ROVSUN 9000 BTU Wifi Enabled Mini Split Air Conditioner & Heater with Inverter, 19 SEER2 Energy Saving 115V Ductless Split AC Unit with Pre-Charged Condenser, Heat Pump & Installation Kit

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.

Easy install and works great. Read some reviews where people were upset they had to get a vacuum pump and use it. People need to research what they are buying. And 120 bucks for a pump vs what an ac tech would charge for the install. Just get the pump. It’s an easy process to use it. Instructions are clear or there are several YouTube vids out there. Easy power requirements as well. Only need 120v 20a. Once installed start up was simply turning it on. And cold air come out!! And quiet. Barely hear the inside air handler. Cannot hear the outside condenser. Way way quieter then a normal ac condenser Couldn’t be happier. Especially for the price point. Just need to see how reliable it is over time. Will review again after one summer in south Florida. One thing I didn’t like was the tape it came with. So just bought some better tape with adhesive to wrap the line set. Other than that saved hundreds on what an ac company quoted. They quoted a durastar for 2800 installed. I have less than 600 in this one. A friend has the durastar and so far don’t see a difference. Live in a manufactured home in Florida. Last three years hurricane flooding destroyed the under house ducting.have Replaced that twice at 2000 a pop. The duct pretty much sits on the ground under the home. No room to raise it. Last time just ripped it out and put window units in. Obviously loud units. Replaced a bedroom window with this. If this lasts like I am hoping will buy more next spring and replace all window units. And already have a pump lol. And mounted these high up on the outside so any flooding is not a concern. At least for the ac.

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.
