Review from an HVAC professional
Set name: 12000BTU, 115V, 20SEER2 - WiFi
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 nee
ded 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.

gauges for r410a work for this R454b
Set name: 12000BTU, 115V, 20SEER2 - WiFi
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.

Great, inexpensive unit. Wonderful, COLD air
Set name: 12000BTU, 115V, 20SEER2 - WiFi
First off I was hesitant about this company. Not a lot of reviews and sort of unknown by my peers, but this was hundreds cheaper than other brands. I ordered the 12000 btu unit and it arrived in 2 big boxes. I believe the shipping company may have shipped it upside-down, as it arrived on its head for
the outdoor unit. This is important as after the installation I had some issues. Installation was pretty straightforward and not difficult. The biggest issue was figuring out my homes older wiring process, so I verified with a mulitmeter and connected to a cutoff switch connected to main power fuse box. The other issue was putting a hole in the wall of my living room. The instructions were laid out pretty good, I also measured a few times and made a template for the hole placement for the drain and high and low pressure lines. Mounting was easy, just like hanging anything with weight into the studs. Wiring for the indoor unit was easy as well as the connections for the outdoor electronics. Pretty smooth altogether for installation. Everything was included for connecting and insulation. I would however suggest getting an outdoor cover for the lines, hose and wiring insulation to pretty it up and protect it from the sun. I had to build a stand with a small roof on it to protect the unit as well as keep it off the ground becuase I dont want my dogs to mess with it. I was so excited to get everything connected, leak tested, pressure tested and properly evacuated as recommended in the manual. This worked wonderfully!!!... but... **I did have an issue with the outdoor unit that I recieved which worked for a few days then started blowing warm air. We are starting to have summer days in the triple digits and I was not happy... I contacted the seller and requested a solution or refund. We went back and forth (mostly due to the message method of contact as well as the time difference) But the seller responded quickly, offered solutions, had me do some basic troubleshooting and kept in touch. They sent me a replacement outdoor unit as we agreed and within 4 days or so, I recieved it, installed it to replaced the first one and Voila!!! Amazing, much needed, cold air!!! I would hightly recommend this product and I will definitely be purchasing another for another part of the house. Great product, inexpensive and wonderful customer support.

Worth it. South East Texan
Set name: 12000BTU, 115V, 20SEER2 - WiFi
Purchased this on July 2025 now in September 2026. Both ac and heating work really well. Changed to this when my rooftop ac went out. This was a cheaper and much more efficient option. Been extremely happy with the product and the significantly lower power usage. Thank you rovsun.

DO NOT PURCHASE! VERY WEAK BLOWER!
Set name: 12000BTU, 115V, 20SEER2 - WiFi
I ordered this unit because the arrival date aligned with my travel schedule. Unfortunately, the item arrived late. Rovsun Customer Service was very helpful and responsive…until the unit finally shipped and it was too late to cancel the order. Once it was too late the cancel, customer service complet
ely stopped responding or attempting to correct the error. They offered me a discount on the unit to entice me to wait for their shipping error to be resolved. But, they stopped responding and did not keep their word. Once unit finally arrived, I installed it. Unit is very very weak. It blows very cold air, but it does not blow much air at all. It can not keep my camper (400 square feet) cool at all. Very disappointed in this unit. Terrible customer service and under performing unit. I would not recommend this product to anyone wanting to use it as an Air Conditioning. Maybe the heat works better.

Great Unit — Works Exactly as Hoped
Set name: 12000BTU, 115V, 20SEER2 - WiFi
I’m very happy with this mini split. The product arrived on time, and the construction feels solid and well‑made. I had a professional HVAC company install the unit, and they said it was very easy to set up. The instructions were included and simple to follow. The unit cools effectively and heats wel
l, and after about six months of use, I’ve had absolutely no issues. It’s been a dependable system, and I’m very satisfied with its performance.

Works great
Set name: 12000BTU, 115V, 20SEER2 - WiFi
Bought the 12k and 9k units and installed them myself. A unit has 2 boxes. Only 1 box arrived on the delivery date and the whole order was marked delivered, the rest of the boxes came throughout the next day. So if you only get a single box, give it another day or two for the rest. I'm just a DIY hom
eowner, but the installation was pretty straight forward. You'll need a vacuum pump (check if you need an adapter to attach to the unit). I did not use any nylog or anything, no leaks. Your call if you want to use something like that or not. The unit is cool and very silent, it is my first mini split so I wasn't sure if it was even on at first. Even the highest fan setting isn't very loud but my home feels awesome now. These are very inexpensive. I opted for these because I figured the labor of an HVAC tech would be around or more than a single unit. From my research, an HVAC tech probably wouldn't even look at anything other than a very expensive Mitsubishi system. If these die after its warranty, I'll just replace the whole thing. Wifi app works fine, it's kinda annoying to set it up, gotta be on 2.4GHz Wifi and all that, but it works.

Work great, simple install we have done 4 of these this summer with no issue
Set name: 12000BTU, 115V, 20SEER2 - WiFi
Like I said we have put 4 of these RovSun models 12k 110v in our home this summer and all worked perfectly. 2 of the out door units had a ding or two in the cabinet but nothing bad enough for it to bother me. Shipping is usually a day or two quicker than advertised and the two boxes tend to arrive on
consecutive days which is no big deal other than it shows delievery d when you only got half of you order. Manual is plenty good enough, wiring is dead simple with every wire numbered. I suppose these are a value based unit for sure but once installed they do the same thing the local hvac rip off company quoted $9000 to do for one unit in our bedroom. Been extra hot this summer in south Florida and these were life changing. Very satisfied. Hope the none of em die the day after I hit send on this review. These whole units are so cheap they cost less than a service call from an hvac company so if you cannot tinker around and fix something when it breaks some day, I consider them throwaway units.
