What AC Temperature is Best for the Summer?

During the summer months, finding the right air conditioner temperature to set your thermostat can be a delicate balance between maintaining comfort and keeping energy costs in check. The U.S. Department of Energy recommends setting your thermostat to 78°F (26°C) when you are at home and awake. This temperature is generally considered to strike a good balance between comfort and energy efficiency.

However, individual preferences and tolerance to heat may vary, so it’s essential to find a temperature that works best for you and your household. If 78°F feels too warm, try gradually increasing the temperature from your preferred setting by one or two degrees until you find a comfortable compromise.

When you’re away from home or asleep, consider raising the thermostat by 7-10°F for at least eight hours a day. This can help you save up to 10% on your cooling costs without sacrificing comfort when you’re at home and awake.

Don’t Go Too Low!

Setting your thermostat too low in the summer can actually increase your energy bills because your air conditioning system has to work harder and run longer to maintain the lower temperature. This increased workload not only consumes more energy, but it also puts additional strain on your AC unit, potentially leading to more frequent repairs and a shorter lifespan for the system.

Furthermore, maintaining a lower indoor temperature can cause a greater temperature difference between the inside and outside of your home, resulting in faster heat transfer and making it harder for your air conditioner to keep up with the cooling demand.

By setting your thermostat at a higher temperature, you can reduce energy consumption and save money on your utility bills. This is the best AC temperature for homes that are looking to save on energy costs, while maintaining a comfortable indoor environment.

More Ways to Stay Cool

Air Conditioner Maintenance

It’s also essential to ensure that your central air conditioning system is running efficiently during the summer months. Just like any other appliance, air conditioners need maintenance to perform at their best. Changing the filters every month and scheduling regular professional tune ups can help keep your air conditioner running smoothly and ensure that it can handle the summer heat.


Another way to stay cool during the summer months and reduce the strain on your AC system is to use natural ventilation. This can be achieved by opening windows and doors, using ceiling fans, or even taking advantage of outdoor spaces during the cooler parts of the day. These practices help create a natural breeze that boosts air circulation in your home, helping you stay cool without relying solely on your air conditioner.


Insulation is also crucial in maintaining a comfortable indoor temperature during the summer. Poor insulation means that your home will be warm in the daytime and cold at night. Make sure that your home is adequately insulated to help regulate temperature and reduce strain on your AC system.
