ROVSUN 18000 BTU Wifi Enabled Mini Split Air Conditioner & Heater with Inverter, 20 SEER2 Energy Saving 230V Ductless Split AC Unit with Pre-Charged Condenser, Heat Pump & Installation Kit

I installed this almost a year ago in my garage and I could not be happier. Installation was fairly straightforward, but it does take a fair amount of DIY home repair knowledge. I had my AC company release the refrigerant and check for leaks. I was going to install a condensate trap, but my AC company told me you should not do that on a mini-split system. I used a tube cover kit for the outside lines. One thing to know is that the fan, which is very quiet, is on constantly (even it the outside unit is not running). The temperature differential of the air going into the interior unit versus the cooled air coming out was almost 30 degrees Fahrenheit, which I think speaks to the efficiency of the unit. While there has been an increase to our electric bill and the electric use of the unit is hard to quantify, I believe the increase has been less that $15 per month (we live in south FL and keep the temperature at 82 degrees when I am not in the garage and lower it to 78 when I am in the garage - the temperature measurement is up at approx. 8 feet, so the temperature is lower at working levels). I did not think I would use the WIFI capabilities, but I have found the app to be quite useful, including the ability to control the unit while traveling. I have not had any need for technical support, so I cannot comment on that.

Works very well, easy too set up

Install was straight forward if you are handy with tools. This was my first attempt at installing a mini split. Probably took me a little longer than most due to removing drywall to hide all the lines. I borrowed all the tools to install. You can order a kit here on amazon for a decent price. Considering how much HVAC companies want for a simple install like this. I installed the 18k btu in a 960 sq ft garage that is fully insulated and has finished drywall. Wanted to wait until after the full summer to review. Impressed!! Beyond impressed actually. No notice of increased power bill, the garage stayed a perfect temp all summer. I was finally able to use my garage/shop during the summer. It inspired me to finish a bunch of projects that I was putting off. I don't use any of the phone applications so I can't comment on that. The remote works great. I had the temp set at 79 degrees and never turned it off until October. I haven't and won't use the heat part of the unit. It's Arizona. Quality product for a great price. Side note. I researched for months before buying. From York to Rovsun. The debate is over.

I had the electric for this unit installed by a professional electrician. I had the unit installed by a professional HVAC company. This unit worked fine for about a month and then, as the outside temperatures rose, the unit stopped working one day. I never changed the temperature, kept it on 67 every day, all day. One day I walk into the living room and I see the unit is displaying PO and E9. When chatting with the seller to discuss replacement or return they informed me this error code was due to the unit overheating. I followed each troubleshooting step and sent in all the requested photos. They assured me that they would replace the unit if it was defective. After sending in all the above photos to prove that everything on my end was done correctly, they have stopped responding. Apparently this is not covered under the A-Z guarantee, which is frustrating in its self. I spent $800 on this unit and another $600 to get it professionally installed. I would have never bought this unit if I would have known they had no intentions of replacing THEIR defective product.

Great AC/Heater unit does the job well. I would recommend hiring someone to install it for you but if you know how to install an AC unit you can install it with just two people. The design looks good and isn't loud at all. It's pretty big but I like the size. And keeps the room ether warm in winter or cool in the summer.

Easy to install, works well and the heat works great

WORKING GOOD BUT NO WIFI COMPONENT AS THEY SAID

Insalled the 18,000 but unit , very easy to do. set the Outside unit on a precast pad. Followed the instruction on Vacuming the line set, unit is so quiet if you are right next to it the only way to know its running is to see the fan move. cools fantastic. will buy more.
