Window air conditioners are good at keeping a room cool but do need maintenance to work properly.
One of the maintenance requirements needed is cleaning the coils inside and outside so that air can flow past the coil and properly remove heat.
If the inside coils become clogged no air can blow past the coils fins which will cause the unit to stop working properly.
Be sure not to bend the coil fins which will block air flow if bent.
Also be sure not to use any chemicals that may blow bad air into a room.
If a cleaner is used be sure it is certified for cleaning the coil as to not have a chemical smell in a home.
How To Clean the Indoor Coil on a Window Air Conditioner
- Open the front panel
- Spray the unit out with water
- After cleaning the coil fins test the unit.
The first thing that needs to be done is to get inside the front panel of your unit.
Using plain water in a spray bottle will work well to get water in-between the fins.
A unit can also be taken out of a home and clean with a hose outside. If a hose is used be sure not to use high water pressure as too much pressure will bend the small fins that dissipate heat.
Bending a few fins will not block much air but bending too many fins will block the air which the unit needs to work properly.
The main goal is to get out any dirt or other debris that has built up blocking the air from coming into a room.
