To clean your AC condenser coil, you will require a few tools such as grass shears, spray bottle with coil cleaner, soft brush, fin comb, carpenter’s level, pry bar or piece of 2×4, and gravel or rocks.

The majority of condensers are placed outside the house and have a fan that circulates air throughout the condenser coil. Therefore, it is effortless for leaves, dirt, grass, and airborne dust to accumulate in the condenser, leading to a dirty and clogged system. The first step is to cut any vines, weed, or plant obstructions that might be blocking airflow to keep your condenser clean.

Next, use the coil cleaner to clean the coils. You can purchase a bottle of commercial coil cleaner from a refrigerator supply store. The specific instructions for that brand are available on the bottle. Flush out the cleaner and let the coils dry.

Afterwards, clean the fins using a soft brush. The fins are usually delicate, so use a fin comb to straighten them if they are bent. Do not use water or a hose as it can turn the dirt into mud.

The final step is to ensure that the concrete slab on which the condenser sits is level. Use a carpenter’s level on top of the unit to check if the unit is levelled. If not, use a pry bar and/or rocks to raise the unit to the required level.

The best way to keep your condenser clean is to prevent it from getting dirty in the first place. You can purchase a commercial condenser cover that fits over your unit’s condenser.
