A 120 volt mini split is a type of air conditioning system that is designed to provide efficient cooling and heating to a single room or area of a home. It is a great option for those who want to cool or heat a single room without having to install a full-sized air conditioning system. This type of system is usually composed of two parts: an outdoor condenser unit and an indoor air handler. The outdoor condenser unit is responsible for cooling the air and transferring it to the indoor air handler, which then distributes the cooled air throughout the room. The indoor air handler also has a fan that helps to circulate the air. The advantage of a 120 volt mini split is that it is energy efficient and can save you money on your energy bills. Additionally, it is relatively easy to install and can be done by a professional or by the homeowner.
