What’s the Best Temperature for Your Home?

Now that spring is here, chances are you’re getting ready to switch from running the heat to running the air conditioning. Do you know the best temperature for your home?

Here in Atlanta, the open window weather period is pretty short. We’ll probably be sweltering within a month or so. After the long winter, I always forget what temperature is ideal for the air conditioning. According to the Department of Energy, 78 F is the ideal temperature for your thermostat. That temperature is a little warm for some folks, but from a health perspective it’s safe for everyone.

When I was looking for information on the best temperature for your home, I stumbled across the infographic below, which I hadn’t seen before. It considers more than just comfort, looking at things like your flooring, furniture, who is in the house, and what you’re doing. It also lists some of the common heat producers, which may be battling your A/C as it struggles to maintain the best temperature for your home.

Check out the graphic and the list below it with some things that stood out for me. I’d love to hear your thoughts on this infographic, too!

What is the best temperature for your home?

It’s actually looking like that good old 78 F is within or close to most of the ranges on this graphic. Here are a few things that seemed worth noting:

  • Sleeping – They recommend 68 F. If you have a programmable thermostat, you can try having it dip down that low just during the wee hours. Since it’s cooler outside late at night, your A/C shouldn’t have to kick on as much to maintain that temperature as it would in the early evening.
  • The Elderly – It looks like 75 F is the max temperature for older folks, though they don’t define an age for “elderly.” Maybe you can experiment and see what temperature works for you?
  • Tasks – The tasks section seemed a little bit strange. The best temperature for sleep made sense, but surely they’re not saying that you should set the thermostat to 170 F when you’re making tea.
  • Temperature Settings – The part that I found the most helpful was the Temperature Settings list for a programmable thermostat. We finally have one, and I have been trying to decide how to program it for the summer. This looks like a good jumping-off point!

I’d love to hear from you guys! How do you balance comfort and conservation in the summer?

I like between 76 and 78 F.

It's been 95º for the past week or so in Indiana. And, of course our air conditioner went out the other day! After the repairman left, it ran for 9 hours straight to get it back to 78º again! I guess our electric bill will be outrageous this month!

We keep the house at 21-22 C. which seems to be warm enough. We don't have AC so a window fan works just fine.

Makes sense that different things (and people and animals) are optimized at different temperatures. Thanks.

i run hot for sure. i just can't sleep without a fan pointed at me. i'm not a fan of AC, but i must use it in the southern summer. i guess what i save in heating in winter goes to that.

They say 25degs C but that's way too hot for me. I love winter - feel alive when my nose is frozen.
