You could also use a homemade mix of water and mild detergent (like dish soap) instead of commercial chemical cleaners. After cleaning the coils, it's also a good time to inspect the other parts of the unit. Inspect the condensate drain pan and remove anything that doesn't belong there.
While Dawn dish soap is a versatile cleaning agent, it's not recommended for cleaning AC coils due to its chemical composition. Household cleaners like Dawn may not effectively remove stubborn buildup and could potentially harm the coils or other components of the system.
Use a hose to spray your AC unit from the inside outward, without soaking the disconnect or the electrical components inside the access panel. Apply cleaner to coils. To ensure foaming, use a pressurized, pump-up, or spray applicator. Avoid spraying onto electrical wires or connections.

Any debris that is stuck can be worked away using your soft bristle brush. Make sure you are not using a metal or wire brush because it can damage the coils.
Dirty AC coils become insulated rather than able to release heat the system extracts from the air. The system will therefore struggle to cool your home. Indoor air can become more humid too, as the system won't be able to extract as much moisture, making things extremely uncomfortable in the summer.
