Senville LETO Mini Split Air Conditioner, Heat Pump, White, 18000 BTU

This is my 8th Senville mini split, I converted my home to Senville mini splits after my 20+ year old R-22 heat pumps died over the winter. I have contacted Senville customer service on three occasions, the first time I had questions related to the power options and asked my question through their website. I received a response in less than 24 hours, my questions were thoroughly answered and numerous links to related articles came attached to the response. Very helpful. Second occasion was during a installation and I called ther customer service, I was directed to the appropriate person within a few minutes and I had my issue resolved within a 10 to 15 munute phone call - again very helpful. The third time was email through Amazon - my 18000 btu unit arrived damaged by the carrier. The issue was resolved with two very brief emails and I had a replacement unit on my porch on the second day after I reported the damage. This company is very responsive to customers. The products I have installed - 2 - 18000 btu units and -6- 9000 btu units have all been installed without issue. I shortened -7- of the linesets and lengthened one lineset. No issues. The outside units are robust and run nearly silent, the inside units are practically silent and in heat or AC perform flawlessly. We have a 9000 btu unit installed in our livingroom within 6 feet of the TV - no issues - silent. Based on my experience, I highly recommend this company and their product.

Third one I have bought. Love it! Quiet, cools and heats immediately, Set up is easy, remote is handy. Aesthetically pleasing. Good quality, reasonably priced.

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.

I hated installing and uninstalling the window unit my family used to cool our home. I couldn't afford to have someone install a mini split for me so I watched some videos to see if it was something I could do myself. There are a lot of videos explaining how to install a mini split; some better than others. I recommend Doubelwide6's video on YouTube to install this unit. If you're a competent DYI handyperson you can do this. You will need to buy some specialty tools to do it correctly. I installed it last year over two days. (I had help from my daughter who wanted to install it with me so I worked slower than normal as I helped her to learn.) The first thing I noticed once I had it running is what I didn't notice; the noise that would drown my TV out when we were using the window unit. We live in a 1,040 SF (first floor) ranch style house and the 18,000 BTU keeps the whole house comfortable. As a bonus, the mini split can supplement our heat in the winter to take the chill out of the portion of the house I installed it in. I had no problems with the mini split, until the first hot day of this year hit. We turned the mini split on and after a few minutes we received an E1 code, which is the code given if the outside compressor and the indoor evaporator aren't talking to each other. I tried to research the issue but still had questions. I emailed customer service with some of the information I gathered. Based upon what I emailed I was told I needed a new outside control board. I expected to be charged for the board but with little more than proof I bought the unit within the previous year I was sent one for free. No proof that I had a professional install the unit. The mini split worked for a couple days after I installed the new board and suddenly threw another E1 code. I emailed the customer service representative and he sent me a new indoor control board. When that didn't work he called me and walked me through a few more tests. He ended up pushing my case up to his supervisor. His supervisor was perplexed that both boards didn't solve the issue so he sent me a box of parts to try, including a new communication cable, a motor, and two new boards in case one of the boards they sent previously was bad for some reason. The problem turned out being the longer communication cable I bought from another vendor prior to installing the mini split since the cable that came with unit was shorter than I needed. I had to install the outdoor compressor further from the evaporator than the included cable allowed. The longer cable was copper clad aluminum and began rotting from the inside out. After I replaced the cable with a copper cable the mini split started working perfectly. Whether you install it yourself or hire someone to do it for you you should be pleased with both the mini split and Senville's customer support.

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 bought this 18000 btu unit last summer and I absolutely love it. You can barely hear it - just air moving. Cools AND heats wonderfully and lowered the heck out of my electric bill. I'm in Southern CA and it was over 100 most of last summer. It's a winner, and I would definitely buy it again.

We chose this mini split system based on the positive reviews and what appeared to be a responsive customer service team. Unfortunately, our experience has been very disappointing. From the beginning, we had ongoing issues with the unit. At first, customer service was willing to take our calls and discuss the problems, but over time they became increasingly difficult to reach and eventually stopped responding altogether. We hired a licensed HVAC company to inspect the system, and they determined there appears to be an issue with the circuit board. The unit shuts off randomly and changes temperature settings on its own, making it unreliable and frustrating to use. We have made multiple attempts to work with customer service to resolve the problem, but our calls and requests have gone unanswered. We are very disappointed with both the product and the lack of support after the sale. Based on our experience, we cannot recommend this unit.

I installed this in a 100-year-old home with propane heat that usually burns 800 gallons throughout the winter to keep the house at 72F. When the price of propane shot up 50% in 2022 I decided to look into other options to save money. I installed this myself in an afternoon, but paid a HVAC technician $300 to pump the lines down and charge it. From November through March, my electricity bill increased an average of $150, but without having to pay for propane this unit paid for itself, the install, and the electricity it used in that time period. It starts to lose efficiency below freezing, and below 20F the temperature in the house dropped to the mid-60s. Our average daily temperatures rarely go below 20F, but if yours do you may want to get a higher efficiency unit rated for negative temperatures. In the summertime, I was surprised to discover this setup also saves $50-$100 each month while cooling the house better- The central air conditioner is newer (replaced in 2018) but the blower fan consumes a lot of power just to move the air around the house, around 800 watts. We decided to install a window unit on the second floor (Midea U, also excellent units, and likely the manufacturer of the compressor in this mini split) to help on days when it's above 80F outside which will pay for itself this summer in energy savings compared to the central air. I regret paying thousands of dollars replacing the central air system and furnace and wish I knew more about mini splits five years ago, with how well this unit works I doubt I will need to use the central system again. If you are heating with oil, propane, or electric baseboard heaters this system will pay for itself in the first year, and unless you have a high-efficiency heat pump with a variable speed blower it won't come close to this unit in terms of efficiency in the summertime either. I'm not even considering geothermal anymore as I don't think the potential energy savings would justify the installation cost in the long run even if I had to install a new mini split every 5 years.

Wanted to wait a bit and see how it would hold up, but I'm pretty impressed so far! Installed this 15 months ago, and has now been through two summers and one winter. Did the installation myself, but had an electrician come in to wire the 220v needed outside. Installation was pretty straightforward so long as you are a DIY kind of person. Keeps my 500 sq ft garage at a comfortable temperature year round. Heat pump does not do well below -10c but we knew this going in and have an alternate heat source for when the temperature falls below this. Definitely recommend!

c'est le paradis présentement avec des chaleurs accablantes a l'extérieur,je ne veux plus sortir de chez moi !! pour le chauffage on verra a l'hiver mais j'ai confiance !! tres silencieux et ultra efficace !!

Excellent heat pump I have run it for a couple years now without problem. I have 2 of these and they work well. I have 3 other brands of heat pumps all were serviced multiple times in their first 2 years. Great product. Great price.

Great product

Installation simple, efficace et silencieuse ! Durable le temps le dira ( le $ est très abordable) Super produit
