Hi Guys, has anyone tried or had success with the DIY aircon top up kits they sell in Halfords? http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogI...
It promises that each can gives three top ups and considering the kit is the cost of just one top up in the garage it seems good value (if it works)

I paid approx £74 to have full service as my air con had gradually lost effectiveness. Within 2 weeks of the sevice it failed completely due to a leak in the condenser that was probably the cause of the pre service gradual decline. The lead was invisibly at the time of service even with UV flourescent dye.
I would be inclined see if you can find someone who will put in a bit of dye, oil and and top up pressure as cheap as possible and compare this with Halfords. No point a full service if its going to leak out again.
Cheers
