Renault Clio - aircon intermittent - malct

I recently had my air con re gassed in December and the guy from Protyre mentioned that it wasn't cool enough and to take it back to be checked over after 2 weeks, Because it was winter time, It was hard to judge if it was cold or not but i could feel that it was a little icey .on the fingers when the air con was blowing , But i took my car back to be checked and to be honest, it felt worse and could not feel the ice cold air on my fingers.

Now we have this hot weather, The air con is luke warm/cold , But not ice cold , But then it will run cold for a matter of a minute and then back to luke warm.

I am going to take advantage of a free air con check at Protyers next week and i have just spoke with the service manager who explained that my car should be OK or they would not have been able to Re gas in December, So i thought that i would ask your thoughts before i go and take it for a Air con Check .

Very likely to be low on gas due to a leak in the system . How old is the car?

Usually a good idea to replace the hoses when regassing. Nothing worse than a new lot of gas blowing an old hose and then you lose all the gas.

The car is 7 years old, it's just a manual air con with the button, feeling the air con pipes, the large one is cold while the thin pipe is luke warm, I am not sure which will be the return pipe. The guy from pro tyre informed me that if anything was wrong, it would have been picked up, but something isn't quite right.. however, it's not uncomfortable warm, but could do with it colder

The thin pipe is the hi pressure line and should be hot ( untouchable under certain conditions ) . The larger pipe is the low pressure and should be very cold to touch . Think you’ve got inadequate gas in the system. If you’ve got a digital thermometer. Face vent temp on a day like today should be 5-10 degrees.

Does it have an air conditioning "Electronic Solenoid Control Valve" which can fail/stick? Many later aircon compressors have a control valve rather than an on/off compressor clutch.

Some cars have a clutch type pump , some have a solenoid valve and some have both . But without the correct gas quantity in the system, nothing is going to work properly.

Agreed, but in the original post it was mentioned that it wasn't cold enough even just after a re-gas. An proper aircon specialist is what's required really - it needs properly diagnosing.
