AC Component Guide: The Evaporator Coil

Here at Goettl Air Conditioning, we believe that an informed homeowner is a wise homeowner. You should never attempt to service your home cooling system on your own, even if you do your reading and watch an internet tutorial video marathon. That being said, you should have some idea of how the systems that you rely upon in your home actually function. 

One component in your air conditioning system that you may have heard of is the evaporator coil. While you may know the name, you may not understand exactly what this (very important) component actually does. Read on to learn a bit more about how your evaporator coil facilitates the cooling process.

What Does the Evaporator Coil Do?

The evaporator coil resides in your indoor air conditioning unit, and it serves a vital purpose in the operation of the AC at large. It’s one and only function is to get the heat transfer process underway, which it does via the evaporation of refrigerant. Refrigerant is the heat transfer fluid in your AC, and it absorbs heat as it evaporates. Remember, your AC does not generate cool air; it removes heat from the air that is already in your home. As hot air passes over the evaporator coil, its heat is drawn out by evaporating refrigerant. Essentially, this coil functions as the air conditioner’s heat exchanger.

The Coil Must Be Kept Clean

If your evaporator coil encounters operational problems, you are going to struggle in cooling your home. One of the best things that you can do for your AC is simply ensuring that the coil is kept clean. Your AC technicians will clean the coil during routine maintenance. If dust and dirt are allowed to build up on the coil, the heat transfer process can be compromised, putting a lot of strain on your AC, driving up cooling costs even as cooling output drops.

My technician Jorge (George) Gutierrez was out today performing the a/c system check. He did a fabulous job and identified significant issues and concerns for the longevity of my current 12 year old system. He was very knowledgeable and helpful on what my options are and in the end I’ll be getting a new system instead of worrying about the current system failing in our extremely hot temperatures. He was very respectful of my home and my dog was ecstatic to meet him.

Frank identified the need for new faucets in the master bath and discussed my preferences. The type of faucet being replaced is no longer available (mini wide spread) so he had to do some research to come up with a solution. Had to be ordered, not surprisingly, and we appreciate his conscientious performance.

This was my first service with this company and it was a pleasant one. The technicians were professional and polite and quickly resolved a minor scheduling conflict. Interaction with a sales manager for a quote on needed equipment was equally pleasant.

Signed up for the Sadie membership as a a preventative measure to avoid bigger problems down the line. Had my appointment to check my system today and to my surprise the tech discovered a huge gash in my ductwork! Thankfully so because the ductwork up there is a very tight space which I could never squeeze myself into and would’ve gone unnoticed for who knows how long. Huge thank you to Technician Roy Adame for making the trip out on a Saturday afternoon, going the extra mile to fully inspect the system in a tight space, and fully explaining the possible causes of the damage and the impact it would on the system performance. 🙏🏼🤙🏼🫡👏🏼🙂
