多位专家指出，将恒温器调高几度是在保证舒适度同时实现能源效率最大化的理想策略 [1]。美国能源部数据显示，每天在离家期间调整温度设定值 7-10 华氏度（约 4-6 摄氏度）持续 8 小时，可节省高达 10% 的年度冷暖费用 [1]。Patrick Phelan 补充称，仅将调高恒温器 1 华氏度（约 0.6 摄氏度），即可节约大约 3% 的制冷成本 [1]。
关于空调的使用时长，Elizabeth Hewitt 表示，离开家仅仅 15 分钟就关闭空调并不能带来节能收益；相比之下，在工作日离家约 8 小时的情况下通常能节省更多能源和金钱 [1]。此外，智能恒温器也能帮助用户实现大约 10% 的节能效果 [1]。不过专家也提醒，在潮湿地区长期关闭空调可能会导致霉菌滋生问题 [1]。
Experts state that adjusting a thermostat by several degrees represents an optimal balance between energy efficiency and comfort [1]. According to data from the U.S. Department of Energy, turning off cooling systems or raising the temperature setting by 7 to 10 Fahrenheit (4 to 6 Celsius) for eight hours each day can save up to 10 percent on annual heating and cooling costs [1]. Patrick Phelan notes that increasing the thermostat setting by just one degree Fahrenheit saves approximately three percent in air conditioning expenses [1]. However, Elizabeth Hewitt warns that leaving a home uncooled for merely 15 minutes yields no energy savings; instead, saving more money typically requires closing off usage during workday hours when people are away [1]. While turning up the thermostat is effective, experts caution against long-term shutdowns in humid regions as this can lead to mold growth issues [1]. Additionally, installing a smart thermostat offers another avenue for efficiency, potentially delivering about 10 percent energy savings [1].
