bill. I really like that the manufacturer provides a 5 year warranty if installed by a professional.

Installation (hang on wall and put pipes and wires out through hole and cover, set up on stand, etc) not difficult if handy. Got electrician to wire and Hvac guy to vacuum pump. Working well so far. Nicely quiet.

I installed this in my 44 ft rv and it was easy. This thing burns half the power my electric fireplace did and is quiet. It puts out nice heat and it dehumidifies the trailer very quick. I have put away the 2 dehumidifiers and the fireplace. My furnace runs less than half as much and no hot -cold temp swings. Just nice even temps. (Alexa will only turn it on or off, you can't change temp or mode.)

Received packages ahead of schedule in good shape. Brought out to my Rv and installed the head, electrical and lineset. Used my 20 amp washer circuit as power , ran some 12/2 into a disconnect box, put 150lbs nitrogen on circuit to pressure test it for 30 minutes, sucked air out with vacuum pump, released refrigerant, am testing as I write this.Unit works extremely well, gonna be a bonus with the heat pump function. I’ve been doing HVAC for 35 years and this unit outperforms some of the Lennox products I’ve installed and at at a fraction of the cost, will submit another review on the heating side. At least now I’m prepared for the Okanagan summers in an Rv.New update as of December 12/24, been running unit on heat mode now for 2 months with outside temperatures of-2c, unit pumps out 74 Fahrenheit all day long, goes into defrost every 30 minutes or so. Very pleased with unit, will have to see if they sell a 2 zone unit in 110volt

If you have some technical skills, the install is a breeze. Some great install videos on youtube. The mini split works well both as an airconditioner and a heat pump.

This HVAC unit was received and installed about a month ago. It is a very quiet and efficient unit. It is also easy to operate. I am very satisfied with this purchase.
