Picture of a woman on her sofa holding a remote and pointing it at the AC.

Knowing the ideal AC temperature in summer is not only about comfort but also about efficiency. The recommended temperature is 78°F (25°C) during the summer days. At night, when you go to sleep, it can be a little higher.

Finding the optimal temperature setting for your AC during these hotter months balances comfort and energy efficiency. So, what is the best AC temperature in summer? Read on and discover all about it.

What Temperature To Set The AC In Summer?

The best temperature for AC in summer is 78°F (25°C) when you are at home and awake. It is considered the most efficient temperature for AC in summer because it balances comfort and energy savings. This way, you can also save on air conditioning costs.

If you are away from home or sleeping, raising the thermostat by 7-10°F (about 3-5°C) can reduce your energy consumption without compromising your comfort too much.

Why Is My AC Not Cooling?

Even with the thermostat set to the ideal temperature, you might find that your AC is not cooling your home effectively. Here are some common reasons why this might be happening:

  1. Dirty Air Filters: Clogged filters restrict airflow, making it harder for your AC to cool your home. Regularly replacing or cleaning your filters can significantly improve performance.

  2. Refrigerant Issues: Low refrigerant levels can hinder the cooling ability. It could be due to a leak or improper refrigerant charge. A professional technician can diagnose and fix this issue.

  3. Blocked Condenser Unit: Debris, like leaves, dirt, and grass, can obstruct the outdoor condenser unit. Ensuring it is clean and unobstructed allows for better heat exchange and cooling.

  4. Thermostat Problems: If your AC thermostat is not working correctly, it may not communicate properly with your AC unit. Check the thermostat settings, and if necessary, replace the batteries or the thermostat itself.

  5. Leaky Ducts: If your ductwork leaks or has holes, cool air can escape before it reaches your living spaces. AC duct maintenance and sealing leaks can improve your AC's efficiency and cooling ability.

  6. Old AC Unit: Sometimes, the problem might be that your AC unit needs to be updated or the right size for your home. In this case, upgrading to a new, energy-efficient model might be the best solution.
