MRCOOL 12,000 BTU WiFi Smart DIY Star 4th Generation Ductless Remote Controlled Mini Split Air Conditioner with Sleep Mode Function, White

Well, so far….so wonderful! We watched videos and read the instruction, first of all. Hubby then laid out all the parts and they were all intact, well packed too. He then poured a concrete pad for the outside compressor and allowed it to dry and cure. Once he knew everything was ready, he took his time, a few hours, and installed the unit. WOW, AMAZING! Both inside and outside units are whisper quiet; can’t really hear the inside unit on the other side of the room. When I returned home from work, we installed the USB unit so we could control the system remotely from the app and from Alexa….this is great!Please be sure you take your time and follow instructions. Watch some YouTube videos, good ones, because there are definitely some lousy ones that will get you into trouble during install. All said and done? The install was easy and this unit will save you so much money because you don’t need to hire a pro.Cooling and Heating is so comfortable, without blowing hard or loudly into the room. The fan mode works well, as well. Right now I canno say enough about this system….wish we would’ve purchased this years ago.Good luck and I hope you enjoy your Mr. Cool as much as we do.Will add indoor pics soon.UPDATE: We’ve been using this unit daily and are absolutely impressed! We live in the desert so this time of year morning temps are in the 40s and daytime in the 80s, therefore we use AC and heat in the same day and this Mr. Cool is impressive, to say the least. I’m so hoping it is quality and holds up because we’re so happy with this purchase.

I am handy, but never installed a heat pump before. I am pleased to say the MrCool DIY product installation was a success.Spending the extra $$ for the efficiency seems worthwhile, and both the interior and exterior unit are surprisingly quiet. The Internet device was also easy to install and use (but I wish it had Apple Home support).This product still gets top stars for my review, but here are some tips to be helpful to others:- The cardboard template was a bit off, specifically regarding the cutout hole. This left the unit tipsy, so it leaked on the left side; the solution was to rehang the interior unit based on the outgoing pipes that forced the unit up.- I purchased an HVAC torque wrench ($95), but in hindsight I could have probably estimated the tightening.- I was worried about bending the cables, but it turned out OK as long as I was careful.- The exterior duct cover came with 90° bends, but frankly this is wrong since the drainage line should always have some declination. My solution was to add an angle in the horizontal exterior run.The attached picture shows the unit mostly installed before adding vinyl wrapping to the coiled items. I am planning on screwing the unit to the stone supports, but need a mortar drill bit.Overall, my out-of-pocket costs (<$2K) are significantly less than the professional estimates ($5K-$6K). THANK YOU to MrCool for offering a handyman-friendly solution.

Where we live getting any HVAC technician here, let alone a qualified one, is nearly impossible. With MR Cool that becomes a non-issue. I have installed 2 myself, assisted on 2 others and consulted with several more installations. Mr Cool has things figured out to the point I think even a moderately experienced DIYer would be able to read the instructions and figure out installation. The units themselves work flawlessly. They even work into single digit temperatures, not quite as efficiently, but that is to be expected. The phone app is great and let's us control the units to warm up or cool down the rooms which are in a separate part of our building. Our newest unit is less than a year old but our older unit, a 3rd gen, has been in for over 2 years without a problem.

Was quoted $4K - $5K for a new mini-split from a local HVAC contractor which wasn't in my budget, so i figured i would give this Mrcool unit a try. So far I am very happy with this system! It worked flawlessly on initial powerup. I had some difficulty trying to get the wireless function to connect with the app on my phone, but after 4 tries it finally worked (Love this feature)!Installation was fairly simple for someone with mechanical skils. Instructions were very detailed but there was one flaw I found that should be addressed in the process. They state after you have tightened the copper connections, to do a leak test. Then they tell you to cover the connections with the supplied tape. Later in the instructions after yoou start up the system for the first time, they tell you to check the piping connections for leaks again. Well, that's difficult to do since you've already wrapped the connections with tape! I would suggest not wrapping up the connections until after startup in order to recheck the connections as suggested in the instructions.I still am very impressed with the system and it's easy self install, saved a bunch money! Now we'll see how durable it is for the long haul, i'll update with any issues at a later date.

Horrible horrible customer service. Had issues with freezing lines and condenser icing over. Had HVAC out to test the unit no leak still freezing call cust support wants it tested for leaks (already done, pressure tested, evac, and recharged all to the tune of $800 ), wants us to get a sniffer $200 for leak detection, done, no leak detected. Wants HVAC back out to another service call to the tune of $125+. At this rate could have bough a whole new unit. It’s just going in circles with “there’s a high call volume someone will get back to you”. Everything will be noted internally. Hope “you can get the help you need.” Also, nothing will be reimbursed.
