It’s a common belief: closing vents in unused rooms can save energy and lower your utility bills. But in most cases, this “trick” can actually make your HVAC system work harder and cost you more.
At Aire Serv of West Chester, we help homeowners separate HVAC myths from facts and provide practical advice for running a system efficiently and safely.
How HVAC Systems Are Designed to Work
Modern HVAC systems are built to heat and cool your home evenly. When you close vents, the system’s airflow is disrupted. This can cause:
- Increased pressure in the ductwork
- Reduced efficiency of your air conditioner or furnace
- Uneven temperatures and uncomfortable rooms
- Potential damage to ductwork and system components
Why Closing Vents Can Backfire
- Energy Savings Aren’t Guaranteed – The system works harder to push air through fewer vents, often increasing electricity use.
- Equipment Strain – Extra pressure stresses the blower motor and duct seams, which can lead to leaks or costly repairs.
- Unbalanced Comfort – Some rooms may become too hot or too cold while others remain uncomfortable.
Better Ways to Save Energy
-
Zone Your Home Properly
- A zoned system uses dampers and thermostats to control temperature in different areas without restricting airflow.
-
Use a Programmable or Smart Thermostat
- Adjust temperature schedules to reduce energy use when rooms are empty.
-
Seal and Insulate Ductwork
- Properly sealed ducts prevent air loss and improve overall system efficiency.
-
Routine HVAC Maintenance
- Clean filters, lubricate moving parts, and inspect for worn components to keep your system running efficiently.
Tips for Homeowners
- Avoid fully closing vents in central HVAC systems.
- Keep vents and registers unobstructed by furniture or rugs.
- Schedule professional duct inspections to ensure optimal airflow.
