It is used in a new generation of \u003cstrong\u003ecentral heat pumps\u003c\/strong\u003e and air conditioners designed for this refrigerant.

The EPA places it in class \u003cstrong\u003eA2L\u003c\/strong\u003e of the ASHRAE 34 standard: low toxicity and low flammability. It requires tools, recovery equipment and methods designed for A2L refrigerants.\u003c\/p\u003e\n\u003ch3\u003eGood charging practice\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCheck the \u003cstrong\u003enameplate\u003c\/strong\u003e: R-454B goes only into equipment designed for it, never as a replacement for R-410A.\u003c\/li\u003e\n\u003cli\u003eAs with any blend, charging is usually done in the \u003cstrong\u003eliquid phase\u003c\/strong\u003e, to keep the blend’s proportions: follow the manufacturer’s instructions.\u003c\/li\u003e\n\u003cli\u003eWeigh the charge on a scale, after a leak check and evacuation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSale limited to certificate holders\u003c\/h3\u003e\n\u003cp\u003eIn Québec, the \u003cstrong\u003eRèglement sur les halocarbures\u003c\/strong\u003e (Q-2, r. 29) governs this refrigerant. Its section 51 requires anyone who sells halocarbons to make sure the buyer holds an \u003cstrong\u003eenvironmental qualification certificate for workers\u003c\/strong\u003e, or employs a person who holds this certificate. Its section 43 also reserves the charging, maintenance and repair of air conditioning and refrigeration equipment to qualified persons. We therefore check the certificate before every sale. Without a certificate, leave the charging to our refrigeration technicians.\u003c\/p\u003e\n\u003cp\u003eThe safety data sheet is supplied with the cylinder by its manufacturer.\u003c\/p\u003e\n\u003ch2\u003eAvailable from AirGreen, with or without installation\u003c\/h2\u003e\n\u003cp\u003eAirGreen sells R-454B to refrigeration technicians and qualified companies, and our technicians charge it on site in \u003cstrong\u003eMontréal\u003c\/strong\u003e, \u003cstrong\u003eLaval\u003c\/strong\u003e, \u003cstrong\u003eLongueuil\u003c\/strong\u003e, on the \u003cstrong\u003eSouth Shore\u003c\/strong\u003e and on the \u003cstrong\u003eNorth Shore\u003c\/strong\u003e.
