Green air conditioners for tropical Grenada?

The Carribean heat on Grenada and Carriacou makes air conditioners a popular addition to the home.

But the gas is highly flammable, meaning installation and maintenance require special knowledge and skills on the part of technicians, something they often lack — until now.
