Furnace Coil 101: What can go wrong with your heating system?

Most of the homeowners in the U.S. have a split system that has been designed to perform both the heating as well as cooling services. These systems house something that isn’t ordinarily found in the furnaces, the Furnace Coil.

So, what exactly is a furnace coil? How does it function?

In this article, we will essentially explore this ignored part of the heating/cooling system and understand why it matters. But, before we get deep into it, keep in mind that nothing would go well with your system unless you opt for regular heating maintenance, Fort Worth, TX. Well-scheduled maintenance sessions ensure that the machine functions at its optimum without any possible glitch.

What exactly makes up for a furnace coil?

Also known as the “Evaporator Coil” or the “A Coil,” given their unique triangular shape, this particular furnace part plays a critical role in the split system. Both heat pumps and air conditioners work by carrying the heat present in one location and releasing it in another. During the summer months, both these systems take in the heat present inside your house and move it away from the premises towards the outside.

The entire thing is accomplished with the help of a refrigerant. This happens as the refrigerant present in your HVAC system moves through its evaporator coil and hence absorbs the heat. This refrigerant then passes to the outside area where this unwanted heat is evicted. This is a continuous cycle as long as your system is on.

However, the heat pumps tend to reverse this operation during the winter months. They tend to pull the heat energy present in the outdoor air and bring it inside while expelling the cold air present outside. In case your heat pump fails to do this job and the interiors are feeling way too cold, make sure you schedule a session for heating maintenance, Fort Worth, TX. This ensures that any need for repairs can be taken care of immediately to restore the machine’s functionality.

Why is there an evaporator coil within the furnace?

During the winters, while your furnace tends to use electricity or gas for heat generation, the coil present inside acts as a medium for heat exchange. It absorbs the heat to ensure that your blower can easily distribute the same through the air ducts.

Why should you clean the furnace coil?

Furnace coils aren’t just present inside your furnace assembly; it can also be in its very own casing. Most of the issues related to the furnace coil tend to surface from the fact that it isn’t maintained on a regular basis with regards to the cleaning and repair needs.

Dirt and dust build-up in your system can lead to a plethora of issues. Furnace coils loaded with dirt isn’t good with regards to heat energy transfer. With time, you will notice that the energy efficiency of your system is depleting at a staggering level.

2-Mildew and Mold:

When your air conditioning system or the heat pump is being used during summer months, the intermixing of cold and hot in the same space can lead to mold & mildew growth.
