Here at Texas Made Air Conditioning and Heating in Granbury Texas we like to educate our customers on different parts of their heating and cooling system so they understand all the different components that help keep them cool and warm. Let’s take a look at what a fan coil does within your HVAC system.
First of all, the term fan coil unit, will mean different things to different people in regards to output capability and size. However the two main types of fan coils are categorized as ones that draw through and ones that are blow through (the heat exchanger). Draw through units are more expensive, but considered to be a better product.
Fan coils will be found in residential and commercial buildings that have a HVAC system in place. Depending on the building and the system, the fan coil unit may be exposed or concealed. It is a device that helps control the temperature where it is installed, sometimes using ductwork, and is controlled by a thermostat or an on and off switch.
The coil works by receiving hot or cold water and then either adds or removes heat through a process known as heat transfer. The fan coil then circulates cold or hot water through a coil to provide either heating or cooling to a space. The fan coil also has the ability to dehumidify the air, therefore a condensate will develop and this is taken to a drain, this is why the fan coil unit has a drip tray.
Texas Made Air Conditioning and Heating hopes this blog has clarified the role of the fan coil, and you can understand how important it is to make your HVAC system work efficiently. Fan coils should be kept clean and during a yearly checkup, your HVAC technician will examine them to make sure they are in good working order.
