Coleman-Mach 9630-725 Non-Ducted Bluetooth Ceiling Assembly

The Coleman-Mach 9630-725 is the ceiling assembly that turns a rooftop unit into a finished, controllable system inside your RV. On a non-ducted rig, this is the box that mounts to the ceiling right under the air conditioner or heat pump. It pulls return air through the filter, pushes conditioned air back out through the louvers, and it's where all the controls live. Heat and cool control both sit right on the assembly, so you set your temperature and mode from the ceiling instead of hunting for a separate wall thermostat.

What sets this one apart is the Bluetooth. The module is FCC certified and pairs with the Coleman-Mach app, so you can run the unit straight from your phone. Set the temperature from the couch. From bed. From the picnic table outside while the coach cools down before you climb back in. It's Smart Technology compatible too, so it drops into Coleman's connected setup if you're running one. And it all runs on 12 volt DC, the same house power as the rest of your low-voltage system.

This assembly fits the standard 14 inch by 14 inch roof vent opening, which is exactly the size Coleman-Mach rooftop units drop into. It's built for heat pump and heat-ready rooftop units, so if your coach came with a Coleman heat pump or a heat-ready air conditioner up top, this is the ceiling half that matches it. Non-ducted means the conditioned air comes straight out of this assembly into your living space instead of running through ceiling ductwork. That's the common layout on single-zone travel trailers and a lot of smaller fifth wheels.

Most folks land here because the original ceiling assembly finally gave out. The old thermostats crack, the louvers snap off, or the control quits and you're left running the AC with no real way to set it. The good news is that swapping the ceiling assembly is one of the friendlier RV air conditioner jobs. You're working from inside on a step ladder, not up on the roof in the sun. Kill the 12 volt power, drop the old assembly, transfer the wiring over, and seat the new one against the ceiling gasket. If you've done any 12V work in a coach before, you can knock this out in an afternoon.

The louvers are built to spread air where you actually need it instead of dumping it all in one corner of the cabin. That matters on a non-ducted rig, because you don't have ductwork to even the temperature out room to room. Return air pulls through the filter housed in the assembly, so keep that filter clean. A clean filter lets the unit breathe, cool faster, and pull less current doing it.

The digital readout keeps things simple. You get your set temperature and mode right there on the display, no guessing. Between the on-board control, the digital readout, and the phone app, you've got three ways to run the same unit, which is handy when someone's already comfortable in bed and doesn't want to get up to bump the temperature.

One more thing worth knowing if you've got a heat pump up top. A heat pump gives you efficient warmth in the shoulder seasons without leaning on the propane furnace, and this assembly is the piece that lets you run that heat from the same control you use for cooling. Flip from cool to heat right on the assembly or in the app. In spring and fall, that's often all the heat a coach needs to stay comfortable overnight.

A couple of honest notes before you order. This is the ceiling assembly only. It is not the rooftop unit itself, so you still need a working Coleman-Mach air conditioner or heat pump up top for this to do its job. And it's built specifically for the Coleman non-ducted system, so confirm your coach is running a non-ducted setup before you buy. If your rig sends air through ceiling ducts, that's a different assembly. Match this one to your existing rooftop unit and your heat-and-cool control is back in business.
