The Coolest Companion on the Road
If you’re travelling through the Aussie outback or parked by the beach in the middle of summer, there’s one thing every caravaner agrees on—you need good air conditioning. That’s where the Air Command Ibis Rooftop Air Conditioner steps in.
Specifically engineered for caravans, the Ibis is a favourite for keeping your mobile home at the perfect temperature, whether it’s scorching hot or bitterly cold. But is it really worth the investment?
Let’s break it down.
What Is the Air Command Ibis?
The Ibis is a reverse-cycle rooftop air conditioner, designed specifically for caravans, RVs, and motorhomes. Manufactured by Air Command (part of the Dometic Group), it has built a strong reputation for reliable performance, energy efficiency, and quiet operation.
The Ibis has evolved over the years, with the Ibis 4 being the latest and most advanced model.
Ibis 3 vs Ibis 4: What’s Changed?
The Ibis 3 was already a solid performer. But Air Command went back to the drawing board and gave us the Ibis 4, which is quieter, lighter, and more efficient.
- Weight: The Ibis 4 is around 10 kg lighter than the Ibis 3. That’s a big deal when it comes to rooftop installations and fuel economy.
- Size: Slimmer and more aerodynamic.
- Noise: Major reductions in compressor and fan noise.
- Efficiency: Better cooling output with less power draw.
In short, the Ibis 4 is a significant upgrade—especially if you’re serious about comfort on the road.
Choosing The Right Generator For Your Caravan Air Conditioner
Cooling Power: Will It Handle the Heat?
The Ibis 4 delivers 2625 watts (9,000 BTU) of cooling power and 3000 watts of heating through a reverse-cycle system. That’s enough to cool or heat a medium to large caravan, even under extreme conditions.
It uses dual-cylinder compressors and soft start technology, which not only improves energy efficiency but makes it gentler on your power supply—especially handy when you’re running off a generator.
Heating Too? Yep, It’s Reverse Cycle
It’s not just for summer. The Ibis works beautifully in winter too.
Thanks to the built-in reverse-cycle heat pump, it pulls warm air into the van just as efficiently as it cools it. No need for a separate heater.
This is a huge bonus for year-round travellers.
Noise: Can You Sleep Through It?
Absolutely.
One of the biggest complaints about older caravan air conditioners was the noise. The Ibis 4 tackles this head-on. It features a twin-cylinder inverter compressor, which drastically reduces operational noise.
- On low fan mode, it’s whisper quiet.
- There’s also a dedicated Sleep Mode that dials everything down for night use.
So yes, you can finally sleep without earplugs.
Power Use and Generator Compatibility
The Ibis 4 draws around 1600 to 2000 watts when cooling and slightly more when heating. Thanks to its soft-start function, it doesn’t need a huge surge on startup.
This means:
- You can run it on a 2400W or 3000W generator.
- A Honda EU22i or similar may manage, but not without risk—especially in hot conditions.
Best bet? Pair it with a quality 2400W+ inverter generator with a high surge capacity.
Installation: Will It Fit Your Van?
The Ibis 4 fits into the standard 360 x 360 mm hatch opening used in most Aussie caravans.
Specs:
- Height: Just 230 mm on the roof
- Weight: Only 40 kg
- Interior ADB: Modern, compact and stylish
It’s a two-piece system: the rooftop unit and the internal air distribution box (ADB). Installation is straightforward for most vans, but unless you’re very handy, it’s best left to a professional.
Controls and Features
You get a sleek remote control with:
- Fan speed control (4 levels)
- Auto mode
- Sleep mode
- Timer
- Temperature setpoints
The display is easy to read, and the thermostat is accurate. Set it and forget it.
Durability: Built for Aussie Conditions
The Ibis 4 is made for Australia.
- UV-resistant casing
- Rust-proof components
- Designed to handle extreme heat, dust, and humidity
It’s engineered to survive off-road adventures, coastal campsites, and inland heatwaves.
And with a 3-year warranty, you’re covered if something goes wrong.
Maintenance: What You Need to Know
Like any air conditioner, the Ibis 4 needs a little TLC.
Basic maintenance includes:
- Cleaning or replacing the internal filters every few weeks (they pop out easily).
- Keeping the rooftop vents clear of leaves and debris.
- Checking the condensation drain system for clogs.
Service it annually and it’ll last for years.
Pros and Cons
Pros:
- Quiet operation
- Lightweight and slim
- Energy efficient with soft-start
- Heating and cooling in one
- Excellent build quality
Cons:
- Price is premium
- Might push the limits of a small generator
- Professional install usually required
Ibis vs. Dometic Harrier: The Showdown
Dometic Harrier Inverter is the Ibis’s main rival. Here’s how they stack up:
| Feature | Ibis 4 | Harrier Inverter |
| Weight | 40 kg | 44 kg |
| Cooling Power | 2625W | 3100W |
| Noise | Very low | Very low |
| Soft Start | Yes | Yes |
| Price | Slightly lower | Slightly higher |
Both are excellent. If you want slightly more cooling grunt, go Harrier. If weight and noise are more important, go Ibis.
What Caravaners Are Saying
Most Ibis owners rave about:
- The whisper-quiet nights
- Fast cooling on 40°C days
- Smooth performance off-grid (with a decent generator)
Common complaints include:
- Can be tricky to install solo
- Not ideal for very small or pop-top caravans due to size and weight
Final Verdict: Is the Ibis Worth It?
If you’re after a high-performance, quiet, and efficient rooftop air conditioner, the Air Command Ibis 4 should be at the top of your list.
It’s not the cheapest. But it’s reliable, smart, and made for the wild Aussie climate. Whether you’re doing the Big Lap or weekend trips, the Ibis 4 will keep you comfortable every step of the way.
