The Complete Buyer’s Guide to Caravan Air Conditioners for Australian Travelers
Travelling around Australia in a caravan is an unforgettable experience. But the heat can be intense, and the nights can sometimes feel chilly. A reliable air conditioner makes all the difference, keeping inside the caravan cool during scorching days.
This guide is here to help you choose the right air conditioner for your caravan. With so many options available, it can be hard to know where to start. We'll walk you through everything you need to know, so you can find the perfect unit to suit your van and your travels.
Why Choose a Caravan or RV-Specific Air Conditioner?
Caravan air conditioners are made for life on the road. Rooftop units are weatherproof, keeping water out even during heavy rain. They are built to handle constant vibrations and uneven roads, which household air conditioners can't manage.
These units are compact and efficient, fitting perfectly in caravans. They are tailored for mobile use, ensuring your van stays cool or warm in any condition. With a rooftop unit, you get reliable performance and protection from the elements.
Types of Air Conditioners for Caravan and RVs
Rooftop Air Conditioners
Rooftop air conditioners are mounted on the roof of your caravan. They save space inside and provide efficient cooling as cold air sinks. These units are great for larger caravans and motorhomes.
However, they add height to your caravan, which can be an issue in parking garages, underpasses, or other spaces with low clearance. Pop-top caravans may need roof modifications to support their weight. Make sure your roof is strong enough before choosing this option.
Under-Bunk Air Conditioners
Under-bunk air conditioners are installed under beds or inside cabinets. They are a good choice if you want to keep your roof space-free for other accessories. These units are quieter and have a low-profile design, making them ideal for smaller caravans or pop-tops.
The main drawback is they take up storage space inside your van. You'll also need ducting to distribute the air throughout your caravan. This option works best if you prioritise saving roof space.
Cooling and Heating Systems
Reverse Cycle Systems
Reverse cycle systems are the most common type of caravan air conditioner. They provide both cooling and heating, making them an efficient all-in-one option. These systems are great for handling the varying temperatures of Australian travel.
Dometic FreshJet Series
Some units feature inverter technology, like the Dometic FreshJet Series. This ensures energy efficiency and smooth operation. It's a great option for off-grid setups or when using a generator.
Heating element systems are less relevant, as modern units use more advanced methods. None of your products rely on this older technology, so it doesn't need much focus.
Key Factors to Consider When Buying
Caravan Size and Air Conditioner Capacity
The size of your caravan affects the cooling capacity you need. Smaller caravans up to 5 metres often require 2 to 2.5kW units. Larger caravans may need air conditioners with a capacity of 3kW or more for effective cooling and heating.
Power Consumption
Out of all the caravan appliances, the air conditioner uses the most power. Your power source plays a big role in choosing the right air conditioner. Most caravans are equipped with mains pass-through for powered sites. If you’re camping somewhere without power, you’ll need a reliable setup. Lithium batteries or a good generator can keep everything running smoothly. Make sure the air conditioner matches your power system for smooth operation.
Weight and Dimensions
Air conditioner weight can impact your caravan's stability and payload. Rooftop models add height and weight, so check your van's roof capacity. For under-bunk units, ensure there's enough space inside without losing too much storage.
Noise Levels
Quiet operation is important, especially if the unit is near sleeping areas. Many modern air conditioners are designed to minimise noise, making them more comfortable to use at night.

Maintenance and Troubleshooting
General Maintenance Tips
Keeping your air conditioner in top shape is simple with regular care. Clean the filters and air ducts to prevent dust and debris from affecting performance. Most units have filters that are easy to remove and rinse. Check for leaks or any visible damage to the components. If you spot any issues, address them early to avoid costly repairs. Regular maintenance will keep your air conditioner running efficiently and extend its lifespan.
Common Issues and Solutions
It's normal for air conditioners to face occasional problems. Noise or inconsistent cooling are common complaints. If your unit is noisy, it might be due to loose parts or blocked vents. Tighten any loose screws and clear obstructions to fix this. Inconsistent cooling or heating may be caused by a dirty filter or a reset issue. Clean the filter and try resetting the unit using the instructions in the manual. If the problem persists, it's best to contact a professional for help. Avoid DIY repairs for complex issues as they may void your warranty.
Common Questions on Buying a Caravan Air Conditioner
What size air conditioner do I need for a caravan?
The size of the air conditioner depends on your caravan's length. For caravans up to 5 metres, a unit with 2 to 2.5kW is usually enough. Larger caravans, up to 7.5 metres, may need 3kW or more. Always check the manufacturer's recommendations to ensure the unit is powerful enough for your space.
Can I run my air conditioner on solar power or a generator?
Yes, but it depends on the unit and your power setup. Many air conditioners can run on a generator, but you'll need one with enough wattage to handle the inrush current. Solar power can work with a battery system as long as your inverter is large enough. Check your air conditioner's power requirements and match them with your generator or inbuilt system.
What's the best type for a pop-top caravan?
Under-bunk air conditioners are a popular choice for pop-top caravans. They don't add weight to the roof and save space up top. Rooftop units can also work if the roof is reinforced and can support the weight. Always consult your caravan's specifications before making a decision.
Do caravan air conditioners need regassing?
No, most modern caravan air conditioners are sealed systems that don't require regassing. If your unit isn't cooling well, the problem is likely a dirty filter or another maintenance issue. If you suspect a refrigerant issue, contact a professional. They can inspect the system and fix any leaks.
The Difference between a Caravan Air Conditioner and a Portable Air Conditioner
Caravan air conditioners are built for on being the road. They handle rough conditions and keep your caravan cool or warm while travelling. They fit neatly on the roof or under a bunk, saving valuable space inside.
Portable air conditioners are not made for caravans. They take up floor space and need a vent for hot air, which can be a hassle. They are less durable and less efficient for travel. If you want something reliable and practical for your caravan, a caravan air conditioner is the better choice.
