Why Setting Your Thermostat Higher Doesnt Save Money When Youre Away

Common HVAC Myths That Cost You Money

One of the most persistent myths in home comfort is that cranking up your thermostat to a much higher temperature when you leave for work will save you money. As your trusted heating and cooling experts in Naperville, we’re here to explain why this common belief actually costs you more in the long run.

The Science Behind the Myth

Many homeowners believe that setting their thermostat 10-15 degrees higher when leaving for the day reduces energy consumption. However, this practice forces your HVAC system to work harder when you return home, potentially negating any savings you might have achieved.

Here’s what really happens:

  • Your home heats up significantly during your absence
  • Furniture and walls absorb excess heat
  • Your AC must run longer to remove both air temperature AND stored heat
  • System stress increases, potentially leading to premature wear

The Smart Solution

Instead of dramatic temperature swings, we recommend:

  • Installing a programmable thermostat
  • Setting temperature increases of only 3-4 degrees when away
  • Maintaining consistent humidity levels
  • Scheduling regular maintenance checks

By following these guidelines, Naperville homeowners can achieve genuine energy savings while protecting their HVAC investment. Remember, gentle adjustments are always more efficient than extreme temperature changes.

For optimal performance and real energy savings, consider scheduling a professional evaluation of your system. Small adjustments to your daily routine can lead to significant improvements in both comfort and efficiency.
