Did you know that lack of cleaning is one of the main causes of bad odor, poor performance, and increased energy consumption in window air conditioners?
The good news is that you don't need to disassemble the entire unit to perform an efficient cleaning.
With a few simple precautions, it's possible to keep the equipment clean, functioning well, and producing healthier air. Let's go through the step-by-step process.
1. Unplug the unit
Before starting any cleaning, unplug the air conditioner.
This step is essential to avoid electric shocks and ensure complete safety during the process.
Never perform maintenance with the equipment plugged in.
2. Cleaning the exterior
With a soft, slightly damp cloth, clean the entire exterior of the unit, removing accumulated dust and dirt.
If necessary:
use a little neutral detergent,
avoid abrasive products or strong chemicals, which can damage the paint and finish.
This simple cleaning already greatly improves the appearance of the equipment.
3. Cleaning the air filters (most important part)
Air filters accumulate dust, mites, and other impurities, and when they are dirty, they impair the functioning of the appliance.
In most window models:
simply open the front grille,
carefully remove the filters.
How to clean correctly:
wash the filters under running water,
use neutral detergent,
let them dry completely in the shade before replacing them.
📌 With frequent use, it is ideal to do this cleaning every 15 days.
4. Cleaning the internal fins
Using a vacuum cleaner with a fine nozzle or a dry brush, gently clean the fins where the air comes out.
This care helps remove accumulated dust and improves airflow.
Do everything calmly so as not to bend the fins, which are sensitive.
5. Cleaning with Air Conditioner Spray
For a more thorough cleaning without disassembling the unit, use a specific air conditioner spray, readily available on the market.
These products help eliminate:
fungi,
bacteria,
unpleasant odors.
How to use correctly:
with the unit turned off, apply the spray to the air intakes and fins,
always follow the manufacturer's instructions,
wait the indicated time before turning it on again.
Conclusion
Keeping your window air conditioner clean is simpler than it seems.
With periodic cleaning and without disassembling everything, you guarantee:
✅ cleaner and healthier air
✅ elimination of bad odors
✅ lower energy consumption
✅ longer lifespan of the unit
For deeper cleaning and complete servicing, it is ideal to schedule technical maintenance at least once a year.
