Also, can AC coil be cleaned?
To clean your indoor evaporator coil, the contractor will most likely clear larger debris by hand or with a special brush, then follow up by applying a self-rinsing evaporator oil product. This product will clean the coil effectively and rinse off during the cooling process when the system is turned on.
People also ask, where are the coils in a window AC unit?
A window air conditioner has two sets of coils, the evaporator coil in the front—the room side—and the condenser coil in the back, facing outside. Their purpose is to transfer heat from inside the room to the outdoors, so the coils are covered with delicate aluminum fins.
