The air conditioning coil is usually placed above the furnace. When dust passes through the filter and also goes through the blower, it starts to build upon the coil, which in turn restricts airflow through the house. Also, consequent leaks and cracks lead to a decrease in the cooling potential of the air conditioner. At DuctsCare, we believe that cleaning air conditioning coils regularly is crucial to the long term health of the air conditioner. Not only does the cleaning increase the system’s life expectancy but it also helps you save money.
