I've seen a R-12 to R134A conversion kit, which contains new refrigerant,
a can of oil, adapters, and hoses, BUT...

Don't we need to have someone evacuate the system and flush it before
using this kit? Or can I just put the new stuff in?

Caveat: My system is drained of R-12 over the last couple of years,
slowly getting warmer--unfortunately, I don't use it much--I should have
turned it on every 2 weeks like I think Joel recommended once....

Opinions? BTW, I won't vent any leftover R-12 into the air, so that's not
an option.
