I had my Air con serviced today, I went to Kwik-Fit to have my front wheels re-balanced and they do this Air con recharge.
The deal is, they will improve your Air con by 10% or you don't pay.
To do this, they totally drain your Air con of gas (this takes ages), then they reload it.
They take temperature readings before and after and based on that, decide if you pay. Before mine was 6.1 degrees, after it was 5.5.
It was a close call and he had to leave it running ages to get it down that low ......
So they charged me half. It cost me £33 including having my wheels balanced.
I cannot reccommend them enough for this service in particular, and frankly I'm more surprised at that statement than anyone!
