Do Copper Coils Last Longer Than Aluminum in HVAC Systems?
Copper coils offer significantly longer lifespans than aluminum in most HVAC applications, justifying their higher initial cost. Copper’s physical stability ensures a service life of over 15 years, even in harsh coastal high-salt or industrial high-pollution environments—one coastal commercial complex’s copper-coil ACs showed no major corrosion after 18 years.
