Debunking the Myth: Closing Vents Saves Energy on AC Bills

The Truth About Closing Vents in Unused Rooms

A common misconception among homeowners is that closing air vents in unused rooms will save energy and reduce air conditioning costs. All Climate Heating & Air Conditioning is here to debunk this myth and explain why this practice may actually be counterproductive.

The Myth

Many people believe that by closing vents in rooms they’re not using, they can redirect cool air to other areas of the house and save money on their energy bills. This misconception has been circulating for years, leading homeowners to inadvertently cause problems with their HVAC systems.

The Reality

Closing vents can actually:

  • Increase pressure in your ductwork
  • Cause your AC system to work harder
  • Lead to potential system damage
  • Reduce overall energy efficiency

Why Closing Vents is Problematic

Your HVAC system is designed to cool a specific square footage. When you close vents, you’re not changing the amount of air your system produces. Instead, you’re creating an imbalance that can lead to:

1. Increased duct leakage
2. Frozen evaporator coils
3. Cracked heat exchangers

The Better Alternative

Rather than closing vents, consider these energy-saving tips:

  • Use a programmable thermostat
  • Ensure proper insulation
  • Schedule regular AC maintenance
