Air Conditioner Blower Cleaning.

About: Update 12 September 2017: A very special thanks to Sam Elder, a manager here at Instructables, who tracked down the cause of my lost publications and fixed the issue. Take a bow Sam!

This instructable shows how to clean the blower unit in half hour or less. To reach the blower I used a step ladder but depending on your height you may need something taller.

Step 1: Cleaning the Air Filters.

Flipping the cover to access the washable filters. I cleaned mine with soap water and a cleaning pad.

Step 2: Gaining Access.

I removed the flap and air vanes to gain access to the impeller.

Step 3: Cleaning the Impeller.

This is the most time consuming task. Using a half inch paint brush I thoroughly cleaned the fins of the impeller. One hand to steady the impeller and the other to brush. Lots of caked up dirt came out. It's a good idea to wear a head mounted flashlight and a respirator.

Step 4: Cleaning Up Debris.

I used a damp rag to wipe out the fallen debris. After washing the rag I wiped the entire surface of the impeller.

Step 5: Completion!

I turned on the unit and more debris spewed out. I used a vacuum cleaner on the carpet to clean out the ejected stuff. Now the airflow is back to OEM spec and the room cools a bit better than before.
