No, I don’t use sealant in my air conditioner systems. I think there is potential for it to gunk up and clog the system. If I have a leak I prefer to find it and repair it properly.
Since “sniffers” don’t work for hydrocarbons (although I have read there is a very expensive one available), I would suggest that if you think you have a leak, use nitrogen or regular compressed air to charge the system up to about 100 psi and then use a bubble solution on the outside. Use one made for detecting propane leaks. However, if there is a leak in the evaporator in the heater box you won’t see it unless you remove the cover of the box. A sniffer probably wouldn’t find that leak either.
