The Importance of a Clean AC Evaporator Coil


Your air conditioner works day in and day out, but some parts put in more work than others. Your evaporator coil is one of them.

Without the evaporator coil, you wouldn’t be able to remove heat from your home in the first place. It’s one of the last parts that you want to have to replace or repair, which is why air conditioning maintenance in Casselberry, FL is so important.

Your coil is built to last, but when it gets dirty, it tenses up and problems begin to emerge. This is why it’s important to keep it as clean as possible.

Less Chance of Freezing Up

A dirty coil leads to freezing. When your coil is dirty, the airflow that’s supposed to roll over the coil isn’t as effective. Dust covers it and acts as an insulator, blocking any temperature change from the airflow.

Your evaporator coil can still freeze up if you put your AC settings too low and run it continuously, so don’t think that a clean coil is the only way to prevent it from freezing. If you keep your fan on auto and don’t set your temperature too low, you’ll be fine.

But a dirty coil can cause freezing even at higher temperatures. Make sure you’re changing out your air filters and ensuring that the drainage line is clear as well to cover your bases.

Better Long-Term Efficiency

A clean coil ensures good airflow, which means your coil can do its job as quickly as possible. When dust insulates your coil even a little bit, your efficiency drops.

Think about it on a larger scale: your coil is dirty, so it takes longer to extract heat from your home. That means the AC is on for longer, which costs more money to run, and puts more wear and tear hours on each component. The money adds up quickly in terms of monthly bills and repair costs over time.

Reduced Risk of Complete Air Conditioner Breakdowns

You have annual maintenance appointments for your AC, but that doesn’t mean that you’ll never experience a breakdown ever again. Your AC will need repairs at some point, whether you live in Casselberry or not.

By keeping your coil clean and shortening the amount of time each cycle takes, you’re effectively reducing the wear and tear on your air conditioner as a whole. This effect ripples and lowers the strain on multiple components in your air conditioner.

Your Evaporator Coil Needs Some TLC

Remove the dust, clean it off, and enjoy better efficiency without worrying about your coil breaking down on you. It’s a pretty wild list of benefits to come from a basic task like cleaning.

Annual maintenance appointments should be enough to handle dust buildup and dirt on your evaporator coil. If not, you can always clean it off in between each maintenance appointment. It’s up to you, but don’t underestimate the importance of a clean coil.
