Question about Midea Porta Split

My two units are running 24/7 in the current temperatures – and, thanks to surplus solar power and a large home battery, they’re 100% free and carbon-neutral

Add: Otherwise, these things are built to be left on all the time, and they’re covered by a warranty anyway. It’s much worse if you only switch them on briefly every now and then.

You can, but you still have to comply with certain noise control criteria at night; regardless of what everyone else might say, the outdoor unit isn’t particularly quiet. It’s more like a fairly loud fan with a bit of a hum. I’ve got it on my balcony, which is separated from the next balcony only by a concrete partition wall. If you run the unit on the lowest setting, at 22 degrees, I find it just about tolerable. On ‘Silent’ mode at 18 degrees, it’s clearly audible but tolerable during the day. Anything other than ‘Silent’ is actually quite loud; it’s not a proper, quiet split-system air conditioner, but still just a portable split unit.

The good thing is that even on ‘Silent’ it cools quite effectively; of course, it’s not enough to cool my 60m² flat down to 20 degrees – no setting can do that – but it doesn’t get as hot as 28 degrees either. And the energy consumption is really excellent. In ‘Silent’ mode, which cools quite well, it’s 370 watts, which works out at about 70 francs a month for 24/7 operation, and in ‘Silent’ mode set to 22 degrees, it’s actually only around 100 watts… So absolutely nothing…

So: you do need to bear the noise levels in mind to some extent. The manufacturer’s specifications are a bit misleading in this respect, as are most user reviews that describe it as ‘whisper-quiet’.

No, the device will self-destruct after 23 hours and 59 minutes 🤷
