Getting your A2L certification? Practice with exam-style questions on R-454B and R-32 safety, then keep the field tools you'll use once you're carrying the card. Many distributors and manufacturers now ask for an A2L / Low GWP refrigerant safety card before they'll sell you equipment. This app is the study half and the gauge half in one download — free, offline, no account. PRACTICE MODE • 300+ original questions across 11 topics: A2L characteristics and ASHRAE 34 classes, flammability metrics and GWP, codes and regulations, A2L tools, handling and transport, leak detection and mitigation, recovery and evacuation, servicing and charging, installation and charge limits, emergency procedures, retrofit and transition • Quick 10, single-topic drills, and a 50-question mock exam with an optional 35-minute timer • Every answer comes with an explanation. Math questions are solved by the same engine as the calculators, so the numbers are correct by construction • Score by topic, review every miss, and track your accuracy over time — all stored on your phone • Above / below 70% shown for orientation; your test provider's passing score governs WHO IT'S FOR Technicians sitting a Low GWP / A2L safety exam (closed-book and open-book formats cover the same material), HVACR program students, and contractors whose distributor now asks for the card.
