Both aluminum and copper coils can be used in air conditioning systems, and each material has its own advantages and disadvantages.
Aluminum coils are lighter in weight and less expensive than copper coils, making them a popular choice for manufacturers. They also have better corrosion resistance than copper, which can be important in areas with high humidity or salty air.
Copper coils, on the other hand, have better heat transfer properties than aluminum, which means they can more effectively cool the air in the system. They are also more durable than aluminum, which can be important in areas with harsh weather conditions or other environmental factors that can cause wear and tear on the system.
Ultimately, the choice between aluminum and copper coils will depend on a variety of factors, including the specific needs of the system and the preferences of the manufacturer or installer.
