Demystifying the Myth of Closing Vents for Energy Savings


When it comes to home cooling and energy efficiency, there are numerous myths and misconceptions floating around. One persistent myth is that closing vents in unused rooms can save energy and money on your utility bills. In this blog post, we’ll explore the truth behind this belief and provide insights from our experts at Conway Air Conditioning.

The Myth Debunked

Contrary to popular belief, closing vents in unused rooms does not necessarily lead to energy savings. In fact, it can have the opposite effect and potentially cause more harm than good to your air conditioning system.

Increased Strain on the System

  • Closing vents increases the overall air pressure within the ductwork, causing your AC system to work harder to distribute the cooled air.
  • This added strain leads to higher energy consumption and can potentially shorten the lifespan of your system.

Uneven Cooling and Comfort Issues

  • By closing vents, you disrupt the carefully designed airflow balance within your home.
  • This can result in uneven cooling, with some rooms becoming too cold while others remain uncomfortably warm.

The Better Approach

Instead of closing vents, our experts at Conway Air Conditioning recommend the following strategies for improving energy efficiency:

  1. Proper air conditioning maintenance and regular tune-ups to ensure your system is operating at peak performance.
  2. Upgrading to a more energy-efficient HVAC system if your current one is outdated or inefficient.
  3. Improving insulation and air sealing in your home to prevent cooled air from escaping.
  4. Installing a programmable thermostat to better regulate temperatures and avoid unnecessary cooling when rooms are unoccupied.


While the myth of closing vents for energy savings may seem logical at first glance, the reality is quite different. By understanding the potential drawbacks and exploring more effective approaches, you can ensure optimal comfort, efficiency, and longevity for your air conditioning system.
