There is a process to follow for how to clean your wall air conditioner without removing the entire unit from the wall.
Air conditioners work much more effectively and efficiently when they are properly cleaned and well-maintained.
If you want to keep your wall air conditioner clean, but you do want to avoid the additional effort of removing it from the wall every time you clean it, you can divide the cleaning process into parts that include cleaning the air filters, cleaning the coils, and cleaning the unit to remove mould and mildew.
Why it is important to keep your air conditioner clean
As convenient as air conditioning can be to cool you down on hot summer days, it can be just as frustrating when your air conditioner does not work the way it is supposed to when you need it most.
A key part of ensuring that your air conditioner is as effective and as energy-efficient as possible, is ensuring that the unit is well-maintained and clean.
How to clean a wall air conditioner without removing it
While your wall air conditioner may still be capable of cooling your room or your space when it has not been cleaned, it will not be able to function optimally.
Fortunately, you can keep your wall air conditioner clean even without the added time and effort that it takes to remove it from the wall entirely, by simply dividing the cleaning process into a few parts, as is outlined below follows:
| Cleaning process | Description |
| Part 1 | First clean the air filters to ensure good airflow to the rest of the air conditioner. This should be done regularly. |
| Part 2 | Secondly, you can also clean the coils behind the air filters to remove any dirt and debris that may have built up over time. You only need to do this if you notice any dirt on the coils. |
| Part 3 | Lastly, you need to remove the entire front cover of your air conditioner to get rid of any mould or mildew. This only needs to be done if you notice a musty smell or any other signs of mould. |
Each of these parts can be explained in more detail to help you to keep your wall air conditioner clean and functioning as effectively and efficiently as possible.
How to clean the air filters on your wall air conditioner without removing it
The air filters of your wall air conditioner are designed so that they can be removed easily to clean them, without removing the entire unit from your wall.
In most cases, your wall air conditioner will have a front flap that can open, from which you can remove the unit’s air filters.
Since these air filters are designed to trap any dirt or debris in your air before it can reach the rest of your air conditioner, they tend to get a build-up on the surface over time, which can block the airflow to your unit.
To remove any dirt or particles that may be in this filter and to clean it, you can use your vacuum to just clean the surface, or you can even scrub the filters carefully in some lukewarm water with a soft brush and a gentle detergent.
You need to let the filters dry completely before you can place them back in the air conditioner.
How to clean the coils on your wall air conditioner without removing it
If you start noticing that some of the dirt and debris has gotten through the air filters and has started building up on the coils behind this filter, you can also clean this component without removing the entire air conditioner from the wall.
All you need to do is to remove the air filters as you normally do to clean them, and then use a toothbrush or gentle scrubbing brush and a diluted distilled white vinegar solution in a spray bottle or a coil cleaner to scrub the coils gently.

How to clean your wall air conditioner to get rid of mould and mildew
If you notice a musty smell or any signs of mould or mildew growth coming from your wall air conditioner, you may need to do a more thorough cleaning. Fortunately, this can also be done without removing the air conditioner from the wall entirely.
To do this, you will need to unscrew the front cover of your unit, and then thoroughly scrub the coils and the sides of the unit with a mould and mildew remover, which can then be rinsed off a few minutes later with water.
