The air conditioner’s evaporator coil and condenser coil will collect dirt over the months and years of service and usage. A clean filter prevents the evaporator coil from soiling quickly, however, the evaporator coil will still collect dirt over time. This dirt reduces airflow and insulates the coil, reducing its ability to absorb heat effectively. To avoid this problem, check your evaporator coil every year and clean it as necessary.
Outdoor condenser coils can also become very dirty if the outdoor environment is dusty or if there is foliage nearby. You can easily see the condenser coil and notice if dirt is collecting on its fins.
You should minimize dirt and debris near the condenser unit in order to optimize your unit’s performance. Your dryer vents, falling leaves, and lawn mower are all potential sources of dirt and debris when they’re near your unit. Cleaning the area around the coil, removing any debris, and trimming foliage back at least 2 feet (0.6 meters) will allow for adequate airflow around the condenser.
Coil Fins
The aluminum fins on the evaporator and condenser coils are easily bent and can block airflow through the coil. Air conditioning wholesalers sell a tool called a “fin comb” that will comb these fins back into nearly original condition.
Condensate Drains
Occasionally pass a stiff wire through the unit’s drain channels. Clogged drain channels prevent a unit from reducing humidity, and the resulting excess moisture may discolor walls or carpets and make your interior air humid, which can lead to mold or mildew build-up.
