Ductless Split Air Conditioners (also known as ‘mini splits’) are mainly used in residential or commercial buildings without built in ducting system. Mini Split is often referred to as SPLIT CONFIGURATION. The compressor and evaporator are in separate external packages and the two
units connect via refrigerant pipes.
Between the indoor and outdoor units of the mini split air conditioners, there is a set of electrical wires & two insulated copper tubes for the R410-a refrigerant gases. They run through between the indoor and outdoor units. This eliminates the need for ductwork instead all you need is a 3- inch hole in the wall to run your wires and tubes through. All of our Shinco units are pre-charged with the highly efficient, environment friendly R410-a refrigerant. The Shinco Mini Split Air Conditioners are powered from the outdoor unit. The indoor air handler is mounted on the wall high up near the ceiling. The temperature is controlled by means of a remote controller and you can set the unit to cool, heat or dehumidify at a perfectly precise temperature.
Shinco units require minimal maintenance. Bellow you will find two recommended tasks:

The Inverter Technology offers the ability of the unit to continuously provide thermal air passage by altering the speed of the compressor in either cooling or heating modes. SHINCO Inverter Technology is advanced & intelligent. In turn, SHINCO units draw 40% less electricity!
Seasonal Energy Efficiency Ratio (SEER) is a unit of measurement for cooling and heating output.
British Thermal Unit (BTU) is a unit of measurement that determines how much cold/hot air comes out of each unit. The more air comes out, the more space it needs for the air to circulate. If the unit is oversized it may cause problems such as sensors reading false temperatures. Refer to the table below for more information:
| Sq. Ft. | Sq. M. | BTU |
|---|---|---|
| 150 | 14 | 5,000 |
| 350 | 33 | 8,000 |
| 425 | 39 | 9,000 |
| 500 | 46 | 10,000 |
