MRCOOL 18000 BTU 230V Ductless Inverter Mini Split Air Conditioner & Heat Pump System, Advantage Series - Wall-Mounted AC Unit w/Heating and Cooling for Home, Office & Commercial Space

Really love this unit. It heats and cools our small space here in Florida and keeps the electric bill down too. The app controls it when away or at home although quirky. The remote control is great. It was fairly easy to install and doesn't take up much space. Lots of YouTube videos show you how to do it. You have an inside, small hang on the wall unit, and a small outside unit. Very quiet. We don't even know if it's running or not until we walk up to it and feel if air is blowing or not. Really can't hear it run. No problems with it and I would buy it again.

This item is NOT the Do-It-Yourself Model. Even though the guts are identical to the DIY, it takes more thought and effort to install. You need some special tools, like a vacuum pump, a good flare tool, tubing benders, and some beforehand practice with the flare tool to do it. If you take motors apart, build machinery from scratch, or are a plain dedicated do-yourselfer, you can do it. If you're not willing to invest the time studying up on it and practicing with the flare tool, you'd better forget it. Go with one of the DIY models. Mine works great. I have an 18,000 BTU model installed in a 700-square foot (insulated) garage.The temperature drop across it is about 38 degrees (if room air is 80F, output air will be about 42F). It has no problem at all cooling the place down quickly. It appears to be very smart, only putting out the temperature needed to maintain the setting. It may start out at 42, but after 20 minutes it might be doing 58. The fan is nearly silent.

First and foremost, this is not a do-it-yourself unit, unless you have HVAC equipment and watch plenty of YouTube videos. I thought it was the DIY unit when I purchased it so I had to learn how to install it. I am using it in my garage in the Chicago area and this 1.5 ton is a great performer. No need to run consistently but when heating or cooling is required it gets the job done. In the heating mode the outside unit is a little noisy but I hope to eliminate that when I insulate and drywall the garage, but the inside unit is super quiet. The wifi works as advertised and operates from my smart phone from anywhere. The wireless remote does not communicate over or with the wifi and takes a few extra button pushes to get it to respond. I purchased aftermarket air filtering sheets and I was shocked at how fast they got dirty. Worth the few extra pennys in my opinion. Overall, I absolutely love it.

I bought one of these units 4 years ago almost to the day. Within 2 years the control board failed, which to their credit they did provide a new board under warranty ( parts only, not labor). Now two years later again, the compressor has failed (not under warranty). I have to say, the company tech support is great and very responsive, unfortunately their product seems to be junk.

The outside unit was easy to install on the outdoor wall brackets. The indoor unit a trained installer. What should have been easy was a real pain, because we had to have the pipes and wires exit the box on the right hand side as you face the unit. The system is set up hot the wiring and cables to exit straight out through the , or exit on the left. What should have been an hour job took four hours. That said, the unit works perfectly. Great cooling, super quiet. No electric bill yet, but this unit sure earned its keep over the series of 90 plus days. Handled the humidity perfectly!

We have an addition on our house that gets ridiculously hot in the summer, which is unfortunate seeing as it's the main gathering area for our family. It is roughly 400sqft and when it is 95⁰ outside it is usually about 86⁰ inside. I purchased an 18k unit to cool this room and assist with the central air in the rest of the house and boy has it delivered. I recieved my shipment at about 3pm on Thursday and by about 6:30pm or 7pm I was able to have it completely installed (minus the electrical). I got the electrical hooked up the next afternoon and the room was already around 78⁰ degrees and climbing. I flipped the breaker and the indoor unit light up. I followed the instructions regarding the initial run protocol, after that I cranked it down as low as she'd go. It took roughly 30-40 minutes to cool the room down to 68 degrees. I purposely oversized this unit to assist with my undersized central air unit and have found it to work as advertised. I find the remote to be very user friendly and straight forward. The app on the other hand seems to be a little less refined. It often times doesn't show what temperature the unit is set at and doesn't sync with the remotes, so if you change a setting on the app the next time you touch the remote it will jump to whatever settings you've selected on the remote. Also from what I can see the unit does not display the current room temperature anywhere. This isn't a huge deal for me but there have been times so far that I have it set to 73⁰ and it feels much, much cooler. Maybe this is due to the fact I'm used to 88⁰ temperatures. Overall I'm extremely happy and satisfied with this purchase and am probably going to save up so we can install a multi zone unit in the rest of our house.

Basically, works as advertised, easy to install, liked getting the pipes with the unit, used it for last five days and keep adjusting the temperature up as it cools wonderfully. Replaced an older unit and this is quieter, cooler and cheaper - smaller and lighter too but with more capacity.

The mini split is working very nicely. Had to get a A/C installed by professional. To have the line from outside to inside vacuum, to make sure no air in the hoses. But it saved me from having to install myself I’m an electrician but didn’t want to chance damage to the hoses.
