DIY Gen-3 18,000 BTU 20 SEER ENERGY STAR Ductless Mini Split Air Conditioner & Heat Pump w/ 25 ft. Install Kit 230-Volt

This product is amazing! It’s great for the extra building and shop that we have! Works great!

Read the instructions carefully.

We have a 400 sqft south-facing sun room that will hit 90+ on any normal sunny day. Basically unlivable. Tried a few mobile AC units and none could keep up. Not the case with this unit. It's not instant cold but it gets there. The unit was better built than I expected and wasn't impossible to install although it had me scratching my head a few times. Typical installs have the refrigerant lines go immediately into the wall behind the unit. Not ours. I had to run them along an exterior wall, out thru a 8x8 support pole and then out along the exterior wall. The vinyl line cover made working with the lineset a challenge and making the 90 degree bends was a process but it did eventually work. The Mr Cool cover set was okay but the joints are sloppy, workable, but a bit sloppy. Wiring was easy and straight-forward. Hanging the inside unit once the lineset was installed wasn't fun because the adhesive insulation around the connections is bulky but it fit inside the unit. Barely. Interior unit is very quiet and doesn't vibrate thru the wall. Fan speed isn't as fast as I expected but the Turbo option definitely helps. Exterior unit is also very quiet and has virtually no vibration. Overall I'd give it a solid 6 on a 10-point 'hard' scale only because of our situation. As others have suggested put up your cover first. Take your time making the bends. And enjoy the cool air!

18k btu model here. Below 30 degrees, this thing is going to struggle. If you're looking for something as a primary heat source in colder climates, get something different. It's 16 degrees outside and this thing is struggling to keep a 500sqft room at 70. Install was easy and i was up and running in a few hours. If you have something else to use as a backup for the really cold days and don't want to spend 3x more this is a great buy. Overall, I'm happy.

I was able to do the whole install start to finish with no problems. I highly recommend this for anyone! Very happy with mine!

Putting the unit in was not hard, just make sure you have your spots picked out for both the inside and outside unit, make sure there is no wires or studs before putting your hole through the wall. You will need to run a wire for electricity and install a quick disconnect or hire a pro if you don't know how. The unit cools good and is very easy to operate. The only problem i have is with the internal thermostat, if i set it for 76 the unit will kick off at 73, but will not kick back on till 79 degrees. That is way to much of a temp difference for my liking. I have ordered a ir wifi thermostat, hopefully that will fix the problem. The interior fan also runs all the time when in cool mode, idk about heat mode. I have only had the A/C for a week

I bought the unit from Home Depot Online at the end of April 2020. In fact, Home Depot had the best price on the market. The shipment wasn't very smooth though since the indoor and outdoor units arrived on different dates and one of the boxes came with scatches. The unit however was intact. The installation was relatively easy as advertised (perhaps 6 hours total through a couple of days... in my case). The area intended to cover was around 900 square feet. During the two and a half months of being in use, I have nothing to complain about since it is working just fine and operating very well considering the Southern California summer heats. I'm glad to also notice that it is actually energy-efficient since my electricity bill has not gone up more than about $20- $25 over the previous charges. The only reason for not picking 5 stars is because of the technical support. I contacted MrCool about a month and a half ago because of a defective SmartHVAC device (the connection to WiFi) and I'm still waiting for the replacement. I also asked to purchase the 3-year warranty on the same occasion and I still have not received any response. Other than that, I am very satisfied with this purchase.

Very straight forward to install and works great.

Absolutely love this mini split air conditioner. Works amazing! Definitely recommend!

3rd gen better than last and easier to install. Quiet and effective
