As HVAC professional, David Collins, explains, the HVAC industry has completely changed in the last 5 years. One major change is the refrigerants that are used. New refrigerants are being used that have zero ozone depletion and low global warming potential. In 1987, the Montreal Protocol was signed, which was the beginning of the movement to save the ozone layer. Since then there has been a continue effort to create refrigerants that do not deplete ozone and also have low global warming effect. The problem is that those new refrigerants are very flamable, which changes the whole way HVAC units work. Modern HVAC is a fascinating field and you're not going to find many people more knowledgable than David, so give it a watch! You will definitely learn something.
