Where's My Model Number?

Model and serial numbers for Coleman®-Mach® rooftop air conditioners can be found in two different places on each unit.

There are separate model and serial numbers for the rooftop unit and the various ceiling assemblies available. Both numbers can be helpful when troubleshooting air conditioning problems.

The ceiling assembly model and serial numbers may be located by removing the plastic grille covering the ceiling assembly. The model number sticker is located on the metal framework above the grille.
