The Owner's Insights on the FJZ7 Pro
Most people ringing us about a caravan air conditioner don't need the biggest one. They need the one that suits the van they've actually got. That's this one.
The Pro sits in the middle of the FJZ7 range at 3,400W. It's the all-rounder, and for a typical touring van in a typical Australian summer it's the one you want.
It's 242mm tall and 36kg, so it's 41mm lower and 2kg lighter than the Plus. If your roof load is getting tight, that's worth knowing.
Same platform as the rest of the range. Inverter compressor, brushless fans, Adaptive Power Mode, reverse-cycle heating.
Same honest catch too. You're buying the roof unit on its own. Budget for the ADB and for a qualified installer, because this is a hole cut through your roof.
Why You'll Love the FJZ7 Pro
- 3,400W of cooling. The middle of the range, and enough to keep your van cold through a normal summer.
- Adaptive Power Mode. Cap the current draw in the Dometic Power App so a small hookup doesn't trip.
- Variable-speed inverter compressor. It trims its speed to hold your temperature rather than slamming on and off.
- Lighter and lower than the Plus. At 36kg and 242mm tall it asks less of your roof and your load rating.
- Reverse-cycle heating built in. The same unit warms the van, so you're not carrying a second heater for shoulder season.
- R32 refrigerant. Lower global warming potential in your system than the refrigerant Dometic used before.

Why You Should Consider a Dometic Caravan Air Conditioner
Dometic has been building rooftop air conditioners for Australian caravans for decades, and the service network here is the real argument for putting one on your van. Parts, dealers and service agents are spread right across the country. On something bolted through your roof, that support outlasts the price difference. See the rest of the Dometic range.

What installing a Dometic caravan air conditioner involves
This isn't a bolt-on job. The unit sits over an opening cut through your roof, and the ADB clamps up from inside the ceiling. If your van already runs a Dometic rooftop unit, your existing opening may suit it. If it doesn't, someone has to cut one and seal it properly. Get that wrong and you've got a leak over your bed. Use a caravan repairer or a licensed electrician. Ring the store and you'll get pointed at a dealer near you.
Running the FJZ7 Pro off batteries and solar
Can you run it off your own power? With the right system behind it, yes. The Pro draws up to 6.1 amps at 240V flat out, so call it around 1.5kW through an inverter. That wants a decent lithium bank and real solar on your roof, not a token panel. Adaptive Power Mode is the part that makes it manageable. You set a current ceiling in the app and the unit trims output to stay under it. Less current, less cooling. That's the trade.
Reverse-cycle heating on the FJZ7 Pro
The Pro heats as well as cools, off one button on the ADB. For a cold start in the high country it beats you getting up to light a diesel heater. It won't match one in serious cold though, because a heat pump gives up output as the outside air drops away. Dometic lists an operating range of minus two to 52 degrees. If your winters are genuinely cold, treat this as a bonus rather than your main heating.
FJZ7 Pro versus the Plus and the Lite
All three share the platform, so your choice comes down to size and roof space. The Lite is 3,000W, 30.6kg, on a 752 x 702mm footprint. The Pro is 3,400W and 36kg. The Plus is 4,000W and 38kg. The Pro and the Plus share the same 1090 x 700mm footprint, so stepping between those two costs you nothing off your roof. Going down to the Lite buys you back a lot of room for panels.

Not Sure Which Caravan Air Conditioner Suits You?
Here's the short version. Big van, hot country, a few bodies inside: step up to the FJZ7 Plus at 4,000W. Short van, or roof space you'd rather give to solar: the FJZ7 Lite is 3,000W on a much smaller footprint. The Pro is the one that suits most vans in between. The honest catch on every rooftop unit is the same, and it's the install. This means cutting an opening through your caravan roof and sealing it properly, which is work for a qualified caravan repairer or a licensed electrician. True Gear sells the gear and doesn't install it. Dometic Australia covers air conditioners for three years against faulty materials and workmanship, and your rights under Australian Consumer Law sit alongside that.
