DIY 4th Generation E Star 24K BTU Heat Pump Condenser 230 volt 20.5 SEER with 25 foot line set

The Mr Cool 18,000 BTU mini split system 5th generation system is working great. I was able to install it myself with the included step by step instructions. I also went with the Mr Cool line cover plates to protect the lines but to also give it a clean finished look.

I have had a super good experience with Mr Cool, from before questions on 'chat' to ordering and after installation questions. No doubt I would do it again.

With the crazy hot summers here in Texas, this was a smart investment!! I can actually work in the garage without passing out from heat stroke. Cools off the garage quickly, and I love the articulating discharge. My only wish was there was an option to choose a longer length for the freon lines. It dictates placement of head unit and condenser and required some landscaping outside to hide the condenser from plain view and the HOA.

So aside from some basic knowledge on how to screw in a light bulb I had never tackled anything this big, after watching some YouTube videos I felt confident enough to install it myself, the hardest part was making room on my electrical panel to install the new breaker and after purchasing some single pole 20A breakers I had enough room to put the new breaker, the second most difficult part was actually drilling a hole through the wall, simply because the drill bit was not as long and the width of the wall.Let me add that you shouldn't cheap out on the disconnect box for the outside,I initially purchased the $10 one from Home Depot and the disconnect was bent and so I had to troubleshoot from the breaker all the way to the Unit sooo get the $30 one with fuses as a double measure. The unit was installed nat the end of summer 2018 and it cooled my 1200sqft 18ft ceiling main level effortlessly. Heating is not as efficient, specifically here in Atlanta when the temp drops below 40F, the air coming out is not as hot even in turbo mode. All that being said I had gotten mutiple quotes from different contractors and they were all comming in at $4800 plus for a 14 seer 2 ton unit. Total cost of the project was $1490 for the unit, $100 in electrical supplies and $7 for the lineset cover which is basically a square plastic gutter from Ace hardware.If you were having second thoughts...don't this will save you $$$$

Purchased the unit last summer. My brother and I did the installation - it does require four hands. Followed the instructions and just like that, the unit was installed, lines charged and cables energized - the cooling unit works great, the heat too! I've had many of my friends ask about it and one just bought one for an extra room. Great product.

Easy install. More efficient than expected! We chose a model that was twice the size recommended for the square footage to make up for heat loss/gain when the garage door is opened. This unit has done a great job keeping our garage/cave very comfortable! Highly recommend!

Installed this in our fast food restaurant during a mini Midwest heat wave. Our seating area was running 89 degrees during the day!!! And could only drop to about 82 overnight because of refrigeration and “leftover” heat from appliances. Over the first night it dropped it all the way to 65 and was able to maintain 72 the next day with all the appliances on and people opening and closing the door all day!!! I'm impressed.

I have had the system for a few months now and living in AZ hasn't been more comfortable in my garage. The cars stay cooler in the summer and it's a nice cool place to hang out with friends in the summer months. I haven't really used the heater portion on it yet but I did turn it in a couple of times and the heat pump works great too. Only took a few hours to install and setup. Very quiet operation when in use. Overall I am very satisfied with the product.

Our MRCOOL 24K is installed in a 700-750 square foot living room and during the summer times (in Bellingham, WA USA), it provides an acceptable level of cooling. It is quiet and performs as expected during the summer time. But during the winter, when the temperature goes below 40s, it has a hard time keeping up with the set temperature of 72F and the temperature in the living does not go above 66F or 67F even if it has been running for hours. We need a an auxiliary heating system to compensate.

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.
