I used my local Halfords service centre to do an MOT in March 17, and decided to use them to do an aircon service inc a deodorising treatment My local dealer wanted £125 plus vat, whereas halfords wanted £60inc. I have never had an AC service on any of the cars I have driven over the last 25yrs, as they were company cars which i usually had for 3-4yrs and never had any AC issues As my AC was taking time to get cold I decided that it needed doing. There was no problem with any leaks etc, but it was around 20-25% low on gas, and now works fine. I did, however, notice a film of a greasy substance all over the gloss black trim - centre console and glovebox and both front doors. I dread to think what I may have inhaled, as I drove the car around for an hour after it was done! is this normal and to be expected whenever any aircon treatment is applied, or should halfords have placed a cloth in front the vents to collect any residue when starting the system after? Took bloody ages to clean off, had to do the seats too! Won't be going there again!
