7 easy steps to clean the dirty window air conditioner
These are the steps to follow.
1. Turn off your air conditioner and unplug it. You must ensure that no electricity is passing through the area while you are working.
2.Next, you will need to take out the front grille to allow you to access the coils and filters inside the window air conditioner. This can often be accomplished by pulling the grille out. However, if the grille is screwed in you will need a screwdriver.
3. Take out the filter. Two types of filters are commonly used in window ACs: reusable and disposable. If you have a disposable filter and the AC shows signs of mold or other dirt, it is time to get a new one. You must clean your filter if it is reusable. You can clean it with warm water and detergent, or dishwashing soap. Use a sponge or soft brush to apply the solution. It can also be left to soak in warm water with detergent to loosen any grime.
4. Now take your vaccum cleaner and clean out any dirt or dust that might have built up inside the unit.
5. Use warm water to soften the dirt. Clean your AC’s interior thoroughly to remove any dirt or visible mold.
Warm water mixed with some bleach is one of the best ways to combat mold. This not only cleans but also kills mold spores. It also stops any future mold growth from happening.
6.After cleaning, you can start to enjoy your clean window air conditioner. Use a towel to dry it. Make sure to dry a reusable filter after washing it.
7.After your filter and unit are completely dry, you can replace the filter. Screw the grille on the front and plug it back in. This will not only eliminate any undesirable side effects of mold but it will also make your air conditioner work more efficiently.
Make sure your window AC runs well for a longer time
These best practices will help you get the most from your window AC unit. These tips will help your AC last longer.
- Regular maintenance checks should be scheduled. You must keep your filter clean and free from dirt or mold buildup. I have found that the filter can become blocked quite quickly in my experience living in the city. Blockage of the filter can cause a reduction in efficiency and increase your electricity bill.
- Regularly use your air conditioner, even in winter! However, it is absurd to use an air conditioner when it is cold outside. We used to experience this every year when summer arrived. After 4 months, the AC would stop working and the air would smell bad from the mold. Mold thrives in the cooler, damp winter air. You can prevent mold from becoming an issue in the summer by only using your AC for a few minutes each day.
- It should be serviced at least once a year. Refrigerant will need to be topped up every two years for AC units. The chemical that cools the air conditioner will run out of refrigerant. Although it is a simple task to refill, it should be handled by professionals.
- It should be well kept. It is best to install it in a more shaded window. Shade is better for your window unit’s lifespan. It’s a good idea to keep it dry and cool when not in use. This will protect it against the winter harshness and early onset of rust.
