The HVACR industry is in the process of transitioning away from HFCs such as R-410A to alternative refrigerants that are mildly flammable (A2L). Because of their flammable nature, these refrigerants are referred to in terms that may not be familiar to contractors and technicians.

As the HVACR industry transitions away from HFCs such as R-410A to alternative refrigerants that are mildly flammable (A2L), it is not surprising that those who will be handling – or teaching about -- these new products have a lot of questions.

Unlike the last transition, which shifted from the use of one nonflammable refrigerant to another, many of these new refrigerants are mildly flammable (A2L), so additional training will be needed in order to safely use them.

Transitioning to low-GWP refrigerants doesn’t mean compromising on safety.

As the refrigerant transition occurs, safety standards and building codes must be updated.

Now the industry is moving to low-GWP HFCs, additional training will be needed in order to safely use these refrigerants.

Change is coming once again to the HVACR industry, as there is a growing movement to transition from R-410A to lower-GWP refrigerants.
