The Owner's Insights on the myCOOLMAN 3kW Roof Top Air Conditioner
Three kilowatts of cooling and three kilowatts of heating in one roof unit. That's the part people miss: it isn't just an air conditioner, it's the thing that keeps the van liveable at 5am in the high country as well as 2pm in the Kimberley.
The compressor is inverter-style, which is why it draws 1,200W while cooling rather than the 2,000W-plus a conventional roof unit pulls. On a battery, an inverter or a small generator, that difference decides whether you can run it at all.
Two numbers to check before you order: it's 35.8kg installed and 225mm tall on the roof, and it fits a standard 360 x 360mm or 400 x 400mm cutout with roof thickness from 20 to 100mm.

Why the inverter compressor is the whole argument
A conventional roof air conditioner runs its compressor flat out or not at all, which means a big startup surge and a lot of current whenever it's on. An inverter compressor varies its speed to match the load, so it draws what it needs rather than everything it can. At 1,200W input while cooling, this one is within reach of a decent battery and inverter setup or a modest generator. A conventional unit at the same output usually isn't, and that's the difference between air conditioning off-grid and air conditioning only on a powered site.
Heating matters more than people expect
Three kilowatts of heating turns this from a summer item into a year-round one. Anyone who has woken up at 5am in the high country, or on the coast in July, knows the cold is the harder problem: you can strip off in the heat, but a cold van at dawn just gets you up. Having both in one roof unit also saves you fitting a separate diesel heater, its fuel tank and its exhaust.
Check your roof before you order
Three things to measure. The cutout: it suits a standard 360 x 360mm or 400 x 400mm opening, so if you're replacing an existing unit yours is probably one of those. The roof thickness: 20 to 100mm, which covers most vans and caravans. And the footprint: 1,107 x 718mm on the roof, so check it clears your hatches, solar panels and aerials. Ring the store on 03 7056 6732 with your van's details if you're not sure.
Thirty-five kilos on the roof is a real consideration
Installed weight is 35.8kg, and it all sits high on the vehicle. That's payload you need to have, and it raises your centre of gravity. On most caravans and full-size vans it's a non-issue and it's what everyone does. On a light camper trailer or a pop-top with a marginal roof structure, get the installer to confirm the roof can carry it before anything gets cut. It's also a two-person lift onto a roof, so this is a job for a fitter rather than a Saturday.
How loud is it really?
myCOOLMAN don't publish a decibel figure for this unit, so we won't quote one. What we can tell you is what the design suggests: an inverter compressor that runs at part speed most of the time is inherently quieter than one cycling on and off at full power, because it isn't constantly starting and stopping. If noise at night is the deciding factor for you, ring the store on 03 7056 6732 and we'll get a figure from myCOOLMAN before you commit.
What's Included
- myCOOLMAN 3kW roof top air conditioner
- Bluetooth app control
- Standard roof mounting hardware
What's Not Included
- Installation
- Roof cutting or reinforcement
- Wiring to your 240V circuit
- A soft start module, which isn't needed
Installation isn't included and isn't a DIY job for most people: it means cutting the roof, sealing it properly and wiring into your 240V circuit. Budget for a caravan fitter, and get them to confirm your roof can carry 35.8kg before anything is cut.
Not Sure Which Roof Top Air Conditioner Suits You?
The myCOOLMAN 3kW suits you if you want cooling and heating in one roof unit, and your setup runs on batteries, an inverter or a modest generator where the 1,200W draw matters. It's the wrong pick if your roof can't carry 35.8kg, or if you want cooling you can move between a tent, a van and a rooftop, where a portable unit like the Zero Breeze Mark 3 is the answer. Call the store on 03 7056 6732, or send an SMS to 0476 330 590 with your van's details.
