How to Clean a Window AC Unit

Now, let’s get down and dirty and start cleaning the window air conditioning unit. The best part about this process is that you won’t even have to remove the unit while cleaning it. And you can do so, just by using the tools and cleaning products that are lying around in your house.

Here are the steps that you need to follow:

1. Switch off the air conditioning unit

You need to first turn the AC unit off and then disconnect the unit from the electrical power source. This is necessary because if you don’t do this, you might be at risk of being electrocuted in the process.

2. Remove the grill on the front

Next, you have to carefully remove the grill from the front of the AC. This will provide you access to the coils and filters. If the grill is not screwed-in, then you can remove it just by pulling it downwards.

On the other hand, if it is screwed-in, then you have to use the screwdriver.

3. Remove the filter of the AC unit

The next step is to take the filter and carefully remove it from the air conditioner. Make sure that the air filter doesn’t have any dents or leaks in it.

If your air conditioner has a disposable air filter and it’s showing signs of build-up and molds, then you should just replace the filter.

In contrast, if your filter is reusable, you can simply clean the filter and make it as good as new again. You can use a sponge and dishwasher soap while cleaning the air filter. If you find it hard to get the stubborn molds out of the air filter, then we suggest you leave the filter submerged in warm water for 30 minutes before cleaning.
