A/C leak detection

[zack-cat]

So I was just thinking about trying to get everything rounded up for A/C season coming up and was wondering what everyone else uses to pin point leaks. I've been using nitrogen for the last few years but wonder if there's any thing easier or is nitrogen the best way to go?

Nitro and soapy water if the system is empty. For a system with refrigerant I use an inficon sniffer. http://products.inficon.com/en-us/n...c4add8?path=Products/pg-ServiceToolsforHVAC-R
Id say though I use the nitro 90% of the time although the sniffer finds leak quite quickly
