Stop in for a cup of coffee

I have a freon leak somewhere cant find it, weird it will hold a vac overnight though. Need to borrow a sniffer to find it one day.
Our Service Techs run into this all the time. Depending on the refrigerant (and costs), nitrogen and soap bubbles may be your best friend here.

But if you need/want to borrow a sniffer, shoot me a PM. I have two of them at home, and I don't foresee needing either of them for a while.
