Furrion Chill Cube 18k BTU RV Rooftop Air Conditioner - Quiet

In this review of the Furrion Chill Cube 18K rooftop air conditioner, the bottom line is simple: it is for RV owners and campervan travelers who want powerful, quiet cooling with improved efficiency and easier installation. The Chill Cube stands out because its variable speed compressors deliver consistent cooling without the abrupt starts and stops of single-speed units, which reduces noise and energy spikes; that continuous operation is the single biggest reason many owners will choose it for hot climates or extended off-grid use. This review focuses on real-world benefits like cooling speed, noise, install simplicity, and runtime.

Key Features

• Variable speed compressors: Changes speed to match cooling demand, providing steady temperature control and reducing the on/off cycling that wastes energy.
• High cooling capacity: Provides roughly one ton of cooling power, so it cools an RV quickly even in very hot ambient conditions up to 105F.
• Quiet operation: Continuous compressor operation and refined design reduce abrupt starts and stops, making the unit noticeably quieter inside the camper.
• Lightweight, compact design: At about 72.4 lbs the unit is roughly 10% lighter than comparable models, helping lower rooftop weight and reduce drag while driving.
• Easy to install: Bolt-on installation with a clear step-by-step guide simplifies fitting the AC to standard rooftop openings when paired with the separately sold ADB kit.
• Energy efficient refrigerant: Uses R32 refrigerant and efficient operation to extend battery runtime during off-grid or boondocking trips.

Who It's For

The Chill Cube is aimed at owners of campervans, travel trailers and small motorhomes who need robust cooling without compromising quietness or energy use. It fits drivers who value longer battery runtime for off-grid camping and those who want a lighter rooftop unit to help overall vehicle performance.

It is less appropriate for buyers who need a fully ducted multi-zone system or who expect a packaged installation with all mounting components included, since this listing is the AC unit only and the ADB and mounting kit are sold separately. Those users should plan for the additional parts and professional fitment if needed.

Pros & Cons

Pros

• Efficient variable speed compressor delivers steady cooling and improved energy use.
• High capacity cools quickly in hot conditions while running quieter than many single-speed units.
• Lightweight aerodynamic housing reduces rooftop drag and helps overall RV fuel economy.
• Clear bolt-on installation guide makes it approachable for owners comfortable with rooftop work.

Cons

• Control panel or remote control has some customer-reported issues, so buyers may need to verify controls meet their expectations.
• This is the AC unit only; the ADB and full install kit are sold separately and add to total cost and installation time.

Our Verdict

The Furrion Chill Cube 18K is a strong choice for RV owners who want fast, quiet cooling and better energy efficiency for off-grid use. It offers meaningful advantages over single-speed units thanks to its variable speed compressors and lighter aerodynamic design, but buyers should plan for the separately sold ADB installation kit and confirm the control interface meets their preferences. Overall it is good value for those prioritizing performance and runtime in hot conditions.

Frequently Asked Questions

Does this unit come with installation hardware?
The listing is for the AC unit only; the air distribution box and full kit are sold separately and are required for a complete rooftop installation.

How noisy is the Chill Cube?
Customers report noticeably quieter operation compared with single-speed RV ACs because the variable speed compressor avoids abrupt starts and stops.

Is it suitable for off-grid use?
Yes, the efficient variable speed operation and R32 refrigerant help reduce energy draw and extend battery runtime during off-grid camping.
