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.

Great product
I’m very pleased. Product is very well assembled and sealed. Pressurized great. Small details are evident and made for a smooth install. At max heat (86deg) it was putting out 115 deg 👍. Fan is super quiet, and features are great for this price. Paid about $1k to have professionally installed. Suggest doing that so testing and hose cleaning can be done for best performance.

Good basic unit
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.

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.
