Truck refrigeration is a larger investment than van refrigeration, and the price range is wider. A light Isuzu NPR build and a heavy Kenworth B-double are both refrigerated trucks, but the systems, insulation specifications, and costs are entirely different.
This guide breaks down 2026 cost ranges by truck size, explains what drives the price difference, and covers what a complete quote should include.
Cost estimates by truck size
| Truck Category | Example Models | GVM | Estimated Cost (Supply + Install) |
|---|---|---|---|
| Light truck | Isuzu NPR, Fuso Canter, Hino 300 | 3.5t to 6t | AUD $12,000 to $22,000 |
| Medium truck | Isuzu NQR, Fuso Fighter, Hino 500 | 6t to 12t | AUD $20,000 to $35,000 |
| Heavy truck | Isuzu FRR, Kenworth T360 | 12t and above | AUD $30,000 to $55,000+ |
These estimates cover a standard single-temperature chilled build (0°C to +8°C) with a quality-brand refrigeration unit and polyurethane foam insulation. Frozen builds (-18°C and below) carry a 25 to 40% premium across all categories. Multi-temperature builds add further to these figures.
What a complete truck refrigeration quote includes
- Refrigeration unit: condenser and evaporator, with the brand and model specified. Daikin, Carrier Transicold, and Thermo King are the main quality brands in Australia.
- Insulation panels: floor, walls, ceiling, and door. Thickness and material should be specified — 60 to 75mm for chilled, 100mm for frozen.
- Interior lining: GRP or aluminium sheet over insulation.
- Door hardware: commercial hinges, seals, and locking mechanism rated for the operating temperature.
- Refrigerant charge: included in all complete installations.
- Electrical wiring: to power the refrigeration unit and cab controller.
- ARCtick-licensed labour: legally required for any work involving refrigerant handling under Australian law.
- Commissioning documentation: setpoint verification and sign-off record.
Factors that push the price higher
| Factor | Typical Additional Cost |
|---|---|
| Frozen build (100mm panels, higher-capacity unit) | +AUD $6,000 to $15,000 |
| Multi-temperature (dual or triple zone) | +AUD $12,000 to $25,000 |
| Self-powered unit (own diesel engine) | +AUD $8,000 to $20,000 |
| Standby power capability | +AUD $1,500 to $3,000 |
| Pre-work on older truck body (rust, structural) | +AUD $1,000 to $4,000 |
| Premium unit brand vs mid-tier | +AUD $3,000 to $8,000 |
Self-powered vs direct drive: the cost difference
Light trucks on metro delivery routes typically use direct drive units that draw power from the vehicle engine. Self-powered units, which carry their own diesel engine and run independently of the vehicle, are standard on long-haul trucks and refrigerated trailers. A self-powered unit on a heavy truck adds AUD $8,000 to $20,000 to the build cost but eliminates cooling loss during extended parking. See the full breakdown in the types of transport refrigeration units guide.
How to get a reliable quote
- Specify the required temperature setpoint, not just ‘refrigerated truck’
- Confirm whether standby or self-powered capability is required
- Ask for the refrigeration unit brand and model number, not a generic description
- Confirm the insulation panel thickness and material in the quote
- Verify the installer holds an ARCtick licence from the Australian Refrigeration Council

Frequently Asked Questions
Does the cost include the refrigeration unit or is that quoted separately?
A complete supply-and-install quote should include the refrigeration unit, insulation, lining, refrigerant, wiring, and commissioning as a single package. If a quote presents the unit and installation as separate line items, confirm the total cost of both before comparing it to other quotes. Auto Frigo quotes the full package as a single itemised document.
How much does a truck refrigeration service cost in Australia?
A standard 6-monthly truck refrigeration service in Melbourne ranges from AUD $350 to $700 depending on the unit size, condition, and any parts required. Services that involve refrigerant top-up carry additional refrigerant cost. Auto Frigo provides fixed-price service agreements for fleet operators to manage this cost predictably.
Is a frozen truck significantly more expensive than a chilled truck?
Yes. Frozen builds require thicker insulation panels (typically 100mm versus 60 to 75mm for chilled), a higher-capacity refrigeration unit, and heavier-grade door seals. On a medium truck, this typically adds AUD $8,000 to $15,000 to the total build cost. The heavier insulation also reduces usable cargo volume by approximately 10 to 15%.
Can I get a truck refrigeration unit financed?
Vehicle fitout financing is available through most commercial equipment finance lenders in Australia. Auto Frigo can provide the itemised quote required for a finance application. Some operators also access instant asset write-off provisions under the Australian Taxation Office rules for business equipment purchases. Confirm the applicable threshold with your accountant for the current financial year.
What warranty applies to a truck refrigeration installation?
Auto Frigo provides a 5-year warranty on all truck refrigeration installations. The refrigeration unit itself carries the manufacturer warranty: Daikin units are typically 2 years parts and labour. The installation warranty and the unit warranty are separate and both should be confirmed in writing before the job is signed off.
