Now that you have gathered all the necessary tools and materials, it’s time to start cleaning your window-type aircon. This section will provide a step-by-step guide on cleaning window-type aircon effectively.

We will cover everything from preparing your aircon for cleaning to a more thorough cleaning of the coils and exterior. You should carefully follow the instructions to clean your aircon thoroughly and safely.

Step 1: Preparing to Clean Your Window Air Conditioner

  • Power Off the Aircon

Unplug the aircon unit or shut off the circuit breaker. Disconnect all power sources, including remote controllers, to prevent electric shock or damage to the air conditioning unit.

  • Remove the Unit’s Front Cover

Detach the front cover from the unit according to the manufacturer’s instructions – often, just unsnapping or unscrewing a couple of parts is enough. Set it aside for cleaning.

  • Cover the area around the aircon with a plastic sheet or cloth to catch any debris.

Step 2: Cleaning the Filter

  • Remove the AC Filters

Gently remove the filters from the front panel of the unit. These are usually located directly behind the front cover. Check the user manual to locate it accurately.

  • Vacuum Filters and Grilles

Use a vacuum cleaner with a soft brush attachment to clean dirt and dust gently but effectively from air filters, grilles, and louvers. Vacuum both sides of the filters, ensuring not damage or puncture them.

  • Wash Filters

In a solution of warm water and mild detergent, wash filters to remove any stubborn dirt and debris. The cleaning solution we usually use is hydrogen peroxide. Fill a basin or container with enough hydrogen peroxide solution, around 3%, so that you can submerge the filter completely.

Immerse the filters entirely in the solution and let them soak for between 15 and 30 minutes. This soaking allows the hydrogen peroxide to break down any bacteria, mold, or dust build-up on the filters.

After soaking, rinse the filters thoroughly under clean water to remove the hydrogen peroxide solution. This step ensures that no residual solution stays on the filters, which could potentially damage the aircon unit.

  • Dry Filters

Allow filters to dry completely before reassembling the unit. The filters should be completely free of moisture to prevent mold growth.

Step 3: Cleaning the Front Cover

Clean the fron cover of the window air conditioner
  • Use a soft cloth with a sufficient amount of mild detergent to clean the front cover.
  • Rinse the cover thoroughly and let it dry completely before putting it back on the aircon.

Step 4: Carefully Clean the Cooling Fins

Using a fin comb, gently and carefully clean the cooling fins. These aluminum fins are the thin, delicate metal parts around the compressor. Avoid applying too much pressure, as cooling fins can easily bend or become damaged.

Step 5: Clean the Drain Pan

Some window-type aircon units have a drain pan to catch condensed water inside the aircon. Consult the user manual to locate it and remove it. Clean the drain pan thoroughly using warm water, mild detergent, and a soft cloth.

Step 6: Clean the Evaporator Coils and Condenser Coils

Clean the coils of window AC unit

The condenser coils, located outside in the aircon unit, transform refrigerant into a pressurized, hot gas. In contrast, the indoor unit’s evaporator coil, made of copper or aluminum tubes, absorbs indoor heat.

These components are sensitive, so you must treat them with care during any cleaning or maintenance activity. Ensure not to stretch or bend the coils during the cleaning process.

The coil cleaning process is as follows:

  • Apply the coil cleaner to the coils according to the manufacturer’s instructions.
  • Carefully wipe them down with a damp cloth and mild detergent. You can use a soft-bristled brush to clean the coils, making sure to avoid damaging the fins.
  • Rinse the coils thoroughly and let them dry completely before putting the front cover back on.

Step 7: Cleaning the Exterior

  • Use a soft cloth with a sufficient amount of mild detergent to clean the exterior of the aircon.
  • Rinse the aircon thoroughly and let it dry completely before plugging it back in.

Step 8: Reassemble the Window AC Unit

Once all parts are thoroughly cleaned and dry, carefully reassemble the unit. Begin by replacing the filters, followed by the drain pan and cooling fins (if previously removed). Lastly, reattach the front cover.

Step 9: Test the Unit

After reassembling the aircon unit, plug it back in and restore power (including connecting remote controllers, if any). Test the aircon, ensuring that it is running smoothly and that there are no leaks or strange noises.

It’s important to clean your window aircon regularly. However, if you’re unsure how to clean the window-type aircon on your own, refer to the manufacturer’s instructions or consult a professional.

Benefits of Regularly Cleaning Your Window Air Conditioners

Proper care and maintenance are critical for the optimal functioning of window air conditioners. By cleaning your aircon regularly, you can reap several invaluable benefits that not only improve your home’s comfort but also contribute to your well-being.

Here are three primary advantages of keeping your window air conditioner clean:

Enhances Energy Efficiency

Dust, dirt, and debris tend to accumulate in the filters, coils, and other parts of your window air conditioner. This build-up forces the unit to work harder to maintain the desired temperature, thus consuming more energy.

Regularly cleaning your aircon reduces the strain on the system, consequently enhancing its energy efficiency. A more energy-efficient unit translates to lower energy consumption and reduced utility bills.

Reduces the Risk of Unit Breakdowns

When dirt and grime accumulate in your window air conditioner, it negatively impacts the unit’s performance. Over time, excessive dirt in crucial components such as evaporator coils or filters may lead to severe consequences, including system corrosion, freezing, or overheating, resulting in potential breakdowns.

Regularly cleaning and maintaining your aircon significantly decreases the risk of system failures and prolongs the unit’s lifespan.

Minimizes the Release of Allergens and Pollutants

Maintaining a clean window air conditioner plays a vital role in improving indoor air quality.

Unclean aircons can harbor dust, mold, mildew, and pollen, providing a breeding ground for harmful allergens, contaminants, and pathogens. These pollutants can exacerbate respiratory issues, lead to allergies, or negatively affect sensitive individuals.

Regularly cleaning your aircon minimizes the release of allergens and pollutants, thus safeguarding your health and ensuring a cleaner air and fresher indoor environment.
