Even as recently as last year, the system manufacturers themselves, though pleased with the new refrigerant’s efficiencies, were hesitant to comment on how contractors were adapting. This year they are speaking out, and the news is good. Training is helping contractors feel confident about products using this relatively new refrigerant and is keeping the number of returns to a minimum.
One of the main indicators comes from compressor manufacturers, whose products are returned under warranty for problems that more often relate to causes such as poor installations and/or poor diagnostics, rather than an actual problem with the compressor.
