When sizing your MRCOOL DIY mini split, it is important to consider the following factors:


The size of your living space

    The size of your living space, the square feet is an important factor to consider when sizing your MRCOOL DIY mini split. The square footage of the room will determine the BTU unit rating required for efficient heating and cooling.

    The BTU unit rating

      The BTU unit rating is a measure of the heating and cooling capacity of the system

      The SEER efficiency rating

        The SEER efficiency rating is a measure of the system's energy efficiency. The higher the SEER rating, the more efficient the system is at using energy to provide heating and cooling.

        The cooling and heating capacity

          The cooling and heating capacity of the system is another important factor to consider when sizing your MRCOOL DIY mini split. It is important to ensure that the system can provide sufficient cooling and heating for your living space. 

          The line set length and communication wire

            The line set length and communication wire are also important factors to consider when sizing your MRCOOL DIY mini split. The line set length will determine the distance between the outdoor unit and the indoor unit, while the communication wire is used to connect the two units.

                  When installing the indoor unit, it is important to ensure that it is placed in a location that provides even air distribution throughout the living space. It should also be installed at a height that allows for easy access and maintenance.

                  Mounting plate installation

                    The mounting plate is used to securely mount the indoor unit to the wall. It is important to ensure that the mounting plate is installed correctly and securely to prevent any accidents or damage.

                    Quick connector installation

                      MRCOOL's patented pre-charged quick connect line sets make installation easy and efficient. It is important to follow the installation instructions carefully to ensure that the quick connectors are installed correctly and securely.

                      Condensate drain line installation

                        The condensate drain line is used to remove excess water that is produced during the cooling process. It is important to ensure that the condensate drain line is installed correctly and that it drains properly to prevent any damage or moisture buildup.
