These days, it seems like everything costs just a little more. As food, gas, and energy costs continue to increase, we all look for opportunities to save some money. So, we have a few suggestions that can help lower your energy costs during warm weather.
When it comes to the temperature setting of your thermostat, most people set it for comfort and forget it. That is, until it gets noticeably too cold or too warm. But is there an ideal temperature setting for your thermostat during warmer months that is both comfortable and energy efficient? Yes! The ideal temperature setting for your AC during warmer months is actually 78 degrees. However, this temperature is not necessarily set in stone because there are several variables to consider that could change this optimal AC setting. Some of these variables are:
Time of day
What activities you are performing
Humidity levels inside the house
In the article that follows, we’ll review the best AC temperature setting for each scenario and time of day. We’ll also explain how these settings can help you save money and improve the overall health of your AC unit.
Time of Day
One of the biggest factors that affects AC temperature setting is the time of day. Outside temperature in the early morning and late evening will often be cooler than in the middle of the day. During these times, you may want to adjust your thermostat up or down to correlate with the temperature outside.
Your daytime thermostat setting can be split into two different time periods: early morning and mid-morning to late afternoon.
6:00 a.m. – 12:00 a.m.
Even during warmer days, the temperatures in the morning hours from 6 a.m. to noon are not usually as hot as the afternoon to evening hours. During these times, you may want to turn the temperature of your AC up a few degrees. This helps ensure your air conditioner is not running needlessly to cool an already comfortable house.
12:00 a.m. – 6:00 p.m.
On the other hand, noon to 6 p.m. or 7 p.m. is usually the hottest time of the day. To combat these hot and often humid conditions, it may be necessary to drop your temperature setting below 78 degrees to 72-74 degrees Fahrenheit. However, if everyone in your home is still at school or working, you may want to leave the temperature set at 78 to avoid cooling an empty house.
It’s important to remember that your air conditioner also keeps the humidity out of your house. If the thermostat is set too high, it creates a damp, humid environment. Such conditions can be a problem because it can lead to the development of mold, drywall damage, or even worse, warped floors, walls, and ceilings. If you feel the humidity inside your home has increased, turn your thermostat down a few degrees to reduce the moisture level. It will help create a drier environment.
The evening hours of late summer and early fall can be a little tricky. On the one hand, it’s usually not as warm outside when the sun goes down. On the other hand, the evening hours are usually when everyone is at home and active. If this is the case, it may be necessary to keep your thermostat set at 72-74 degrees until everyone goes to bed. This can also depend on the number of people living in the house, or even whether you’re preparing a home-cooked meal. If it’s just you and your spouse, you may be fine with the temperature set at 75-77. But if you have kids and pets running around, or you’re cooking and using your oven, these things can all raise the indoor temperature noticeably. So, you might find a temperature setting in the 72-74 range more comfortable.
Your nighttime temperature setting should be like your early morning setting. However, most people prefer to set the thermostat to a lower temperature at night to create a more comfortable environment for sleeping (more on this later). If you’re an early riser and usually the first one out of bed in the morning, set the thermostat to a more comfortable daytime temperature. The good news is that a lower nighttime temperature setting will help keep your house cooler during the early and mid-morning hours.
School and/or Work from Home
If you have children who are home-schooled, or you work remotely from home, keeping your house cool and dry will be important to help maintain productivity throughout the day. Most people work better and are more productive when with a temperature setting in the 72–74-degree range. This setting is low enough to keep the house cool and dry, and keep you and the kids awake during the afternoon hours.
No One Home
One great way to lower energy costs is to avoid cooling an empty house. This is especially true during the middle of the day. If everyone in your household is either at work or school, then turning the temperature to 78-80 degrees will save you a chunk of change when the energy bill arrives. The one consideration to keep in mind is if you have four-legged friends at home. If this is the case, a temperature setting in the 76-78 range is best.
Everyone is different when it comes to creating a comfortable sleeping environment. Some people like it a little warmer, especially if you’re accustomed to sleeping with just a sheet or light blanket over you at night. However, others want to feel like they’re camping out in Antarctica overnight. Most sleep research suggests a cooler nighttime environment is better for promoting good sleep. So, if you don’t mind sleeping with a sheet or light blanket at night, you can save money, keep your AC from running at night, and still get a good night’s sleep if you keep the thermostat set between 74-76 degrees. If you can’t handle the heat, then you may need to leave the temperature set at a cooler 70-74 to create your ideal sleeping conditions.

Programmable Versus Smart Thermostats
Overall, the best way to control the temperature of your house - and save money in the process - is by utilizing either a programmable or a smart thermostat.
Programmable thermostats allow you to determine your temperature setting at different times of day without having to manually change the temperature each time. A programmable thermostat usually includes 6 or 8 different programable settings for different times of day.
The upside of a programmable thermostat is that once you set the temperature for each time of day or night, you don’t have to touch it again. Of course, you always have the option to go back and change the settings if you desire, but you won’t be required to.
Smart thermostats are all the rage now - and with good reason. These thermostats are truly smart and very good at learning and understanding your preferred temperature settings. Although these devices can be manually programmed, once they gather enough data, they can also program themselves.
A smart or learning thermostat will learn what you want the temperature to be during the different times of day and night. It will automatically adjust the temperature setting to your preferred temperature. You can also connect a smart thermostat to your Wi-Fi and control it with your phone. This is especially handy if you are on a trip and forgot to turn your air conditioner or furnace off. If you don’t already have a smart thermostat, you might want to consider getting one installed.
