OEM vs. Generic

This is the factory OEM pan, molded to the exact drain-port locations and mounting profile of your unit. Generic universal pans often require trimming, re-drilling, or sealant to seat correctly and can leave gaps that lead to leaks. Choosing OEM guarantees a leak-free, drop-in fit and preserves any remaining manufacturer warranty.

Why Replace a Drain Pan

Cracked, warped, or rusted pans are a leading cause of ceiling stains and water-sensor shutdowns. Replacing the pan during routine service restores proper condensate flow and protects the coil and blower assembly below.

Installation Difficulty: Moderate

Installation requires removing the coil access panel and sliding the old pan out, then seating the new pan and reconnecting the drain line. Most technicians complete the job in 30–60 minutes. We recommend installation by a qualified HVAC professional and confirming a proper trap and slope on the condensate line.
