    Frequently Asked Questions

    A MRCOOL mini split system is a highly efficient, ductless heating and cooling solution that allows precise temperature control in individual rooms. It consists of an outdoor unit and one or more indoor units, providing flexible and energy-efficient climate control for your home or office.

    MRCOOL mini split HVAC systems work by transferring heat between indoor and outdoor units using refrigerant. In cooling mode, the system absorbs heat from the indoors and releases it outside, but in heating mode, it can extract heat from outside air and bring it indoors. This ensures efficient operation can occur, even in cold weather.

    Installing a MRCOOL mini split system offers numerous benefits including: high energy efficiency, precise temperature control, quiet operation, and the ability to heat or cool specific zones or rooms. They are easier to install than a traditional HVAC system and provide a versatile solution for various applications, from single rooms to entire homes.

    MRCOOL mini split air conditioners are designed for easy DIY installation. The systems come with comprehensive instructions and pre-charged line sets, eliminating the need for specialized tools or training. However, professionsla installation services are recommended for those who prefer expert handling or have complex installation requirements.

Mini splits can transfer heat in both directions, making them ideal for both the Summer AND the Winter months.

    Important factors to consider are:

  • The size of the area you want to heat/cool (Square Feet)
  • Your local climate (Do you experience prolonged periods of extreme heat or cold?)
  • Basic sizing based on spuare footage alone:
    • 12K BTU = up to 500 sq ft
    • 18K BTU = 450 - 750 sq ft
    • 24K BTU = 700-1,000 sq ft
    • 36K BTU = 950-1,500 sq ft
  • Because of the extra filter density required to meet the HEPA specification, HEPA filters only work well at low airflow levels. It is not practical to fit a HEPA filter to a residential spilt-system air conditioner, as they deliver much greater airflow volumes than dedicated air purifiers. Air flow restriction form a HEPA filter, could cause underperformance or failure in a mini-split or other residnetial spilt-system air conditioner.

    Single Zones:
    • The 4th Gen Single Zone 12K - 24K condensers operational range for heating is -13°F - 75°F (outside temperature), cooling is -13°F - 122°F (outside temperature)
    • The 4th Gen Single Zone 36K condensers operational range for heating is 5°F - 75°F (outside temperature), cooling is 5°F - 122°F (outside temperature).
    • However, indoors - at the thermostat - on all Single Zone units te temperatures range for cooling can be from 62.2°F - 89.6°F and heating from 32°F - 86°F.
    Multi-Zones:
    • The 4th Gen Multi-Zone 18K - 36K condensers operationsl range for heating is -13°F - 75.2°F (outside temperature), cooling is 5°F - 122°F (outside temperature).
    • The 4th Gen Mutli-Zone 48K condensers operationalrange for heating is 5°F - 75.2°F (outside temperature), cooling is 5°F - 122°F (outside temperature).
    • However, indoors - at the thermostat - on Multi-Zone units the temperature range for cooling can be from 62°F - 90°F and heating from 32°F - 86°F.

    The max length depends on the unit that is being installed.
