Summer is a season that everyone looks forward to, and the prospect of long, warm days makes us all eager to go out and enjoy life.

When the weather outside begins to heat up, though, maintaining a comfortable climate in your vehicle may be difficult.
Although many high-end Class B campers come with Van air conditioning, not everyone can afford it.

Fortunately, there are a plethora of cooling solutions for your vehicle.

We’ve identified the greatest air conditioners for a campervan, ranging from low-tech swamp cooler options to high-end campervan AC systems, all of which should have you feeling fresh as a daisy and ready to confront van life on even the hottest of days!

Getting your campervan’s air conditioner to work (AC vs DC units)

Before we get started, a short note. Many campervan air conditioners on the market, particularly those found in Class B RVs, operate on AC electricity.

Solar panels and battery banks often can’t keep up with the power demands of a campervan air conditioner that works on 120 volts, the same as your home plug. If you want to use your air conditioner for extended periods of time, you’ll need to connect to shore power at a campsite or use a generator.

12-volt air conditioners are much more costly than AC units that run on 120-volts, but they consume far less energy and can be used off-grid with your van’s solar power and battery bank. For the finest campervan air conditioner that operates on 12 volts, you may expect to spend up to four times the price.

In this article, we’ll look at both kinds of air conditioners, as well as one portable air conditioner and a swamp cooler.

BTU Ratings for Campervan Air Conditioners Explained

When shopping for the best air conditioner for a campervan, you’ll note that the BTU value of each unit is clearly stated. What does this signify and why does it matter?

The heat transmission capability of the air conditioner is measured in BTUs, which stands for British Thermal Units.

The amount of heat required to increase the temperature of one pound of water by one degree Fahrenheit is defined as.

In other words, the higher the number, the faster and more effectively the van AC unit can chill the room.

In actuality, the effectiveness of the best air conditioner for a campervan is determined by elements such as the space’s size, insulation, and outside temperature.

A BTU value of 10,000 to 13,000, on the other hand, will keep your vehicle cool even on the hottest of days.

Air Conditioners for Campervans of Various Types

There are a variety of methods to keep your campervan cool, and deciding which sort of van air conditioner would work best for you might be challenging. The following is a rundown of the many sorts of campervan air conditioners.

Air Conditioners for Campervans with Compressors

For a rooftop air conditioner for a van, this is the most preferred choice.

A compressor van air conditioner draws hot air in and cools it using refrigerant. Cool air is pushed back into your home, while heated air is vented to the outside.

The finest air conditioners for a camper van may be ducted or non-ducted, and although they’re the greatest choice for swiftly decreasing the temperature inside, their biggest disadvantage is the amount of electricity they use.

It’s doubtful that your solar and battery system will be adequate to operate this sort of campervan AC unit for an extended period of time unless you intend on utilizing a separate generator or connecting to shore power.

Another factor to consider while shopping for a campervan air conditioner is the unit’s weight.

You’ll need to make sure your van’s roof can support the increased weight and that there’s adequate room for installation.

Campervan Air Conditioners with Evaporative Coolers

These van air conditioners, sometimes known as swamp coolers, chill the air by evaporating water.

Hanging a damp towel in front of a fan is the easiest method to produce this form of cooling, albeit this will create a very humid atmosphere that might lead to mold and mildew.

Many van residents utilize the wonderfully cool rooftop evaporative coolers that are available.

However, there are certain drawbacks to this sort of campervan air conditioner.

An evaporative cooler works best in low-humidity situations, which is excellent if you’re just going to use it in the desert, but not so great if you’re heading to Florida!

An evaporative cooler also requires a lot of water to operate, which might be a significant disadvantage.

Portable Air Conditioners for Campervans

If you want something for occasional usage that can be stowed when not in use, this sort of machine might be the perfect air conditioner for a campervan.

Household models are bigger and have plenty of cooling capacity for use as a campervan AC unit, but they must be vented outdoors, which will need some ingenuity with your vehicle.

Smaller portable air conditioners are a great choice, particularly for confined spaces.

Although you won’t be able to chill down your whole living area with a portable air conditioner, they are simpler to vent, more inexpensive, and frequently operate on battery power.

Window Air Conditioner for Campervans

Window air conditioners aren’t meant to be portable, but due to their superior cooling capacity, they remain a favorite choice among van dwellers.

Although a window unit is large and cumbersome, it may be the finest air conditioner for a campervan, particularly if the arrangement of your van is designed to accommodate it.

When the Temperatures Start to Rise, here’s How to Keep your Campervan Cool

There are a number of things you can do to make your camper van more comfortable, whether or not you’re utilizing the finest air conditioner for a camper van.

Some of them may seem apparent, while others may look redundant, but when the heat is on, even little adjustments may make a big impact!

Window Treatments/Curtains

Aside from providing privacy, employing reflective window coverings and curtains in your vehicle may significantly reduce the temperature inside, often by as much as 10 or 20 degrees.

Windows with Vents

If you’re outfitting a van, you should absolutely consider venting the windows. There are a variety of choices available, including sliding windows and crank-open windows.

A mesh screen will keep out unpleasant creepy-crawlies while still allowing for critical ventilation, particularly if a vent fan is installed.

Portable fans/roof fans

A fan will not be able to cool the inside of your vehicle on a hot day, but it will bring the temperature down to equal the outside temperature.

The Maxxair and Fan-Tastic are the two most popular roof fans for van living, and either one will provide much-needed air circulation. A modest, USB-powered fan may also make a big impact and is an inexpensive, space-saving method to circulate air within your truck.


Insulating your camper van is critical not just for keeping the heat in during the winter, but also for maintaining a pleasant climate during the summer, particularly if you use a van air conditioner.

Shade While it may seem obvious, parking your van in the shade may make a significant impact on even the warmest of days.

Parking in the shadow will protect your vehicle from the sun’s rays and limit the temperature from rising too high.

Take a Trip to a Cooler Location

Remember that you have the option to leave! If you’re feeling hot, there’s usually someplace nearby that will be cooler.

Driving to the seaside is frequently the best option, since evening temperatures are normally considerably more comfortable at higher altitudes.

The Best Air Conditioners For A Campervan Conclusion

When it comes to heat tolerance, everyone is different, and although some people like the sensation of a hot day, others may go for the air conditioner.

A campervan air conditioner is essential if you’re traveling with dogs or children, particularly during the summer months.

Taking the edge off the heat, whether with a powerful rooftop air conditioner or a tiny, portable one, can make life in your van much more comfortable.
