HVAC fan coil units are a type of heating and cooling system used in many residential and commercial buildings. They are designed to provide efficient, cost-effective climate control by using a fan to circulate air through a coil that is either heated or cooled. The fan coil unit is connected to a central air conditioning system, and the fan draws air from the room, passes it through the coil, and then returns it to the room. This process helps to regulate the temperature of the room and maintain a comfortable environment. The fan coil unit also helps to reduce energy costs by allowing the user to control the speed of the fan, which can be adjusted to meet the needs of the space. HVAC fan coil units are a great choice for those looking for an efficient and cost-effective way to keep their space comfortable.
