Mr Cool has great support for/post install

This unit has great install instructions as well as technical support after install. Unit is large but looks good and has a modern LED display. Best warranty you can find on a DIY unit and even after an issue with a leak the customer service responded quickly and fixed the problem. Looking forward to having this for many years.

Fantastic experience

So far so good! I installed this mini split to replace another brand mini split that was already installed in a house I purchased. The old mini began intermittently freezing over the coils and connections in the outdoor unit.

We love this!

I contacted premium home source about what size I needed, I got a response within a hour which I would assume was after hours and they recommended the 18k. Well I up sized to the 24k 4th gen just because I figured up sizing couldn’t hurt. I was impressed on how easy it was to install. My father in law and I had this up and going in less than 2 hrs on and a Friday. Super quiet and cool the house down quickly. Wish I would have bought it sooner! Thanks

Died after 2years 3months

It was easy to install, and it worked great for just over 2 years. The suddenly it stopped working. No error codes, refrigerant has pressure, everything seems fine except for the compressor which will not run. I looked for a run capacitor, but there does not seem to be any. The way it is built it looks like it is a nightmare to service, e.g. it is very tricky to get access to the control board.

Trash

I installed this thing about a month ago. It worked fine until today when I woke up to my breaker being tripped. When I tried to turn it back on, it immediately trips again. There's a short somewhere inside of the outdoor unit and its completely unusable. I checked the wiring to the unit and there's no issues. Stay away. This thing is trash.

DIY+ a professional

If you are buying this to replace a mini split you may want to hire a professional. The electrical requirements for the wire gauge in the instructions doesn’t match the requirements on the actual unit. If you choose to DIY this get a pipe bender and torque wrench. The instructions have so many warnings it’s intimidating even for handymen. If you mess up warranty voided.

Money Saver / Great Product

Easy installation, great instructions and quality parts. Unit so smooth and quiet. Couldn't be happier with this product. Ordered from ACE and ready for pickup at store within days at a great price. Saved a lot of money and feel I have a better installation than I could have paid others to do. If you're a handy person you can DIY. No problem!

This thing will die fairly quickly

Bought in August 2023. App goes out of sync with the unit quite regularly. Could only use the remote control. By October 2023 we couldn't feel hot or cold air coming out of the unit. Troubleshooted and no leaks. Warranty is non-existent. It's very likely that the refrigerant is going to have to be recharged after < 2 months of install time and only a few days of actual use. Guess what isn't covered :) Have to pay an AC person to fix. Learn from my mistake, spend 1-2k more for something reliable.

Efficient and Reliable

This DIY mini-split heat pump system has transformed our home's heating and cooling experience. The 24k BTU capacity provides ample power to cool or heat medium-sized rooms effectively. The system operates quietly, ensuring a peaceful environment. We've noticed a significant decrease in our energy bills since installing it, thanks to its high energy efficiency. However, installation can be a bit challenging for those without prior experience.

Quiet Operation

One of the standout features of the DIY 4th Generation E Star mini-split heat pump system is its quiet operation. The indoor and outdoor units produce minimal noise, ensuring a peaceful living environment. Even at the highest fan speed, the noise level is bearable. We appreciate this feature, especially during nighttime. The system's cooling and heating capabilities are excellent, providing consistent comfort throughout the year.

Great Value for Money

The DIY 4th Generation E Star mini-split heat pump system is an excellent investment. It offers fantastic performance at a reasonable price. We appreciate its eco-friendly features, such as the R410A refrigerant, which reduces environmental impact. The unit is energy efficient, which translates to savings on our monthly bills. The installation process was straightforward, with clear instructions provided. Overall, a solid product that won't break the bank.

Impressive Performance

We've been using the DIY 4th Generation E Star mini-split heat pump system for over a year, and we're impressed with its performance. It effectively cools our rooms during scorching summers and keeps us warm during chilly winters. The system operates quietly, allowing us to sleep peacefully at night. The unit's reliability and durability have been remarkable so far. However, professional installation is recommended for optimal performance.

Just installed this morning!

The unit was turned on for the 1st time and boy it was so quiet I literally had to make sure the fan was spinning outside. the unit and air handlers cool very quickly. I also tested the heating it worked superb. I wont be using this until summer time gets here honestly. that's my main purpose for purchasing it. Living in the deep south requires good A/C. Premium Home Source customer service is also top notch. I would recommend anyone to give them a try. THEY ROCK!

Best $ spent in a long time

Best $ spent in a long time. Super easy install even for this 62 y.o. female. Had to have grandsons lift the units up in place but if you can read you can install this yourself. If I could change anything I would make a simpler remote with an on/off, temp up / down button and mode. I won't be using the sleep or other features the unit offers and those buttons are just cluttering up the remote. The overall system works fantastic though - couldn't be happier with the cooling - and the system is very VERY quiet

One of the best purchases I've ever made

I'm renovating an older house built in 1966. The house had central air but the duct work was disgusting. Moldy and filled with dog hair. I removed all the ducting and the air handler. I got some bibs on replacing the central air and was blown away by how much it would cost. We had been using portable ac units but my wife and I could not stand the noise and the vent going out the window. Being a DIY kind of guy, I decided to try mini split units but was not sure if they would do the job. I bought this unit and I couldn't believe how easy it was to install. I worried that it would still be noisy. Boy! was I wrong! We pleasantly surprised to see how quiet it was. It cooled the room quickly and easily. We liked it so much that we bought another unit for the garage. I highly recommend These units and intend to buy several more for other rooms.

Easy to install - happy with the units!

Installation from start to finish is simple and straight forward. My hardest part was determining exactly where I wanted to install the unit. I opted to use the full 25 feet of line set as to not have it bundled which is ok to do but I'm a stickler for a smooth finish look. I would also suggest making a punch list before you begin. I choose to pour a slab for the outside unit instead of the bracket mount or other options for my install. It truly is DIY if you have knowledge doing any electrical safely and by code. My installation took a little longer than Mr Cool's video (recommend) did but only because I ran in to a triple wall stud drilling my through wall hole for the line set. Again, it's straight forward and the end results were a room staying at very cold temperature with little to almost no noise. My ceilings fans have a higher hum than this unit. The outside is just as quiet, you have to see the fan turning to know it's running. It's only been running for a month but I feel confident it'll last. Also made a couple calls to them for clarification and they picked up the phone immediately and answered my question.

Great DIY Mini Split system

The Mr Cool system is unbeatable as a DIY guy. I was leary since I have no HVAC experience but after watching others do the install on you tube I decided I could do this! The units arrived really fast from Premium Home Source and I immediately noticed how professionally the components were packed. You could easily tell that Mr Cool takes pride in their product. Installation was rather easy following the instrictions and watching videos along the way. After completion, the unit works like a champ. I installed the the 12k unit in the 400 sf bedroom and it works quiet and efficient. Spring in Ohio has its ups and downs temperature wise so weve already used both the heat and cool functions and I am pleased to announce that my Mr Cool performed both flawlessly. I am so happy with this unit that I am going to purchase another bigger unit for our great room. I highly recommend Mr Cool. Save big money and do it yourself!
