Air conditioners are a great way to stay cool during hot summer months, but to keep them running efficiently and prevent breakdowns, it’s important to maintain them properly, including regular cleaning. Air conditioner cleaning can help reduce energy bills and improve indoor air quality by removing dirt, dust, and allergens. In this comprehensive guide, we’ll explain how to clean your air conditioner step-by-step.

Before you start cleaning your air conditioner, make sure it’s turned off and unplugged. Additionally, gather the necessary tools and materials, including a screwdriver, vacuum cleaner with brush attachment, garden hose, mild detergent, and a soft-bristled brush.

Step 1: Remove the Filter

The first step in cleaning your air conditioner is to remove the filter. Air filters remove dust, dirt, and other particles from the air before it enters the air conditioner. Over time, the filter can get clogged, reducing airflow and causing the air conditioner to work harder than necessary, leading to higher energy bills and potential breakdowns.

Most air filters are located behind a cover on the front of the air conditioner, which can be easily removed with a screwdriver. Once the cover is removed, gently pull out the filter and set it aside.

Step 2: Clean the Filter

The next step is to clean the filter. Depending on the type of filter, you can either clean it with soap and water or replace it entirely. Check the manufacturer’s instructions to determine the recommended cleaning method for your filter.

If the filter can be cleaned, use a soft-bristled brush or a vacuum cleaner with a brush attachment to remove dirt and dust from the filter. Then, soak the filter in a solution of mild detergent and warm water for 15-30 minutes. Rinse the filter with clean water and let it dry completely before reinserting it into the air conditioner.

If the filter cannot be cleaned and needs to be replaced, purchase a new filter that matches the size and type of the old one. Insert the new filter into the air conditioner, being sure to position it correctly according to the manufacturer’s instructions.

Step 3: Clean the Coils

In addition to the filter, the coils inside the air conditioner can also get dirty and reduce the efficiency of the unit. The coils are responsible for transferring heat from the indoor air to the outside air, and dirt and debris can interfere with this process.

To clean the coils, first remove the cover or panel that provides access to them. Use a soft-bristled brush or a vacuum cleaner with a brush attachment to remove loose dirt and dust. Then, spray the coils with a garden hose to remove any remaining dirt and debris.

If the coils are heavily soiled, you may need to use a coil cleaner solution, which can be purchased at hardware or home improvement stores. Follow the manufacturer’s instructions carefully when using coil cleaner, making sure to wear gloves and eye protection.

Step 4: Clean the Drainage System

As air conditioners cool the air, they also remove moisture from the air, which needs to be drained away to prevent the unit from overflowing or developing mold. Over time, the drain line and drip pan can become clogged with dirt and debris.

To clean the drainage system, first remove the drain line and drip pan from the air conditioner. Use a solution of water and mild detergent to clean both the drain line and pan thoroughly. Rinse them with clean water and let them dry completely before reassembling them.

Step 5: Clean the Outside Unit

The outside unit of an air conditioner is exposed to the elements and can become dirty and clogged with leaves, dirt, and dust, reducing its efficiency. To clean the outside unit, first turn off the power to the unit using the circuit breaker.

Use a garden hose to spray the outside unit, removing any debris or dirt. Avoid using a pressure washer, which can damage the fins or coil of the unit. Then, clean the fins of the unit using a soft-bristled brush or a vacuum cleaner with a brush attachment.

Step 6: Reassemble the Air Conditioner

Once all components of the air conditioner have been cleaned and allowed to dry completely, it’s time to reassemble the unit. Replace the filter, cover, and panels according to the manufacturer’s instructions. Make sure that all parts are properly aligned and securely fastened.

Step 7: Turn the Power Back On

Finally, turn the power back on to the air conditioner using the circuit breaker. Turn the air conditioner on to test its efficiency and ensure that it’s running properly. If the air conditioner isn’t cooling properly, or if you notice any unusual sounds or smells, call a professional for service.

Conclusion

Cleaning your air conditioner is a simple task that can save you money on energy bills and improve indoor air quality. By following these steps, you can help keep your air conditioner running properly and extend its lifespan. Regular air conditioner cleaning, combined with professional maintenance, can help prevent breakdowns and ensure that your home stays cool and comfortable all summer long.
