The Truth About Closing Vents to Save Energy

It’s a common belief among homeowners in Dayton and beyond: if you close vents in rooms you’re not using, you’ll save money on your energy bill. While this seems logical on the surface, the truth is a bit more complicated—and surprising. At Allied Services, Inc., we often help customers understand how their HVAC systems actually work and why closing vents can do more harm than good.

Why Closing Vents Doesn’t Work the Way You Think

Your HVAC system is designed to distribute air evenly throughout your home based on a specific airflow balance. When you close vents, you’re not reducing the amount of air your system produces—you’re just disrupting where that air goes. This creates pressure imbalances in your ductwork, forcing your system to work harder to push air to the remaining open vents.

Instead of saving energy, you may be straining your system. Over time, this added pressure can lead to duct leaks, reduced efficiency, and even damage to key components like the blower motor or compressor. What’s more, you may see higher energy bills, not lower, and reduced comfort in the areas you’re still trying to keep warm or cool.

What You Can Do Instead

If you’re looking to cut costs or better control temperatures in specific rooms, there are better options than closing vents. Consider installing a zoning system or upgrading to a smart thermostat, which allows you to fine-tune temperatures by room or time of day. Regular HVAC maintenance also keeps your system running efficiently, which helps reduce utility bills across the board.
