Many times, when it comes time to perform an annual maintenance service on your HVAC system, components that are out of sight inside the arrangement chiffonier or air handler enclosure are ofttimes forgotten about or overlooked. Ane of these important components are your Air-conditioning unit's evaporator coils. When the Air conditioning coils get dirty, the arrangement loses efficiency and performance and can likewise consequence in a breakup or damage to the system itself. Co-ordinate to energy.gov, having clean air-conditioning coils is an essential office of maintaining your air conditioner. Before tackling the cleaning of your Ac coils, it's important to have some basic cognition on how your air conditioner functions, plus the importance of the evaporator coils.

While the evaporator coils do their job, the condenser coils (also normally called the fan coils) release the trapped oestrus into the air around the outdoor unit. Both coils are typically made of copper and are encased by multiple aluminum fins that aid improve the transfer of heat.
