Aircon blower wheel or the roller gets dirty too often. Cleaning your aircon blower is important to maintain the freshness of the indoor environment. A dirty blower can blow dust and bad smells into your room. Many people think they need to take the aircon apart to clean the roller. But you can clean it without dismantling it. Let’s know how you can clean the blower wheel of the aircon in a few simple steps with a few tools.
Why Clean the Aircon Blower?
The blower is a roller like aircon component that pushes cold air into the room. Over time, it collects dust and gets dirty. This can cause several problems:
- Weak airflow – because it blocks the roller blades
- Bad odor – because of mold or bacterial growth
- Higher electricity bills – because the blower works harder
- Noisy operation
- Health issues like allergies
That’s the reason you need to keep the blower wheel clean. Cleaning the blower helps solve these problems.
What You Need to Clean Aircon Roller
Before starting the cleaning process, you need gather below tools:
- A soft brush
- A dry or slightly damp cloth
- A vacuum cleaner with a narrow nozzle
- A blower or air compressor (optional)
- An aircon coil cleaner or foam spray (optional)
- Safety gloves and mask
Cleaning Aircon Blower Wheel: Step-by-Step
After you have gathered all the required tools, let’s clean the blower in a few steps.
Step 1: Turn Off the Power
Safety first. Turn off the power to the aircon unit. Turn off the breaker or unplug the system whether it’s a window or wall mounted split type aircon.
Step 2: Open the Front Panel
Lift or pull open the front cover. Most panels can be lifted easily without tools. You will now see the filters and coils.
Step 3: Remove the Air Filters
Take out the air filters. Wash them with water and soap. Let them dry in the sun. This step makes sure the filters do not create any blockage during the cleaning process.
Step 4: Locate the Blower Wheel
Look near the evaporator coil (the cold coil). You’ll see a long cylindrical fan – that’s the blower wheel. It may be partly hidden, but enough of it is visible for surface cleaning.
Step 5: Vacuum the Blower Surface
Use a narrow nozzle vacuum cleaner to suck up loose dust and dirt. Do this gently. Be careful not to damage the fins or bend any parts.
Step 6: Use a Brush for Stubborn Dirt
A soft brush works well to remove sticky dust on the blower fins. Rotate the fan slowly by hand and clean section by section.
Step 7: Use a Foam Cleaner (Optional)
You can spray coil cleaner or foam spray into the blower area. Let it sit for 5–10 minutes. It will loosen up hidden dirt. After that, wipe gently with a cloth or use a vacuum to suck out the loosened dirt.
Note: Use only no-rinse cleaners made for air conditioners.
Step 8: Use Air Pressure (Optional)
If you have a blower machine or air compressor, use it to blow air into the blower wheel. This helps remove dust from tight spots. Use short bursts of air, and always wear a mask.
Step 9: Clean the Surrounding Area
Wipe the nearby parts of the unit. Clean the evaporator fins gently. Also, wipe the drainage area to prevent clogs.
Step 10: Reinstall the Filter and Close the Panel
After cleaning, put the filters back. Close the front panel tightly. Make sure everything is dry before you plug in or turn on the power.
