1. Dometic Penguin II Low Profile Roof Air Conditioner: Top Pick
The Dometic Penguin II is a premium low profile roof AC that delivers strong 13,500 BTU cooling for medium to large vans. In our evaluation of owner feedback and spec sheets, it stands out for its quiet operation and durable construction. The 9.5 inch low profile design fits most van roofs without protruding excessively, and the insulated airbox reduces noise and condensation. Installation is straightforward for those with a standard 14×14 inch roof vent opening.
However, this unit only runs on 120V AC, meaning you need shore power or a generator. It is not suitable for off grid boondocking without a powerful inverter and battery bank. Also, at nearly 75 pounds, it adds significant weight to the roof. Skip this if you primarily camp off grid or have a small van where a portable unit might suffice.
- Ultra low profile design fits vans with limited roof space
- Powerful 13,500 BTU cooling for vans up to 200 sq ft
- Quiet operation with insulated interior airbox
Pros: Excellent build quality and reliability; Easy to install with standard roof vent opening
Cons: Requires shore power or generator; no DC option
2. RecPro RV Air Conditioner Low Profile 13,500 BTU: Best Value
The RecPro RV Air Conditioner offers a compelling balance of price and performance. With 13,500 BTUs and a low profile 10 inch height, it cools vans effectively. Owner feedback highlights the digital thermostat and remote as convenient features. The optional heat pump is a bonus for extending the camping season. Installation is similar to other roof units, making it a popular choice for DIY builders.
On the downside, some owners report that the fan noise is noticeable on high speed, which could be bothersome for light sleepers. The build quality is good but not as robust as the Dometic. Skip this if you prioritize whisper quiet operation or need extreme durability for full time van life.
- Affordable low profile AC with optional heat pump
- Digital thermostat and remote control
- Compatible with standard 14×14 roof opening
Pros: Great value for the cooling capacity; Heat pump provides supplemental heating
Cons: Noisier than premium units on high fan
3. Zero Breeze Mark 2 Portable Air Conditioner: Best Portable
The Zero Breeze Mark 2 is a unique portable AC that runs on 12V DC, making it ideal for off grid van dwellers. In our research, it is praised for its portability and ability to run on solar or a deep cycle battery. The 2,300 BTU cooling is sufficient for a small van or to cool a sleeping area. It includes a battery pack that provides several hours of runtime on a full charge. The unit is lightweight and can be moved easily.
However, the cooling capacity is far lower than roof mount units. It cannot cool an entire large van on a hot day. Also, some owners report that the battery life degrades over time. Skip this if you need to cool a large van or expect high heat conditions. It is best for small vans or spot cooling.
- Battery powered portable AC for off grid use
- Compact and lightweight at 24 lbs
- Dual fan and cool modes with low noise
Pros: No installation required, truly portable; Can run on solar or 12V battery
Cons: Limited cooling capacity for larger vans
4. Dometic RTX 2000 Roof Mount AC: Best 12V Roof Mount
The Dometic RTX 2000 is a dedicated 12V roof mount AC designed for off grid use. It draws power directly from the van’s battery bank without an inverter, which improves efficiency. The 2,000 BTU capacity is modest but adequate for a small van or to maintain a comfortable temperature. Owner feedback highlights the quiet compressor and low profile design that fits under solar panels. Installation requires a 14×14 inch opening and 12V wiring.
However, the cooling capacity is limited compared to 120V units. It may struggle in extreme heat or for larger vans. The price is also higher per BTU. Skip this if you have a large van or need powerful cooling. It is best for small vans with ample battery capacity.
- Runs on 12V DC battery, no inverter needed
- Ultra low profile at 8.7 inches
- Quiet operation with variable speed compressor
Pros: Efficient 12V operation for off grid; Very low profile and lightweight
Cons: Lower cooling capacity than 120V units
5. Houghton 13,500 BTU RV Air Conditioner: Quiet Operation
The Houghton 13,500 BTU AC is designed with sound dampening materials that reduce operational noise. In owner reviews, it is often described as one of the quieter roof mount units. The digital controls and remote add convenience. Cooling performance is on par with other 13,500 BTU units, making it suitable for medium sized vans. Installation is standard, but the weight may require a second person.
However, at 78 pounds, it is heavier than the Dometic Penguin II. Some users also report that the plastic shroud can crack if overtightened. Skip this if weight is a major concern or if you need a unit that can be installed solo.
- Engineered for quiet operation with insulated shroud
- Digital thermostat and remote control
- Fits standard 14×14 roof opening
Pros: Noticeably quieter than many competitors; Good cooling performance for medium vans
Cons: Heavier than similar units at 78 lbs
6. Coleman Mach 15 15,000 BTU Roof AC: High Cooling Capacity
The Coleman Mach 15 delivers the highest BTU output in our roundup at 15,000 BTU. It is ideal for large vans or areas with extreme heat. Owner feedback confirms it cools quickly and maintains temperature well. The metal shroud adds durability. However, the 12.5 inch height is significantly taller than low profile units, which may limit installation on vans with low roof clearance or where solar panels are mounted.
Noise levels are higher, especially on high fan. The unit is also heavier at 85 pounds. Skip this if you have a low roof van or prioritize quiet operation. It is best for those who need maximum cooling and have sufficient roof space.
- Highest cooling capacity in our guide at 15,000 BTU
- Durable metal shroud and construction
- Compatible with standard roof opening
Pros: Excellent for large vans or hot climates; Strong airflow and quick cooling
Cons: Tall profile may not fit low roof vans; Noisier than low profile units
7. Whynter Elite ARC-122DS Portable AC: Dual Hose Portable
The Whynter Elite ARC-122DS is a portable dual hose AC that offers 12,000 BTU cooling. For van use, it can be placed on the floor with the exhaust hoses vented through a window or roof vent. Owner feedback indicates it cools a small to medium van effectively. The dual hose design is more efficient than single hose units. It also functions as a dehumidifier.
However, setup in a van is cumbersome because the exhaust hoses require a secure vent opening. The unit is heavy at 65 pounds and takes up floor space. It also requires 120V AC power, so a generator or shore power is needed. Skip this if you have limited floor space or need a permanent installation.
- Dual hose design for efficient cooling
- Portable with casters and window kit
- Dehumidifier and fan modes
Pros: Good cooling for its size; Dual hose improves efficiency over single hose
Cons: Requires window exhaust setup in van
Frequently Asked Questions
What size air conditioner do I need for my van?
The size depends on your van’s square footage, insulation, and climate. For a small van (up to 60 sq ft), 2,000-5,000 BTU may suffice. For medium vans (60-120 sq ft), 8,000-13,500 BTU is common. Large vans (120+ sq ft) often need 13,500-15,000 BTU. Better insulation reduces the required BTU. We recommend measuring your van’s interior area and consulting the manufacturer’s coverage guidelines.
Can I run a van AC off battery power?
Yes, but only 12V DC units like the Dometic RTX 2000 or portable units like the Zero Breeze Mark 2 are designed for battery power. 120V AC units require an inverter and a large battery bank, which is less efficient. For off grid use, a 12V unit is recommended, but cooling capacity is limited. You will also need sufficient battery capacity (e.g., 200+ Ah) and solar or alternator charging.
How do I install a roof mount AC in my van?
Roof mount ACs require a 14×14 inch roof opening (most vans have a standard vent). You need to cut the hole if not pre existing, reinforce the roof, and seal the unit with a gasket and roof sealant. Electrical wiring for 120V or 12V must be run to the unit. Many owners hire a professional, but DIY kits are available. Always check roof load capacity and clearance for solar panels.
Are portable air conditioners effective for vans?
Portable ACs can be effective for small vans or spot cooling, but they have limitations. They take up floor space, require exhaust venting (often through a window), and are less efficient than roof mounts. Single hose units can create negative pressure, drawing hot air in. Dual hose units are better. For full time van life, a roof mount is usually preferred for permanent cooling.
What is the quietest air conditioner for a van?
Based on owner feedback and spec sheets, the Dometic Penguin II and Houghton 13,500 BTU are among the quietest roof mount units. The Dometic RTX 2000 also operates quietly due to its variable speed compressor. Portable units like the Zero Breeze Mark 2 are quiet on low mode but louder on high. Noise levels vary, so check decibel ratings if quiet operation is critical.
Our Verdict
After researching and comparing specifications, owner feedback, and industry standards, our top pick for most van owners is the Dometic Penguin II Low Profile Roof Air Conditioner for its excellent balance of performance, durability, and quiet operation. For budget conscious buyers, the RecPro RV Air Conditioner offers great value with similar cooling capacity. If you need off grid capability, the Dometic RTX 2000 is a solid 12V option, though with lower BTU.
