MRCOOL is a popular brand of ductless mini split system that consists of an outdoor condensing unit and one or more indoor air handling units that are connected by refrigerant lines. This gives the user flexibility in placing the indoor units.\r\n\r\n \r\n\r\nMini splits that provide heating and cooling can potentially save you a lot of money compared to separate AC and furnace systems. Their targeted focus can also help reduce energy waste in unused or unoccupied rooms.\r\n\r\n \r\n\r\nIf you\u2019re interested in MRCOOL units and are thinking about installing one, it's best to learn how much power they consume so you can plan your electrical setup accordingly.\r\n\r\n \r\n\r\nLet\u2019s look at the key factors that determine how much power a MRCOOL mini split draws and compare its energy usage to other types of HVAC systems.\r\n\r\n \r\n\r\nIf you need any replacement parts for your air conditioner<\/strong><\/a>, you can use your model number to find what you\u2019re looking for at AppliancePartsPros.com<\/strong><\/a>.<\/strong> We also have thousands of free DIY troubleshooting and repair guides to help you fix your air conditioner yourself.\r\n\r\n \r\n\r\n[lwptoc numeration=\"romannested\"]\r\n

Factors that affect the power consumption of MRCOOL mini splits<\/strong><\/h2>\r\n \r\n\r\nThe wattage and amperage draw of a MRCOOL mini split depends on the following:\r\n\r\n \r\n

British Thermal Unit (BTU) capacity<\/strong><\/h3>\r\n \r\n\r\nThe higher the BTU rating, the more powerful the unit is at heating and cooling and the more energy it\u2019ll use. MRCOOL offers mini splits ranging from 9,000 to 36,000 BTUs.\r\n\r\n \r\n

Model type<\/strong><\/h3>\r\n \r\n\r\nEnergy use can vary slightly between model lines like the DIY, Do-It-For-Me, and Signature series.\r\n\r\n \r\n

Outside temperatures<\/strong><\/h3>\r\n \r\n\r\nColder external temperatures in the winter or hotter external temperatures in the summer can make the unit work harder and longer, which can increase the amount of power it uses.\r\n\r\n \r\n

Average wattage use of MRCOOL mini splits<\/strong><\/h2>\r\n \r\n\r\nHere are the typical wattage ranges for MRCOOL mini splits by BTU capacity:\r\n\r\n \r\n\r\n9,000 BTUs = 800-900 watts\r\n\r\n \r\n\r\n12,000 BTUs = 1,000-1,200 watts\r\n\r\n \r\n\r\n18,000 BTUs = 1,500-1,800 watts\r\n\r\n \r\n\r\n24,000 BTUs = 2,000-2,400 watts\r\n\r\n \r\n\r\nHere are the amperage draws:<\/strong>\r\n\r\n \r\n\r\n9,000 BTUs = 7-8 amps\r\n\r\n \r\n\r\n12,000 BTUs = 8-10 amps\r\n\r\n \r\n\r\n18,000 BTUs = 12-15 amps\r\n\r\n \r\n\r\n24,000 BTUs = 16-20 amps\r\n\r\n \r\n\r\nFor example, if you find out that an 18,000 BTU MRCOOL mini split unit runs at about 1,500-1,800 watts and pulls 12-15 amps, you\u2019ll get a sense of what type of circuit it needs to work the best in your space.\r\n\r\n \r\n

Mini split power use vs. other heating & cooling systems<\/strong><\/h2>\r\n \r\n\r\nCompared to other types of cooling and heating equipment, MRCOOL mini splits are relatively energy efficient for their capacity, considering that:\r\n\r\n \r\n
