No I'm saying car A/C systems harbour bacteria that you subsequently breath in, in reply to your quote, that its just another motor industry rip off.
I had to do quite an extensive course to become a refrigerant handler and invest several thousands of pounds into the equipment, so I do speak...
Not really, but not a million miles away....we're in Horsham.
As for the A/C not working, no idea without looking, but it sounds like it's probably a leak, have you had it regased ? If there's a leak a nitrogen test will be the easiest way to locate it.
As much as I hate to admit it..... as I hate main stealers with a passion, they are quite correct.......ever got into a car and when it starts it has an eggy/ musty smell ? That's caused by bacteria, a lot of people don't even notice it as they are used to it, until its regased and they say it...
Anyone that's let's the gas out into the atmosphere is breaking the law, and can even go to prison (unlikely) if caught.
A reputable A/C engineer will always remove the old gas into a machine and recycle it.
I own a garage, I believe the industry recommendations is a regas every 2 years.
Make sure it is a regas and not a top up, lots of garages just pop in a bit more gas, where a decent garage take all the old stuff out and renew it, along with new oil and if they're really professional add some UV...
