Should Your Thermostat Be Set to Auto or On for Better Efficiency?

Learn why setting your thermostat to 'auto' is more energy-efficient and better for your HVAC system than keeping it 'on' continuously.

76 views

Setting your thermostat to 'auto' is generally more energy-efficient because it allows the fan to run only when the heating or cooling system is active. Using the 'on' setting keeps the fan running continuously, which can increase your energy bill. The 'auto' setting also aids in better humidity control and reduces wear and tear on the system, prolonging its life.

FAQs & Answers

  1. What does the 'auto' setting on a thermostat do? The 'auto' setting runs the fan only when the heating or cooling system is actively working, helping save energy and reduce system wear.
  2. Is it cheaper to keep the thermostat fan on 'auto' or 'on'? Keeping the thermostat fan on 'auto' is generally cheaper because the fan only runs when necessary, reducing electricity use compared to running continuously.
  3. How does thermostat fan setting affect humidity control? Using the 'auto' setting helps maintain better humidity control by only circulating air when heating or cooling is active, preventing excess moisture buildup.
