THE BEST AIR CONDITIONERS FOR MOTORHOMES,
CARAVANS & VANS

Why a good air conditioner is essential for summer vacations on the road

Summer, sun – and stuffy air in your camper? Not on our watch. A reliable air conditioner ensures comfortable
temperatures, better sleep, and a clear head while you travel. Whether you‘re living full-time in your van or exploring on
weekends – nothing beats cool air in the cabin. Plan to travel to warmer regions? A high-performance, low-consumption
cooling system is essential. Compressor air conditioners are the most efficient ones.

WHAT A COMPRESSOR AIR CONDITIONER DOES FOR YOU

Feel well, sleep well – with just the right temperature and humidity

We all want to enjoy a pleasant temperatures in our camper, and humidity plays a decisive role too. Most of us feel more comfortable when the room temperature is around 22 °C and the humidity between 40 and 70 %. To create these conditions in a motorhome, caravan or campervan, the air must be cooled down and dehumidified at the same time. This calls for a compressor-powered AC system.

Compressor air conditioner versus evaporation systems

Compressor air conditioners are the most effective ones. Unlike A/C systems based on evaporation cooling, they also reduce the air humidity in your vehicle – ideal conditions for a pleasant stay and a restful sleep. 

 

5 KEY THINGS TO CONSIDER WHEN CHOOSING AN AIR CONDITIONER

#1 Vehicle size, insulation, window areas

The vehicle length is a useful guide when selecting an air conditioner. Also consider the interior of your motorhome or caravan. Do you want to air condition the whole vehicle or part of it? How large is the room to be cooled? Vehicles can have entirely different thermal properties. A well insulated caravan with small windows will require less cooling performance than a vintage camper with poor insulation or a full-size RV with panorama windows.

#2 Installation – on the roof or in a storage compartment?

Recreational vehicles offer only two places where the installation of an air conditioner makes sense: on the roof or in a storage compartment (under-bench air conditioners). Either version has its own benefits.

 

Benefits of a roof air conditioner

• Fast installation – air conditioner replaces the roof window, no ducting required
• Superior efficiency – system uses the physical principle that cold air sinks
• Storage compartment is kept free – especially beneficial in smaller campers with limited storage space
• Do you want both – a roof air conditioner and natural light from a roof window? Opt for Dometic FreshLight 2200.

Benefits of an under-bench air conditioner

• No extra height added to your vehicle – no problems with height restrictions
• You can keep the roof window and enjoy natural light from above
• Flexible air distribution via the ducting system – concentrated or in several rooms

 

#3 TRAVEL DESTINATION – NORTH SCANDINAVIA OR
SUMMER HEAT OF SICILY?

The Scandinavian climate will not challenge your air conditioner to the extremes. A unit with a smaller capacity rating will do. If you regularly travel to southern destinations, choose a powerful air conditioner (2600 W or more). Especially so, if you have children or pets on board. Hot summer days or tropical nights – a powerful enough air conditioner can be a real blessing.

Our tip: Don’t skimp on power!

Make sure the power rating of the air conditioner you pick is a bit higher than necessary for your vehicle size. You can always turn the A/C down to consume less energy.

 

#4 SMOOTH OPERATION AT THE CAMPSITE – WITH HASSLE-FREE START-UP

Will your Dometic air conditioner reliably start up even on campsites with unstable power supplies? The answer is yes. Our FreshJet FJX4 2200, FreshLight 2200 and FreshWell FWX4 models feature a soft-start function, which supports the engine during the critical start-up phase. As a result, the start-up phase is much shorter – it’s over before the fuse can blow.

Our tip: With the new generation FreshJet FJX7 roof air conditioners, there are no start-up problems at all. These premium models come with an electronic inverter compressor – no current peaks in the start-up phase.

 

#5 NOISE LEVEL – IMPORTANT FOR A GOOD NIGHT‘S SLEEP

Do you want to sleep better in your camper next summer? Opt for an A/C system with a low noise level. Dometic air conditioners are among the quietest around. Our FreshJet FJX7 models are even quieter. Thanks to the electronic inverter compressor, there’s scarcely any vibration. The compressor speed automatically adapts to the cooling requirements, without the typical ON/OFF cycles known from conventional compressor systems.

 

 

ALL-IN-ONE AIR CONDITIONERS

Cool, heat and purify the air in the cabin

A select few air conditioners can do it all: cool, heat and purify. If you are likely to travel long distances in your RV and experience a range of climate conditions, an all-in-one air conditioner ensures you will always be comfortable.

Clean air – as standard or for retrofitting

Air purification is a standard feature on all new generation Dometic air conditioners with electronic controls (FJX7 and FJX4 series). If you have an older-make, or a FreshJet FJX4 1500M with manual controls, you can retrofit the Dometic BREATHE 2500 add-on kit to enjoy clean and healthy air in your camper.
