Coleman Mach Bluetooth Non-Ducted Ceiling Assembly, 9430-720

The Coleman Mach Bluetooth ceiling assembly is the interior half of a non-ducted rooftop air conditioning setup. If you've got a cool-only Coleman rooftop unit sitting up top and you're running it as a non-ducted system, this is the piece that lives on the inside of your RV ceiling. It handles the air discharge, houses the controls, and gives you a clean digital readout right where you can reach it.

Non-ducted is the simple, direct approach. Instead of pushing conditioned air through a network of ceiling ducts, the assembly discharges cold air straight into the living space from the unit itself. That means fewer places for airflow to get lost, and it's the setup you'll find on a lot of single-zone campers, travel trailers, and smaller motorhomes. This assembly fits the standard 14 inch by 14 inch vent opening, so it drops into the same hole the factory unit used.

The headline feature here is Bluetooth. The controls are built right onto the assembly with a digital readout, so you can set your temperature at the ceiling the old-fashioned way. But you can also pair it wirelessly and run the cooling from your phone. It's Smart Technology compatible, which is Coleman's way of letting you manage the unit without getting up off the couch or climbing a ladder. Set it, forget it, adjust it from across the rig.

A couple of things to be clear about. This is a cool-only control assembly. It's built for Coleman rooftop units that cool and don't heat, so if your setup includes a heat strip or heat pump you'll want the matching assembly for that configuration instead. And it's the ceiling assembly, not the whole rooftop unit. It pairs with the compressor unit already mounted on your roof.

Power is 12 volt DC, which is exactly what you'd expect from an RV control circuit. It runs off the same low-voltage side that feeds the rest of your rooftop unit's controls, so wiring it in is a straightforward job for anyone comfortable working around an RV roof AC. The assembly is FCC certified for its wireless hardware, so the Bluetooth radio is a legitimate, compliant piece, not an aftermarket add-on.

Who's this for? Owners replacing a tired or non-working ceiling assembly on an existing Coleman cool-only rooftop unit, and folks who want to add wireless control to a rig that came with a basic manual ceiling assembly. If your current setup is a plain knob-and-louver assembly and you're tired of it, stepping up to the Bluetooth version is a real quality-of-life upgrade. You keep the rooftop unit you already own and just swap the part you actually touch every day.

The digital readout is a nice touch on a category that spent years stuck with a slider and a dial. You get an actual temperature number instead of guessing where the middle setting lands, and the controls sit on the assembly face where they're easy to read from the floor. For anyone who's squinted at a foggy analog control on a hot afternoon, that clarity alone is worth the swap.

Installation is a swap, not a project. Kill the power, drop the old ceiling assembly, land the wiring on the new one, and set it into the same 14 by 14 opening. Pair it once and you're done. Just keep in mind what shows up at your door is the ceiling assembly itself, the part that mounts to the interior ceiling and carries the controls and the Bluetooth hardware. Your rooftop compressor unit and any wiring beyond what the assembly needs are separate. We always recommend confirming your rooftop unit is a cool-only Coleman model before ordering, because matching the assembly to the unit is what keeps everything talking correctly.
