Blog written by Veva.

Clean air is a core part of human health and happiness. Wouldn't you agree? We must have clean, breathable air to survive. Unfortunately, indoor air quality or dirty air can cause various health issues, including asthma, allergies, coughs, and dandruff. An improperly functioning window air conditioner unit can also harm your family by creating an unhealthy environment. 

For that reason, we've dedicated this comprehensive blog to enlighten you about how to clean your window air conditioner. But first, let's understand the importance of cleaning your window AC unit and when you should do it.

Why Clean Your Window AC Unit?

Here are the top four reasons why cleaning your air conditioning system should be a household routine:

Cleaning your air conditioner helps keep your family safe and healthy.

Regular cleaning prevents dust, debris, pollen, smoke, bacteria, mold spores, and other pollutants from entering your unit. Thus, it can keep everyone inside safe and healthy. Even more amazingly, washing and drying the unit before storing it ensures that everything gets off safely after its use. 

Regular cleaning can prevent expensive damages caused by a malfunctioning unit.

When dirt collects within the unit, the fan blades can get clogged with them. As a result, these blades won't rotate efficiently, no matter how much energy they need to work. Also, if the fan motor gets damaged, it could overheat or lead to overheating of the entire unit. In both cases, a broken-down conditioner may release toxic gases, fumes, and smoke that can compromise health when inhaled.

Improved airflow through the system helps maintain proper temperature control.

There are numerous ways in which dust, dirt, pollen, and other substances can affect the performance of window AC units. First, they could block up the air purifier filter media; secondly, they might block off the venturi effect, making temperature adjustments tricky. Thirdly, they could alter the airflow pattern and eventually reduce the effectiveness of the unit itself. If any unit components get blocked or damaged, this may worsen the situation drastically, as well.

A clean AC unit provides reliable service every time.

Allowing dirty air filters to fill up with dirt makes it difficult for the unit to capture fine particles suspended in the air. As a result, dirt accumulates on the surface of the condenser coil. Therefore, more electricity has to go into running the fan and blower motors than usual. The more the fan works, the higher the chances that it will burn out. Besides, if any part of the unit is not wiped out, it will attract excessive moisture, leading to corrosion and rusting.

When Should You Clean Your Window AC Unit?

There's no doubt that cleaning your home's window AC unit is a worthwhile health and hygiene measurement. But knowing when to do it is equally important. So, if you notice any of these symptoms, that's a sign that it's time to clean your window AC unit:

  • Your child is always complaining of having colds
  • You and your family members are frequently suffering from hayfever or allergy problem
  • Dry cough usually happens after waking up or during sleeping hours
  • Your baby's hair gets tangled due to excessive dust accumulation on the fan blades
  • Your baby is suffering from rashes and hives
  • Your child sneezes all the time while playing with toys or while going out of the house
  • Your windows get fogging problem after using the air conditioning system
  • A strange odor emanates from the vents
  • The cooling effect is not as effective as expected

How to Clean Your Window AC Unit

All along, we've been discussing the benefits of cleaning your AC unit and when to do it. Now it's time to take a deeper dive into the most crucial section: how to do it! Here's a simple step-by-step guide:

1. Remove the cap.

The first step is easy – all you have to do is unscrew the top of the unit. You should never try to remove this panel without first removing the entire filter assembly. Once the cap comes off, you can give it a good scrubbing.

2. Wipe down the filter.

Keeping the air filter clean is important because it protects it from being clogged by water or dust. Dust accumulation reduces the efficiency of the filtration system. As a result, you may notice an increase in temperature in the room. Furthermore, if the unit gets too warm, it could start blowing cold air. This is why keeping the AC clean at all times is essential.

3. Remove debris from the coils.

Cleaning the coils is also very important. Some of the most common items that collect here include hairspray residue, paint flakes, hair, clothing fibers, lint, dog or cat fur, chewing gum, food crumbs, etc. When cleaning coils, make sure to use a vacuum cleaner. Also, be careful when using any abrasive material since the unit's metal parts could be scratched.

4. Use compressed air to blow away dust.

Compressed air can be used to clean up any loose debris. However, always remember that cleaning out the vents with air is highly recommended. This way, you prevent dust accumulation in the vents themselves and keep them free from mold and mildew.

5. Do a final check.

After cleaning everything, perform a quick inspection to ensure that no damage was done to the unit itself. If there's nothing wrong with it, then feel free to replace the filter. Otherwise, continue reading below to learn what you need to know about replacing your AC filter.

6. Replace the Filter.

It's crucial to note that sometimes you won't find a new filter inside the package. In such cases, don't panic – just replace the old one with a new one.

7. Reapply the Cap.

When installing a new filter, make sure to reattach the cap after putting it back onto the unit. Without a proper seal, contaminated air might seep through and cause the coils to get dirty again.

8. Run a test.

Before operating your window AC for the first time after cleaning it, run a test to determine if the filter works properly. To do so, simply turn on your unit and see if the airflow blows out evenly throughout the house.
