What is the coil on a split system air conditioner?
In a split-system central air conditioner, there is an indoor unit, typically a furnace and evaporator coil or fan coil, and an outdoor unit, often referred to as the air conditioning unit. Each of these units houses a coil that is vital to the air conditioning process. Inside the home, the evaporator coil, sometimes referred to as the cooling coil, is located on the air intake side of the fan coil or the outlet side of the furnace. Its job is to remove heat from indoor air so the blower fan can return cool, refreshing air to the home.
Why Is It Important to Clean AC Coils?
Due to the tight spacing between the coil fins, surface moisture from the cooling process, and the amount of air that flows across them, dirt, dust, debris and other pollutants can build up on the coil surfaces. Over time, this buildup reduces the system’s ability to transfer heat into and out of the home, thus reducing your system’s ability to provide summer cooling. In more extreme cases, dirty coils can also hinder or block the airflow that is so important to the entire process. This can result in having a less comfortable home and rising utility bills due to the lost energy efficiency. Even worse, dirty coils make the system work harder than intended and can result in shorter system life and potentially expensive repair bills. In short, the cleaner the air conditioning coil, the more efficient the system will operate.
