# How to Change a Condenser Coil in a Central AC
Some air conditioning systems include an evaporator coil. In the case of older split systems, or ones that have failed, evaporator coils will need to be replaced with a condenser coil. For new systems that need a replacement condenser coil, you will be able to find the old one within the condensing unit of the central AC unit.
