This product is as advertised and I found it to exceed my expectations performance wise. My only suggestion would be that the product be available with a couple of different lengths of control/feeder lengths between the outside and inside unit. My installation had a very short distance between the inside and outside unit so had to coil up a large amount of tubing.

I'm 73 years old. I bought this to heat and cool my 24' x 36' x 14' ceiling workshop. I read the detailed instructions and watched a couple YouTube videos. I had never worked with HVAC prior to wiring and installing this unit, It was easy to understand the unit and its installation. I installed it by myself (there were a couple steps that I could have used a little help). So far, so good. I've been through a -12 F night with no issues. Love it.

Unit works great. No issues. Installation was a breeze As well. One thing needs improvement is the quality of the mounting bracket. It seems since i chose to run ac lines to go threw the wall on the left of unit instead of standard right side it barely fits in space provided. Braket bends away from wall n now gap between wall n unit has increased so it is no longer flush to wall. I removed, bent it back and reinstalled but happened again.

If you're handy, the installation is fairly easy. I had to hire an electrician to install an outside disconnect. The unit works great and the iPhone apt is a really nice feature so I can cool the place before getting there! I chose to cover the outside lines with wood rather then plastic and painted it the same color as house. It blended in perfect.

Installed a DIY 24K MrCool fall of 2017, flawless operation both heating and cooling modes ever since. Installed a DIY 18K MrCool at my other place four months ago and is working as well as the other one. Haven't used it in cooling mode yet. In both installations the indoor unit was a struggle to hang onto its mounting bracket. It has to slid down onto the metal tangs and I and my helper just had to keep trying until it seemed right. Otherwise not too hard to install.

Purchased this unit because it is DIY (only one on the market), the 110 VAC/20A feature, and superb 5/7 year warranty. Ran the hoses through a hot water heater space inside of 3" ABS. Will use 4" next time, was somewhat of a challenge to thread. This is my 3rd install, intend to purchase 4 more units. Central HVAC is a waste of money and very inefficient in a large expanded floor plan with moderade annual temperatures. I love this product..!

Great unit. It cools and heats my 24' by 46' (insulated) shop with no problem. Installation was easy and it looks nice on the wall. It is super quite. On the first day of start up I ran the diagnostics as instructed and it passed all of them but the next day the display had an EE error which was low gas. Even with the error it was working fine but I called an HVAC and he added gas. This condition may have been my fault if I lost some gas while making the connection. You should plan ahead for any extra line set that you may have. I coiled my extra lines on a hose reel mounted to the outside wall; it looks OK. One of my best buys.

I bought and installed this unit last September. I have used the fan, the heater and the air conditioner without issue. The AC is quiet and cools the room quickly. The heater is a little bit louder and has a bit of shake in it (most likely because I should tighten the bolts down a little more). Otherwise, very happy with this unit.

Have no complaints at all works great I have it in a 600 sq ft building and heats and cools great FYI I live in Tx so like my home state of man I would do more research on heating with it. In the summer I mostly keep it on the dry setting witch is dehumidify and it works great. Simple installation I did it by myself.

heat portion of the unit works great during mild winter temps. It defrosts every thirty minutes or so then returns to its heat mode. Have not used cooling mode yet since it was installed in October. Very quiet and I think it will be a great addition. Keeping my 1200 s.f. garage/shop useable at 65 degrees. Outside air in low 30's.
