Why Closing Air Vents Does Not Save Money on Energy Bills


Debunking a Common HVAC Misconception

One of the most persistent myths in home comfort management is that closing vents in unused rooms saves money on heating and cooling costs. As your trusted HVAC experts since 1953, Wighton’s is here to explain why this common practice can actually cause more harm than good.

The Science Behind Closed Vents

Your HVAC system is carefully designed to maintain a specific air pressure balance throughout your home. When you close vents, you’re creating additional pressure in the ductwork, which can lead to several problems:

1. Increased energy consumption
2. Additional strain on your HVAC system
3. Potential ductwork damage
4. Uneven heating and cooling
5. Reduced system efficiency

At Wighton’s, we’ve served the Central Coast communities, including San Luis Obispo, Santa Barbara, and Pismo Beach, for over 68 years. During this time, we’ve seen countless cases where closed vents have led to increased repair costs and higher energy bills.

Better Alternatives for Energy Savings

Instead of closing vents, consider these effective methods to reduce energy costs:
