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.

The unit showed up early, and although the box was punctured, the insides were fine. I took my time and read the installation manual about 8 times before starting. Not everything is covered in the manual, but was is in there is very well written and mostly easy to understand. Nothing in the manual about running tubing out the sides of the indoor unit, but one call to customer service confirmed it is set up to do that. (Why don't they explain that in the install manual?) I ended up running mine out the back. It would be nice if they explained how to actually attach the UV tape. It has no sticky back, so one is left to improvise. A little guidance would help. The drain hose they supply is very flimsy. I purchased the outdoor bracket from Amazon. JEACENT Outdoor Wall Mounting Bracket for Ductless Mini Split Air Conditioner Heat Pump Systems, Universal, 7000-18000 Btu Condenser. Otherwise, it as not hard to do most of the install myself (with a helper for last day), and it took 2.5 days total. Take your time, double check everything. UPDATE after 4 months. I am very pleased with my Mr. Cool unit. It's very quiet and hasn't increased my electric bill very much as far as I can tell. I've left it running for a month straight during this very hot summer in SC, and set at 76deg my shop is cold.

Spent a month with support going back and forth. Had to pay a local HVAC company to charge the system twice and attempt to find the leak. Mr Cool refused to honor the warranty because the slow leak could not be located.

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.

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.
