Where are the AC coils located?

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.

Can you access evaporator coils?

Your indoor air handling unit should have an access panel that can be removed to expose the evaporator coil. If necessary, check your AC owner’s manual to locate the access panel and evaporator coil. Turn the air conditioner off at the thermostat. Remove the screws or other fasteners to loosen the access panel.
