Debunking the Myth: Closing Vents Saves Energy

The Truth About Closing Vents in Unused Rooms

As a trusted HVAC service provider in the Chicago area, we at Chicago HVAC Repair Doctor often encounter misconceptions about energy-saving practices. One common myth we’d like to address today is the belief that closing vents in unused rooms saves energy and reduces heating or cooling costs.

Why Closing Vents Doesn’t Work

Many homeowners think that by closing vents in unoccupied rooms, they’re redirecting air to other areas of the house and saving energy. However, this practice can actually lead to several problems:

  • Increased pressure in the ductwork
  • Reduced efficiency of your HVAC system
  • Potential damage to the air handler or heat exchanger
  • Uneven heating and cooling throughout your home

The Science Behind It

Your HVAC system is designed to distribute air evenly throughout your home. When you close vents, you’re creating an imbalance in the system. The air that would have gone to those rooms is now trapped in the ductwork, increasing pressure and forcing your system to work harder.

What You Should Do Instead

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

  1. Invest in a programmable thermostat
  2. Ensure proper insulation throughout your home
  3. Schedule regular maintenance for your HVAC system
  4. Use ceiling fans to improve air circulation
