Air conditioning units rely on coils to function properly. These coils are responsible for transferring heat from inside the building to the outside. Over time, these coils can become dirty, which can reduce the efficiency of the unit and increase energy consumption. Cleaning the coils is an essential maintenance task that can help extend the lifespan of your air conditioner and improve its performance. In this article, we will discuss how to clean the coils in an air conditioner.
Turn off the Power
Before cleaning the coils, it is crucial to turn off the power to the air conditioner. This can be done by switching off the circuit breaker that controls the unit. It is also essential to wait for a few minutes after turning off the power to ensure that the unit is completely off.
Remove the Outer Cover
Next, remove the outer cover of the air conditioner to access the coils. This can usually be done by unscrewing a few screws or releasing clips. Be sure to keep the screws and clips in a safe place to prevent them from getting lost.
Use a Soft Brush to Remove Debris
Using a soft-bristled brush, gently remove any debris from the coils. Be careful not to bend or damage the fins, which are thin pieces of metal that surround the coils. Start at the top of the coils and work your way down, brushing in the direction of the fins. This will help loosen any dirt or debris that may be stuck to the coils.
Vacuum the Coils
After brushing the coils, use a vacuum cleaner with a soft brush attachment to remove any remaining debris. This will help ensure that the coils are completely clean and free of dirt and dust. Be sure to vacuum both sides of the coils and pay special attention to the areas between the fins.
Use a Coil Cleaner
If the coils are heavily soiled or have not been cleaned in a long time, it may be necessary to use a coil cleaner. These cleaners are specially formulated to remove dirt, grease, and other contaminants from the coils. Be sure to follow the instructions on the label carefully, as some cleaners may require dilution before use.
Rinse the Coils
After using a coil cleaner, rinse the coils thoroughly with water. This can be done using a garden hose or a spray bottle. Be sure to rinse both sides of the coils to ensure that all the cleaner and debris are removed.
Allow the Coils to Dry
Once the coils are clean and rinsed, allow them to dry completely before reinstalling the outer cover. This can be done by letting them air dry or using a fan to speed up the process. It is essential to ensure that the coils are completely dry before turning the power back on, as moisture can damage the unit and reduce its lifespan.
Reinstall the Outer Cover
Finally, reinstall the outer cover of the air conditioner, making sure that all screws or clips are securely fastened. Turn the power back on and test the unit to ensure that it is working properly.
Conclusion
Cleaning the coils in an air conditioner is an essential maintenance task that can help improve the unit’s efficiency and extend its lifespan. By following these simple steps, you can clean the coils yourself and avoid the cost of hiring a professional. However, if you are unsure about any aspect of the cleaning process or do not feel comfortable doing it yourself, it is always best to seek the advice of a qualified HVAC technician.
