Flexible, self-contained cooling for rental properties, apartments, garages, home offices, and any space where a permanent installation is not possible.
A portable air conditioner is a freestanding, self-contained cooling unit on castors that can be moved from room to room as needed. Unlike split systems, window units, or ducted systems — which all require some degree of permanent installation — a portable air conditioner requires no mounting, no drilling, no refrigerant pipe installation, and no licensed trade work to set up.
The unit contains all components required to cool the air — compressor, condenser, evaporator, expansion valve, and fans — within a single freestanding cabinet. The only external connection needed is a flexible exhaust hose that carries hot air outside through a window kit fitted into a standard window opening.
Most models also include additional functions such as a built-in dehumidifier, fan-only mode, sleep mode for quieter overnight operation, and a digital thermostat with a programmable timer. Portable units are available in a range of capacities to suit different room sizes.
Rentals, apartments, garages, temporary spaces, guest rooms, rooms without split system access
No installation required — roll out, fit window kit, connect exhaust hose, plug in, done
Moves from room to room, property to property — stored away in winter
Must be vented outside via a window or vent opening — hose length is fixed
Collects moisture during cooling — managed via drain tank, auto-evaporation, or drain hose
Same refrigeration cycle as split systems and ducted systems — delivered in a completely self-contained, freestanding format.
Warm room air is drawn through the intake grille and passed over the cold evaporator coil. Refrigerant absorbs heat from the air, cooling it before the fan blows it back into the room. The heat is carried to the condenser section and expelled outside via the exhaust hose.
The hot air from the condenser exits through a flexible exhaust hose connected to a window kit fitted into a standard window opening. The kit seals around the hose to prevent hot outside air from re-entering the room. A straight, short hose run maximises efficiency.
Single-hose units use room air to cool the condenser — creating slight negative pressure that can draw warm air in. Dual-hose units draw fresh outside air for the condenser through a second hose, eliminating the negative pressure issue and improving efficiency in well-sealed rooms.
Moisture extracted from the room air during cooling must be managed — collected in a drain tank you empty manually, expelled through the exhaust hose via auto-evaporation, or drained continuously through a drain hose. Check condensate requirements before purchasing.
Understanding the different types helps you choose the most appropriate unit for your room, climate, and usage requirements.
The most common type. One exhaust hose vents hot air outside. Simple to set up, compact, and the most affordable option. Best suited to rooms that are not tightly sealed, or where maximum efficiency is less important than convenience.
Most CommonTwo hoses — one draws fresh outside air to cool the condenser, one exhausts heated air outside. More efficient in well-sealed rooms. Eliminates the negative pressure caused by single-hose units. Slightly larger and more expensive than equivalent single-hose models.
More EfficientIncludes a dedicated dehumidification mode that removes excess moisture from the air without necessarily providing significant cooling. Useful in rooms where high humidity is the primary comfort issue — coastal areas, basements, or laundry rooms.
Multi-FunctionHeavy-duty units designed for commercial, industrial, or large-space applications — server rooms, construction sites, event spaces, temporary offices, and warehouses. Available in significantly higher capacities than residential units, often designed for continuous heavy-duty operation.
Commercial UsePortable air conditioners offer a unique combination of flexibility, accessibility, and convenience that fixed systems simply cannot match.
No drilling, no wall modifications, no refrigerant pipe installation, no licensed technician needed. Roll it out, fit the window kit, plug in — operational in minutes.
Move from room to room as needed, take to a different property, or store away during winter. This level of flexibility is not possible with any fixed air conditioning system.
For tenants who cannot make permanent modifications due to body corporate restrictions, landlord refusal, or lease conditions — a portable unit requires no modification and can be used in virtually any rental property.
All components are in one self-contained cabinet. No outdoor compressor needed. Particularly relevant for apartments on upper floors, heritage buildings, and properties where placing an outdoor unit is not possible.
For guest rooms, seasonal spaces, garage workshops, or temporary offices — a portable unit provides cooling without the ongoing cost of a permanent system sitting idle most of the year.
Supplements an existing fixed system — cools a specific area the main system does not reach effectively, provides extra capacity during extreme heat, or serves a room added since the original system was designed.
Generally less expensive to purchase than a split system installation and significantly less than a ducted system. An accessible option where the budget for permanent air conditioning is limited.
Being well-informed means understanding the limitations as well as the benefits — so you can make the right decision for your specific situation.
Generally less energy-efficient than an equivalent split system. For rooms used daily throughout summer, the higher running cost may outweigh the lower purchase price over time.
The hose must reach an outside vent — typically a window — restricting where the unit can be positioned. The window must remain partially open while the hose exits.
Because all components — including the compressor — are inside the room, there is no way to isolate mechanical noise from the occupied space. Noisier than modern split systems.
Depending on the model, managing condensate requires periodic attention — emptying a drain tank or connecting a drain hose.
Generally most effective in rooms up to approximately 20 to 35 square metres. For larger rooms or open-plan areas, a fixed system will deliver significantly better results.
Choosing the correct capacity is important. An undersized unit will run continuously without achieving comfort. An oversized unit provides unnecessary cost without proportionate improvement.
Capacity is measured in kilowatts (kW) or BTU. The table below is a general guide only — actual cooling performance depends on many room-specific factors. Contact us for personalised advice.
| Capacity | Room Size | Best For |
|---|---|---|
| 2.0–2.5kW | Up to 15–20m² | Small bedroom, study, nursery |
| 3.5kW | Up to 25–30m² | Standard bedroom, small living room |
| 4.5kW+ | Up to 35m² | Larger room, home office, garage |
Ceiling Height — Higher ceilings increase the air volume requiring cooling
Insulation — Poor insulation means the unit must work harder to maintain temperature
Windows & Sun Exposure — Large windows facing west or north increase heat load significantly
Heat-Generating Appliances — Computers, TVs, ovens, and lights all add to cooling load
Occupancy — More people in the room increases the heat load the unit must handle

No professional installation needed — but correct setup is important for optimal performance, safety, and condensate management.
Place close to a window or vent where the exhaust hose can exit without excessive bending. The shorter and straighter the hose run, the more efficiently the unit will operate.
Fit the sliding or adjustable panel into the window opening. Ensure gaps around the panel are sealed to prevent hot outside air from re-entering the room around the edges.
Connect from the rear of the unit to the window kit outlet. Ensure the hose is not kinked, twisted, or bent at sharp angles — this restricts airflow and reduces cooling efficiency.
Locate the drain tank and understand how to empty it — or connect the continuous drain hose if the model supports it. Know the water level indicator so you are not caught off-guard.
Leave adequate clearance around the unit for airflow to the intake and exhaust grilles. Blocking the grilles reduces efficiency and can cause the unit to overheat and shut down.
Use the timer to pre-cool the room before you arrive. Set a comfortable but not excessively cold temperature to minimise running costs without sacrificing comfort.
The air filter should be cleaned every two weeks during heavy use. A clogged filter restricts airflow, reduces efficiency, and can cause the unit to overheat. Most portable units have a removable filter panel accessible without tools — wash under running water and allow to dry before reinserting.
The condensate drain tank should be emptied regularly if the unit does not have auto-evaporation. Most units have a water level indicator and shut down automatically when full to prevent overflow.

Honest answers to the most common questions about portable air conditioners.
No — in energy efficiency, cooling capacity, and noise level, a portable unit will not match a properly sized and installed split system. However, for situations where a split system cannot be installed, a portable unit provides a reasonable and practical alternative.
Portable air conditioners cool one room at a time. Because the unit must remain connected to the exhaust hose exiting through a specific window, it cannot simultaneously cool multiple rooms. You can move it to a different room, but this requires repositioning the hose.
Yes — all refrigerated portable air conditioners must be vented via the exhaust hose. Without it connected, the unit will warm the room rather than cool it because the condenser heat has nowhere to go. Always connect the hose before operating.
A portable air conditioner typically consumes more electricity per unit of cooling than an equivalent inverter split system. For frequent regular use over a full summer season, the difference in running costs can be significant — another reason to consider a split system when a permanent installation is possible.
Yes — all refrigerated portables extract moisture from room air during cooling. Management depends on the model — drain tank (manually emptied), auto-evaporation through the exhaust hose, or continuous drain connection. Always check condensate requirements before purchasing.
The exhaust hose needs to vent outside — most commonly through a window. In rooms without a window, options include a drop ceiling space, a wall vent, or a dedicated duct penetration through a wall or door. Call us for advice specific to your room's configuration.
