the system is blowing air but not cold
the system is fully charged r12
i notice frost half way along the POA valve .
lower the expansion valve is not cold ??
the heat works fine .
is the POA valve clogged or the expansion valve bad ?? or what do i need to test .
compressor is running clutch is engaged
