Here is how to clean AC outdoor unit with pressure washer:
First, switch off the AC power from the main switch. This is important for safety. Never clean the unit while electricity is on.
After that, remove dry leaves, dust, and plastic pieces around the outdoor unit. You can use your hands or a small brush.
Next, check the metal fins on the outdoor unit. These fins collect dirt and block air flow. When air cannot move properly, the AC does not cool effectively, and the electricity bill increases.
Use normal water first to soften the dirt. After that, use the pressure washer slowly. Keep the pressure low because very high pressure can bend or damage the fins.
Always spray water from top to bottom. Do not spray from a very close distance. Keep at least 1 to 2 feet of distance between the washer and the AC unit.
Move the spray slowly and clean all sides carefully. If dirt is very hard, spray water again and wait for a few minutes before cleaning.
Do not spray water directly on electrical wires or the control box. Cover the electrical area with plastic before washing.
This protects the parts from water damage.
If the fins become bent, you can straighten them gently with a fin comb or soft brush.
After cleaning, let the outdoor unit dry for at least 30 minutes.
Finally, remove the plastic cover from the electrical parts and switch on the AC. You may notice better cooling and less noise after cleaning.
It is good to clean the outdoor unit every 3 to 6 months, especially in dusty areas. Regular cleaning improves cooling, saves electricity, and increases AC life. I hope you got a clear idea about the steps to clean the AC outdoor unit with a pressure washer.
