GT heat pump - evap coil pinhole leaks

AC,

Equipment (and brazing) is not the problem. Why buy R22 when dried and filtered propane is available?

I like Jeff's suggestion on charging it up to max and using soapy water to look for leaks. Cheap and visual . . . . and he is right - the R22 has to come out anyway . . .

Over the years I have heard technicians grumble that the sniffers do not find tiny leaks.

That way, I can scan the entire evaporator coil.

Thanks guys!

Steve
