  • Truly DIY
Style: 24k Size: 4th gen
I purchased this with some curiosity whether it was truly DIY and was pleasantly surprised that it was. You do have to have electrical knowledge or have an electrician do the wiring. The instructions along with some Youtube videos definitely helped. I am pretty handy overall but I found this to be pretty straight forward to install. For function it works fantastic. I have it in a very well insulated Workshop, but it maintains the temp and humidity better than expected. on a 30 degree day it was blowing 95 degree air when demanded. It did struggle when temp was below 15 and could not maintain 62 degrees at night. It was routinely going in to defrost mode and during that time it isnt heating. I was not surprised by this heat pumps routinely struggle in low temps this does better than an older mini-split system i have but still isnt a heater during very cold periods. ... show more

  • Mr. Cool Split 12k BTU is amazing!
Style: 12K Size: 4th gen
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. ... show more

  • 12K BTU 4th Gen, Easy install. Highly Recommend!
Style: 12K Size: 4th gen
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. ... show more

  • Very impressed with low ambient temperature heating
Style: 12K Size: 4th gen
I installed my 12K 120 volt unit in April of 2023. It took me about two 8 hour days to install the unit myself. We enjoyed a nice cool house all summer with no issues. Once room temperature is reached this unit just quietly pours out enough cold air to maintain the temperature. The outdoor unit is very quiet, nothing like our 240 volt compressor which is very loud. My wife was concerned that MrCool would not put out heat below 45% from misc. articles about heat pumps she read. Well, MrCool has come through very well. Today I heated the house when it was 41 degrees outside, the unit was producing118 degree hot air at Turbo speed. Super impressive. We have not used our gas furnace yet this season. We have already saved money on our cooling bill, now we are hoping this winter we will save money off our gas bill. I have set up the electrical supply for the compressor so that I can use my 3000 watt inverter to supply power in case of a power outage. This is why I chose the 12k 120 volt model. Our city has added regulations on burning in wood stoves so we wanted an alternative emergency heating unit, MrCool fits the bill. ... show more
