I have never had a vehicle with aircon before, so the system on my 110 is quite new to me. We have had a few hot days recently so had the system on, and I noticed it is not as cold as I remember. We don't use it all the time but over the winter I did have it on to help defrost the vehicle. Is there any reason why it is not getting as cold? I remember having to turn the outlet away from my hand as it was freezing my fingers last summer.
Any ideas please? 2011 110 USW 1973 Series III 1-Ton 1972 Series III 1-Ton Cherrypicker 1969 IIA 1-Ton 1966 IIA 88" |

most aircon systems will lose 10% of there gas every year
most o ring leaks are where the alley pipe corrodes and the corrosion creeps inside under o ring be honest never seen a o ring dryed out causing a leak but say it could be possible , maybe on a very old system or on system that's had a gas swap from old gas ( now banned ) to r134a as you need different o rings and hoses but yes aircon should be run every now and then to mix oil and gas up around the system |

I guess the gas will not have been looked at when serviced - is this a dealer job or can anyone do it?
The vehicle is just coming up to 3 years old. 2011 110 USW 1973 Series III 1-Ton 1972 Series III 1-Ton Cherrypicker 1969 IIA 1-Ton 1966 IIA 88" |

never heard of it during service , doesn't have to be dealer , they will charge a lot more , any garage with a machine can do it , to be done properly it needs vacuuming for 20 -25 mins to dry out system , then refill
even if they have a lot of gas left in them when there degassed , vacuumed, then Regased they always seem to work better and you should get bit of fresh oil added so that's a good reason to get it done is the electric fan running ok on the aircon condenser in the front |

Okay, I will see what i can do. Having a new windscreen in tomorrow and MOT the day after and front brake pad replacement. Rear pads and aircon can wait a bit then. 2011 110 USW

Looks forward attachments radiator cooling. It is made by aluminum "pop" rivets which are often degraded and then, vibration eventually break the radiator, resulting in a loss of gas.
Mine (190.000km) was re-soldered 2 times. Now, I think that I will change it |

Most halfords/quick fit/MOT places will do an aircon re gas.
Or halfords/garages also sell DIY cans which work ok, if it's not empty (just a top up therefore) but they're not usually enough if dead empty. More than doable yourself even for the most inept mechanic  Cheers, David

Kwick fit do it for Ł50. Guaranteed to work, and for a couple of years.

a lot of the small top up cans contain sealer , it might work but never as good and even if you have it done properly after it will never work as good again also you don't know how much gas is in the system to start with , and more gas than its designed for will make it blow warm and overheat the system |
