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

The Company and Customer Support: Rovsun's 12K BTU (1 ton) mini-split has been working phenomenally. I'd like to start by speaking about the 5-star customer service they provide with product support. For anyone hesitant about company support after the fact, they should not be worried here. When I needed support on one of my Rovsun units (I have installed several of their mini-splits), I simply emailed them using their form on the website, and they got back to me the next business day with an immediate solution to my issue. I have to explain that no matter what brand you go with, the potential for a mechanical defect is a possibility, so it really comes down to the company to be helpful in those situations, and Rovsun was not a letdown. This reason alone is enough to highly recommend this brand. However, there are pros to their mini-splits, too. The Mini-Split: I have worked professionally in the HVAC business since 2018, both as an installer and service technician, so I'd like to say I know a lot about HVAC equipment very well. This particular system is built just as well or better than many of the other units on the market today. There are no surprises when it comes to the installation, it puts together very well. The remote is very easy to use, and the buttons are large. The LCD light-up screen is intuitive to understand and is big enough to see all the numbers without struggling. It comes with a wall mount if you wish to hang it. The operation is very quiet, and the high fan speed blows plenty of air. If needed, there is a "super" mode on the remote that provides extra power. It is wifi compatible and can be used with their app, which works well. My Application: I have this system set up in a 2 car garage that is converted into a home gym. This 12k system is perfect for keeping the garage set to 77 F, even during the hot Arizona summers. The system runs nearly 24/7, and has been since Feb 2024. No diminish in efficiency, or increase in noise. 19 SEER is very efficient and isn't hard on the electricity bill. Conclusion: Do not snooze on this brand. The install is not bad, the equipment works great, and the customer support shines bright. And on top of that, their systems are very affordable and priced right! I totally recommend going with this option over others.

update: i put 3 of these in my old 1874 victorian with single pane windows. One is heating/cooling my bedroom and kitchen about 700sf. last night it got down to about 15f and this morning my room is 55f. sooo. i'm going to put another unit in my living room (seperated with french doors) to help heat/cool the kitchen... remember to set temp at 88f so the warm air at the ceiling does not turn the unit off when it is up to 15f cooler at floor level.... ps somewhat easy to cut line set to exact size needed but you'll need to reflare one connection... get a flare tool and good copper pipe cutter and watch a youtube on how to... can also splice two pipes together this way with a flare coupling if needed. no need to braze... i was hvac and refrigeration tech since i was 14, 1974. got my BSEE Umich. so. this is an awesome system. i just bought 3 to heat/cool my entire 2500sf victorian mansion in carson city nv. 115vac don't have to run new power lines just drill a 3/4" hole in wall and route power line into house and put a 115vac plug on the wire and plug in . put some tape on exposed wire outside to protect from sun damage, or i think i'll just use a piece of flexible conduit to get in inside. get a wall mount frame from amazon to keep condensor unit 3 ft off ground.... i live in area subject to occassional 3ft snow storms. so, this r454b refrigerant... reefer gauges for this should not be contaminated with other refrigerants such as 410a but i read the connections are the same. so you can get a gauge set (not electronic) on amazon for 410a. just use it only for this system (or get extra hose sets to change out if you use for 410a). buy a vevor vacuum pump, $80 on amazon i think, to get air out of the line set before you release refrigerant gas. make sure you understand what should be on and off on the gauge set before you release gas. vacuum out and watch for an hour to make sure vacuum is holding before you release gas. from what i read this $500 system will heat/cool about 1000sf in real world, and down to -5F outside temp. it's incredible. i will install my first of 3 next week. but based on the many many other reviews. i think this is perfect system for me. if scared of the gas, install the whole system then call a reefer guy to vacuum and release the gas from the condensor unit. i am soooo stoked to get these going. saves money over natural gas which is amazing. update. worked perfect all summer. now late november and nighttime temperatures going down. last night i get no heat . nothing. on my nightstand is temperature monitor. it got down to 57F. well i had rovsun set at 68F . guess what... at ceiling level where rovsun is it is indeed 68F. but at my bed two feet off the floor it is 57F. so easy fix ... set system at 88F and it will be about 78F on my bed... problem solved. i thought system was broken. it is not... love this thing. also. you can easily shorten the lineset provided using a flare coupler. just have to buy a flare tool and watch some youtubes. no need to braze or solder.

This thing works great. I am not an HVAC guy, but I borrowed a vacuum pump and a set of gauges, along with a flare kit and success! Mounted the head unit poured a base for the outdoor unit then installation was simple. Set the outdoor unit, cut and flared the lines on the cut end, hooked them up drew a vacuum and checked the gauges an hour later no leaks. Removed the gauges after cracking the refrigerant for a second. Finished releasing the refrigerant and it worked perfectly. Did this in April, has been running ever since as a dehumidifier at our snowbird home. Neighbors have been checking it and it is working well. Would highly recommend, but do the installation by the book for longevity.

Works great at cooling my large bedroom. Cool 69 degrees every night for sleeping. Put it on an existing 20 amp bedroom circuit. No issues of tripping the circuit with the TV lighting or even to run the vacuum. Very energy efficient. No noticeable change in my electric bill. Would be a perfect 5 but the wi-fi is absolutely useless.

Worked wonderfully at first, but after a few months it developed an incredibly annoying buzzing noise whenever it's in operation, on the indoor air handler. I've tried to diagnose it and it seems like the motor for the blower is just going to do this from now until I can afford to replace the whole thing. It's unbearable.

minisplits are amazing they save on electricity as they run on 110 instead of 220 yes you can get an adapter plug and plug it into your wall socket no electrician required they run so silent you cant hear them but heat and cool faster and better than the giant heat pumps that take up your back yard the external unit is the size of a medium size suitcase and you can watch a video and install it yourself in under 2 hrs using a drill holesaw allenwrench level and pencil no a/c man required as the unit is precharged w/ coolant i do recommend installing external unit on the ground instead of using the wall mount bracket as it can sometimes start a vibrating hum we live in the arizona desert with summer temps around 110-120 for a few months and i would never go back to an hvac system they are crazy expensive loud and inefficient i could buy 7 minisplits for the price of 1 hvac do the math!

To start the unit came in two shipments no surprise, slight damage to cardboard boxes on both. A few minor dings on exterior unit, and minor damage to aluminum fins. Nothing major or enough to try to return it. (Used credit cards to straighten some out) On to install, read everything, then read again, watch a few U-tube videos on it. Don't rush, think it over / plan it out. Figure out where to install inside unit and make sure lines are able to reach where you are placing outside unit. Moun wall bracket drill hole in wall for lines. Install inside wiring for it ( follow instructions) carefully bend copper lines to fit though hole and drain line. Guide though hole, install insulated lines with sealant (some was included "I bought a bottle in advance 🤭") don't ham fist fittings. Install/ locate placement for outside unit, hookup lines to it using sealant too. Hookup exterior wiring to unit and exterior power disconnect. Pressure test lines "checking for leaking at fittings" and purge "vacuum lines" disconnect vacuum pump and replace cap. Remove other caps release gas into system, replace caps on valves. Turn on power, go test system and enjoy your new A.C / heating unit. "I couldn't hear it running and thought it wasn't working" at first until I noticed it blowing curtains and cool air. Side note on remote there is dip switches in back where batteries go that control A.C./ heating. Now I noticed a substantial difference in power usage from other air conditioning units. In prior 5 weeks I had used around 600 k.w. now with this unit I had only used 8 k.w. in 2 days with temperatures over 95° F outside and inside temperature with it a 69-72° F. VS keeping inside temperatures 72°-80° F with other air conditioner. A friend of mine who has a different brand mini split that cost him 3 times as much. I will try to update after I have used it for some time. 3 Sept 2023 Update: I've been tracking my power usage for last month now and have reduced my usage by 3 KW a day or more. The temperatures have been up 100f and it's been keeping the inside temperature down to 67f at times, I've had to turn unit up due to getting cold. 🙂 having the unit set at 74 or 75f the cabin stays about 2° cooler than unit temperature setting. Wonderful to be able to come inside to cool off. 8 May 2024 Another update. After use though a "winter" I use that loosely "living in Southern state" but I did have some cold weather down well below freezing. It did perform OK for heat, but I did crank on the propane heater some. I used less than 20 lbs of propane though. I've already had to turn it on for A.C. a week or so now. Cleaned air filters a few times too. Definitely don't let them get clogged up with dust, pollen and dirt. Still saving money with it. VS other options. I used not even half of the power as last year. So in general it has cut the electricity usage in half or better. " the blue tab" in 3rd picture is some painters tape I have to clip on air freshener to, and to be able to see if it's running. The vent closes when turned off though.

First off, extremely happy with the performance and look of this. I installed myself in my shed/office/workshop and I went from temperature swings between 32 and 105 degrees to not wearing a beanie first thing in the morning or having sweat pouring down my face during video calls. My biggest beef by far is that the "Auto" mode has no spread between heating and cooling temperatures - all you can do is set one temperature and the unit will match it. If you would rather have it heat when some low temperature is reached and cool when some high temperature is reached, you're out of luck. So, for example, my shed is cold in the morning and can get very hot in the afternoon, but I'm comfortable in a 15-20 degree middle range where I don't want to waste the electricity to run the unit to meet some the magic, Goldilocks temperature. My choices are to set the one temp, or set up the timer functions to switch from heating to cooling and back for the morning, afternoon, and evening. But, that doesn't solve the energy-wasting problem, because, even if you set the Cool mode to, for example, 78 degrees, with the fan mode set to "Auto" or "Mute" (or any speed), the fan runs all the time, even if it's 32 degrees in the room. Even with the unit in Eco mode. The thermostat turns the cooling and heating on and off, but not the fan. This makes zero sense to me. On the installation, the manual assumes you know what you're doing and have a vacuum pump and the needed r410 fittings to pull the refrigerant. I bought a cheap pump kit from Amazon and it came with various fittings, none of which fit the unit. And, they are non-standard flare fittings that you cannot just pick up at the hardware store. And, because the manual doesn't tell you that the fittings are "r410" compressor fittings, it was a pain to figure out what I needed - a simple "here are the tools you need and the sizes" would have been immensely helpful. Once I had everything I needed, the installation was a snap. Obviously, you get what you pay for when it comes to support. There doesn't seem to be a Q&A section on Amazon or an email address to reach out to Rovsun. So, if you're willing to figure it all out on your own, you can make it work.
