Senville LETO Series Mini Split Air Conditioner Heat Pump, 18000 BTU 208/230V, Inverter, Works with Alexa, SEER2 19, 1.5 Ton, White

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 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.

Been very happy with this product , I bought and installed myself , 2024 . I’m a heating A/C technician. I was looking for “name brand “quality, and reliability and not name brand price. Through a lot of research found out that Senville is made by the Chinese company “ Midea Group”.. through more research I found out that they also make for major namebrand products such as Bosch Carrier Mr. cool pioneer.. which come with the name brand price . Long story short .. installed the Leto model and works wonderfully .. inverter technology makes it very cold in summer very hot in winter while drawing very little electricity .. I did have one hiccup.. lost power to my home and damaged a circuit board. Luckily Still under warranty, and found out , really already knew ! ! , that I should of protected the system with surge protection,as inverters are not very durable and could be damaged with power fluctuations into your home.. Here we are 2026 and love my senville mini split ! Highly recommended

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.

This is a review of the Senville 18K BTU LETO heat pump. I installed this unit myself, so I have no warranty to fall back on. That was a risk I was willing to take to save the installation fee, which is often $400 or more. And some contractors will not install a unit they did not sell. But the installation went fine. I watched a couple of YouTube videos and bought a vacuum pump with gauges ($129) to make the job possible. I also bought a product that you smear on the connections to increase their reliability. The most time consuming part of installing the unit was mounting the indoor and outdoor units. As others have said, it would be very helpful if Senville supplied a template for mounting the indoor unit. Both the indoor and outdoor units are very quiet, attractively styled, and do the job they are made to do. I did have a couple of disappointments, however. First, the "swing" feature that spreads the air around works only up and down. I had thought the advertisement said the vent fins would swing side to side as well. They do not. There are fins that direct the airflow horizontally, and they can be manually moved to change the airflow direction, but they won't sweep side to side on their own. I read through the ads and the technical literature on Senville's website, and the operation of the sweep feature is not mentioned, as far as I can tell. Second, the remote controller does not support programming the unit for different times of day or days of the week. It's a fairly basic remote. The Alexa integration might enable one to program the unit, but I have found that you have to choose between controlling the unit with Alexa and controlling it with the remote. They don't play well together. The remote does not know what Alexa is doing to the unit and gets out of sync. Alexa seems to know what the remote has done, however. Anyway, it's confusing to use both. I need to use the remote because not everyone in the house is a fan of Alexa. So after playing with the Alexa integration for a while, I have decided to disable it. I am a sad nerd. Neither the lack of horizontal swing nor the Alexa integration problem are too big a deal to me, so I'm happy with my purchase, especially for the price. But I would be even happier if I had know about these two issues before I decided to buy the Senville unit. Update: The unit has been running for a couple of weeks now, flawlessly. The temperature in the room is very stable. I simply forget that it's there doing its job. I have discovered that the follow me feature has a serious limitation; the remote control must be within visual range of the wall unit. You cannot take the remote into another room and expect the heat pump to monitor the temperature in that room. If the wall unit does not get a message from the remote for 8 minutes or so, the follow me feature is effectively turned off and the wall unit temp. sensor takes over. I think the remote transmits the temperature it senses every 2 or 3 minutes. I still use the feature since my wall unit is mounted near the main entrance, which is slightly cooler than the middle of the room in the winter, but I cannot leave the remote in its wall holder since that kills the link between it and the wall unit because the IR beam is pointed at the ceiling.

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 have put in maybe 6 or 7 senville mini splits now and no problem with any of them after several years. This one is pretty quiet and puts out a nice amount of heat. Only issue I had was the wifi adapter it comes with only works with alexa and not the net home plus phone app, so I had to buy that separately but now it works fine remotely.

Update: still complete junk even with an auxiliary controller, but better since I can control it from my phone since I have to mess with it ten times a day! Still doesn’t stay anywhere near the temp, and seems to be getting worse even though no leaks detected anywhere. costs extra money in power which defeats the purpose of having it. Also have to be messing with it 24/7. Have not heard of a single positive review of any senville unit between landlords, clients, and other hvac people. It’s the cheapest for a reason. I plan to get another and use this in my basement or somewhere it’s only needed every once in a while. Just cannot believe how terrible this thing is for over a thousand dollars. I know it’s not top of the line, but come on, thermostat temp not even remotely close to room temp and the unit always wants to stay on low. All directions followed, we are well aware of how to install hvac units including splits and have done several others. All others have zero issues. No others are senville nor will they ever be. I wish I could do a chargeback or return it if it wasn’t already installed. The installation was straightforward, but the controls/settings are very wonky. We have installed a few before so it does take some know-how and equipment, but if you’re familiar with the installation process it’s not very difficult. FIL is a certified HVAC tech so that helps a lot. Started it up and it heats well. Noise is pretty minimal for both units except when indoor unit fan is on high, but still not that loud, which is similar to every other mini split we’ve installed. The only issue is that controlling it accurately really difficult because it always stops a few degrees before the temp set, and it seems to vary a lot. I’m not sure if the issue is with the thermostat reading a different temp than it actually is in the room, but even with it set to the “follow me” setting where it shows the current temp(which is accurate), it still doesn’t get close to the temp we set it at. We set it to 72, and the highest it will get is 68 before it stops heating. Set it to 76, it gets to 72, but then seems to wait until it’s close to 67-68 before cycling back on, so it gets kind of cool then warm again. This is a 24K btu unit in a roughly 400sq ft room with ambient temps around 55, so it really should not be difficult at all. It does seem to get up to temp when set on turbo, but one of the main reasons we got it was for energy saving, so running it on turbo all the time is not ideal. For now we just set it above the temp we want, and that seems to mostly get it to where we want it. Still, I’m not sure why this is the case. The other units we have installed from klimaire were more annoying to install, but they worked in a straightforward way and reached the set temp without any issue. There doesn’t seem to be any issue with the unit itself, just the software or controller. For now we are looking into getting a universal controller, but that’s another 100$+ and then we also have to set it up and hope there are no issues with that, and that’s assuming it will help the situation. I have read that many of these mini split thermostats are inaccurate, so perhaps that is our issue, but the remote thermostat is accurate when we put it on “follow me”, so I’m not sure why it still shuts off before reaching the set temp with it set to the “follow me” setting. Overall we are sort of “meh” about it with all things considered. The price was pretty good for the output so we weren’t expecting it to be flawless, but after getting the necessary parts it didn’t come with like mounting equipment, and now a universal thermostat, it’s not much less than the brands that do work pretty flawlessly like we have installed before. We ended up spending the same amount roughly, and now we still have to go through the setting up a separate thermostat for it, and we’re still not sure that will work. I will say that the installation was less of a hassle than others because it has more options for how to route the piping out of the indoor unit, but otherwise it has not lived up to expectations. The installation being slightly less of a hassle is nice, but the main concern is that it works properly and consistently, which it seems to have an issue with. It seems to mainly be an issue of software or with the thermostat as it puts out heat, cold, and does very well with dehumidifying.. but it just doesn’t get to the set temp, and it drops too far before coming back on. Overall, we will not be buying another unit from this company. It was affordable and relatively easy to install, but we really dislike the controller and how it works. Others we have installed get to the set temp and then stay pretty close, and we don’t have to mess with the settings to get them to do so. The only other positive to it is that it does turn the fan on low or off whenever it does get close to the set temp, which is not something that many of them do, and that does help with noise if you’re trying to watch tv or etc. overall not especially unhappy with it so far, but it’s a lot of money to spend on something to think “it’s okay” when I could’ve spent only slightly more by the time it’s all done to have one that I know works flawlessly, and that I don’t have to mess with the settings on constantly. Now I have to go buy another thing that’s not cheap and go through the hassle of setting it up in hopes that it makes the split work normally like every other one we’ve ever installed. Wish I would’ve spent a little more on one that doesn’t have such wonky controls and thermostat, or whatever it is that’s causing it to always be a few degrees below the set temp.
