The definition of RTU HVAC cost is the total cost associated with the installation and operation of a Heating, Ventilation, and Air Conditioning (HVAC) system that utilizes a Remote Terminal Unit (RTU). This cost includes the purchase of the RTU, the installation of the unit, and the ongoing maintenance and energy costs associated with the unit. The RTU HVAC cost is typically higher than the cost of a standard HVAC system due to the additional components and technology required for the RTU to function properly. The RTU HVAC cost can vary greatly depending on the size of the unit, the complexity of the installation, and the type of energy used to power the unit. Additionally, the RTU HVAC cost can be affected by the availability of local energy sources, the cost of energy in the area, and the cost of labor for installation and maintenance. Ultimately, the RTU HVAC cost is an important factor to consider when selecting an HVAC system for a home or business.
