How to set your thermostat for maximum comfort and lowest summer electric bill.
The Department of Energy recommends 78°F when you’re home and 85°F or off when you’re away. That’s the energy-saving target.
In practice, most Texans live closer to 72–75°F. Every degree lower costs about 3% more on cooling.
A smart thermostat that learns your schedule (Nest, Ecobee, Honeywell) typically saves 10–15% on cooling costs and pays for itself in a year or two.
Use ceiling fans! A fan running counter-clockwise lets you set the thermostat 3–4 degrees higher with the same comfort.
