SenvilleLETO Series Mini Split Air Conditioner Heat Pump, 24000 BTU 208/230V, Inverter, Works with Alexa, SEER2 18, 2 Ton, White

I started looking up different brands for a mini split unit to replace my decades old unit in a second story condo. My contractor recommended a couple brands as well, and Senville was one of them. I ended up choosing Senville primarily because of the WiFi connectivity even though there were some issues in the Amazon reviews about that. Secondarily it advertised a better than average SEER efficiency rating. The reason I valued the connectivity over efficiency is that the room I was installing this unit in is very small and the ability to control the AC and Heating away from home would allow me to minimize the time the unit was running anyway.Senville arranges shipping separately from Amazon. It was a bit strange being contacted by a third party to arrange the shipping, but they were able to supply information from the order upfront at the beginning of the call and didn't ask for personal identifying information besides contact info and address to ship to. The unit actually shipped within a week, which was shorter than the original shipping time estimate.I had my contractor install the unit and thankfully the basic 16ft lineset that came with the unit was sufficient. I wouldn't have minded upgrading to the 25ft lineset if needed, and it was advertised clearly on the Senville website anyway. The remote to the unit worked easily. The unit blows air smoothly to the other side of the room (almost 20ft away!), which I wasn't expecting. It's also quiet, around the same volume as my ceiling fan, which is quiet even on the high setting. I don't intend to run the unit much, or during hours when I would notice the volume much, but it still feels good that it meets this benchmark. Haven't run it long enough to confirm the SEER rating of 21, but given the quality of operation otherwise I have a lot of confidence that it will meet that rating.The final hiccup occurred when I tried to get the unit connected to the Senville app. After following the instructions a few times I called the customer service line. I found out that the USB dongle that comes with the unit to give it internet connectivity actually comes in two varieties: one for connecting specifically to the Alexa app only, and a different one for connecting to the Senville app on iOS or Android. Unfortunately the listing on Amazon for this mini split was ambiguous (to me, anyway) about there being different USB dongles and my order came with the wrong one.When I explained the situation to the customer service representative he offered to send me the correct dongle for free. The whole process contacting customer service probably only took 15 mins, from looking up the contact info on Amazon all the way through getting an email confirmation about the new dongle being shipped.This experience gets five stars from me for the overall high quality operation of the unit, the unit meeting my design needs, and Senville's easy customer service handling a small issue quickly and painlessly.

During the install of the inside unit, I noticed that one of the two cables was unattached. I contacted Senville support, and they said that unplugged gray cable marked 'ABCDE' is for an optional 5 pin thermostat. Also, if you are looking for the Alexa USB port, the white box with a screw in it needs to be opened to be able to insert the usb and setup Alexa for your unit. I think there is room for improvement in the user manual. It covers the basics well, but it is confusing for one manual to cover all different units and the installation steps could use more embellishment. Also, don't forget the adapter for the currently used refrigerant. For my unit and A/C gauge, I ordered "Senville R410A Adapter 5/16" SAE Female to 1/4" SAE Male Vacuum Service Port for Mini Split Air Conditioners" https://www.amazon.com/dp/B0798W1Z1V?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1.

Functionality:I bought this from Amazon and installed myself. I thought it was quite a project to take on. I have a 80 year old brick house 30X30 with full basement and all I had was window units. It took me 2+weeks to properly install. But this unit completely cools my house even the basement and takes all the humidity out of the basement. Senville I could not be anymore happier on how it works. It was a challenge but well worth while. The hardest thing on the project was going through concrete block and brick with a core saw for the copper line and electrical wire and drain tube. The only thing that happened was I misread. I saw the coolant could handle 25’ which I assumed it had 25 ‘ of line but only had 16’ so I had to purchase a 25’ line which I needed 19’ but that was my bad. Also I did purchase a 25’ line just in case I need to replace if the communication error pops up again. Because watching u-tube videos the electrical line should not be spliced.
