  • Thanks for sharing this advice on what you should and shouldn't do with your air conditioner maintenance. I had no idea that using anything sharp at all could damage condenser fins and cause leaks! If that's the case, then AC systems aren't as durable as I imagined.

  • Thanks for the tips! It is important to service your air conditioning system regularly, though not a lot of people do that. I have written about the importance of regular aircon maintenance. Check out my post here:
  • Remove the outer covers and use the brush attachment on a powerful shop vacuum to remove all outside dirt. Then, using a gentle stream from a garden hose, spray through the fins from the inside out to remove any built-up dirt or debris from between them (Image 1). Never use a pressure washer, since the pressure can damage the fins.
