The Stirling ac unit i bought has a diagonal airdliw that seems counterintuitive to how you would set it up in a room and so doesnt seem efficient. it is also extremely noisy for me. we rang the helpline and got no help sadly.

Does the job, easy to use, cheaper than most other portable air conditioners but still quite effective! Glad we purchased this as it has definitely helped to make us feel more comfortable during the hot days and nights.

It worked well for 2 weeks and by working well I mean it actually blew cold air. After 2 weeks, it makes all the noise associated with a cheap portable a/c unit but stopped delivering cold air. I have 2 other Portable A/C Units (different brands) that work extremely well. In terms of the Stirling 12000BTU 3.4kW Portable A/C - I wouldn't recommend you buy one - you can achieve the same result with a $50 fan.

I’ve used this product overnight and it coped without issue.
It’s very simple to use with minimal setting options
When using it during really hot nights it’s not going to make your room feel like a fridge. It will cool it down a bit though but I found this to be the case with having the air con and the ceiling fan running together. It’s also not the best for a bedroom as the cold air was hitting against the bed. When you turn the vents upward it doesn’t blow the air high enough to surround the room efficiently. Also the electrical cable is too short for a product that requires direct connection to a wall socket and not recommended to be connected to a power board or extension cable

Very quiet, very cold air, cools my one bedroom apartment. I use a fan to move the cold air around and raised it on a bookshelf for greater quicker cooling . It still worked as well on a 40° day. As effective as the brand name one my parents bought for double the price.
