Stay cool on the road with the Furrion Chill Cube® 18K RV AC unit. This in-depth guide covers everything you need to know about this powerful, efficient RV air conditioner.
When you're hitting the road in your RV, your air conditioner isn't just a comfort feature — it's a necessity. But many traditional RV AC units fall short when you need them the most. They’re noisy, inefficient, slow to cool down, and tough on batteries and generators. That’s where the Furrion Chill® Cube 18K RV AC unit stands out.
This next-generation rooftop air conditioner is engineered from the ground up to solve the most common pain points RVers face — and exceed expectations in both performance and ease of use. Not only is it the smallest RV air conditioner, it’s also one of the most powerful! Whether you're camping in a scorching desert, onshore at a lakeside retreat, or boondocking off-grid, the Chill Cube 18K is ready for the challenge.
Let’s break down everything you need to know — from cooling power to installation — so you can feel confident choosing and setting up this high-efficiency RV AC.
Why Traditional RV ACs Miss the Mark
Before we dive into the features of the Chill Cube, let’s look at the issues that plague conventional RV air conditioners — and why the Chill Cube is designed to overcome them:
- Power consumption: Most ACs are power-hungry and inefficient, often draining your batteries or overloading your generator.
- Noise levels: Loud compressors and constant cycling disrupt sleep and relaxation.
- Slow cooling: Many RVers complain that their units take too long to cool their space, especially in extreme heat.
- Uneven airflow: Some spots in your camper become chilly while others stay warm.
- Complex installs: Replacing or installing a unit often requires professional help or hours of frustrating work.
The Chill Cube 18K addresses all of these head-on and then some.
About the Furrion Chill Cube 18K
The Chill Cube 18K is a powerful, variable speed rooftop air conditioner designed specifically for RVs. It’s the first RV rooftop unit to deliver over one ton of cooling power — even when the outside temperature exceeds 105°F — using up to 40% less power than standard ACs.
Available in ducted and non-ducted configurations, the Chill Cube is adaptable to different RV setups and comes in black or white, giving you flexibility in both performance and style.
High-Efficiency RV Cooling Performance
At the heart of the Chill Cube is its variable speed compressor, which is a major upgrade from traditional fixed-speed units. This smart compressor dynamically adjusts to changing climate conditions and cooling demands. That means:
- Faster cool-down: The Turbo Cool mode kicks into high gear to rapidly bring your interior temperature down.
- Consistent comfort: The compressor doesn’t cycle on and off like a traditional unit. Instead, it ramps up and down gradually, maintaining steady temps and reducing humidity.
- Superior off-grid performance: The Chill Cube operates efficiently on a 2000W generator or inverter, making it ideal for off-grid campers.
- No need for a soft start: With a start-up current under 5 amps, the Chill Cube won’t trip your circuit breaker or require costly aftermarket soft start devices.
In short, it works better when it’s hotter — exactly when you need it the most.
Quiet, Continuous Operation
One of the standout features of the Chill Cube is its whisper-quiet performance. Traditional RV ACs start and stop abruptly, creating a constant symphony of loud cycling, clunky compressors, and high amp draw.
The Chill Cube changes that with:
- Smooth, variable speed operation that eliminates harsh on/off cycling
- Quiet ramp-up that keeps amp draw low and noise levels even lower
Even when it’s running at low speeds, the unit continues to dehumidify efficiently, keeping your cabin dry and comfortable. This is especially helpful in humid climates, where ACs often "cool" the air but leave everything feeling damp and sticky.
Compact Design, Smart Airflow
When it comes to size and airflow, the Chill Cube is ahead of the curve.
Aerodynamic Rooftop Unit
- Weighs only 72.4 lbs — about 10% lighter than standard RV ACs, making it the smallest RV air conditioner
- Sleek, low-profile design reduces drag for better fuel economy
- Leaves more room for solar panels, pop tops, and other rooftop accessories
Low-Profile Air Distribution Box (ADB)
For non-ducted installations, the ADB includes:
- A motorized oscillating vent that improves airflow throughout your cabin
- A wide-span louver system that distributes cool air more evenly, reducing hot spots
- Easy-to-use controls built directly into the ADB, including temperature and fan speed buttons, as well as a swing button for controlling the oscillating louver
Smart, Intuitive Controls
Controlling the Chill Cube is a breeze thanks to its intelligent onboard interface and included remote control. The system is packed with convenient modes and features:
- Power button: Turns the unit on and off
- Mode button: Switches between cooling, fan-only, and dehumidifier settings
- Eco/Gear button: Reduces power consumption to 75% or 50%
- Fan button: Lets you choose between auto, low, medium, high, and turbo
- Temperature control: Fine-tunes your comfort with simple up/down arrows
- Sleep button: Optimizes energy use and sound levels overnight
- Swing button: Activates the oscillating vent (non-ducted models only)
The Chill Cube also includes Follow Me mode, which turns the remote into a portable thermostat. When activated, the system will adjust based on the temperature near the remote — within a 26-foot line of sight — rather than relying solely on the temp at the ceiling. This allows you to more accurately target your ideal comfort level.
Easy, DIY-Friendly AC Installation
If you’ve been intimidated by RV AC installs in the past, you’ll be pleasantly surprised by how simple the Chill Cube is to set up. Designed for DIYers and professionals alike, the system requires just two main components: the rooftop unit and the air distribution box, or ADB.
