try 2 go into a hardware shop and purchase a can of isobutane or any other refridgerant, follow the instuctions on the reverse of can, These local engineer's just rip u off for a job any man can do !
Normally liquid ammonia NH3 does the job, Nh3 is hard to get and is usually in a pressurized container
