How to clean your outside AC unit like a pro


Throughout the year, the outdoor components of your AC unit are regularly
subjected to leaves, dust, and dirt among other contaminants. Did you
know that all this is costing you money? Del-Air, your
AC repair expert, offers advice on how to properly clean your outside AC unit. Our
goal is to keep your system running strong while minimizing utility bills
in the coming years.

Tools You Will Need

Before you can start cleaning your outdoor AC unit like the pros do, it’s
important to gather the necessary professional tools for the job. Purchase
the following items before you get started:

  • AC coil cleaner (follow your AC maker’s recommendation)
  • Garden hose with sprayer
  • Gloves and eye protection


  • Find the electrical disconnect near your outside unit. These components
    are typically located in a metal box.
  • Open the electrical disconnect and find the switch that turns off the air
    conditioner. It’s important to make sure the system is off before
    attempting any cleaning procedures.
  • Use the water hose spray to clean off loose debris on the outside unit.
    Contaminants like dust, grass, leaves, and dirt can collect on these components
    and affect the quality of air your family is breathing.
  • Spray the outside unit with the coil cleaner. Typically made from heavy-duty
    detergents, coil cleaners have the strength to remove grease, oil, and debris.
  • Wait 10-15 minutes for the cleaner foam to bond with the dirt on the coils.
  • Rinse the coil cleaner off with the hose to remove all the foam and debris.

Perform the above steps each year to maximize AC performance and indoor
air quality while minimizing utility costs. The end result is a more comfortable,
healthy home for you and your loved ones.
