RevNitro on Instagram: "Why did old car AC feel like a freezer? ❄️ Simple: Older cars used R12 refrigerant, which cooled extremely fast and was super powerful. But R12 was banned worldwide for damaging the ozone layer. Modern cars use R134a or R1234yf, which are eco-friendly but not as strong. Plus, new cars have smaller compressors, more glass area, and lightweight bodies — so the cooling feels less powerful. #CarAC #R12 #CarFacts"
