Keep the Coils on Your AC Clean!

evaporator-coilIt’s getting late in the summer season, and before long we are going to be turning to our heaters, and not our air conditioners, in our efforts to live comfortably. That doesn’t mean that we’re out of the cooling season just yet, though, or that it is too late to impart some AC-related wisdom upon our readers. Today we want to talk about some very important components of the air conditioner — the coils — and why it is so important to keep them clean.

Routine air conditioning maintenance will ensure that your coils are clean at least once a year — and we strongly recommend that you explore the benefits of enrolling in our maintenance plan — but sometimes that just isn’t enough. You shouldn’t be disassembling your AC to clean any components on your own, but there are steps that you can take to help protect your air conditioner in Des Moines, IA. Read on to learn more about these coils, and how cleanliness affects them.

What Do These Coils Do?

The coils in your air conditioning system, both the indoor evaporator coil and the outdoor condenser coil, play a vital role in the cooling process. In case you are not familiar with the way in which your air conditioner really works to cool the air, you should know that it all comes down to the refrigerant cycle. Basically, the air conditioner evaporates refrigerant, drawing heat out of the air in your home, and then condenses that refrigerant in order to disperse that air outside. The evaporation of the refrigerant takes place in the evaporator coil, while the condensation of the refrigerant takes place — you guessed it — the condenser coil.

What Happens if These Coils Are Dirty?

If either the evaporator coil or the condenser coil are dirty, then your air conditioner is going to have a harder time of cooling your home than it should. If the evaporator coil is dirty, for instance, it is harder for the coil to draw heat out of the air passing over it. In fact, the coil could fail to draw sufficient heat to the point that it gets cold enough to freeze the condensation that has settled on it! When that happens, the layer of ice only further insulates the coil, making matters all the worse.

If the outdoor (condenser) coil is dirty, then the system is going to have trouble dispersing heat from the refrigerant. This is obviously problematic, as that heat must be released in order for the refrigerant to remove more from the air in your home. If the fins on the outdoor unit are clogged up or bent, your system is really going to be working harder than it should have to. This drives up energy costs, along with the risk of running into system damages.

You can help to protect the operation of your coils and the system as a whole by keeping a clean air filter in your air conditioner, as well as by keeping the outdoor unit free of debris such as fallen leaves and grass clippings. Routine maintenance will ensure that the system and the coils receive a  deep clean annually.
