How to Pressure Wash & Clean Window Unit Air Conditioners
Cleaning the condenser coils on a window air conditioning unit helps the appliance draw air and cool the room more efficiently. Over time, grime and dirt can build up between the thin metal plates, forcing the motor to run harder and potentially wearing out the unit much more quickly. Mold and mildew can also accumulate on the metal fins. The force of a pressure washer makes fast work of this tough cleaning job, but you'll need to take precautions to save time without damaging the air conditioner.
