“What temperature should I set my cooling?”
Between 70 and 75 is kind of what I have seen in homes. Some people like 72, some people like 75 or 76, whatever is comfortable for you.It really depends. If you look up the Department of Energy on what you should be setting your home at they will tell you to set it at 78.
The problem I also have seen is that, this is a big problem with the realty companies because every time I have talked to them they tell people when they sell their homes to set it at 80, 85 since no one is living in the house. Wait a minute that is going to be a problem, we are in southeastern North Carolina and it is hot and humid. You need to dehumidify that space and cool that space a lot more at 85 and 80. I wouldn’t go higher than 78. If you are leaving the home for a period of time, I would keep it at 78 that way it will come on and it will dehumidify. Otherwise you are going to have a lot of humidity in the house, things are going to start growing, and that is going to be a whole other problem outside of the energy bills you are trying to save.
Someone I know recently replaced their thermostat from a slide bar to a digital thermostat. The problem with going from a slide bar thermostat to a digital thermostat is that the digital is reading accurate temperatures and the slide bar is not. So, the slide bar might be reading at 75, digital might be at 70. Don’t get hung up too much on the numbers, whatever is comfortable for you and your home is what you need to set it at. If you are good with 70 then go with 70, if you like 75 go with that. Me, myself, I keep it about 73 or 74 and then when I go to bed it gets really cold so I go down to 71 or 70 just because that is what I like. Whatever you like you need to keep it at but just be aware that when you read, or listen to people, when you leave your home, do not go above 78 degrees.
Even if you have an upstairs that no one ever goes in except for the kids at Christmas and Easter when they come to visit, keep it at 78 degrees because you don’t want it to start growing things in the walls and for the humidity to get out of control. Plus, if it is upstairs you need to keep it at a reasonable temperature anyway, it is going to effect the downstairs because you have that ceiling in between each. Take a look at that and again whatever is comfortable to you, the feeling is what you need to go by and not the numbers.
