Are you in a thermostat war over the ideal home temperature?

When it comes to thermostat temperature settings, people fall into one of two overarching categories: those who set the thermostat at one temperature and leave it there and those who don’t. From there, each side usually has a number of often logical and/or emotional reasons why theirs is the ideal thermostat temperature. And so, the battle of the thermostat begins. Do you engage in thermostat wars? (Flowchart) To help encourage home peace, we’re going to take a look at what some of the experts have to say about recommended thermostat settings. The information might not end the thermostat skirmishes in your home, but at least you’ll be armed with accurate information about thermostat temperature settings. Figuring out the ideal home temperature often started with trying to answer this overarching question: What temperature should my house be?

What temperature should my house be?

This answer to this question basically depends, in large part, on your seasonal needs. What works in the summer needs tweaking for a climate where winter brings serious snow and cold weather. Energy authorities offer recommended thermostat settings based on the seasons.

Ideal thermostat temperatureFor summer, the ideal thermostat temperature is 78 degrees Fahrenheit. Energy.gov suggests setting the air conditioning thermostat to 78 when you are home and raising it or turning it off entirely when you are away. Why cool an empty house? Programmable thermostats can help make this monitoring easy and human error-free. Program them once and walk away! The thermostat can be set to start cooling your home shortly before you arrive so it’s the ideal home temperature when you walk in the door. Whatever temperature you and your partner decide is the ideal home temperature, do not try to cool your home faster by setting your thermostat at a colder setting than normal when you turn on your air conditioner. Energy.gov says this strategy does not, in fact, cool a home any faster and ultimately can lower the temperature too much and therefore create an unnecessary expense.

For winter, experts say the ideal thermostat temperature is 68 degrees Fahrenheit when you’re at home. Energy.gov suggests setting the thermostat at home while you’re awake and lowering it while you’re asleep or away. Lowering your thermostat 10-15 degrees for eight hours can reduce your heating bill by 5-15%. That’s a potential savings of as much as 1% for each degree if the period of the setback is at least eight hours. The Consumer Energy Center says that for each degree you lower your heat in the 60- to 70-degree range, you can save up to 5% on heating costs. In addition to echoing Energy.gov’s 68 degrees as the ideal thermostat setting, the non-profit suggests layering clothing as a way to stay warm in the cooler house temperature.

What is the recommended temperature setting for sleeping?

One added benefit of maintaining the ideal home temperature? You might sleep better. When you sleep, the set point for your body temperature drops, WebMD says. If it’s too cold or too hot, it throws off your internal temperature, which in turn can make your sleep more fitful. The ideal home temperature for sleeping is generally between 65 and 72 degrees Fahrenheit, with this caveat: Everyone’s body temperature is different and therefore what he or she requires for comfort during the day might change at night. If you live with someone who loves to sleep in Arctic-like temperatures or someone who likes to feel as if she is in the Tropics, well, that’s one thermostat debate we can’t help you win.

If setting your thermostat on 78 in the summer will that make your house even hotter

    Hi Diane- Thanks for your comment! Setting your thermostat at 78 in the summer (assuming that you have central AC) should make your house cooler and maintain energy efficiency. If you rely on window units or fans, you’d need to take a different approach though.
