If you are venturing into a DIY AC repair and maintenance project, here are a few easy steps to help you along in your endeavors:
Shut Off the Power
Due to the moving parts of the air conditioner and the dangers of working around electricity, it is indispensable to cut off the power to the unit before you start your maintenance project. On the exterior compressor/condenser, the shut-off box is usually located near the unit. Indoors, the power to the unit can be turned off at the breaker box.
Remove the fan page on the exterior compressor/ condenser. Remove the fasteners with the help of a wrench or a screw driver, and lift the fan grill or cage away from the unit. Clean debris and leaves from the interior with the help of a vacuum or by hand.
Clean the Fins
Once the outer covers are removed, you can utilize the brush attachment on your vacuum to get rid of all the dirt outside. Direct the stream of water from a garden hose to trickle through the fins from the inside out, eliminating any dirt or built up debris from between them. Avoid using a pressure washer as it can potentially cause damage to the fins. You can also employ a commercially available fin cleaning spray if the fans are really dirty. If you are finding it difficult to clean the fins, you can always ask help from home maintenance services in Dubai.
Straighten the Fins
The efficiency of your unit is greatly reduced if air-flow through the fins is obstructed. Therefore, you have to straighten any bent fins carefully using a commercial fin-straightening tool or a butter knife. Be as gentle as possible since any rash action can damage the embedded tubing within the fins.
Clean Area around the Unit
Replace the fan cage once you are finished cleaning the insides. Rake back debris and leaves in the vicinity of the condenser and clear off vegetation and branches in a 2 feet radius around the condenser to ensure an unconstructive airflow. When the condenser is not in use in off-peak seasons, try to cover the top of your unit with plastic or plywood to keep debris from covering the system. However, refrain from covering the sides of the unit as built up moisture inside can lead to corrosion. Make sure that the unit is not covered when it is running.
