OEM Goodman Horizontal Drain Pan for ARPF364216AB — B1756028L

Goodman B1756028L Horizontal Drain Pan

The B1756028L is a genuine OEM horizontal condensate drain pan built for Goodman ARPF364216AB air handlers installed in horizontal (attic or crawlspace) orientation. In a horizontal setup the coil sits on its side, so condensate must be captured along the length of the coil — this purpose-built pan does exactly that, directing water to the drain connection instead of pooling inside the cabinet. Factory tooling ensures the mounting points and drain outlet match the original part precisely.

OEM vs. Generic

Horizontal pans are highly application-specific, and generic substitutes rarely match the slope and drain placement needed to keep an attic unit from overflowing. The genuine Goodman B1756028L removes that risk with a guaranteed factory fit, helping prevent ceiling water damage from a misaligned aftermarket pan.

Installation Difficulty

Moderate to advanced. Horizontal pan replacement usually means sliding the coil out, swapping the pan, and re-sealing the drain line — often in a tight attic space. Plan 45–90 minutes. A licensed HVAC technician is recommended if coil removal or refrigerant lines are involved.
