A portable air conditioner is the cooling you buy when a split system isn't an option: renters, upstairs rooms, and homes where summer arrived before the electrician could. They all cool and they all hum; the three below are the ones whose owners accept the trade happily.
1. Best Overall: DeLonghi PAC EM93K Silent 2.6kW
DeLonghi's Silent model is the quietest serious unit in the class, and its 42 owners rate it 4.4, the best score among the big-brand portables. The 2.6kW output cools a bedroom or study properly, and the low-speed night mode is the feature the name promises.
At around $900 it's the premium pick for sleepers. Silent is relative in this class: it's the difference between conversation-level and lawnmower, not actual silence.
What We Like:
- Quietest in class
- Real night mode
- 2.6kW bedroom power
What We Don't Like:
- Quiet, not silent
2. Best Value: Shinco 2.6kW 9000BTU
The Shinco delivers the same 2.6kW class for around $310, and 290 Amazon owners average 4.4 stars. It cools, dehumidifies and vents through the included window kit, at a third of the De'Longhi's price.
The compressor note sits louder than the Silent's, which matters at 2am and not at 2pm.
What We Like:
- Around $310
- Dehumidifier mode
- Window kit included
What We Don't Like:
- Louder compressor
3. Best Budget: Solt 2.56kW
Solt's unit is the cheapest path to refrigerated cooling at the retailer, around $260, with 139 owners averaging 4.2. It does the job in bedrooms and home offices with the simplest controls in the group.
Build and noise sit at the price point, and the hose kit prefers sliding windows, which is worth checking against your frames.
What We Like:
- Around $260
- Simple controls
- Light to move
What We Don't Like:
- Budget-grade noise
Other options worth a look
- Split systems — a licensed install starts near double the DeLonghi's price and outperforms every portable on noise and running cost. Portables win on tenancy and tomorrow-delivery, which is exactly their place.
How to pick a portable air conditioner
Size to the room, honestly. 2.0 to 2.6kW suits bedrooms and studies; open-plan living wants 3.3kW-plus and even then works hardest on the worst days. An undersized unit runs flat-out and disappoints.
The hose is non-negotiable. Every refrigerated portable vents hot air through a window kit. The no-hose devices sold alongside them are evaporative coolers, a different machine for dry climates only.
Plan for the water. Modern units evaporate most condensate out the hose, but humid weeks still fill the tank. A unit with a drain hose option saves carrying trays through the loungeroom.

FAQs
Why is my portable air conditioner not cooling?
Nine times in ten it's the hose: kinked, too long, or radiating heat back into the room uninsulated. Short, straight and lagged is the whole fix, along with sealing the window kit gaps.
How much do they cost to run?
Around 30 to 40 cents an hour at typical rates for the 2.6kW class. The thermostat cycling means real bills land well under the worst-case maths.
