Mach 8 Coleman Ceiling Assembly for Ducted Installations

What is the Coleman Mach 8 ceiling assembly used for?

The Mach 8 ceiling assembly is the interior-side component that finishes a ducted Coleman Mach 8 air conditioner installation. It mounts to the RV ceiling below the rooftop unit, routes cooled air into your existing duct system, and houses the return air filter and control interface. This collection covers the parts needed to complete or service a ducted Mach 8 setup.

How do I know if I have a ducted or non-ducted Mach 8 setup?

A ducted system pushes air through registers built into your RV ceiling, with the ceiling assembly acting as a return-air grille. A non-ducted system blows air directly out of the ceiling assembly into the living area. If you see vents in other parts of your ceiling tied back to the AC, you have a ducted unit. For non-ducted Coleman alternatives, see the Coleman Power Saver HP ceiling assembly options.

Will this ceiling assembly fit my Coleman Mach 8 rooftop unit?

These ceiling assemblies are designed specifically for Coleman Mach 8 low-profile rooftop units in ducted RV installations. Confirm your rooftop unit model number before ordering to make sure you get the correct fit. If you also need to reduce startup load on the compressor, pair the install with a Coleman RV air conditioner soft start kit.

Do I need any other parts to complete the installation?

A complete ducted Mach 8 install typically requires the rooftop unit, the ceiling assembly, a roof gasket, and the correct thermostat or control board. Check that your duct openings are sealed and your roof gasket is uncompressed before final assembly. Need help confirming fitment?
