Features & Specifications
18,000 BTU cooling capacity — Powerful enough for most Class A, B, and C RVs
Variable speed compressor (30%–100%) — Adjusts output continuously for precise temperature control and energy savings
Integrated heat pump — Provides warmth down to 45°F ambient temperature, eliminating the need for a separate heater
R32 refrigerant — 20% more efficient than traditional R410A with significantly lower global warming potential
Ducted air distribution — Evenly cools and heats your entire RV interior through existing ductwork
Whisper-quiet operation — As low as 55 dB for peaceful camping and sleeping
Corrosion-resistant housing — Sealed electrical components engineered to withstand road vibrations and weather extremes
Why Choose the Furrion® Chill® Cube 18K BTU?
Traditional single-speed RV air conditioners cycle on and off constantly, creating temperature swings, wasting energy, and wearing out components faster. The Furrion® Chill® Cube variable speed compressor runs continuously at the exact output needed — maintaining precise temperatures while consuming less power. That means fewer generator runs at campgrounds and longer battery life when boondocking.
The integrated heat pump adds year-round versatility that most rooftop units simply can't match. Whether you're camping in summer heat or shoulder-season cool, this single unit handles both — no separate propane heater required. The Furrion® Chill® Cube 18,000 BTU is the most capable rooftop climate system Furrion® offers in this class.

Helpful Tip: For RVs over 35 ft or with poor insulation, the 18,000 BTU variable speed model is the best choice. For smaller rigs or height-restricted campgrounds, consider the low-profile 15K BTU option.
Lippert-Published Performance Details
Lippert has now published additional Chill Cube 18K details that help explain why this unit is different from a standard RV rooftop AC. The key updates are stronger efficiency language, clearer high-heat performance claims, and more detail on the variable-speed compressor behavior.
Extreme-heat cooling: Lippert says the Chill Cube 18K is built to keep cooling in outside temperatures over 105°F.
Lower power draw: Lippert describes the system as requiring up to 40% less power than a typical RV air conditioner while still delivering over one ton of cooling.
No aftermarket soft start needed in most installs: the variable-speed compressor ramps up gradually instead of pulling a hard startup surge, giving better generator flexibility and helping avoid nuisance breaker trips.
Continuous, quieter operation: instead of loud on/off cycling, the compressor changes speed based on cooling demand for steadier temperature control and lower operating noise.
Better humidity control: because the compressor can keep running at lower speeds, it continues pulling clammy air out instead of short-cycling.
Road-ready roof profile: Lippert calls out the aerodynamic rooftop design, reduced wind drag, and extra roof space for solar panels or pop-top layouts.
Ducted airflow: designed to feed the RV’s existing duct system for more even whole-coach distribution.
R32 refrigerant note: Lippert notes that R410A equipment may be replaced with R32-designed components, but R32 refrigerant cannot be used in R410A-based air conditioners. Always match replacement components to the refrigerant type listed on the RV air-conditioning equipment.
What size RV is the Furrion® Chill® Cube 18,000 BTU designed for?
The 18,000 BTU model is ideal for Class A, B, and C motorhomes and travel trailers over 25 ft. For RVs under 25 ft, the 15K BTU HE model may be sufficient and more energy-efficient.
Is this compatible with my existing RV roof opening?
Yes — the Furrion® Chill® Cube fits the standard 14" x 14" RV roof opening used by most manufacturers. Always verify your roof opening dimensions before ordering.
How does the variable speed compressor save energy?
Unlike single-speed units that run at 100% or shut off completely, the variable speed compressor modulates between 30%–100% output. This means it runs continuously at the lowest power needed to maintain your set temperature — reducing energy consumption by up to 30% compared to traditional units.
Does this unit work as a heater?
Yes — the integrated heat pump provides up to 12,000 BTU of heating capacity and operates effectively down to 45°F ambient temperature. Below that threshold, a supplemental propane or electric heater is recommended.
How do I install the Furrion® Chill® Cube on my RV?
Installation follows the same process as most rooftop RV AC units — remove the old unit, clean the roof opening, set the new unit in place, connect the ducting and electrical, and secure with the included hardware. Professional installation is recommended if you're not comfortable working on your RV roof.
What refrigerant does the Furrion® Chill® Cube use?
This unit uses R32 refrigerant, which is approximately 20% more efficient than the older R410A standard and has a significantly lower global warming potential (GWP of 675 vs. 2,088 for R410A).

What's the difference between ducted and non-ducted rv ac units? Ducted systems distribute air through ceiling vents for more even temperature control throughout your RV, while non-ducted units blow air directly from the unit location.
Can this unit run on solar power? While more efficient than traditional RV AC units, the Chill® Cube still requires significant power. You would need a substantial solar array and battery bank to run it consistently off-grid.
How does the heat pump compare to electric heat strips? Heat pumps are 2-3 times more energy efficient than electric resistance heating, though they become less effective below 45°F ambient temperature.
Is professional installation required? While technically possible to self-install, we recommend professional installation to ensure proper sealing, electrical connections, and ductwork integration.
