Step-by-Step to Clean an Aircon Outdoor Unit
Step 1: Turn Off the Power
The first step in the cleaning process is to turn off the source of electricity. This is done by switching the aircon breaker and the breaker controlling the electricity supply to the aircon off. If there is no dedicated breaker to control the supply to the aircon, you may need to shut the main breaker off.
Step 2: Clear Debris from the Unit
When you are sure the aircon is disconnected from the electrical supply, start by cleaning the visible debris or dust particles. Clean the area around the outdoor unit to ensure proper airflow.
Step 3: Remove the Outer Cover
If your aircon outdoor unit has an outer cover, remove it to access the coils and fins. Carefully remove the cover and use a screwdriver if needed. Keep the screws safe to hold the cover after reassembling the unit.
Step 4: Clean the Fins and Coils
The fins and coils are the components responsible for heat exchange. Over time, they can catch up with dust and dirt. You need to clean them as explained below.
Vacuum the Fins
Use a vacuum cleaner with a brush attachment to gently remove loose dirt and debris from the fins. Be careful not to bend the fins as they are delicate.
Brush the Coils
Use a soft brush or cloth to clean the coils. If stubborn dirt remains, you can use a coil cleaner. Spray the cleaner on the coils, following the instructions on the product, and let it sit for a few minutes before rinsing it off with a hose.
Rinse with Water
Use a garden hose with a spray nozzle to rinse off the coils and fins. Spray from the inside out to push the dirt outward. Avoid using high pressure as it can damage the fins.
Step 5: Straighten Bent Fins
If you notice any bent fins, straighten them using a fin comb. This step is optional but recommended for optimal airflow. Carefully comb the fins into place without damaging them to ensure proper airflow.
Step 6: Clean the Surrounding Area
After you clean the fins and coils, clean the surrounding area. Remove any further debris accumulated around the aircon outdoor unit area. This is to ensure there are no obstructions to airflow.
Step 7: Reassemble the Unit
When the outdoor unit is clean and dry, and the fins are well placed, reassemble the outer cover. Tighten the screws that you saved earlier. Ensure the cover is appropriately fit, and there is nothing loose or in danger of falling.
Step 8: Restore Power
Once the unit is fully reassembled, you can restore power by switching the circuit breaker back on. Turn the aircon on and check to ensure it is running smoothly. Listen for any unusual noises and feel for consistent airflow.
When you have successfully cleaned and reassembled the outdoor aircon unit, turn the power on and run the aircon to check the instant results. If there is any issue, you may need to hire a professional.
Conclusion
In conclusion, you can clean an outdoor aircon unit yourself with some essential tools and an understanding of the process. Regular maintenance of the aircon unit is essential to keep it in good health and enhance its overall lifespan. The above steps explain cleaning the aircon outdoor unit to increase cooling efficiency and airflow. Running away from regular maintenance can cost you heavy replacements or repairs.
