The problem:

From the factory, RV A/C units aren’t directly connected to your vents. Instead, they dump cold air into a hollow ceiling space (the plenum) and hope it finds its way to the ducts.

Air swirls and escapes inside the plenum
You lose air pressure
You lose cooling efficiency

That’s why your vents often feel weak, even when your A/C is running at full power. From the factory, RV A/C units aren’t directly connected to your vents. Instead, they dump cold air into a hollow ceiling space (the plenum) and hope it finds its way to the ducts.

Works on the Dometic, Coleman, Furrion, and others. Increases airflow, whisper quiet RV A/C Mod. Requires ducts, non-ducted A/C are not supported.

Unmatched Vent Compatibility
Unlike other systems who limit their designs, every vent size is supported.

No Plenum Insertion Required

Unlike systems that must be inserted into the A/C unit’s return or output path, this splitter is installed externally, with no need to modify or penetrate the HVAC housing. That means:

Cleaner install
No interference with A/C return airflow
No internal couplings or fluid transfer

Only brand on the market for Single Vent solutions and Angled splitters for tight spaces

What vent size to order?

Measure your vent openings. To measure remove the AC cover, air filter. Pay close attention to the power box and any connecting wires careful to not pull on anything or put tension on temp monitor wires.

Remove the screws holding the filter assembly on.

Measure your vents

Partial Brim vs Normal Brim Vs Short Depth?

For models with vents less than 6″ away from the cold output, select “Short Depth”

While you wait for your order:

Seal any opening, gap, hole, etc that could let cold air or hot air not be directed properly.
