When it comes to saving energy, upgrades like installing double-pane windows, switching to high-efficiency appliances, or adding extra insulation in the attic can take a big bite out of the utility bill. But it’s not always necessary to make a big change to see a big difference. Minor adjustments to behaviors and habits can have incremental benefits that add up. Unfortunately, there are several misleading “tips” for saving energy that actually do the opposite. Closing off rooms to improve efficiency is a persistent myth that can end up increasing energy bills.
The oft-repeated tip states that a home’s HVAC system continuously cools all of the air inside of the structure. Closing the doors of rooms that aren’t in use reduces the overall volume of air that the HVAC system needs to keep cool, meaning it doesn’t have to work as hard. This theory has some logic to it but overlooks critical information on how HVAC systems work.
What actually happens is that the air in the room that’s closed gets trapped, which blocks airflow. That air won’t stay blocked for long. It will find ways to escape through cracks in doorframes, floorboards, windows, and anywhere else it can seep out. That means conditioned air is being pushed outdoors, where it’s wasted, rather than being allowed to circulate and cool the whole house. It’s better to keep doors open or install a transfer grill to allow airflow throughout the home.
