24000 BTU - Very happy - Experienced DIY'ers or Professional HVAC installation recommended
Bought this for my 1350 Square Foot finished basement. This unit provides AC, Heat and dehumidifying which is exactly what I needed. After a month or more of use, it admirably provides all of that and does so efficiently and quietly! Installation. This is the only Mini-split I have ever installed so there is always a learning curve. I am very familiar with HVAC and I have many of the tools already since I worked on automotive HVAC from time to time and I consider myself to be a pretty knowledgeable on the subject. You will need a set of gauges, evacuation/vacuum pump, you may need a flaring tool, a hole saw 3.5"....and if you were like me, I was going through brick and concrete block so be ready to spend some money on that since masonry bits that size with a drill to go with it are not cheap! If you are going through siding and wood it is a much easier proposition. I would also recommend getting a cover kit for all the piping so you can make it look neat and protect all of that from elements. Power...you will need 220V at 25Amp, with a disconnect on the outside next to the unit and it will need to be accessible for future service and it is hardwired from your box to the outside AC unit. In my case, the air-handler that in on the inside of the home, is powered from a cable that comes from the outside unit so no additional receptacles were required. With this purchase it came with 16' of copper hose (two), a control power cable and drain hose. Depending on your application you may want to shorten the hoses or you may need to add to it. In either case this will require a flaring tool...fittings do come with the system if you need to this. If you need to extend the tubing to over 25' you will also need to add "Freon" so unless you are a licensed A/C contractor, well you may need one for that. 16' was actually perfect for my application. I have a family member who is an electrician, so I had that part installed and permitted to keep everything up and up especially when/if I sell the house. He also helped me install the Mini-Split. It took us about 4 hours to install and we had no issues with the installation and because he is an electrician he had the 3.5" masonry drill bit and 1/2 inch rotary drill that we needed. I can say it was pretty straight forward and there are plenty of YouTube videos where people do step by step installation. The instructions are helpful but confusing at times, so this is where experience is helpful to read in between the lines...since the instructions are for multiple units they sell and they are not all the same!!!! Now that I have done one I feel pretty confident to do another. I would also buy this product again with out hesitation. My only recommendation is if you have to buy the tools to be able to do the job, I would recommend just calling an AC professional and have them install. The cost of the necessary tools you may need may not be worth the investment unless you plan to do more of these in the future. If you do not even have a vacuum pump, gauges, flare tool etc, then you likely do not have experience either, and I would recommend you seek professional installation. Note: I saw on some videos people not vacuuming out the lines and just putting the systems together and releasing the preloaded Freon into the system (avoiding the need to purchase or rent a evacuation/vac pump). This is a bad idea since it introduces air and moisture into the system that will degrade its performance, shorten life span of the components and voids the warranty, plus you need that step to check for leaks. Freon is not cheap! Take a gut check on this. If you are handy and confident with your skills, go for it! If you are not sure, maybe seek someone out who has done it to help, or just call an competent HVAC tech to come out and do it for you.

Excellent Performance & Great Support
Excellent Performance & Great Support I installed this Senville LETO mini split in my Pennsylvania basement, and it has performed amazingly well—even through our cold PA winters. Once installed by a professional, the whole setup was a breeze and has been running flawlessly. I own a few other mini splits, and this one definitely holds its own. The heating and cooling power are strong, quiet, and consistent. The only small issue I ran into was with the Wi-Fi kit not working at first, but I contacted Senville and their customer service was great—they sent me a replacement for free until everything connected properly. Now it works perfectly with the NetHomePlus app along with the rest of my units. Overall, extremely happy with this mini split. Great value, great performance, and great support. Highly recommended.

Nice little unit.
Got it installed, directions aren’t the best but figured it out. The rest was easy for me to install. Worked fine heated and cooled really well. Have it I. The more opened end of my house living room kitchen area. Both inside and out side fans are. Really quite was surprised. We will see after a year of use.

So far...so good!
First time installing one of these. Put it in my new office which is separate from the house HVAC on as part of my garage. Inside Install: The inside unit was a breeze to install. I had space inside the wall so my lines are run in-between the 2x6 walls instead of the outside. the white rap that goes around the lines is like tennis racquet grip, only sticky on the ends so I didn't use it. I used foil based tape to wrap everything. Outside Install: again, pretty easy. I used sakrete to make a 3x4 pad and then after it was dry used a hammer drill to set anchors to bolt the unit down. I got a exterior dryer vent at lowes for where my lines come out of the house(my lines are inside the wall) and foil tape wrapped everything. Charging: You do need a vacuum pump, gauges and mini-split gauge adapters. If you have that...this is a simple job. Luckily my dad had all the stuff I needed! Vacuum to -25lbs took about 5 minutes. It held -25lbs for an hour so I knew there were no leaks. removed the gauges and release the freon. instant cold air and VERY quiet. what I learned after the fact: -The wireless module is an extra purchase....not needed for me but would have been nice. definitely not work 100 bucks. -There is no fan eco mode which means the inside fan runs non-stop even in "auto" mode. You can't hear it at all and its a non-issue. The compressor only kicks on when it needs to cool or heat. -Nail Polish Remover will remove all the senville and Leto logo's from the unit so that is is just white and blends into the wall. -I have seen zero change in my electric bill so far and Texas gets HOT. -I thought A/C was hard, turns out...its not rocket science, just requires a couple specific tools. The quote from my local guy for a similar system was 3k(and this was NOT a mitsu)...this was much much cheaper even if it were to fail at a faster ratio than what the A/C guy proposed. -I quit fiddling with the temp once I got it where I like it and haven't touched it since. In my small 275sq ft office that is foam insulated with 5/8 drywall I have to wear a jacket with the thermostat at 76 degrees with the 9k unit. any colder than that its hard to be in here. Insulation plays a huge role...but this is a really efficient unit. Summary: easy, cheap, efficient, no brainer. Im sure there are much nicer systems out there...but this unit is doing its thing and that's all I care about. Update: The unit is still awesome 6 months later. Quiet and insanely efficient. Update 2: The WIFI modules are UNIVERSAL!!! Order this Wifi module for $29 -> PIONEER Wi-Fi Remote Programming and Access Module for Pioneer WYS Series Heat Pump Systems the Senville Leto Wifi module costs between 79-99 depending on the sales. After doing some research turns out all of these units are "midea" based units and here are many of the units that fall into that category (Hualing, Senville, Klimaire, AirCon, Century, Pridiom, Thermocore, Comfee, Alpine Home Air, Artel, Beko, Electrolux, Galactic, Idea, Inventor, Kaisai, Mitsui, Mr. Cool, Neoclima, Olimpia Splendid, Pioneer, QLIMA, Royal Clima, Qzen, Toshiba, Carrier, Goodman, Friedrich, Samsung, Kenmore, Trane, Lennox, LG, Electra). Installation was easy: 1. Downloaded the NetHomePlus app, created an account and had it ready to go. 2. Turned Breaker off to the Senville Leto Split. 3. Plug in the USB module into the lid of the senville (the lid opens up and it plugs right tin). 4. Turn break back on. 5. Open NetHomePlus, click add unit. (instructions online say you need to scan the included QR code. I did not, the app just found the unit and auto added the split, didn't have to do any of the "AP Mode" instructions) 6. the App configured the wifi, changed the units to Farenheight and I was done. Working perfectly. ----- Extra steps: I wanted to then add it into my HomeKit setup that im using with Hoobs(home bridge). In Hoobs(home bridge) install the Midea Air Bridge (1.4.1 at the time of this review) (https://github.com/hillaliy/homebridge-midea-air). 7. Add username and pass from NetHomePlus app into the config. The MideaAirBridge auto found the unit and didn't even have to configure it. 8. Add the accessory in Homekit and it will put a device in the room from the split. Still loving the Senville and now that I have it setup on wifi with HomeKit im very happy.

I enjoyed installing this and it's worked out very well. We're using it to keep the garage cool in the summer and warm in the winter. It's doing a very good job. Installation was straightforward. Proper evacuation and leak-free joints are essential. The Alexa app is good enough but the WiFi one would have been better.

Hi, I am a advance DIY and just finished the install. Did everything by the book. Unit starts (the fan of the indoor unit) but after a few minutes, shows error E1. I’ve recheck everything. Not sure how Senville (or Amazon will handle this)? Edit, Unit is now working perfectly. It was not an easy problem to troubleshoot. It ended-up being the terminal block in the indoor unit having a defective contact when tightening the screw. A new terminal block will be sent next week. If you have issues, call support, they are there to help you. They even proposed to compensate me for the trouble I had with the system! I now added the unit in Alexa and can control the unit. Very happy with my purchase.

This is a great air conditioner easy to install and very efficient and quiet. You can use Alexa with the unit as well which is very nice! Delivery was very quick and faster than expected! All around happy with our purchase

I'm impressed by this units performance. Installed in a 24 x 30 well insulated garage in April. Cooling performance in summer was great. Was expecting this but looked forward to seeing how it performed in heating mode. I'm in Winnipeg, -25c this morning and it was still pushing heat. Crazy. My 8kw hydronic in-floor boiler has yet to fire and its December 7th. Our November power bill was 40% less this year than last.

We installed the 36,000 BTU single zone mini-spit unit in our 1,700 square foot store, and it handles it like a charm. We can easily make it too cold in there! This unit is very quiet, both inside and out, and was a very straight forward DIY install; no proffessional needed You do need a vacuum pump to pull a vacuum on the lines and evaporator, and if you cut the lines, they do need to be re-flared; I chose to just leave them with a little extra.
