Ours also cycles between blowing very cold to slightly less cold, if you listen to the engine you can time this to the air con compressor activating in and out. I believe this is a normal function in the system design ref its sensor response time .. the time between cycles is fairly short. Our system has always done this even when regassed. We had an issue when the car was almost new of losing gas, the main dealer chased this on and off for almost 2 years, in the end the pipes seals were replaced, as high hamster says when the gas has leaked out the aircon button light will flash. Since the seals were replaced its worked as described. We tested it out in France recently in 38 deg in shade heat and it performed ok.
If in doubt about your cars system let the main dealer have a look at it.
