Campervan Air Conditioner BTU Ratings Explained
When you’re looking for the best air conditioner for a campervan, you’ll quickly notice that each unit’s BTU rating is prominently displayed. Why does this matter, and what does it mean?
BTU stands for British Thermal Units, and measures the heat transfer capacity of the AC.
This is defined as the amount of heat needed to raise the temperature of one pound of water by one degree, Fahrenheit.
Essentially, the higher the number, the quicker and more efficiently the van AC unit can cool down the space.
In practice, the efficiency of the best air conditioner for a campervan depends on factors like the size of the space, how well-insulated it is, and the outside temperature.
Generally speaking, though, a BTU rating of 10,000 to 13,000 will keep your van nice and cool on the spiciest of days.
Different Types Of Campervan Air Conditioners
There are many different ways to keep your campervan cool, and it can be difficult to choose which type of van air conditioner will work best for you. Here’s the lowdown on the different types of campervan air conditioners.
Compressor Campervan Air Conditioners
This is the most popular option for a rooftop air conditioner for a van.
A compressor van AC unit sucks in hot air and cools it by using refrigerant. The cool air is blown back into your living space, and hot air is expelled outside.
These best air conditioners for a camper van can be ducted or non-ducted, and although they’re the best option for quickly lowering the temperature inside, the main drawback is the amount of power they’ll draw.
Unless you plan on using a separate generator or hooking up to shore power, it’ll be unlikely that you’re solar and battery setup will be enough to run this type of campervan AC unit for long.
Another thing to consider when looking at this type of campervan air conditioner is the weight of the unit.
You’ll need to be sure the roof of your van can handle extra weight, and whether or not there’s enough space for installation.
Evaporative Cooler Campervan Air Conditioners
Also known as swamp coolers, these van AC units work by cooling the air through the evaporation of water.
The simplest way to achieve this type of cooling is to hang a wet towel in front of a fan, although this will create a really humid environment that could lead to mold and mildew.
There are some really cool rooftop evaporative coolers out there, and many van dwellers use them.
However, this type of campervan air conditioner has its limitations.
An evaporative cooler only really works well in very low-humidity environments, which is great if you’ll only be using it in the desert, but not so great if you’re on your way to Florida!
You’ll also need a lot of water to run an evaporative cooler, which can be a serious downside.
Portable Campervan Air Conditioners
This type of unit could definitely be the best air conditioner for a campervan if you want something for occasional use that can be stored when not in use.
Household versions are larger and definitely have enough cooling capacity for use as a campervan AC unit, but they need to be vented outside and you’ll need to get creative to achieve this in your van.
Smaller portable air conditioners are an excellent option, especially for use in specific areas.
These van AC units are easier to vent, more affordable, and often run on battery power, although you’ll struggle to cool down your entire living space with a portable air conditioner.
Window Campervan Air Conditioner
Window air conditioners aren’t designed to be portable, but they continue to be a popular option among van dwellers, thanks to their supreme cooling power.
A window unit is big and bulky, but it could be the best air conditioner for a campervan; especially if you design the layout of your van to accommodate it.

How to Keep Your Campervan Cool When Temperatures Begin To Rise
Whether or not you’re using the best air conditioner for a camper van there are quite a few things you can do to make things more comfortable in your van.
Some of these may appear obvious, and some might seem superfluous, but when the heat is on, small changes can make all the difference!
Apart from giving you privacy, using reflective window coverings and curtains in your van can make a huge difference, sometimes even lowering the temperature inside by 10 or 20 degrees.
Using a mesh screen will keep out unwanted creepy-crawlies, and you’ll be able to create valuable airflow, especially if you also install a vent fan.
Roof Fans/Portable Fans
Although a fan won’t be able to cool the interior of your van on a hot day, it can bring the temperature down to match the temperature outside.
The two most popular roof fans for van life are the Maxxair and Fan-Tastic, and either one will give you much-needed air circulation. A small, USB-powered fan can also make a lot of difference and is a cheap, space-saving way to get the air moving inside your van.
Insulating your camper van is super-important, not just to help keep the heat inside during the winter, but also to maintain a comfortable environment during the summer, especially if you’re using a van AC unit.
This might seem like a no-brainer, but parking your van in the shade can make a big difference on the hottest of days.
Parking in the shade will keep the sun’s rays at bay and prevent the temperature inside your van from becoming unbearable.
Drive Somewhere Cooler
Don’t forget that you’re free to leave! If you’re suffering in the heat, there will often be somewhere not too far away that is going to be cooler.
