Disagreements over the thermostat are common in many households. While one person feels too cold and another too warm, energy costs quietly continue to rise.
Striking the right balance may seem difficult, but there is an ideal temperature that supports both comfort and efficiency, and it’s within reach. In this article, you’ll learn what the ideal temperature is for summer and winter.
Your thermostat is the brain of your home’s heating and cooling system. It tells your furnace or air conditioner when to turn on and when to take a break. That small box on the wall has a huge impact on your daily life and your home’s energy consumption.
Think about your two biggest concerns: comfort and cost. The thermostat setting you pick directly controls both of these factors. Making small, smart adjustments to your temperature settings can lead to significant energy savings and a more comfortable home environment all year long.
Setting the correct temperature helps you avoid overworking your HVAC system. This simple action can extend the life of your equipment and prevent costly AC or heating repairs. These HVAC basics are fundamental to managing your home’s climate and expenses.
When a winter chill hits, it’s tempting to crank up the heat. You want your home to feel like a warm, cozy retreat from the cold outside. But every degree you add makes your heating system work harder, leading to higher heating bills.
The U.S. Department of Energy offers great advice for the heating season. It suggests setting your thermostat to 68 degrees Fahrenheit during the day when your family is home. This temperature keeps most people comfortable without sending their heating bills through the roof.
To save energy when you’re sleeping or away, turn the temperature down further. Lowering the thermostat seven to 10 degrees for eight hours a day can reduce your annual energy costs by up to 10%. A lower winter thermostat setting at night is also a good idea since you’re already warm under the blankets.
The script flips during our hot and humid summers. Your air conditioning seems to run nonstop just to keep the heat at bay, and a hot house is never pleasant. Setting the thermostat too low is a quick way to get an unpleasant surprise on your next power bill.
To save money and energy, the recommended thermostat setting during cooling season is 78 degrees Fahrenheit when you’re home. This might sound a little warm at first, but your body will adjust. A higher indoor temperature setting reduces the difference between inside and outside, meaning your AC runs less often and improves its energy efficiency.
To feel comfortable without changing the temperature, you can use ceiling fans to circulate air. A fan’s breeze can make a room feel several degrees cooler, helping you maintain comfort. Using window coverings to block direct sunlight can also make a huge difference.
Here are the generally recommended thermostat settings for year-long savings.
| Time of Day | Recommended Winter Temp (Fahrenheit) | Recommended Summer Temp (Fahrenheit) |
|---|---|---|
| When Home & Awake | 68 | 78 |
| When Asleep or Away | 60–64 | 82–85 |
You’ve adjusted your thermostat to the ideal temperature, but your home still feels uncomfortable. It can be frustrating when your system struggles to meet the demand. Before you call a local HVAC company, there are a few things you can check yourself.
A dirty air filter is one of the most common causes of HVAC issues. When the filter is clogged with dust and debris, it restricts airflow. This forces your system to work much harder to achieve a comfortable temperature.
Make it a habit to inspect your air filter once a month. A clean filter can improve your system’s efficiency and your home’s indoor air quality. You should plan to replace it at least every 90 days, or more often if you have pets or allergies.
Where is your thermostat located? If it’s in a bad spot, it could be getting inaccurate readings of your home’s temperature. Direct sunlight, drafty hallways, or heat from kitchen appliances can trick your thermostat.
This issue makes your system run when it doesn’t need to or shut off too early. Your thermostat should be on an interior wall away from these influences. This helps it get a true sense of your home’s overall indoor temperature.
Sometimes, the fix is as simple as turning it off and on again. Your thermostat is an electronic device, and like any other gadget, it can experience glitches. A quick reboot might be all it needs to function correctly.
Go to your circuit breaker and switch off the power to your HVAC system. Wait for a minute before you turn it back on. This simple step can often fix minor communication errors and is a good first step before contacting your local dealer for service.
Do you ever forget to adjust the thermostat when you leave home or go to bed? Programmable thermostats can take that task off your plate. You can set thermostat schedules once and let it automatically adjust the temperature based on your routine, which is great for reducing energy use.
For greater control, consider installing a smart thermostat. A smart thermostat can learn your family’s patterns and adjust settings for maximum energy efficiency. You can even control smart thermostats from your smartphone, giving you total command over your home’s comfort from anywhere.
When you’re looking at new thermostats, smart thermostats are a very energy-efficient choice. These devices are excellent at helping you achieve a comfortable indoor temperature while also lowering your energy bills. They represent a significant upgrade over older manual models.
Striking the right balance between your comfort level and energy costs doesn’t have to be a constant struggle. By using the recommended temperatures of 68 degrees Fahrenheit in winter and 78 degrees Fahrenheit in summer, you have a fantastic starting point.
Of course, every family is different, so feel free to tweak these numbers to find your ideal thermostat setting. The goal is to find what helps your family feel comfortable year-round. If you’ve tried these tips and your home still isn’t comfortable, your HVAC system might need professional attention.
A certified HVAC expert can perform a thorough inspection and answer questions about your specific heating and cooling needs. They can also ensure your system is running correctly and help you achieve a comfortable indoor environment.
