The cannisters cost around £50 with the adapter, and they do not tell you how much refridgerant is in your system and you could overfill, which will cause failure.

It is also cheaper to use staykool than buy a refill kit.
Yes we can deodorise your cars evaporator killing all the bacteria and moulds that occur. We do not use the cannister spray bombs that most people use, these only mask the problem. We inject a special spray down to the evaporator which kills the odour at source. and leaves a very pleasant odour instead.
