The Truth About Closing Air Vents to Save Energy in Unused Rooms


A Common Energy-Saving Misconception

As a trusted HVAC service provider since 1953, Wighton’s has encountered numerous energy-saving myths throughout our decades of service to the Central Coast community. One of the most persistent misconceptions we hear from our San Luis Obispo County customers is that closing air vents in unused rooms will help reduce energy bills.

Why This Myth Needs Debunking

Many homeowners believe that by closing vents in empty rooms, they’re being energy-efficient and saving money on heating costs. However, this practice can actually lead to several problems:

1. Increased System Pressure
– Closing vents creates additional pressure in your ductwork
– This forces your HVAC system to work harder
– Can lead to increased energy consumption

2. Potential System Damage
– Extra pressure can cause duct leaks
– May lead to premature system failure
– Could void equipment warranties

3. Reduced Comfort
– Disrupts intended airflow patterns
– Creates uneven heating and cooling
– May cause temperature inconsistencies throughout your home

The Professional Solution

At Wighton’s, we recommend maintaining all vents open as designed. If you’re concerned about energy efficiency, consider these alternatives:

– Schedule regular maintenance checks
– Install a smart thermostat
– Improve your home’s insulation
– Use zoned heating and cooling systems
