Below is a list of Cabinet Air Conditioner manufacturers from Elmira, New York. A cabinet air conditioner removes heat from the air in a given space through use of components that are contained in a boxlike enclosure. The enclosure is typically made from metal such as stainless steel or aluminum and contains a compressor, a condenser, an expansion valve, a thermostat and a series of motorized fans. The unit is generally attached to a system of air ducts or air handling equipment that delivers the cool air throughout a building.
