On "A2L Mitigation for Refrigeration Systems"

A2L refrigerants are coming whether you like it or not, and the charge limits aren't the real problem—the compliance burden is. Leak detection, isolation valves, ventilation upgrades in tight mechanical rooms, longer inspection intervals: that's where your labor costs live, and most shop owners haven't priced that into their service calls or retrofit bids yet. You need to start figuring out which jobs actually pencil out under the new regs, because doing it wrong or cheap will cost you more in callbacks and liability than the refrigerant itself ever will.
