Texas Made Air Conditioning and Heating Fan Coils for Heating & Cooling Systems

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.


Texas Made Air Conditioning Problems

In Granbury Texas, Texas Made can assist you with any problems your air conditioner experiences. Our trained technicians are on call to diagnose issues and present you with solutions. Some of the most common problems that your HVAC system can encounter are as follows. Low refrigerant can mean your air conditioner needs to be recharged which in turn can imply a leak or a larger problem within your refrigerant system. Low refrigerant can even cause your coils to freeze.

It is important to have a leak located and repaired. Refrigerant is a chemical best handled by your air conditioning specialist. If you have an older HVAC system, faulty wiring that has become loose and frayed can become a fire hazard, trip your circuit breaker and even stop the system receiving power. If your system is newer, but it wasn’t installed properly or by a trained professional, the wiring may not have been hooked up correctly.

If the outside component is experiencing trouble it may not be receiving power, or it could be associated with a thermostat that isn’t working correctly. Another common problem is an outside fan malfunctioning, the fan moves the heat from your residence to the outside. If the fan isn’t working, the air conditioning compressor can overheat and this in turn will trip the safety overload. Be sure to always keep debris away from the outside unit, clean up all leaves, grass and dirt surrounding it at least once a month. Last of all, be sure to replace your filters so return air ductwork doesn’t become obstructed with dirt.
