DIY Mini Splits are a type of air conditioning system that allows you to cool or heat individual rooms or areas of your home without the need for ductwork. A DIY Mini Split consists of an outdoor condenser unit that connects to one or more indoor air handling units through a small lineset, which contains the refrigerant lines, electrical wiring, and condensate drain.
MRCOOL is the most popular brand of DIY Mini Splits as they offer the longest warranty and highest quality units. They are a cost-effective and energy-efficient alternative to traditional HVAC systems, particularly for homes without existing ductwork or for homeowners who want to control the temperature of individual rooms separately.

Works great
I got the 12k unit, install was very easy and the unit is working great and keeping the room cool. It helps the main central unit not have to work as hard. Real happy with it so far.

Looks good
Makes the line set look better, easy to install instructions but installing on brick is kind of difficult.

Nice Unit, Easy Intall and cools quietly
Nice unit and easy to install with good skills and the right tools. Nothing elaborate...Drill with 2.5” hole saw, bubble level, proper size wrenches, misc. hand tools and some latex caulk. I did purchase separately the line set channel, electrical disconnect to meet local code and ¾ pvc for condensate drain. Although the kit gives you mounting screws, I used lag bolts for my indoor unit mounting. I used the channel and the pvc for installation and aesthetic purposes. The pre-charged lines are nice eliminating the need for evacuation. From start to finish the installation took just under 5 hours. I still need to complete my permanent electrical power (picture shows temporary electrical power). The unit runs very quiet and I do like the features. What I am not a fan of is the Communication to the App. The unit only communicates at 2.5Ghz. I have split my home network into two; 5GHz and 2.5Ghz and still cannot connect. I followed all the steps in the tutorial. It seems I have spent more time on that than the while install. That is my only complaint with the product as the App is supposed to have more features available than the remote. Otherwise, I have recommended the product to friends.

The pre-charged lines allowed us to install this heat pump with no special equipment.
The pre-charged lines allowed us to install this heat pump with no special equipment. They seem to be well designed and work as intended. A torque wrench is recommended to make sure that you get these just tight enough.
