Disappointed

Our unit was under warranty and the futting that one of our lines hooked to, sheared off and bled the system. This drained the entire unit. You sent me a new fitting and one line. It as basically still empty of coolant, and will not work. One problem caused another problem and it wasn't resolved. I went with this company because it was supposed to have a great warranty if I did have any problems, which I did, and they weren't resolved. The local hvac company charges $600-750 to charge that unit, depending on how much coolant it needs. As a business owner, I stand behind my products, why can a big company like MRCOOL stand behind there. Very sad.

MRCOOL DIY 12K BTU 23.5 SEER2 5th Gen Ductless Mini Split Heat Pump System - 115V

I ordered 2 of these units for 2 small cabins in the TN mountains. Not counting non mini split time, each took between 3 and 4 hours to install.
This was the hottest weekend of the year, and not cabins were chilled in under and hour.
These are the complete DIY bundles. Do yourself a favor, and don't try to save a few bucks by trying extra work with other "almost DIY" configurations. EVerything is in place with this bundle, and the unit is light enough to make it a one person job.
A few tips, if you are using 10 gauge wire, gets some space connectors for your inbound lines. Make connections easy.
Remember to unpack both boxes. One part you need inside is in the outside box 😀
Keep an eye on the drain hose. Kinks easily.
Make sure you have a good circle hole saw.
Spring for the disconnect box and a whip. Beats running conduit.
Figure out if you really need 25' lines and be prepared to have a plan for accommodating the extra.
CHILL sent me exactly what they said they would send. It was on a pallet that the shipper loaded directly into my truck. The only snafu was a missing whip, and CHILL sent that out immediately, so I had it before I was even onsite to install.
Overall a great experience, and many, MR Cool is cool.

First month review

After using window units for the past 10+ years, I installed our first single zone unit for our home. Could not be anymore happy with the install process and the functionality of the unit. Extremely quiet and cools the 2 room (kitchen/dining area) so much better than a noisy window unit. The outside condenser unit is much more quieter than I expected. Cannot wait to install a bigger multi-zone unit for the rest of the house. Thank you Mr. Cool for making a self install cost efficient product for us DIYers!
