RV social media pages are on fire with complaints from RVers who can’t keep their cool this summer. Their A/C units are blasting warm air, or just aren’t cool enough. Some may need to adjust their expectations, while others may actually need a new air conditioner. What’s the best RV air conditioner? There’s a lot of wiggle-room for a claim here, but one tech-oriented magazine has some suggestions.
Popular Mechanics says it knows the best RV air conditioners
Popular Mechanics’ guide to the best RV air conditioners in 2025 focuses on helping RVers find a unit that fits their specific rig size, cooling needs, and budget. The editors consulted with RV dealers and an RV rental professional to identify standout models, factoring in performance, durability, ease of installation, and real-world feedback.
Whether you’re a full-timer in a Class A motorhome or an occasional camper in a smaller trailer, the guide offers practical recommendations to keep your RV cool and comfortable.
Top of the list
At the top of the list is the Dometic Brisk II, a 15,000 BTU unit known for its reliable cooling and rugged build. It’s praised for broad compatibility with a wide range of RVs and works with both ducted and non-ducted air distribution systems. This makes it a flexible choice for RV owners unsure about what their setup can handle. The Brisk II also earns points for easy installation and durability, even after extended use on the road.
We looked around and found the 15,000 BTU units for as low as $1400. If your rig is smaller, a 13,500 BTU unit can be had for as little as $908.
Shopping on a budget?
For travelers seeking value without sacrificing performance, the ASA Electronics Advent Air ACM135 is recommended as the best budget option. This model produces 13,500 BTUs of cooling and is built to fit standard 14-inch roof openings, simplifying installation. It’s ideal for smaller RVs, moderate climates, or weekend travelers who don’t need high-end features but still want dependable cooling during warmer months.
We found one of these for just a bit over $600.
Quieter than most RV air conditioners
The Furrion Chill HE, rated at 15,500 BTUs, stands out as a heavy-duty performer. It’s built for larger RVs or for those who frequently camp in hot weather. Popular Mechanics notes that the Chill HE is quieter than many rivals and designed with modern features, including advanced control options. Its high output and quiet operation make it a strong candidate for full-time RVers or families who need reliable cooling throughout the day and night.
We found the Furrion 15,500 BTU units just under $1,000.
Popular Mechanics offers help on choosing right options
The article also offers guidance on how to choose between ducted and non-ducted systems. Ducted air conditioners push cooled air through a system of vents throughout the RV, offering even distribution. Non-ducted models push air directly into the space below the unit, making them more common in smaller rigs. Knowing which setup your RV has is essential before selecting a unit.
Another important factor is the physical size and fit of the air conditioner. Most RV A/C units are designed to mount into a 14-inch-square roof opening, which is a common standard. That said, some models are taller or heavier than others, which could be an issue for RVs with tight roof clearances or weight restrictions. The guide advises buyers to double-check their RV’s specs before ordering.
Throughout the article, Popular Mechanics emphasizes ease of installation and maintenance. Many of the recommended models are designed to be user-installable for those comfortable with basic RV repairs. Still, some units may require professional help, particularly when upgrading from older models or switching from non-ducted to ducted systems.
Noise level is another consideration. Some RVers prioritize a quiet cabin, especially at night. Models like the Furrion Chill HE and Dometic Brisk II earn high marks for relatively quiet operation, especially compared to older or cheaper models that can be loud and disruptive.
Summing it up
In summary, the guide helps RVers match their cooling needs with the right air conditioner. The Dometic Brisk II offers broad compatibility and strong cooling, the Advent Air ACM135 provides solid value, and the Furrion Chill HE delivers power and quiet performance for more demanding use. No matter what you drive or how often you camp, choosing the right RV air conditioner can significantly improve your travel experience.

We have hard wired Soft Starts in our current Coleman 15k heat pump units. we can run both on 2 Honda 2000’s when yoked together. Do the new units allow this?
Yes. Inverter compressor A/C units are more efficient, use less power, create less noise, require no soft-starts and are superior at maintaining desired temperatures. The compressor is variable speed so no huge spike to get it going. Most have a fan for the condenser and one for the evaporator instead of a single fan for both so that cooling efficiency isn’t compromised by fan speed.
The biggest current drawback is their upfront cost isn’t the cheapest and the long term durability is unknown since 20 years of actual experience takes about 20 years.
We’re considering installing a mini-split. The noisy part (condenser) is outside, runs at a lower wattage, includes a heat pump, and costs less than a new roof unit. We’ll see.
I have seen these mounted on the rear of some trailers and often wondered about that same scenario you mention.
What about the Coleman Mach air conditioners?? Mine is 8 years old and still works great. When did Popular Mechanics become an authority on RV systems? Plus, I’ve never even heard about the Advent Air ACM135…
My 4-yo Coleman-Mach heat pump had a meltdown that would have required a new, $220 control box + labor. And I wouldn’t have repaired it without installing a $280 Soft-Start too. I probably could have installed one of those Advent ACMs for the total repair cost.
But, since we live in Colorado and camp primarily in the dry SW, I replaced it with a $650 TurboKool evaporative cooler. This 12v system works exactly like the “swamp cooler” I have had on my house for nearly 50 years. And the TurboKool works off-grid from battery power and solar panels even on the hottest summer days. However, evaporative coolers really work well only between the 100th Meridian and the Sierra/Cascade mountains.
In the truck camper, I changed my Dometic to a Houghton. The AC dumps directly into the RV, so no duct work to decrease the noise. The Houghton is super quiet and includes a heat pump. Very happy with the Houghton.
Thank you for sharing the recommendations of Popular Mechanics, Russ and Tina! This made me check our build sheet. We have two Dometic 15M Penguin air conditioner/heat pump units. Have a great week and safe travels!
In new RV, the Dometic is installed. not quiet by any measurement.
