Campervan Air Conditioners: Staying Cool for Vanlife

Van life air conditioning: The challenge of cooling your van

It can be a struggle to find the best campervan air conditioner for your van build.

Especially considering that there’s no way to seriously lower high temps without burning a lot of watts.

To clarify that last statement, I’m talking about dropping from 90 ℉+ (32 ℃) to a comfort zone around 75 ℉ (24 ℃).

Yes, you can move air with fans and create a more comfortable feeling space, but actually dropping the temperature of the interior of your van burns serious wattage.

Vanlife air conditioning can be complex and confusing

Installations can require duct work with holes cut in the exterior, control panel installation, wiring and other technical work.

Our goal with this resource guide is to educate you so you can choose the best 110 or 12 volt air conditioner van life.

This article will help you decide which system is right for your van, according to your travel area, style and campervan build.

And of course I’ll be recommending the most trusted, cost effective and durable products.

This article will not make you an expert on the vast science of heating and cooling. For that, I’ve researched and included some great links from experts in the field. Read on for that…

How do I keep my campervan cool in the summer?

Before going all in on an a van air conditioner, you should start with the basics.

Here are our tips to keep your camper van cool in the summer.

  • Curtains for campervan temperature control: Reflective window coverings and window tint can drop the internal temperature of your van by up to twenty degrees!
  • Fans and roof vents for camper van cooling and air quality are perhaps the most effective non-AC approach to keeping your campervan cool in the summer.
  • Insulating a campervan to keep the heat out and the cool in is a must. It might be time to revisit the insulation materials and design in your van.
  • Shade is under rated. Park in the shade to avoid direct sunlight on your van. You can also create your own with the right awning for campervan shade.
  • Spend as little time in the van during the day as you possibly can.
  • You can lower your body temperature by staying hydrated and drinking cold water. It’s nice to have a good 12 volt fridge freezer stocked with ice and cold beverages.

These basic steps will give you a foundation for a cool van in the summer and will help your van AC run more efficiently.

 

The Struggle is Real

window shaker Vansage.com campervan air conditioner

I have to chuckle when I see an air conditioning unit made for residential interiors (aka “window shaker”) hanging off the side or back of a van.

The thought process goes something like this; “I’m sick of roasting and I’m not spending a fortune on a portable RV or Van specific system!”

And more power (quite literally) to those road warriors.

I don’t mean to make light of the necessity and even urgency involved in having a good campervan air conditioner.

Extreme heat and financial realities can make solutions like this seem like the only option.

But issues like long term costs, efficiency, space savings, weight, durability and noise are also very real, and I believe that through education and planning, cooler heads can prevail.

Campervan Air Conditioners: Beyond comfort

Have you ever spent a night, a weekend or longer in a climate that’s so extremely cold or hot that it’s all you remember about the trip? I certainly have.

Campervan travel can be full of challenges, and it’s important to have some control over our environment for sleep and driving comfort.

Some people adjust easily to higher temps, so a cool sleeping space might not be a big deal. But most of us don’t get much rest when it’s too hot at bed time.

Personally, I also want to be able to escape the heat during the day when it’s very hot.

If you’re traveling with pets, a cool van can be an absolute necessity when you have to leave them alone for any length of time.

So while the initial cost of a quality campervan air conditioning system might seem high on paper, the value of a comfortable living space can mean the difference between fun, memorable travel, and miserable, sweaty, even dangerous misadventures.

Quality & design of campervan air conditioners

There are many issues to consider when choosing an AC system for your van. Three of the major considerations are power usage, durability and noise.

RV AC unit efficiency

If you’re only using shore power and have no plans to camp off grid, you won’t need to worry as much about power usage for your AC unit.

For those who will be more self sufficient, power efficiency is a major priority. A full compressor or heat pump unit will burn lots of power, so you’ll want to maximize your on board power, while minimizing AC and Heat use, when possible.

Durability of your campervan air conditioner

It’s important to take durability seriously, as campervan air conditioners experience vibration and jostling that home units don’t. This is why I don’t recommend a “window shaker” or other residential type unit for your van.

Fortunately there are several brands and models that have been on the market for a while, so durability tends to be part of product ratings by consumers.

Keep in mind that most air conditioning units cost enough that you’ll want replacement and repair parts to be available. We’ve done our best to locate those units for our reviews, below.

How quiet are campervan air conditioners?

Noise can be a serious concern. After a long day of driving, the last thing you want is a noisy machine kicking on, humming, buzzing… You want a nice quiet space to rest, enjoy a meal, sleep…

Scanning the reviews of most campervan related machinery, you’ll find noise related comments.

If you sleep like a log, quiet will be of less concern, but even the heavy sleepers can be annoyed by persistent machine noise during the day.

Noise as it relates to AC unit quality

A noisy air conditioner can be a sign of poor quality. In HVAC equipment, quiet is achieved by fan blade balancing, insulation, proper fit of mounting and other hardware, as well as build quality of motors and compressors.

So when looking for air conditioning products to recommend to our readers, quiet is a major factor.

Types of Campervan Air Conditioners technology

In recent years virtually every available A/C technology has been adopted specifically for RV and Campervan space and voltage needs.

Below I’ve outlined the three major types of air conditioning.

Compressor Type Air Conditioning

Compressor air conditioning systems are the most effective way to lower air temperature. They also use the most energy. Fortunately, there are many options for compressor A/C units, in multiple sizes and price ranges, for campervans.

From Wikipedia:

“In the refrigeration cycle, heat is transported from a colder location to a hotter area. As heat would naturally flow in the opposite direction, work is required to achieve this. A refrigerator is an example of such a system, as it transports the heat out of the interior and into its environment. The refrigerant is used as the medium which absorbs and removes heat from the space to be cooled and subsequently ejects that heat elsewhere.”

Alternating between cooling with a compressor unit and circulating air with a roof vent fan is a highly effective way to reduce internal van heat in any climate.

But to go this route for cooling, you’ll need to plan for high energy use. This may include installing a generator, comparatively massive battery banks, or driving a few extra miles for a shore power hook up if the heat is really bad.

Swamp or Evaporative type Cooler

Again, I’ll rely on Wikipedia to get us started on evaporative cooling details.

“An evaporative cooler (also swamp cooler, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from typical air conditioning systems, which use vapor-compression or absorption refrigeration cycles.”

A while back I was considering a swamp cooler and the MightyKool 12-volt model K2 was clearly a great option.

I checked out the FAQ section on the MightyKool site and found this at the top of the page:

Question: Will the Model K2 cool an entire Camper, Sleeper, Boat, Vehicle, Tent, etc.?

Answer from MightyKool: No, as that would take an Air Conditioner and there is no such thing in the World as a self-contained 12-volt A/C. The 12-volt model K2 Evaporative Cooler will however cool People or Pets IN a Camper, Sleeper, Vehicle, Boat, tent etc. with Proper Ventilation.

There’s a lot to unpack in this short bit of Q & A.

By “self contained 12-volt A/C”, he means an A/C unit with it’s own power source that does not require outside ventilation or drainage.

Some might debate this statement, but I tend to agree with it, as all these things are required for a compressor/evaporation A/C unit to function and they can be considered external to the unit.

Nonetheless, many van dwellers use and even prefer swamp coolers over other types.

As swamp coolers don’t cool interiors, but only cool the person or animal they’re directed at, they might leave you wanting more if you’re traveling in very hot climates.

But, again, lots of van and RV dwellers are okay with that and prefer the simplicity and relatively low power use of an evaporative cooler.

Mini-Split Heat Pump Air Conditioning technology

Heat pumps work similarly to compressor type AC, but they can heat as well as cool the air. It’s complicated, so here’s a Youtube video that does a great job of simplifying how heat pumps work and why they’re so efficient.

Because I travel through a variety of climates, the mini-split is my favorite source of both A/C and heat in non-diesel vans (In a diesel powered van, I prefer diesel heating systems).

For example, in mid March of 2018, I was parked on BLM land in Joshua Tree, California. The daytime temps were in the upper eighties.

That’s fine if you’re out and about, but might result in some roasting inside the van during the day.

At night, however, with a steady desert wind blowing, we experienced lows in the mid 40’s.

So, on this trip I ran the Mini Split for about 30 minutes during a daytime nap and then again for part of the night to get the temp above 60 as we hadn’t packed much for blankets or lower temp sleeping bags.

The built in thermostat on the unit kept the van between 75 and 80 degrees under any conditions and only kicked on a few times, so power use was minimal.

Of course in hotter/colder situations, power use will be higher.

Heat pump technology has come a long way in the last decade, making smaller RV and Campervan “mini split” units durable, efficient and more affordable.

Product Recommendations for Campervan Air Conditioners

I wish there were a half dozen of each type of Air Conditioner for Campervans to recommend, but the field is pretty narrow for each type of AC.

The good news is that the products that are available are great.

If you’re not committed to diesel or propane gas, or other electrical heating for your Campervan, these mini split units are a great solution to all your heating and cooling needs.

Assuming you’ve got the solar, battery, a quiet generator and shore power gear to support the power use, a mini split makes heating and cooling so simple, you rarely have to think about it.

Swamp or Evaporative 12 volt campervan air conditioners

Unfortunately, there are not a lot of swamp coolers available on the market. This is due to the limited ability of these units to cool living space.

In order to get the most out of an evaporative cooler, the unit needs to directed at the person (or pet) they’re intended to cool.

This notice from the manufacturer of our top pick for evaporative coolers, the MightyKool K2, warns against the limited cooling capacity of their product:

“If your area is humid, email us before ordering the Model K2 to make certain it will work for you, as it uses water to produce cool air.”

    It is interesting that mini-split heat pumps work similarly to compressor ACs. My wife and I just bought our first van and we are stripping everything out before installing ac units and heat pumps. We may consider a mini-split heat pump air conditioning so that we can get heat and cold air control in our van.

      Hey Brian
      The marine industry has a wide variety of low btu AC units, but they tend to not be rooftop and very expensive.

      We’ll be writing about such options in the near future. Please check back.

    Adding reflectix insulation to all my windows helped to keep my van 10-20 degrees cooler. But, that also means you need ventilation and air flow or to run the aC. Keeping the heat out can sometimes make it hot inside. so Fans and an inverter helped a lot. I ran the AC on my generator in the van and OMG I cried not realizing it used all my fuel over night. I had some but not much left. Never do that again lol

      Hey There Bloggin Brandi
      Cool channel and thanks for the comment.

      Yes, a generator needs it’s own fuel supply on board, I think. But it’s a great solution for those very cold or very hot nights because sleep is important.

      And yes, ventilation is a biggie and is so specific to type of van/rv.

      Good luck on your travels.

    This is all excellent info. I have a Transit Connect, so a mini camper van. Would these units overpower and which would you personally recommend? Thank you.

      Hey Nancy. If your van is well insulated, you can get away with a lower btu output and that will also save on battery use.
      Of course there are other considerations such as ambient (outside) temperature, ventilation…
      Please report back with your experiences with the unit you decide on.
