ROVSUN 12000 BTU Wifi Enabled Mini Split Air Conditioner & Heater with Inverter, 21 SEER2 Energy Saving 115V Ductless Split AC Unit with Pre-Charged Condenser, Heat Pump & Installation Kit

I cannot say enough good things about this mini split. Easy install, great quality, very good price. It has all the features of the higher priced units and appears to skimp on nothing. I am truly impressed and this may be one of the best purchases I have made in quite a while. I am ordering another bigger unit for another part of my house. This is a big thumbs up in all regards except one....the instructions. And not all the instructions, when it comes to charging the unit for startup. They jump from hooking the unit to power and connecting the copper lines to operation and miss the step about testing for leaks. If you go to YouTube there are a bunch of HVAC people who make it look WAY harder than it is so you will call them up and pay $1000 for them to do this very easy thing. Go deep on YouTube and find a video of a homeowner or non-professional doing the vacuum testing and it will get you to the finish line. You will need to but the manifold guage (or borrow one from a friend) and pump to do the last step but at worst you are looking at $100 to buy the kit on Amazon. I bought one that allows me to charge the AC system on cars too so I will make use of it again down the road. Overall this is a terrific unit, heating and cooling like a champ, many features, quiet and reliable.****UPDATE*****It's been two years since buying and installing this mini split and it works as well as the day I got it up and running. It keeps chugging along in hot or cold weather keeping folks comfy. I bought another ROVSUN unit about a year ago for the garage. The newer model is 21 Seer and I got the 12.000 btu model. The same story with that one; easy install, well made product, great price.

I purchased this unit to replace a window AC/Heater. . The window A/C was loud and expensive to operate.I was concerned that the ROVSUN 9000 btu 115 volt might be too large for the area. But it does an excellent job of cooling and heating the space. I purchased it during the summer of 2024 and now we are into winter and it is doing a great job of keeping the specific area in perfect temperature balance. The system is virtually silent. I cannot tell that it is running. The inside condenser/blower system is stylish, but looks a little large on the wall, not so much that it is a problem. I have detected no problems in moisture, or condensation when it is running with the outside temperature at 90+ degrees and 70% humidity. We live in Florida and the summers can be brutal.It also has reduced the cost of electricity by almost half for this area.I would buy another one in a heartbeat.I hired a professional installer to put in the unit. I was with him the entire time and the installation looked straightforward and easy. The installation requires some specialty equipment. A vacuum pump, gauges, etc. Items that are not normally found in a home tool kit. But if I had had the specific items and the correct training, while I pride myself on being very handy at building and installing things, I think using a professional to install this unit was the right choice.My hope is that this unit will last many years and continue to doing a great job.

Installed three units now and have been really impressed with Rovsun. Quiet, and great heating specs. They need to advertise their heating specs better, very impressive especially at this price point.

AFTER 1 FULL YEAR OF USE:Here is a breakdown on ROI. For 12 months prior to installation there was a total usage of 13,229 KWH and 10,142 KWH for the 12 months after install. It was a slightly warmer summer (+2.2° F) and slightly colder winter (-2.5° F) in the year before install on avg. so that can account for a small amount of the difference but still ≈3000 KWH less usage for a total savings of almost $400 at the avg. rate of 13¢/KWH. I spent a total of $680 counting extra installation supplies, so that yields a true ROI of just under 21 months! Obviously that calculation projects no additional costs for repair or maintenance over the next 9 months, but since there were none over the first 12 months and most failures over the first 5 years occur in the first few months of use, this ROI figure is probably accurate. The use of a window unit and electric resistance heat previously were clearly a worst case scenario, so your results may not yield quite this good a result. This does give a great analysis of how quickly a change like this of one piece of equipment can make.The entire unit is still working properly. I was afraid I might lose an inverter PCB as this was an inexpensive unit & cheap Chinese boards are not that reliable. Other than my notes about needing better installation supplies, my previous commentary still applies & considering the price, an extra $100 for the best installation is still a good deal. For DIYs who don't want to spend money on tools, the manifold & vacuum pump are available as free loaners from most auto parts stores. As for the connectivity problems on the phone app, I think if people ensure they have locked in 2.4 ghz for their wireless connection they should be OK. If you don't have dedicated 2.4 or 2.4/5 configurability it will NOT work. If any part of this system ever gives out I will update. As for the paradise plans, I am still stuck in the madness unfortunately as things get even crazier 😔.UPDATE AFTER 4 MONTHS: Posted complete usage graph of summer for entire facility. No problems with unit so far.ENERGY USE UPDATE:(See attached usage bar chart)After several days of use with identical outdoor temps and heat load on the conditioned space, an avg. 12 KWH per day reduction of electrical usage was achieved. This was maintaining 75° in the space with the mini where the 1/2 ton window unit could only achieve a range through the day of 78° through 92° with constant 24/7 compressor operation, never making it down to 75° and using twice the KWH with half the btus. Even though the window unit only had half the SEER rating, this is pretty impressive for the mini. Obviously the savings would be less in spring and fall, with winter savings totally unknown. That will be updated when the data is in. My estimate is an ROI of less than 24 months. If this mini just has longevity, it will be worth it for sure. Original review below.Opinions after 1 week.First this was a test unit for me. I have installed only Mitsubishi units in the past and look upon them favorably, but they are quite a bit more expensive, especially the 30+ seer models, as you might expect. The test setup was a good one for determining how well the unit would perform in a challenging cooling environment. The indoor unit was hung in an uninsulated upstairs room (18x15) in S. TX this summer (2023) where the outside high temps have been hitting 105°+ regularly and hit 116° to 118° on several days with crippling humidity and extreme drought conditions. When I first started the unit the indoor space ambient was 108° and it was brought down to a 72° set point in 51 minutes, even with a very large amount of furniture and porous materials with a high latent heat load. While the space is considerably smaller than a 1 ton unit could normally cool, the heat load is massive for its size, so I still consider this impressive as the 1/2 ton window unit in use before could not keep the late afternoon temps below 90°. I will list the initial pros and cons below with the caveat that this is after only 1 week and for cooling (no heat test yet obviously) only.Pros:-Came quickly, well packed, no damage, both boxes delivered at the same time.-Units could be easily lifted by your average weak male and probably any average female as well.-Units were VERY quiet inside and out. I didn't think the outdoor unit was even running until I felt the very warm air gently blowing.-My Android app (Smartlife) installed and worked perfectly, though others have a much different experience, as you can see from all the 1 star reviews. I did setup a dedicated strong signal Wi-Fi router 6 feet from the unit locked on 2.4 ghz, which you MUST use as it will NOT support 5, so that may explain my success..-The ability to configure the unit is about as good as you will find on most higher priced minis. You have exact control of directional air flow and strength. Even on turbo the fan was so quiet it could not possibly disturb anyone. You also have the usual options such as eco, dehumidify, timer, sleep, and a few other probably less functional options such as anti mildew and auto clean.-If you don't have the Wi-Fi option (really recommend this for anyone with net access) then the remote will do the job. It has a nice LCD backlit display.-I got decent support by message with a 24 to 48 hr. response time. The support phone number for the company on their website is not even for this company which is usually the sign of a scam, but I knew this before ordering and figured Amazon would at least guarantee performance. I think they just don't want to be called but make it look like they do 🥺.Cons:-The installation supplies included are a far cry from what you get with a Mitsubishi. The lineset insulation is a bit of a joke IMHO, but I spent $70 extra to enclose everything in 5/8" wall K-flex tubing and Armaflex tape. The drainage hose is what you get on all cheap minis (though this one was strangely several feet short of the lineset length) so I substituted my own insulated hose ($18) and ran it separately from the K-flexed lineset and wiring bundle. No concrete or other type anchors are included for the outside unit ($4) and DON'T use the little plastic anchored screws for the indoor. I used 3" Senco screws directly into 2x4s screwed into the wall studs. You don't want one of these coming down on you, so don't trust the wallboard to hold it, even with metal mollys or toggles.-The liquid line coming from the indoor unit is 6" longer than the suction line. While the liquid line service valve on the outdoor unit is a couple of inches lower than the suction, you will still have extra and have to cut and re-flare the liquid line unless you have some extra room to add a curve. See my install tips below on this.-Although they swore the refrigerant was clearly listed on the outside unit plate (410a in this case) mine only listed it on the inside, which is unusual.Install tips:Obviously you will need a good vacuum pump, 5/16" to 1/4" adapter, and a manifold set. Sometimes newbies (and even pros) will incorrectly torque a flare connection. If you need to cut your lineset to exact length (highly recommended) then you will also need a good tubing cutter and high quality flare tool. Most people have some of these already so get a firm cost for a pro install versus new tool cost. I recommend you get 2 (or 4) pro-fit connectors for at least the 1/4" connections if you cut lines since they are foolproof and 1/4" flares are the most problematic for newbies. For $20 more get 2 for the suction line as well and forget flaring altogether, although if your needed lineset length is right at 16' forget that and carefully torque them down and make sure your vacuum holds before opening the valves. Do NOT coil up excess lineset to avoid cutting as you can create an oil sink/trap that could ruin your compressor. You need a dedicated 15 amp circuit for the 9k & 12k units, and I recommend you also add a cheap weatherproof non-fused disconnect ($10-$15) at the outdoor unit. If you stick to just what came with the unit for supplies, I think you are being penny wise and pound foolish. For an extra ≈ $100 you can have a first class install.Obviously the most important thing to consider is how long the unit will perform and the total cost over time, considering electrical use and maintenance plus the initial cost for actual ROI. Only time will tell, but I will add a detailed update after 1 year. I hope no updates beyond that are possible since I plan to be relaxing at my own remote paradise that needs no heating or cooling and does not suffer from the current madness infecting the country 😊.
