This is a brief video of how I cleaned my air conditioner blower motor and blade. It is a simple process and can be achieved by anyone with a socket wrench and some time.

Blower motors can be very costly not only to replace, but also when working poorly. Keeping the motor and a/c blower blades cleaned will increase the power of your system. This in turn will cool and heat your house much quicker. The less your air conditioner runs, the lower your electric bill will be. Nuff said!

If you have rust on your blower blade, it is wise to clean as much off as possible. Prep the surface by taking as much of the crud off of the blades. Then paint it with a rust resistant paint. This will increase the effectiveness of your air conditioner. You'll be amazed at how powerful the air is coming out of your air conditioner vents.

Air conditioner blower blades can be expensive to replace. So make the most of what you have and restore yours.

  • I would like to do this to my motor. It would be interesting to take amp readings of the motor before and after. If I do it ill let you know what I find. How was your airflow after that? I bet it increased.

  • @tkarmakid Please do. Even though technically speaking added paint adds weight, the smooth surface far surpasses it's effects. It is like the difference between a dull blade and a sharp one. It doesn't matter how heavy it is. It still cuts better. Let me know. Would be interested since you have the equipment to test it. The air flow was amazing. It blew out the air ducts clean. I had black stuff come out all over the place after tweaking the blade.

  • good vid. one thing people may want to know, is that yellow cap on the side of the motor is where you put the oil (not motor oil, we use turbine oil, you should be able to get it at walmart) while you have it out, take that plug out, find what looks like a small sponge next to the shaft inside that hole, and put a few drops of turbine oil there. btw, don't expect your motor to come off easy, more often than not, i have to get my puller to get them off.

  • @VonDuross Great advice. Although I'd recommend purchasing the oil someplace else. I do not endorse Walmart and have removed them from any advertising on this channel. Walmart does not deserve your business. Trust me on this.

    The oil can be purchased at Home Depot, Lowes, even OReilly's Auto Parts. Make sure you don't break off the yellow piece as well. They become brittle over time and can break off into the oil hole. :) Thanks again for your tip!

  • Did u use a wet toothbrush to clean the motor housing? No no no... keep your motor away from moisture. Its windings will thank you. I know yours works still but why take the chance? It doesn't need to be that shiny lol

  • @bkcharter I did not use anything wet around the motor housing except a dust cloth and compressed air. So right about the moisture. Don't want that thing to get wet.

  • It is very hot where I live. So, doing anything you can to save money on air conditioning is a requirement.

  • Good work !

  • Keeping this thing clean has lowered our electric bill by about 30 bucks a month. I compared the figures this year to last year, even with higher utility costs.
