DIY Air Conditioner Spring Cleaning

Cleaning your outdoor Air Conditioner Condensing Unit or Condenser is one of the easiest ways you can not only reduce operating costs, but also extend the life of your AC Compressor! All you need is a garden hose, a bit of cleaning solution and a soft brush if its very dirty!

AC Blowing Warm Air? Clean It!

Springtime, or at least the first day over 80 degrees, always means a large volume of calls to local HVAC companies as people realize their air conditioner is not cooling their home enough! Many people worry that the worst has happened and they will need to hear their repairman tell them they need to replace their unit! 15-209 minutes of time now, could prevent the call from happening all together!

Why Do You Need to Clean your Outdoor Air Conditioner?

The fins you see wrapping the outside of your air conditioner are much more than just cosmetic! They dissipate 100% of the heat from the freon in your system, so it can be compressed and return to cool your home. If those fins are bent or dirty, the heat will not dissipate as it needs to, and the result will be nice warm and humid air from your AC vents!

A Dirty Outdoor Condenser:

  1. Reduces Airflow
  2. Reduces Heat Transfer
  3. Reduces Efficiency
  4. Makes the Compressor work Harder
  5. Reduces Equipment Life
  6. Increases Repair Costs!

Bottom Line – A Dirty Outdoor Air Conditioner Costs you Money!

Cleaning your Outdoor Air Conditioner

There is no need to make sure your unit is turned off during this procedure.

  1. Make sure you have already done your weedeating, and there is no stray grass or weeds growing into or covering the lower coils of the unit.
  2. Using your Garden Hose, Spray off the unit from the top down.
  3. Mix or Spray your AC cleaning solution onto your outdoor unit (If you don't have AC Cleaner, Soapy water is fine)
  4. Using your soft brush, gently scrub the cooling fins and all sides of your air conditioner.
  5. Rinse off the unit, spraying as much as possible from the inside, to force all debris out of the unit. You can do this by simply focusing your spray into the top or side grate where the condenser fan is.

This simple process should be done EVERY MONTH during the cooling season, and you should make sure the unit stays clean and free of any obstructions, year round.DIY Air Conditioner Spring Cleaning

    @ Pete –

    You don’t… Chances are, its pretty dusted over if its very loud.

    Turn off the power to the unit first, and take the fan cover apart. Look inside to see if there is build-up of debris or dirt on the fan itself, or within the fan motor assembly.
