10 Best Rv Ac Units 2026 in the United States

The Furrion Chill Cube 18K BTU rooftop air conditioner is a solid choice for RV owners looking for powerful and efficient cooling. It offers strong cooling capacity at 18,000 BTUs (about 1.5 tons), which is enough to keep most campervans comfortable even in hot weather. Its variable speed compressor helps maintain a steady temperature quietly, around 50 decibels, so it won’t be too noisy inside your RV. The unit is also relatively energy-efficient with a SEER rating of 14 and a 4-star BEE rating, meaning it won’t drain your battery as quickly during off-grid trips.

Installation is straightforward with a simple bolt-on method, but keep in mind this package is just the AC unit—you’ll need to buy the adapter base separately to complete the setup. Weighing about 80.5 pounds, it is lighter than many other models, and its aerodynamic design helps reduce wind drag when driving. The non-ducted style means the cooled air is released directly into the RV interior, which works well in smaller spaces but might not be ideal if you want airflow distributed through vents.

It runs on 12V electric power and comes with a thermostat control for easy temperature adjustments. If you value a quieter, energy-conscious AC with good cooling power and don’t mind purchasing additional parts for installation, this Furrion Chill Cube can serve as a reliable upgrade for your RV.

The Furrion Chill Cube 18K BTU RV rooftop air conditioner is designed to deliver strong cooling power suitable for campervans and RVs needing efficient climate control. With 18,000 BTUs, it offers ample cooling capacity for medium-sized RVs. Its variable speed compressor helps it run quietly and steadily, avoiding the noisy start-stop cycles common in many RV units. This feature also boosts energy efficiency, extending battery life during off-grid use, which is a big plus for campers who rely on limited power sources.

The unit is lightweight (about 72 lbs) and has a low-profile aerodynamic design that reduces wind resistance, helping maintain better RV fuel efficiency. Installation is simplified through a bolt-on process and a clear guide, though the air distribution box (ADB) is sold separately, which adds to setup complexity and cost. Control is managed via button or touch controls, including modes like Turbo Cool and Silent Mode, giving users flexibility in managing comfort and noise levels. The unit uses the environmentally friendlier R32 refrigerant and holds a high 5-star energy efficiency rating, reflecting its power-saving design.

The AC unit requires additional parts for full installation, and its power consumption at 5118 watts may be on the higher side for smaller RV electrical systems. While it performs well in quiet operation, some users might find the installation more involved without the full accessory kit. This model suits RV owners prioritizing efficient, quiet cooling with good energy savings, especially if they are comfortable handling or paying for separate installation components.

The Furrion Chill Cube 18K is a powerful and efficient rooftop air conditioner designed for RVs and campervans.
