People are often hesitant to spray water directly onto a running air conditioner. The reason is the worry that splashing water on a running electrical appliance may cause a fire, short circuit, or fry the HVAC.

Yes, spraying water on your air conditioner while running is okay. Don’t panic! To run efficiently, the condenser unit of your AC needs occasional spraying to remove dirt, grass chips, and other debris to keep it running efficiently.

Connect a garden hose and spray the air conditioner thoroughly for an excellent outside wash. You don’t even need to be gentle. Please set it to a hard stream and run water over the system from top to bottom till it’s squeaky clean.

However, some parts of the air conditioning system should be left dry. Be careful not to get water into these parts as it might fault the unit, and you’ll have to call a professional for assistance.

Advantages of Spraying Water on Your Air Conditioner

There are several perks to the regular spritz on your unit. They include the following:

Increase Durability

In addition, pay attention to the filters as well. Clogged filters can cause severe faults in your air conditioner. You must clean and change your filters every 60-90 days.
