A 5 ton AC package unit is a self-contained air conditioning system that is used to cool large spaces such as commercial buildings, warehouses, and other large areas. The package unit contains all the components necessary for air conditioning, including the compressor, condenser, evaporator, and other components. It is designed to be installed outdoors and is connected to the building’s ductwork. The package unit is typically rated in tons, which is a measure of the amount of cooling it can provide. A 5 ton package unit is capable of cooling up to 5 tons of air per hour, which is enough to cool a large space. Package units are usually more efficient than split systems, as they don’t require separate components to be installed. They are also easier to install and maintain, making them a popular choice for commercial and industrial applications.
