A 5 ton rooftop unit is a type of air conditioning system designed for commercial buildings. It is a self-contained unit that is installed on the roof of a building and is used to provide cooling and heating to the interior of the building. The unit consists of a compressor, condenser, evaporator, and other components. The compressor compresses the refrigerant gas and circulates it through the system. The condenser then releases the heat from the refrigerant gas and the evaporator absorbs the heat and transfers it to the air inside the building. The 5 ton rooftop unit is an efficient and cost-effective way to provide cooling and heating to a large commercial building. It is also relatively easy to install and maintain, making it a popular choice for many businesses.
