1. RecPro RV Air Conditioner 13,500 BTU Low Profile: Best Overall
In our evaluation, the RecPro 13,500 BTU unit stands out for its balance of cooling power and low-profile design. Based on the spec sheet and owner feedback, it delivers consistent cooling in vans up to 200 square feet. The unit supports both ducted and non-ducted configurations, making it versatile for different van layouts. Owners report that installation is straightforward with the provided gasket and mounting hardware.
However, the weight of 75 lbs may require a reinforced roof or two-person installation. Some users noted that the thermostat can be slightly inaccurate. If you have a smaller van or need a lighter unit, consider a 9,000 BTU model. But for most full-size van conversions, this is a top performer.
- Low profile design fits under standard van roof racks.
- Ducted and non-ducted operation for flexible airflow.
- Quiet operation with owner feedback averaging 55 dB.
Pros: Excellent cooling for medium vans.; Easy to install with included gasket and hardware.
Cons: Heavier than some competitors at 75 lbs.
2. Dometic RTX 2000 Roof Top Air Conditioner: Premium Pick
The Dometic RTX 2000 is a premium roof air conditioner designed for van life and off-grid use. Based on manufacturer specs and owner reviews, its DC compressor runs efficiently on battery power, and the soft start reduces generator strain. The ultra-low profile fits under most roof racks, and the unit is known for its quiet operation.
However, the cooling capacity is modest at 2000 BTU, making it suitable for small to medium vans only. The price is significantly higher than traditional RV AC units. If you need to cool a large van or are on a strict budget, this may not be the best fit. But for energy-conscious van dwellers, it is a top-tier choice.
- High efficiency DC compressor for off-grid use.
- Ultra low profile at only 6.5 inches tall.
- Built-in soft start for minimal generator load.
Pros: Excellent build quality and durability.; Very quiet operation at 38 dB.
Cons: Higher purchase price compared to AC units.; Limited cooling capacity for large vans.
3. Coleman Mach 15 15,000 BTU Roof Top Air Conditioner: Powerful Cooling
The Coleman Mach 15 is a workhorse for large van conversions that need maximum cooling. In our research, owner feedback consistently praises its ability to cool quickly, even in 100+ degree weather. The unit is a standard in the RV industry, so parts and service are widely available. Installation is straightforward for those with some mechanical skill.
However, the unit is louder than many competitors, with some owners reporting 60-65 dB. The height (around 12 inches) may be too tall for vans with low roof clearance. If noise or roof height is a concern, you might prefer a low-profile model. But for raw cooling power, the Coleman Mach 15 is hard to beat.
- High cooling capacity for large vans and hot climates.
- Reliable compressor with over 50 years of OEM use.
- Simple controls and easy maintenance.
Pros: Powerful cooling even in extreme heat.; Proven durability from a trusted brand.
Cons: Noisy operation compared to low-profile units.; Bulkier design may not fit low roof vans.
4. Furrion Chill 13,500 BTU RV Air Conditioner: Sleek Design
The Furrion Chill offers a sleek, modern look that many van converters appreciate. Based on owner feedback, it provides adequate cooling for vans up to 200 square feet, and the low profile fits under many roof racks. The unit includes a multi-speed fan and adjustable thermostat for basic control.
However, we found mixed reviews on cooling consistency, with some owners noting hot spots in the van. The customer service experience has been criticized in online forums. If you prioritize aesthetics and are willing to risk some variability, this is a viable option. For more reliable performance, consider the RecPro or Dometic.
- Modern aesthetic with a low 9.5 inch profile.
- Multi-speed fan and adjustable thermostat.
- Compatible with most standard RV roof openings.
Pros: Attractive design that blends with van roofline.; Decent cooling performance for medium vans.
Cons: Some owners report inconsistent cooling.; Customer service can be slow to respond.
5. Airxcel 47000 13,500 BTU Roof Top Air Conditioner: Budget Friendly
The Airxcel 47000 is a budget-friendly option that still delivers 13,500 BTU of cooling. Based on owner feedback, it works well for those on a tight budget who need basic cooling. The unit fits standard roof openings and installation is straightforward. It provides sufficient cooling for medium-sized vans in moderate climates.
However, owners report that it is louder than higher-end models, and the plastic exterior may show wear over time. Some users experienced vibration issues. If you are building a van on a budget and can tolerate some noise, this is a solid choice. For a quieter, more durable unit, consider spending a bit more.
- Affordable price point for budget builds.
- Standard 14×14 inch roof opening compatibility.
- Simple mechanical controls.
Pros: Good value for the cooling capacity.; Easy to install with common tools.
Cons: Noisier than premium units.; Plastic housing may not be as durable.
6. Atwood Air Command 13,500 BTU Low Profile: Quiet Operator
The Atwood Air Command is designed for those who value quiet operation. In owner forums, many note that it runs quieter than the Coleman Mach series. The low profile helps with aerodynamics and clearance. It is ducted, which can provide more even cooling throughout the van if you install the optional ducting kit.
However, we found that its cooling capacity is merely average, and some owners in hot climates reported it struggled to maintain comfortable temperatures. The ducting kit is an extra cost. If quiet operation is your top priority and you live in a mild climate, this could work. For hotter regions, look for higher BTU or better-rated units.
- Low profile at 9 inches for better aerodynamics.
- Ducted system for even airflow distribution.
- Quieter operation than many competitors.
Pros: Relatively quiet for a roof AC.; Low profile design fits under racks.
Cons: Cooling performance is average at best.; Ducting kit sold separately.
7. Houghton 9,000 BTU Low Profile Roof Air Conditioner: Compact Fit
The Houghton 9,000 BTU unit is a compact option for small van conversions or as a supplementary cooler. Based on our research, it is lightweight and easy to install, making it a good choice for DIY builders. The low profile allows it to fit under most roof racks. It provides adequate cooling for very small spaces like a minivan or small camper.
However, the 9,000 BTU capacity is insufficient for full-size vans in hot weather. Owner feedback mentions occasional reliability problems, such as compressor failures. If you have a small van or need a secondary unit, this might work. For primary cooling in a standard van, we recommend a higher BTU model.
- Compact and lightweight at 55 lbs.
- Low profile design only 8 inches tall.
- Suitable for small vans or trailers.
Pros: Easy to install due to lighter weight.; Fits small vans with limited roof space.
Cons: Limited cooling capacity for larger vans.; Some owners report reliability issues.
Frequently Asked Questions
Can I install a roof AC on any van?
Most roof AC units require a 14×14 inch roof opening and a flat roof area. Check your van’s roof structure for reinforcement. Many vans come prepped from the factory, but older models may need additional bracing. Always verify the unit’s weight and your roof load capacity.
How much power does a roof AC consume?
Roof AC units typically draw 12-16 amps at 115V AC for 13,500 BTU models. DC units like the Dometic RTX draw less but still require significant battery capacity. For off-grid use, you will need a robust battery bank and solar or generator.
Do I need a ducted or non-ducted roof AC?
Ducted units distribute air through ceiling vents for even cooling, ideal for larger vans. Non-ducted units blow air directly from the unit, simpler and cheaper. Choose based on your van layout and cooling needs.
How noisy are roof AC units?
Noise levels vary. Low-profile DC units like the Dometic RTX are quietest at around 38 dB. Traditional units like the Coleman Mach can be louder, around 60 dB. Check decibel ratings and owner reviews for real-world noise.
Can I run a roof AC on battery power?
Yes, but only DC-powered units like the Dometic RTX are designed for battery use. Standard AC units require a generator or shore power. DC units are more efficient but have lower cooling capacity.
