The term “carrier 10 ton package unit” is used to describe a complete HVAC system that is self-contained and ready for installation. This type of unit is typically used in commercial and industrial applications and is designed to provide efficient heating and cooling solutions. It is composed of several components, including an air handler, condenser, evaporator, compressor, and other components. The air handler is responsible for circulating air through the system, while the condenser and evaporator are responsible for cooling and heating the air. The compressor is responsible for pressurizing the refrigerant, which is then used to transfer heat between the indoor and outdoor environment. The package unit is also equipped with an insulation layer that helps to reduce energy costs. The unit is designed to provide a wide range of cooling and heating solutions, with an efficiency rating of up to 10 tons. It is also designed to be reliable and durable, making it a great choice for commercial and industrial applications.
