    DC Inverter Air Conditioners are the ultimate cooling and heating technology of the HVAC field.  They are called "DC inverter" because the alternative current (AC) is converted to Direct Current (DC) then, direct current inverted back to Alternative current with desired frequency. As known, the current supplied through the wall outlet has fixed frequency which is 60 Hertz. Different frequencies supplied to the compressor will result different running speeds of the compressor.  YMGI Inverter control systems use Pulse Amplitude Modulation (PAM) that is the most advanced and energy efficient method of inverting the current.  DC Inverter air conditioners bear special compressors that their speed could be changed by increasing or decreasing the frequency of the supplied power.  Therefore, unlike conventional split Air Contioners/Heat Pumps which cycle between on and off repeatedly, the DC Inverter control system will monitor the room temperature and adjust the compressor speed automatically.

    Conventional compressors turn on and off to maintain the room temperature at desired level.  This will result compressor to draw tremendous energy each time it starts up. This will also reduce the life-span of the compressor and other components that are turning on and off.  Once a conventional system is running, it runs at its maximum speed, consuming the maximum amount of energy in order to produce the maximum of cooling or heating to maintain the desired temperature.  The system will then cycle between on and off in an effort to maintain this temperature. When a DC Inverter compressor initially starts up, it runs with a higher speed to bring the room temperature to desired level rapidly. Once the set temperature is reached, it slows down and adjust its capacity to counter the heat loss or heat gain of the building. By this way it will maintain a constant temperature.

    Installation Overview back to the top
    BASIC OVERVIEW:  The indoor unit is hung like a picture frame approximately 6 - 8 feet above the floor usually on an exterior wall.  A 2-3 inch hole must be made behind the indoor unit in the exterior wall to run the refrigerant copper tubing, electrical wires and the condensate drain to the outside unit. The indoor unit and outdoor unit are connected to each other by means of refrigerant copper tubing and electrical cables.  The condensing unit comes pre-charged with Freon however, the lines still need to be vacuumed to evacuate the excess Nitrogen prior to the final coupling for operation.  Click to Download Installation Manual. *Although the installation may seem easy to some, certain tools and experience is necessary to complete installation of a mini split*  See Installation Tip.  A certified HVAC technician must conduct / complete the installation to be eligible for the warranty.  (See warranty details below > ) Installation Kit

    *5 Year Compressor - 1 Year on all other Parts*  Registration card will be sent with unit, this card should be completed by an HVAC technician (installer).  Installation of a mini split must be completed by a licensed HVAC (Heating, ventilating, & air conditioning) company to ensure any issues encountered in the future are not due to improper installation / workmanship.  Even though mini split setup is below the expertise requirements of central AC systems, these are not "plug-n-play" units that can be properly installed without certain tools any prior HVAC - electrical knowledge.   The installation includes electrical, gas, and refrigerant connections and generally regulated by a multiple sets of laws, codes and guidelines, at the federal, state and local levels. The failure to properly install HVAC equipment can raise personal safety and performance concerns. Warranty service - troubleshooting is provided through the contractor / installer and will be upheld as long as policies are observed.  Once a non-defective unit is installed by a HVAC company, chances of anything going wrong are very slim and almost all contractors will guarantee there workmanship and provide future service free of charge (installation warranty).  If it was determined that the unit is not functioning due to a defect and needs to be replaced, the part will be sent free of charge up to 1 year from date of purchase or 5 years for the compressor. If you receive a damaged or defective product, a replacement unit will be sent out Free of cost.  Damaged / Defective product will be picked up and brand new exchange will be shipped out.
