DIY Life has a reminder article about getting your air conditioner condenser ready for the new season. Around here, it’s a bit early for that, but it won’t be long before the list below will be on the corkboard todo list

  • Straighten the evaporator fins. These form the sides of the unit. Are some of the fins bent from bumping them with the mower or Frisbee? Straighten them out using a fin comb. (Yes, such things do exist! I knew you were going to ask.)
  • Clean the fins. Use a soft brush and soapy water to clean them.
  • Clean the drain pan. Don’t let it get full of leaves. Finally, pour in a half cup of bleach or use algaecide tablets to stop the funky stuff.
  • Level the condenser. Use a two or a four foot level. If it’s out of level in any direction, across the top of the unit, shim it up. This will keep the refrigerant flowing the way it was designed.
  • And finally, start the summer off with a new air return filter. Change it monthly.
