DOE Recommended Thermostat Setting for Our Extremely Hot Arizona Summers

Many industry experts agree that a thermostat set to 75 degrees in the summer is generally considered a comfortable and energy-efficient setting. It’s a common recommendation for balancing comfort with energy savings.

However, the Department of Energy (DOE) suggests setting your thermostat to 78 degrees in extreme heat—like our Arizona summer—to provide optimal efficiency and valuable savings on the ‘wear and tear’ of the HVAC system.
