Trying to save on energy bills without sacrificing comfort?
When summer temperatures climb, your HVAC system becomes one of the biggest energy consumers in your building. Setting your thermostat strategically can reduce costs and improve system efficiency—if you know the right temperature to aim for.
✅ Recommended Summer Thermostat Setting (per DOE)
The U.S. Department of Energy recommends setting your thermostat to:
-
78°F (26°C) when you're home
-
85°F (29°C) when you're away
This setting strikes a balance between comfort and efficiency. In fact, the DOE estimates that following these guidelines can help reduce cooling costs by up to 10% annually.
💡 Why 78°F Is the Sweet Spot
While 78°F may feel warmer than what you’re used to, you can make it feel cooler by using ceiling fans, keeping blinds closed, and limiting heat-producing appliances during the day. Plus, every degree below 78°F increases energy usage by 3–5%, which adds up quickly across multiple properties.
⚠️ Common Thermostat Mistakes
-
Setting it lower to cool faster: HVAC systems cool at the same rate no matter the temperature you select.
-
Frequent manual changes: Constantly adjusting the thermostat wastes energy and causes system wear.
-
Not programming around occupancy: Smart thermostats can automate efficiency when no one is in the building.
