1. Clean the filter

The most important thing you can do to maintain your window air conditioner running properly is to clean the filter. The filter should be cleaned every month, even if you do not clean the rest of the device. To put it another way, this is how you go about it.

Before you remove the front panel and remove the filter, ensure sure your air conditioner is not plugged into anything. Use a vacuum to remove as much dust and hair as possible if it is covered. When you’re finished, rinse and air-dry your filter. Once it’s dry, place it back in your window air conditioner.

The air conditioner filter should also be replaced on a regular basis. You should change your AC filter every six weeks to six months, depending on how often you use it and the weather conditions in your area.

2. Wipe down the grill and exterior

The grill should be cleaned with warm water and mild detergent while your filter is drying. It’s also possible to use a moist, washable cloth to wipe it down, but be sure to clean carefully in the crevices where air is free to flow out. Before reattaching it, allow it to dry thoroughly.

After cleaning the grill, wipe off the air conditioner’s outside. Be cautious while entering tight spaces where dirt and dust can easily accumulate. Running the appliance until the grill and exterior are completely dry is not recommended.

3. Dust off the fins and coils

It’s time to put on your work gloves and dive into your air conditioner. Even while you don’t have to clean the air conditioner every time you clean it, most manufacturers recommend that you do it every three to six months.

Use a soft-bristle brush to carefully clean the aluminum fins in your air conditioner first. In order to avoid damaging the fins during this process, you should take your time with it. Softly adjust any bent fins back to their original position.

Next, spray the coils with a can of condensed air to remove any dust. In order to ensure that your appliance functions properly, you should be as thorough as possible when cleaning it.

4. Clean out the tray and drain

Clear the drain and empty the drip tray of your window air conditioner to complete the interior cleaning. Grab a wet-dry vacuum (if you have one) or a damp towel and remove any debris or dirty water that has accumulated in your tray. Before putting it back together, let it dry.

Finally, inspect the drain to see if anything is obstructing it.. Make sure there is a clean passage for water to depart your unit by wiping around the aperture with your cloth.
