Choosing between 'Auto' or 'On' for your thermostat depends on your comfort and energy efficiency preferences. Setting your thermostat to 'Auto' means the fan only runs when the heating or cooling system is on, which is more energy-efficient and reduces wear on the fan. On the other hand, selecting 'On' keeps the fan running continuously, which can increase air circulation and filter quality in your home. However, it also uses more energy and can lead to more frequent maintenance.
FAQs & Answers
- What happens if I set my thermostat fan to 'On' instead of 'Auto'? Setting the fan to 'On' keeps it running continuously, improving air circulation and air filter efficiency but increasing energy consumption and wear on the fan.
- Is it more energy efficient to keep the thermostat fan on auto? Yes, setting the thermostat fan to 'Auto' ensures it only runs when heating or cooling is active, reducing energy use and minimizing system wear.
- Can running the fan continuously improve indoor air quality? Running the fan continuously can help circulate air and filter particles more frequently, potentially improving indoor air quality.
