I bought this for a 20X40 workshop and it cools it off very well. It does excellent for a shop that’s not completely sealed and in temperatures over 100 degrees. I highly recommend this brand if you are looking for a nice mini split.

My shop gets so hot it's unbearable to work in for long. I installed this and what a difference. It is made so U can install it U'r self. It comes precharged. It's really quite simple. I never did any AC work before and I followed the instructions and had no trouble. This is something I should have done years ago. It's an extremely quiet unit. It's a heat pump so I'll get heat in the winter also. Can't be more satisfied.

I am an HVAC contractor and use these units on the regular. They are the best bang for your buck and by the better then most out there! The features and functionality of these units is perfect.

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 mini-split has been installed for about 3 weeks. I intended to use it in conjunction with my central Ac and forced air systems. My home is 1800sq ft and I ran only my whole house fan with the Cooling on the Mini split. This has effectively cooled my house. Temps were in mid 90s last week. Expectedly, the rooms farther away from the unit were warmer, but still comfortable.The indoor unit is whisper quiet as is the outdoor unit too. I’ve been checking my utility useage - with rate hikes in effect, I’m still saving money! I really am eager to see how this unit will operate during the winter. My projections are on point with this unit paying for itself within the 8-12 months with rising costs of energy.

Install was for an advanced DYI and the instructions are fair at best in some areas. Great YouTube videos for the unclear sections helped a lot. Unit is super quiet and blows awesome cold air! No HVAC company would come out and do a unit start up for less than $700 (unit was fully installed), so I did it myself and I guess that voids the 5 year warranty. I understand the position of HVAC companies not to undercut their own business, but $700 to Vac the system and open the Freon valves is crazy. If it quits it’s cheaper to just buy another one!

What a sweet setup. I don’t know how efficient it is but I’m 💯 it’s more efficient than my central air condition I have currently.Cons: the filter is something that I extremely dislike. I know I’ll have to go in there and clean the coils one day b/c of how porous the filter element is. Of the 15+ yrs that I’ve owned my central air condition system, I have not cleaned my coils once b/c I use quality filters.Bending the 90 degree bend a second time after it exits the wall - you better have a bender b/c that copper line will deform.When it reaches temperature - the fan still runs but at a very low speed - this annoys me. When the motor is running, it’s having a short life span. There is no way to turn it off completely once it reaches set temperature.———-I bought a 25ft line set, saving the 16ft line set later for another future unit (so I can sweat it together for a 32ft line set). I Cut 5ft off of the lines and soldered the connections on (included photo). I dislike flare connections. I have compression connections on the high side on my central air inside unit and it never leaked but they are not flared connections. They should look into that instead.A tip is once you drop the drain line outside, drop it straight down and let it drain then and there b/c it’s not a hard line and the ribs will trap water and debris and will clog - I promise.Don’t bother trying to level the hanging brackets - install as is. Once you try, the brackets will be too far from the wall and you won’t be able to anchor them correctly. I used 3/8”x4” tapcons.1/22/21I use this for heat - I know it’s not as efficient as in cool mode but I keep a close eye on the kWh usage with a meter to see how efficient it is. It’s very efficient. When I put this on full blast @ 80f, it will crank out 15amps for the first hour continuously. Levels off @ 3-4amps once temperature is nice and cozy. In about four hours, I’ve used about 1.7 kWh - that’s less than $0.75.I compare that to my 2.5 ton and I’m at $3$ for every four hours. It doesn’t sound like much but when you run it for 8-10hrs a day x 30 days, it adds up ($170 in just electric alone not adding tax, fuel and other bogus charges utility likes to charge).Extremely happy. Will update in the summer for cooling with conventional system is off the charts - like stupid expensive.———- 4/1/21Absolutely love this thing. I run this bad boy 12hrs a day @ 78 degrees and it cost around 0.65 cents (I have a 220v kWh meter).I will be building a filter shroud on top to use 12x36” filters. It will knock down efficiency so maybe 70-75 cents a day. The filter provided really and truly suck. It’s built for efficiency but at a cost of air filtration and quality of air. It doesnt filter anything serious to write home about.I still am disgusted about the lack function of not displaying the current temperature. I mean it’s so easy to add - why did they omit it Idk.The other thing is I’d like to mention is I’ve wired the mini split to run my central air fan so it circulates the air all around the house. Central air has a hepa filter and actually filters particles out from the air. This is crucial and very important. It turns off when the outside compressor turns off.I plan to buy another unit so that I’ll have two 30k btu units running. Don’t buy the 36k btu - efficientcy drops to 16 seer :(. This unit is 19 seer - 2 seer difference but does make a big difference. In energy consumption. If youre gonna run a unit that has a seer rating of 16 - might as well fix or replace your central air.I also bought a 12k btu unit and it’s seer rating is also 19 but I’m very excited to find out power consumption. That’s another review on to itself.More updates as time goes by.10/23/21. To date,I have used 2300kw and its a month short of a year. This is truly a money saver. Even if we multiply it by 13cents - that’s only $300 the whole damn year :) . My office consumes 40-50kw a day with a 4ton central unit. Let that sink in for ya (that’s 14,600kw a year / 365 days).12/24/22: I turned off my split just for fun to show to myself and to you how inefficient central air unit (cau) is. Starting in October to month of December but didn’t keep track of the $$$ b/c I was using cooling mode. It only increase about $70-75 with the cau.It stared to become cold in December so I decided to keep tabs on the electric use. We had temps dipped down to 30f here in Florida and I tell you what, the cau is so inefficient I was using 115-250kwh a day. My electric bill? $500 for the month of December 😂. Jokes on me but I did it all for science.To date, I have used a total of 5996.72kwh from December 2020 to October 2022. That’s $900 for two years of the mini split. That’s amazing!My next step is to buy mini split cau and replacing my old cau. I can buy a 20seer cau but that’s $20k vs a mini split cau for $5k. No brainer!1/18/23: I bought another split unit. Klimaire 30,000 btu 21 seer ($2000). I didn’t want to buy another sensiville b/c I wanted to try another brand. I will have two running. I’ll attached a meter on this one as well. I’ll keep you all posted.2/7/23. Completed install of the Klimaire 30k btu. Advertisement says 21 seer but the product I received was 18.6 seer. I contacted them and they sent a new seer rating - so the seer rating on the boxes are false? According to federal law, that was illegal 😂. Doesn’t matter to me anyways b/c…uhmmmm….. it’s the same unit as my Senville 30k btu. I used the Klimaire remote to control the Senville and vice versa. Units are dimensionally the same, guts are the same. Down to the location of the wall plate to even the wiring.I won’t get into too much details of the install but my installs are from personal experience and my views on what’s logically sound may differ from yours. What I have learned so far on other units I have installed is the most important:1. have them 30”away from the wall so you can actually clean the coils. I set mine on 4x4 + wall hanger kit. Came out great. If you install the unit perpendicular to the wall, you can have it however far you want b/c the coils will be easily accessible.2. The styrofoam insulation that comes with the pipes are absolute donkey crap - of course I already knew this coming in. I said to myself this crap will break down under the sun and weather. What wasn’t in the attic or encased in plastic shrouds were broken down by the elements.3. Drill the inside hole angled downwards the outside. This will allow the correct slope for the drain pipe. Sometimes even having the hole right at the edge of the inside evaporator casing still won’t allow enough drop for the drain pipe when your wall ls are 8-14” thick.4. Try to drop the drain pipe straight from the wall and down. Less the drain pipe runs horizontally, the better.5. If you need to go through concrete, buy the BINOTA Concrete Hole Saw Kit. Drills the most beautiful 3” holes any weekend warrior would approve of.6. If your runs are long, sweat the tubes together with silver - don’t connect them together via flair joints. I avoid flair joints as much as I can b/c they can easily leak.7. If your runs are short, cut the tubes to size. Make new flares and or reuse the ones you cut off. I promise you the styrofoams that are coiled up behind the machines b/c you chose not the shorten the tubes, will all deteriorate and you will have to come back and fix it - that requires cutting them off! It’s not fun.8. Clean your coils and or check them at the beginning of each spring. This will give you the same efficiency or very little loss of efficiency eat season.Now for some kWh testing. Before I get into the goods. I would like to put it out there that I hooked both units on one 40 amp breaker using #8 copper wire. I wanted to monitor kWh usage through one meter bc these two units will run simultaneously during the summer and winter while the central air fans circulate air throughout the entire house. 30amps max will be used.I turned on both units with one remote lol. ran the unit for an hour. From 78f to 72f. My meter was at 15.75 kWh. After an hr run it was at 17.14 kWh. That’s 1.4 kWh an hour running both machines FULL BLAST. WOW WOW WOW!What I found interesting is the the Senville ran at 2.4a while the Klimaire ran at 4.2a for a total of 6.6a. The Klimaire outside condensing unit fan was loud and fast while the Senville was quiet and slow.I’m really enjoying the new split unit and I simply can’t wait for summer to come and run more tests. Upload a few photos - hopefully amazon won’t delete my photos - idk why they keep on deleting them.Cheers.
