aircon not working , i bought the car last september and the dealer serviced it and said they had regassed the aircon system, the air con does not cool the air .any thing i can do or is it back to the garage time <they only gave a 3 months warranty .>

Maybe cheaper to use somewhere like ATS etc for a quick recharge.

That should get you through this hot period and if it loses that gas again quickly, ie by next summer, then either "repeat" or get a proper car AC place to locate and resolve the leak.

No reputable A/C technician would (should) simply recharge a system without checking for refrigerant leak first as that is illegal in UK.

That was not the point that I was swerving around!

Any certified place will initially recover and vac out any AC system that they deal with, but after passing this GO/NO GO vac holding test, they can still be reasonable leaks, so no laws are being broken when they recharge - and off you go only to end up having this same issue 2 or 3 months down the line.

It is just the way it is.

I used to get frowned on from above when I always demanded leak fixing on big systems, but doing that meant they remained in use (fridge gas wise) for a long time. And that was even when we complied with F-Gas rules absolutely, no dodgy business allowed!

Ask/pay for the refrigerant recharging again. If it passes an initial leak test but only works for a day or two, there are two probable causes:

1. If you're fortunate: leaking from condenser due to stone damage. ££

2. If you're not fortunate: leaking from evaporator, which requires full dashboard dismantle and reassembly. £££££

PS: it could also be leaking from somewhere else of course. However you should note that the compressor on these is belt driven and runs all the time, so be suspicious if a garage immediately tells you that needs replacing (get a second opinion).
