Keep Your Home Comfortable & Utility Bills Low: The Best Temperature to Set a Home Thermostat

In 2023, more and more homes are becoming equipped with central heating and cooling systems. With a simple-to-use thermostat, these systems allow the homeowner to set and maintain a preferred, consistent temperature throughout their home. There is a lot of debate surrounding the best temperature to set a home thermostat to ensure comfort and energy efficiency. In this blog, we will discuss the optimal thermostat setting and the factors that affect this.

Central Heating & Cooling Systems Allow Homeowners to Choose the Right Temperature

Before central heating and cooling systems, homeowners had to use stand-alone heaters or window AC units. These appliances often prove challenging to control and maintain a consistent temperature. With central heating & cooling systems, you can easily set your thermostat to the specific temperature you want rather than relying on individual devices.

What is the Best Temperature to Set a Home Thermostat to in the Winter?

The weather can get very cold in the winter, especially in Massachusetts. When you are inside your home, you want to ensure you stay warm and comfortable, but increasing the heat can also increase your utility bills. According to the U.S. Department of Energy, the ideal temperature to set your thermostat to in the winter is 68°F (20°C) when you are at home.

What Should You Set Your Thermostat to During the Summer?


During the summer, Massachusetts can get quite hot and humid. Air conditioning is a must to keep your home comfortable and free from humidity. However, running the AC can raise your utility bills, similar to increasing the heat. In the Summer, according to the U.S. Department of Energy, it is recommended to set your thermostat to 78°F (26°C) when you are at home.

Although these temperatures are the optimal settings for when you are active and inside of your home, adjusting your thermostat when sleeping or away from home for extended periods can save even more money on your utility bills. According to the U.S. Department of Energy, lowering your thermostat by 10-15 degrees in the Winter or increasing it by 5-10 degrees in the Summer for eight hours at a time can save up to 10% on heating and cooling costs.

Optimizing Temperature Settings for Energy Efficiency

While these temperatures may be ideal for comfort, they might not always be feasible if you want to keep your utility bills low. Here are some tips for optimizing your temperature settings while reducing energy consumption:

  • Use an automatic or programmable thermostat to maintain a consistent temperature rather than constantly adjusting the thermostat.
  • Consider using ceiling fans and space heaters for specific rooms to reduce the overall energy consumption of your central heating and cooling system.
  • Invest in proper insulation and sealing to keep the cool or warm air inside, allowing you to set the thermostat slightly lower or higher without compromising comfort.

I live in Arlington MA. and called Mass Save for a free energy audit and they sent an auditor from Absolute Energy Solutions. I spoke with Kelly on the phone a few times and we worked out a plan and a day for them to come. Kelly was very friendly, personable and helpful on several occasion and she is obviously a great asset to the company. A couple weeks later, three hard working gentlemen came and did a great job adding insulation to the attic and a large crawl space and to the basement in a few areas that needed attending to. They also added weather stripping to all exterior doors to remove any drafts. All of this work was 100% free to me because of my lower income status and it will save me a lot of energy use and money. After a lot of very hard work that took the three men most of the day they cleaned up very well and left. Very friendly and professional!

We participated in the Mass. Energy Saving Program in December 2022. Eric and Mario came to our house and gave us some valuable suggestions and offered us very good quotes if we decided to have some home improvements in our attic to save our house energy cost in the future. Eric always answered our questions promptly and in detail by emails. Mario and his team came to add another 9" insulation in our attic. They were all professional, friendly, and responsive for what they did during their long working day. They cleaned the areas after their work. We were very happy with their work. We would like to recommend the company to any friends and relatives if they need to have some energy saving projects.
