Default A/C Question

The A/C in my 69 coupe is factory original type. According to the previous owner it has been converted to the new refrigerant. My question is that the air works great for a while then it starts to blow cool not cold air, then it starts to blow cold air again. This cycle continues as long as the air is on. Is this normal or is there a problem? And what could cause this cycle to occur.

not normal.
pay attention to speed/rpm and might find a clue.
a symptom like, cold when driving freeway, warm around town
could be under gas charge.
then, cold around town, warm on freeway could be over gassed.
gauges will tell the story
