Yes, modern Carrier central air conditioning condensing units and indoor evaporator coils frequently utilize all-aluminum coil designs (such as their patented WeatherMaker and MicroChannel coils) instead of traditional copper-tube and aluminum-fin configurations. All-aluminum coils offer superior resistance to formicary corrosion—a chemical breakdown that historically caused refrigerant leaks in copper tubing—while improving thermal heat transfer efficiency, reducing system weight, and maintaining structural durability across seasonal cycles.
