It’s summertime and that means your air-conditioning units will be getting put to work. Make sure they're in tip-top shape and clean before the hot summer months arrive by giving them a quick cleaning. Here’s our five-step method.

Garden hose

*Tip: Find a small-bristled brush at your local hardware store, or use a kitchen scrub brush.


  1. Unscrew and remove top of unit, or external mesh and paneling, to reach the coils*
  2. Use the brush to carefully remove small, loose debris caught in the coils
  3. Dislodge items the brush couldn’t by carefully using the flat-head screwdriver. Push bent coils back in place
  4. Spray out remaining dirt on the coil with hose. Start at the top and move right to left, sweeping downward, keeping water on low pressure
