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.

Frequently Asked Questions

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).
