Why the Cool-J HB9000 PLUS Stands Out
The HB9000 PLUS is a thoughtfully engineered underbunk air conditioner that fits neatly into smaller spaces on vehicles up to 6.5 metres, freeing up your interior for living space. Its reverse cycle technology not only cools efficiently in summer but also provides effective heating during cooler months — including an additional heating element that ensures warmth in low temperatures.
The revamped one-piece EPP frame significantly cuts down vibration and noise, creating a more serene environment when parked or driving. Meanwhile, the updated GMCC compressor balances impressive energy efficiency with dependable performance to protect your vehicle’s power reserves.
Control your climate easily with the unit’s built-in WiFi functionality. Adjust settings, set timers, or operate night mode remotely via smartphone, making the HB9000 PLUS as smart as it is practical.
Best for
- Owners of caravans or motorhomes up to 6.5 metres seeking quiet, energy-conscious climate control
- Campers wanting flexible heating and cooling with smart, remote control convenience
- Travellers valuing low noise and vibration for a restful trip
- Anyone requiring reliable heating during colder months without sacrificing power efficiency
Not ideal for
- Vehicles longer than 6.5 metres or with larger cabin volumes that need higher-capacity systems
- Those wanting an all-in-one unit with included ducting (this unit requires separate duct purchases)
- Self-installers who do not intend to use licensed electricians for compliant electrical connections
Installation and Accessories
The air conditioner is sold without ducting, so choosing duct lengths (5m or 10m) and outlet colours (white or black) to suit your setup is necessary and can be purchased separately. Installation instructions are provided with the unit, but note that final electrical connections must be completed by a licensed electrician to Australian standards AS/NZS3000 and AS/NZS3001 for safety and compliance.
We recommend reviewing accessory options and installation requirements on the merchant page before purchase to ensure your setup runs smoothly.
