Refrigerant Phasedown Quiz
Take the HVAC challenge quiz from Chemours and test your knowledge about future refrigerant changes and developments brought under the HFC phasedown.
How’s your understanding of HFC phasedown requirements and potential impacts to the HVAC industry? Do you know much about mildly flammable refrigerants (A2Ls) and their benefits? How will the transition affect your day-to-day service call routines?
Take our quiz now and learn more.
The real test of course is managing the changes through the phasedown.
You’ll have questions. Chemours has answers.
Some questions relate to content within this webinar.
