What is Central Air Conditioner Evaporator?

Did your local HVAC professional mention your central air conditioner evaporator and you’ve no idea what it is? In a nutshell, it’s actually what cools the air before it is blown into your room. A lot of homeowners can’t locate it easily because it’s enclosed in a metal case, looking like a bulk of copper coils that sits inside your unit.

Are you still confused? Here’s what you should know about AC evaporator coils.

The Basics

If you ever think that your AC primarily creates cool air on its own, think again. It’s not how it really works. Your unit removes heat from the indoor air. This is where your evaporator coils become handy.

Your AC’s evaporator coils have a refrigerant that absorbs moisture and heat from the indoor air. Then, it gets converted into cool, dehumidified air that gets released inside your home.

After that, the heat and moisture are carried all the way to the condenser, dumping it into the outdoor air.

AC Evaporator Maintenance

Now that you know how the process works, it’s time for aftercare. Your AC evaporator needs to be maintained, too. Otherwise, you might deal with further problems that won’t only affect your evaporator but also the whole unit. Here are three maintenance tips you can do at home.

Replace Your Filter

Checking your filter once a month is highly recommended. And if you’re using your central air conditioner more often, especially during the summer months, it’s time to change it.

Keep the Vents Open

Make sure that all the air vents in your home remain open. What happens is that the blocked ones will restrict airflow in your AC system, causing a lack of warm air. This will eventually keep the cold coils frosted which aren’t good for your AC system. Warm air is necessary for your unit to function properly.

Keep Your Evaporator Clean

Your central air conditioner evaporator should remain clean. Dust and dirt can affect the heat transfer process. When left unattended, you’ll notice that your AC is no longer cool enough, your energy bill increases, there’s more wear and tear on the unit, and ice builds up on the coils.

Cleaning them should solve and even avoid these problems. Access the evaporator on the indoor unit. Wipe all the dust, dirt, and other debris with a soft brush or cloth. You may also use a commercial cleaner to speed up the process. If there is larger debris to get rid of, you can use compressed air.

Opt for Maintenance

Preventive maintenance is an essential part of your central AC aftercare. Your HVAC professional does it. Once you call them, they will come over to your home and replace the air filter if necessary, check your evaporator, spot some potential issues like refrigerant leaks and fix them before they turn out to be bigger problems.

Key Takeaway: Central AC Maintenance

Maintenance is a great investment that will increase your central AC’s lifespan. Aside from cleaning your unit, this will also help you diagnose problems that might cost you a lot more money later on.
