In this post, we will discuss four practical techniques to clean a window air conditioner, assuring its durability and functionality. 

Whether you’re a homeowner or a renter, these cleaning procedures are straightforward, cost-effective, and may be readily completed without professional help.

Why Clean Your Window AC Regularly?

Regular maintenance of your window air conditioner gives various advantages. Firstly, it improves the air quality within your house by eliminating dust, grime, and allergens trapped in the unit. 

Secondly, a clean air conditioner performs more effectively, resulting in decreased energy usage and reduced electricity expenses. Additionally, appropriate maintenance helps increase the lifetime of the device, saving you money in the long run. 

By following these cleaning procedures, you can guarantee that your window AC stays in excellent condition.


Supplies Needed For Cleaning

Before we go into the cleaning procedures, it’s crucial to obtain the appropriate materials.

Here’s a list of stuff you’ll need:

  • Screwdriver Vacuum cleaner with brush attachment
  • Mild detergent or vinegar
  • Soft cloth or sponge
  • Water spray bottle
  • Fin comb (optional)
  • Fin brush (optional)

Method 1: Cleaning The Filter

The filter of your window air conditioner performs a critical function in capturing airborne particles and preserving acceptable air quality. Over time, the filter gets clogged with dirt and debris, preventing appropriate airflow. Follow these methods to clean the filter effectively:

  • Turn off and disconnect the air conditioner.
  • Locate the filter panel on the front or side of the machine.
  • Remove the filter panel by unscrewing or sliding it out.
  • Take off the filter and carefully vacuum both sides to remove loose debris.
  • For obstinate filth, wash the filter with a mild detergent or vinegar solution.
  • Rinse the filter with clean water and allow it to air dry entirely.
  • Once dry, reinstall the filter and fasten the filter panel.
  • Regularly cleaning the filter every 1-2 months will provide excellent air conditioning performance and preserve acceptable indoor air quality.

Method 2: Cleaning The Condenser Coils

The condenser coils are responsible for expelling heat from the air conditioners. Over time, these coils acquire dirt and debris, hampering the cooling process. Cleaning the condenser coils will increase the unit’s efficiency. 

Here’s how to do it:

  • Turn off and disconnect the air conditioner.
  • Remove the outer cover of the device by unscrewing or lifting it.
  • Locate the condenser coils towards the rear of the device.
  • Gently vacuum the coils using a brush attachment to remove loose debris.
  • For tough filth, use a soft cloth or sponge wet with a mild detergent or vinegar solution.
  • Wipe the coils gently, avoiding undue pressure or bending.
  • After cleaning, let the coils dry fully.
  • Reattach the outer cover and secure it in place.
  • Cleaning the condenser coils at least once a year helps increase the cooling effectiveness and extend the lifetime of your window air conditioner.

Method 3: Cleaning The Drainage System

The drainage system of your window air conditioner drains condensate water created during the cooling operation. Over time, algae, mildew, and debris may plug the drainage passages, resulting in water loss and diminished performance. 

Follow these methods to clean the drainage system effectively:

  • Turn off and disconnect the air conditioner.
  • Locate the drainage hole or channel at the rear of the unit.
  • Gently put a tiny brush or pipe cleaner into the opening to loosen any obstructions.
  • Mix a mix of equal parts water and vinegar.
  • Pour the vinegar solution into the drainage hole and let it settle for 10-15 minutes.
  • Flush the drainage system with clean water using a spray bottle.
  • Wipe away any residual wetness with a soft cloth.
  • Plug in the air conditioner and turn it on to check for good drainage.
  • Regularly cleaning the drainage system every 2-3 months can avoid water leaking and preserve the best functioning of your window AC.

Method 4: Cleaning The Exterior

While cleaning the interior components is necessary, it’s also essential to maintain the outside of your window air conditioner clean. Dust, filth, and debris may collect on the unit’s surface, impacting its overall look and performance. 

Follow these procedures to clean the outside effectively:

  • Turn off and disconnect the air conditioner.
  • Remove the outer cover by unscrewing or lifting it.
  • Wipe the outer surface with a soft cloth or sponge moistened with mild detergent or vinegar solution.
  • Pay specific attention to corners, crevices, and vents.
  • Rinse the cloth or sponge and remove any residue.
  • Wipe the outer surface again with clean water to eliminate soap or vinegar residue.
  • Dry the surface with a gentle towel.
  • Reattach the outer cover and secure it in place.
  • Regularly cleaning the outside of your window air conditioner will keep it appearing clean and well-maintained, boosting its overall effectiveness.
