The AC compressor will not activate. The compressor is intended to circulate refrigerant through the evaporator. It depends on maintaining a predetermined pressure to operate. As such, if there is a leak, there is reduced pressure within the system and the compressor will not activate.

What does a leak in the evaporator coil do?

Also known as the evaporator core, this component helps regulate AC temperature by cycling refrigerant through the system–essentially converting warm air to cool air with the help of the engine’s blower fan and compressor. A leak in the evaporator coil disrupts this process and eventually causes the system to fail.
