Dometic Blizzard NXT Ceiling Assembly for Non-Ducted Installations with Wall Thermostat

What is the Dometic Blizzard NXT non-ducted ceiling assembly?

The non-ducted ceiling assembly is the interior component that mounts to the underside of your RV roof and works with the Blizzard NXT rooftop unit. This version routes conditioned air directly into the living space through the assembly's own grilles rather than through ductwork, and it pairs with a wall thermostat for temperature control instead of a built-in ceiling control. Confirm your rooftop unit model and your installation type (ducted vs non-ducted) before ordering.

Will this ceiling assembly work with my existing wall thermostat?

This assembly is built for use with a compatible Dometic wall thermostat rather than a ceiling-mounted control. If you are replacing a failed assembly, verify your current thermostat model and wiring at the rooftop unit. For a complete AC system replacement or upgrade path, see related options like the FreshJet 5 with Heat Pump non-ducted ceiling assembly or the Coleman Power Saver HP ducted ceiling assembly.

What is the difference between ducted and non-ducted ceiling assemblies?

A non-ducted assembly discharges cool air directly out of the ceiling unit into a single open area, which is typical in smaller travel trailers and pop-ups. A ducted assembly connects to your RV's overhead duct system to distribute air to multiple registers throughout a larger coach. The two are not interchangeable. Check your roof opening and existing duct layout before ordering, and if your rig is ducted, look at the Coleman Power Saver HP ducted ceiling assembly instead.

Is this assembly easy to install as a replacement?

Yes, for an owner comfortable with basic 12V and high-voltage AC wiring, swapping a non-ducted ceiling assembly is a manageable job. You will disconnect power, drop the old assembly from the bolts that join it to the rooftop unit, transfer the wiring per the included diagram, and lift the new assembly into place against the roof compression gasket. If you are also considering a soft start to reduce inrush current on the compressor, see the Coleman RV air conditioner soft start collection.

How do I confirm the correct part for my Blizzard NXT before ordering?

Pull the model and serial tag on your rooftop unit and match the Blizzard NXT model number, then confirm your installation is non-ducted and that you are running a wall thermostat. If you are unsure, text or call our team at 817-984-1852 with your rooftop model number and a photo of the current ceiling assembly and we will verify fit before you order.
