US Secretary of State John Kerry told delegates in Rwanda on Friday that HFCs were "disastrous for our climate".
The chemicals' molecules can trap heat from the Sun thousands of times times more effectively than carbon dioxide, a better-known driver of climate change.
Delegates worked through the night in the Rwandan capital, Kigali, to reach an agreement that would suit both developed and developing countries.
The use of air conditioning has been rising in emerging economies, pushing a 10-15% rise in the amount of HFCs being released into the atmosphere.
