The best portable air conditioner to hire for summer depends on the space, heat load, cooling capacity and available power supply. AirXpress Hire offers seven portable AC options, ranging from 5kW commercial and industrial units to a 10kW commercial model. Comparing their capacities, applications and power requirements can help you choose suitable temporary cooling equipment.
Australian summer heat can make a comfortable workspace feel unbearable, especially when existing air conditioning struggles to keep up. Hiring a portable air conditioner can provide extra cooling without committing to a permanent installation.
But choosing the right unit isn’t just about picking the highest kW rating. Power requirements, heat levels and the space being cooled all matter.
Below, we compare seven portable air conditioners available from AirXpress Hire, highlighting their key features and practical uses to help you narrow down the right option for your needs.
7 Best Portable Air Conditioners to Hire in Australia
1. 5kW Commercial Portable Air Conditioner
The 5kW Commercial Portable Air Conditioner is a cooling-only unit designed for flexible use across commercial and temporary environments. Its compact dimensions of 105 × 60 × 50 cm make placement and relocation easier when cooling requirements change.
The unit provides 5kW of cooling output and uses a standard 10-amp power point. AirXpress Hire lists applications including offices, retail spaces, events, medical rooms and construction offices. It may also suit targeted cooling in a specific work area, depending on the heat load and surrounding conditions.
This option is worth considering when you need portable cooling without the electrical requirements of a larger industrial unit. Before hiring, check that the available space, power supply and exhaust arrangement suit the equipment.
2. 5kW Industrial Portable Air Conditioner
The 5kW Industrial Portable Air Conditioner provides the same nominal cooling capacity as the commercial model but is configured for industrial and commercial applications.
It operates from a standard 10-amp power point and has listed dimensions of 105 × 68 × 50 cm. Its product specifications include a condensate tank, while the listed features include distribution boards, extension leads and digital controls.
Potential applications include server rooms, offices, manufacturing areas, retail spaces and warehouse spot cooling. It can be a practical option when cooling needs to be directed towards a particular area rather than an entire building.
Although both 5kW models have the same rated cooling output, their features and intended applications differ. The choice should depend on the working environment, installation requirements and available power rather than the model name alone.
3. 6kW Commercial Portable Air Conditioner
The 6kW Commercial Portable Air Conditioner offers a step up in cooling capacity for applications that may require more output than a 5kW unit provides.
AirXpress Hire lists this model as suitable for rooms measuring approximately 20–42 square metres. That range is a starting point, not a guarantee of performance in every space. High ceilings, direct sunlight, poor insulation, occupancy and heat-producing equipment can all increase cooling demand.
The unit includes an LCD display and remote controller, allowing users to monitor and adjust its operation. Its listed applications include offices, retail spaces, events, small server rooms and manufacturing spot cooling.
For a temporary office, retail area or enclosed event space, this model may be worth comparing with the 5kW options. Check the actual heat load and installation conditions before deciding whether the extra capacity is necessary.
4. 6.5kW Industrial Portable Air Conditioner
The 6.5kW Industrial Portable Air Conditioner provides additional cooling capacity while retaining a standard 10-amp plug according to its product listing.
Its features include temperature controls, lockable castor wheels, extendable cold-air ducts and an 11-litre condensate tank. These details matter when the unit needs to be moved between locations or directed towards a particular work area.
AirXpress Hire lists applications such as offices, warehouses, server rooms, retail spaces and manufacturing spot cooling. The extendable ducts can be useful where cooled air needs to be directed towards a designated area, subject to the setup and manufacturer’s operating requirements.
This model may suit a workplace that needs more cooling output than a 5kW unit can provide but still requires a portable system with a standard power connection. Confirm the required airflow, positioning and drainage arrangements before hiring.
5. 7.5kW Industrial Portable Air Conditioner
The 7.5kW Industrial Portable Air Conditioner is another option for environments with a higher cooling demand. Its listed cooling capacity is 7.5kW, with an electrical supply of 240V and current consumption of 13.5 amps.
The product specifications also list an airflow range of 880–960m³/h. Airflow and cooling capacity are related but measure different things: capacity describes the amount of heat the unit can remove, while airflow indicates how much air it moves. Both are relevant when deciding whether cooled air can reach the area that needs it.
This model may be suitable for targeted cooling in commercial and industrial spaces where a smaller unit is unlikely to provide sufficient output. However, it should not automatically be treated as suitable for a particular room size without considering the room’s heat load, ceiling height and layout.
Before arranging hire, confirm the electrical connection required at the site and whether the unit’s air delivery suits the intended application.
6. 9.5kW Industrial Portable Air Conditioner
The 9.5kW Industrial Portable Air Conditioner is designed for applications requiring substantially more cooling output than the smaller models.
Its specifications list a 9.5kW cooling capacity, current consumption of 20 amps and airflow between 1,317 and 1,498m³/h. Features include a two-speed fan, temperature controls, a 24-hour timer, automatic restart after a power interruption and a self-diagnostic control system.
Potential applications include offices, retail spaces, events, server rooms, data centres and manufacturing spot cooling. It may be worth considering where equipment or other heat sources create a demanding local cooling requirement.
Power availability is particularly important with this model. The product listing identifies a 20-amp requirement, so a standard outlet should not be assumed to be suitable. Confirm the electrical setup with the hire provider before installation.
7. 10kW Commercial Portable Air Conditioner
The 10kW Commercial Portable Air Conditioner is the highest-capacity option in this comparison. It provides 10kW of cooling and is designed for applications that may require a different installation arrangement from smaller portable spot coolers.
The unit uses three-phase power, with the product listing specifying a 20-amp three-phase supply. It also includes condensate pumps, digital controls and extension leads. Its listed applications include plant rooms, external installations, offices, retail spaces, events and directing cooled air through ducting to a required location.
This model may be suitable where cooling needs to reach a particular area through a ducted arrangement or where a higher-capacity unit is required. Its larger output does not automatically make it the right choice for every room, however. The installation, power supply and heat load must all be considered.
Because the electrical requirements differ from those of the smaller models, check the site’s available supply before arranging delivery.

Choosing the Right Portable AC
The most suitable unit depends on more than the cooling capacity printed on its specifications. Consider the following factors before making a decision.
- Cooling demand: Room dimensions, ceiling height, insulation, sunlight, occupancy and heat-generating equipment all influence the required capacity.
- Power availability: Check whether the site has the correct outlet, current rating and phase supply for the selected model. Larger units may need a dedicated connection.
- Air delivery: Consider whether the unit will cool an occupied zone directly or needs to deliver air through ducts. Positioning can affect how evenly the space cools.
- Ventilation and exhaust: Portable refrigerated air conditioners generally need an exhaust duct to discharge hot air outside. The installation must allow this without letting discharged heat return to the cooled space.
- Drainage and access: Check condensate management, doorway clearance, floor space and access for moving the unit into position.
- Hire duration: A short-term event, temporary office and ongoing equipment-cooling requirement may call for different arrangements.

It’s also worth considering the exhaust configuration. The Australian Government’s YourHome heating and cooling advice explains that portable air conditioners need to discharge hot condenser air outside and that poorly sealed exhaust openings can allow heat to enter the room. This makes installation an important part of getting the expected performance from a hired unit.
Why Hire a Portable AC?
Hiring can be useful when cooling requirements are temporary or likely to change. For example, a business may need additional cooling during a heatwave, an event organiser may require equipment for a short booking, or a workplace may need a temporary arrangement while a permanent system is repaired.
Hiring also avoids purchasing and storing a unit that may only be needed for part of the year. It gives you the opportunity to select equipment based on the immediate application, although the overall cost depends on the hire period, delivery, setup and any additional requirements.
Portable air conditioning is not always the best solution for every setting. The Australian Government’s heating and cooling information notes that portable air conditioners can be less effective and less efficient than installed systems. For a long-term requirement, it may be worth comparing temporary hire with a permanent cooling solution.
For temporary or targeted cooling, the key is choosing equipment that matches the actual demand and can be installed correctly.
FAQs
Which portable air conditioner is best for summer?
The right model depends on the cooling load, available power and how the cooled air needs to be delivered. A 5kW unit may suit some targeted applications, while higher-capacity models may be more appropriate for demanding commercial or industrial environments.
What is the difference between commercial and industrial portable air conditioners?
The labels generally reflect the intended application and equipment configuration, but they do not tell the whole story. Compare the cooling capacity, airflow, power requirements, controls and installation features of the individual models.
What size portable air conditioner should I hire?
Start with the room dimensions, then account for ceiling height, sunlight, insulation, occupancy and equipment heat. The required capacity can vary considerably between spaces of the same floor area, so seek advice if the cooling load is uncertain.
Do portable air conditioners require a special power supply?
Not all models have the same electrical requirements. Some AirXpress Hire units use a standard 10-amp power point, while higher-capacity options may require 20-amp or three-phase power. Confirm the supply before booking.
Can I hire a portable air conditioner for temporary commercial cooling?
Yes. Portable units can be used for suitable temporary applications such as offices, retail spaces, events, construction offices and targeted equipment cooling. The appropriate model depends on the environment, heat load and installation requirements.
Final Thoughts
AirXpress Hire’s portable air conditioner range covers several cooling capacities, from 5kW units to a 10kW commercial model. The differences in power supply, airflow, controls and air delivery are just as important as the rated cooling output when deciding which unit to hire.
Before choosing, assess the space and its heat load, check the available electrical supply, and plan how the unit will exhaust hot air and manage condensate. These checks can help you avoid hiring equipment that is unsuitable for the site.
