Why Choose the Furrion Chill Cube 18K BTU Variable Speed RV AC?

Standard single-speed RV air conditioners cycle on and off constantly — creating uncomfortable temperature swings, excessive amp draw, and premature wear. The Furrion Chill Cube variable speed compressor eliminates all of that by running continuously at precisely the output your RV needs. The result: consistent temperatures, quieter operation, and up to 50% less energy consumption.

At just 72.4 lbs. with an aerodynamic rooftop profile, the Furrion Chill Cube 18K BTU reduces wind drag and improves fuel economy on the road — while leaving valuable roof space for solar panels and pop tops. The R32 refrigerant system delivers superior cooling performance even when ambient temperatures reach 105°F, making it the ideal variable speed RV rooftop air conditioner for hot-climate camping.

The non-ducted design means straightforward installation and direct, powerful airflow into your RV's living space — no ductwork modifications needed. Whether you're a weekend warrior or a full-time RVer, this unit delivers the reliability and efficiency you demand.

Frequently Asked Questions

How do I install the Furrion Chill Cube 18K BTU rooftop air conditioner?

The FACR18VSSA-BL-AM uses a standard bolt-on rooftop mount and includes a complete step-by-step installation guide. No special tools are required beyond basic hand tools. Conversion kits are available if upgrading from a competitor's unit.

Is the Furrion Chill Cube 18K compatible with a 2000W generator?

Yes — the variable speed compressor is specifically engineered to run on a 2000W generator or inverter, making it ideal for boondocking and off-grid camping where generator capacity is limited.

What is the difference between ducted and non-ducted RV air conditioners?

Non-ducted units (like this model) deliver air directly into the RV's living space through a ceiling assembly — ideal for single-zone cooling. Ducted units distribute air through your RV's existing ductwork for multi-zone climate control throughout the entire coach.

Does the Furrion Chill Cube 18K need a soft start device?

No. Because the variable speed compressor starts gradually and adjusts continuously, it eliminates the high amp draw associated with single-speed compressor startups — making aftermarket soft start devices unnecessary.

What refrigerant does the FACR18VSSA-BL-AM use?

This unit uses R32 refrigerant, which is 20% more efficient than traditional R410A and has a significantly lower global warming potential (GWP), making it a more environmentally responsible choice.
