OEM vs. Generic

The OEM B1756020L matches the original footprint, drain-outlet location, and pan slope exactly. Generic universal pans of approximate size often sit incorrectly, leaving the coil drip edge off the pan and causing leaks. Choosing the factory part ensures proper drainage and a leak-free seal.

Installation Difficulty

Moderate. Vertical pan replacement involves accessing the coil compartment and reseating the coil onto the pan. Plan 30–45 minutes; a licensed HVAC technician is recommended.
