The trouble with this is that the air is then full of moisture. If you live in a humid climate, your air is already full of moisture so a bit more doesn't make things better – just more humid. Having moisture laden air constantly blowing around the room means that mould can easily develop, especially up in those high corners. A mouldy home is not a healthy home and it takes a lot of extra work to constantly clean it off.
There is no temperature control with an evaporative air conditioner, what you get at first is what you keep on getting.
And neither can they be reversed to provide heating in the winter. Instead, they have to be taken out and stored somewhere so that you can fit your heater in.These problems are still present today, but there are some occasions where an evaporative air-conditioner will be just the thing. In a dry, hot climate it will provide that extra moisture to help you breathe better and feel more hydrated. When travelling in a caravan or motor home they can be good because you don't have to install them. Or if you live in a small flat or unit they can also be good as they cool down a smaller room much more efficiently. So it is up to you to decide whether an evaporative air-conditioner is right for you.
