The Truth About Closing Air Vents in Unused Rooms

At Absolute Mechanical Systems, we often hear homeowners say they close vents in unused rooms to save energy and reduce their heating or cooling costs. This common misconception has been circulating for years, but it’s time to set the record straight.

The Myth

Many people believe that closing vents in unoccupied rooms will redirect airflow to other areas of the house, thereby improving efficiency and reducing energy consumption. Unfortunately, this popular belief is not only incorrect but can actually lead to several problems.

The Reality

Closing vents in your home can:

• Increase pressure in your ductwork
• Strain your HVAC system
• Reduce overall system efficiency
• Lead to potential air leaks in your ducts
• Create imbalanced temperatures throughout your home

Modern HVAC systems are designed to distribute air evenly throughout your entire house. When you close vents, you disrupt this balance, forcing your system to work harder and potentially causing damage over time.

The Solution

Instead of closing vents, consider these energy-saving alternatives:

1. Schedule regular maintenance for your air conditioner and furnace
2. Upgrade to a programmable or smart thermostat
3. Improve your home’s insulation
4. Seal air leaks around windows and doors
