  • Air con re gassed but no joy

    Hi all , any advice would be great , I went to halfords for a re gas on the ac , but it was still blowing warm air (did not charge me for this), I have checked fuses , I have it booked in at an air con specialist in morning and on the phone they said 9 out 10 insignias is the condenser , just wondered if any one else has suffered the same before I get there in morning

    Quite a common thing on the Insignia---the condenser is right at the front of the radiator pack and gets all the rubbish off the road thrown at it-so you end up with some holes in it----not a bad job to do-----Dave

        If you are going to do it yourself it will be about £70 for the condenser and new seals---then you have to get it regassed----depends on what the air con guy is going to charge you----there is a few threads on here about changing the condenser------Dave

              halfords should have done a vacuum leak test before trying to regas the system

                I am not sure if they did , the Halford guy never mentioned about it , he just said he's filled it with gas and it's still not working and tgey are not mechanics ��

                  they are supposed to remove all the remaining gas,then leave it on a vacuum for a short period,if the vacuum measurement falls during this test ,then they wont refill,as theres a leak. had my aircon serviced last weekend ,and it was on the vacuum test for 15 mins.luckily mine is ok ,no leaks

                    Places like halfrawds and quackfit just re-charge the A/C system ,they don't recover old refrigerant they don't vacuum, they don't add oil or dye , so they cannot test for leaks .they just take a before and after temperature reading from your air vents , no change then no charge .
                    Correct way should be
                    Initial system test
                    Check system components ( belts , condenser , compressor electrics )
                    Check internal system components ( flaps heating etc )
                    Recover exsisting refigerant
                    Vacuum A/C system
                    Re-gas
                    Add oil and leak detection dye
                    Leak test components
                    Full post A/C test
                    But I always thaught if you are F gas registered , you were supposed to carry out a full , before and after leak test .
                    It's like me being a gas safe registered engineer , and not doing a tightness test , I would soon get , fined , and possibly inprisioned ..

                      That's good point as to me if they are just squirting refrigerant in which is then leaking straight back out "its against law", its the same as just undoing a valve and letting it out into atmosphere but that's the cowboys that some places employ.

                        I always have mine done at ATS, they seem to do all or most of the above. The reason it seems likely is that I was there a long while and they were constantly in and round the car. Mine turned out ok but the customer before me was told that they couldn't do his system as it didn't pass the initial pressure test, what needed repairing and he was only there for about 10 minutes.

                          Vacuum tests will only show severe leaks - the main purpose of the vacuum section of a charge is to boil off any moisture within the system before the gas is re-added. The use of nitrogen is the most common form of testing the system as it places the whole A/C under the same pressure as when it is working. Pressure decay is monitored over time, and then very small leaks/loss of pressure can then be pinpointed using bubble spray.

                          There is also newer tracer gas available which has a very small trace (5%) of hydrogen within it that can be detected with a 'sniffer', very sensitive for tiny leaks.

                          Quite right loads of cowboys around that seem to just gas up and away it goes. Funnily enough no F-Gas cert is required for the new R1234YF gas.

                            100% agree with you there

                              I’m in the trade (not car ac) and get scrutinised for every gram of refrigerant used and yet a chap from Halfords can just fire in a couple of hundred grams of 134a on the hope it’s not leaking. What a joke.
