What is the best temperature to set the air conditioner?

Answer 1

Most experts would say that a temperature between 73 to 79 degrees Fahrenheit with a humidity between 40 and 60% is recommended in the summer. But perhaps to follow that to the letter is too simplistic because some people can get really uncomfortable when it becomes humid and the humidity might be around 60%.

Some air conditioning engineers have gone a step further and instead of referring to percent humidity they refer to something called Wet Bulb temperature and they say that even a 68 degree Wet Bulb temperature is acceptable, which would make the atmosphere in the room even stickier than most people are used to. I tried that and it didn't work for me. I will mention the website where those engineers' (they are called ASHRAE) recommendations are if you want to read them. Their website is http://www.ashrae.org/File%20Library/docLib//Public/2003691613_347.pdf I hope a link works here.

What I have found for myself is that a temperature below 76 degrees is best with the humidity much below 60%, even 58% for example is good, but a humidity above 60% can be uncomfortable.

Another thing is that many room air conditioners have a button or lever that closes or opens the air exhaust. When that air exhaust is closed the air conditioner acts like a dehumidifier and it cuts down the humidity and that is good. But some smaller size air conditioners do not have such an air exhaust button or lever and the air exhaust is always open and it can get quite humid in the room. That is not so good. One thing that someone can do with those small air conditioners is to use the Energy Saver option that they carry sometimes and you may find that there is a lot less humidity in the room that way than if you used more energy. That would be nice.
