Dometic FreshJet Ceiling Assembly for Multi Zone Installations

What is a Dometic FreshJet ceiling assembly and when do I need one?

The ceiling assembly is the interior-side housing that mounts to the bottom of a FreshJet rooftop air conditioner and handles air distribution, control, and the seal between the AC and your RV ceiling. You need one if you are doing a brand new FreshJet installation, converting a single-zone setup to multi-zone control, or replacing a damaged or non-functional assembly. This collection covers the multi-zone variant used when a CCS (Climate Control System) thermostat controls more than one FreshJet unit on the same RV. For non-ducted single-thermostat builds, see the Dometic Ceiling Assembly for Non-Ducted Installations with Wall Thermostat collection instead.

Will this fit a Dometic FreshJet 3 or only the newer FreshJet models?

These multi-zone ceiling assemblies are designed for the current FreshJet platform, which includes FreshJet 3 control box configurations as well as the FreshJet 7 series rooftop units. Before ordering, confirm the model and serial number on your rooftop AC and verify that your installation is wired for CCS multi-zone control rather than a standalone wall thermostat. If your build uses a heat pump variant with non-ducted distribution, the FreshJet 5 With Heat Pump Ceiling Assembly for Non-Ducted Installations is the correct match.

Is this assembly ducted or non-ducted?

This collection covers the ducted multi-zone configuration, meaning conditioned air is routed through your RV's overhead duct system rather than dumped directly into the cabin from the ceiling grille. If you are running a Coleman rooftop unit on a ducted coach, the Coleman Ceiling Assembly for Ducted Installations collection covers that platform. Always match the assembly type to your roof unit and your coach's duct layout before installing.

How much does a complete FreshJet multi-zone install cost?

Pricing depends on how many zones you are controlling and which components you already have on the roof. A multi-zone ceiling assembly is one line item; you will also need the rooftop FreshJet unit, the CCS thermostat, and any zone dampers or distribution boxes for ducted runs. Individual prices for each ceiling assembly variant are listed on the product pages in this collection.
