It’s over 100 degrees every day. What temperature should I leave my AC at?
Updated: Jul 25, 2024
On these 100 degrees + days, a good temperature setting is 75 to 78 degrees depending on your comfort level.
If your system is sized properly for your home, it is designed to achieve a 30-degree temperature difference at 105 outside temperature. For example, 105 degrees outside, 75 degrees inside. As the outside temperature exceeds 105, your inside temperature increases accordingly, for example, 110 degrees outside, 80 degrees inside and so on. Although your system may bring the inside temperature down lower than this, it is not recommended as it could be a health risk.
So, if it is 110 degrees outside and your A/C system will only go down to 80 degrees, don’t panic, it is doing its job and you should still be comfortable.
This is such a helpful breakdown for managing home temperatures during extreme heatwaves! People often panic when their thermostat doesn't hit freezing temperatures on a 100+ degree day, not realizing the limitations of a standard 30-degree temperature differential. Understanding how system capacity works really helps prevent unnecessary service calls. For anyone wanting to verify their property's overall environmental health or check for hidden allergens during the peak summer months, getting professional indoor air quality testing is a really smart step
When searching for HVAC Installation Services in Pittsburgh, it’s important to find a company with experience in the region's specific climate challenges. A skilled technician will understand the need for a heating system that can handle freezing temperatures and a cooling system that can tackle the summer heat. This ensures that your HVAC system performs efficiently and lasts longer.
Setting your air conditioning between 75 and 78 degrees on extremely hot days keeps your home comfortable without overworking your system. Properly sized AC units handle temperature efficiently, ensuring safety and energy savings while maintaining a cool indoor environment.
