Most MRCOOL mini splits are designed for DIY (do-it-yourself) installation. These systems come with everything you need for most installations, except for electrical equipment and tools. Let's take a deep dive into what parts are included with the MRCOOL DIY mini splits and what extra parts you may need to complete your installation.
What Comes Included with your MRCOOL DIY Mini Split
In your MRCOOL DIY mini split system package, you will find the following parts:
-
Indoor Air Handler:
- Either a wall-mounted unit or ceiling cassette, the MRCOOL indoor air handler distributes air throughout your space. Inside the air handler, you will find the fan, air filter, and controls needed for optimal temperature control and air quality.
-
Outdoor Condenser:
- The condensing unit holds the compressor and condenser, and is stored outside. It is a key part of your mini split system and is built to withstand outdoor weather conditions.
-
Line Set:
- The line set is the bridge between the indoor air handler(s) and the outdoor condenser. The line sets used in the MRCOOL DIY mini splits are pre-charged with refrigerant, which makes installing these systems simple and efficient.
-
Remote Control:
- The included remote control allows you to change your set temperature and settings without having to directly interact with your unit.
-
Smart Controller Dongle:
- The Smart Controller dongle enables you to control your MRCOOL mini split through your phone, via the MRCOOL SmartHVAC app.
-
Communication Cable:
- The included communication cable allows your indoor and outdoor units to communicate with each other and synchronize the various parts of the system for the most optimal operation.
-
Mounting Template and Bracket:
- The mounting template is included as a guide for where to drill holes and place your wall-mounted air handler. The mounting bracket will then be installed in that position and will be used to support and hold your air handling unit.
-
Small Hardware Pieces:
- In the box, you will find the necessary screws, bolts, and fasteners for the installation. You will also find a small bag with extra hardware, in case you lose some during the installation.
-
Remote Control Mount:
- To reduce the chances of misplacing the remote control, MRCOOL includes a remote control holding mount that you can install on the wall and store your remote in when it's not in use.
-
Allen Wrench:
- The allen wrench in the package is used to open the refrigerant lines.
-
Neoprene:
- Used in the installation to insulate and protect various parts of the system from environmental factors.
-
Insulation Material:
- Reduces heat exchange to reduce energy loss and maintain the desired temperature within the system.
-
Sound Dampener Pads:
- Strategically designed to reduce vibrations and sound levels during operation.
-
UV Tape:
- Reduces sunlight damage by protecting refrigerant lines from ultraviolet rays.
-
Wall Sleeve:
- Helps to seal the line set opening and prevent outdoor air and moisture from coming in.
-
Drain Line:
- Prevents water from accumulating by ensuring condensate is properly drained.

-
Drain Line Extension:
- For systems placed far away from outside walls, a drain line extension might be required to properly dispose of condensate.
