A 4 ton HVAC package unit is a type of heating, ventilation, and air conditioning (HVAC) system that is typically used in commercial buildings. It is a self-contained unit that combines all of the components of a traditional HVAC system into one unit. This includes the compressor, condenser, evaporator, blower, and other components. It is designed to be a single, easy-to-install unit that can be placed on the roof or outside of the building. The 4 ton designation refers to the amount of cooling capacity the unit is capable of providing. This is usually measured in British Thermal Units (BTUs) and is typically enough to cool an area of approximately 1,000 to 1,500 square feet. The 4 ton package unit is a great option for businesses that need to cool a large area but don’t have the space or budget for a traditional HVAC system. It is also a great option for businesses that need to cool multiple rooms or areas of the building.
