when should you turn your heat on

The best time to turn on your heat in the fall is generally when indoor temperatures start to drop below 64°F (about 18°C). This aligns with health experts' advice, including the World Health Organization, which recommends keeping indoor air temperatures between 64°F and 75°F for comfort and health. If there are vulnerable people like seniors or young children, turning on the heat a bit earlier is advisable. Some guidelines suggest watching outdoor temperatures too—when daytime temperatures consistently hover around 60-65°F and evening temperatures regularly fall below 55°F, it's a good time to switch from air conditioning to heating. Others say once outdoor temperatures drop below 50-60°F, it's practical to consider turning on the heat depending on how comfortable the indoor environment feels. Many experts also recommend turning heat on around mid-October, coinciding with the end of daylight saving time and consistent temperature drops. Overall, the decision should be based on indoor comfort—if the air inside feels chilly and falls below about 64°F, it's time to turn the heat on to maintain a warm and healthy environment.
