The term FCU HVAC stands for Fan Coil Unit Heating, Ventilation, and Air Conditioning. It is a type of HVAC system that is used to provide heating and cooling in a variety of different settings. FCU HVACHVAC systems are often used in commercial buildings, such as offices, schools, and hospitals, as well as in residential homes. The system works by using a fan coil unit to draw in air from outside, heat or cool it, and then distribute it throughout the building. The fan coil unit is typically connected to a thermostat, which allows the user to adjust the temperature to their desired level. FCU HVACHVAC systems are highly efficient and cost-effective, making them a popular choice for many different types of buildings. Additionally, they are relatively easy to install and maintain, making them a great option for those looking to save money on their energy bills.
