Why Replace Your Collector Box Gasket?

Over time, heat cycling and condensation can degrade collector box gaskets, causing them to crack or lose their sealing ability. A compromised gasket can allow combustion byproducts to escape into the living space, creating a safety risk. Prompt replacement with a genuine Carrier OEM part ensures continued safe and efficient furnace operation.
