Debunking the Myth: Closing Vents Saves Energy on Air Conditioning

The Truth About Closing Vents in Unused Rooms

At High Quality Heating and Air, we often hear homeowners ask about ways to save energy and reduce their cooling costs. One common misconception we encounter is the belief that closing vents in unused rooms will save energy and lower utility bills. Today, we’re here to debunk this myth and explain why it’s actually counterproductive.

The Myth:

Many people think that by closing vents in rooms they’re not using, they can redirect cool air to other areas of the house and reduce the workload on their air conditioner. This seems logical at first glance, but it’s not how modern HVAC systems are designed to function.

The Reality:

Closing vents can actually lead to several issues:

• Increased pressure in the ductwork
• Reduced efficiency of the air conditioning system
• Potential damage to the AC unit
• Uneven cooling throughout the house

Why Closing Vents Doesn’t Work:

Modern air conditioners are designed to cool a specific square footage. When you close vents, you’re not reducing the amount of air the system produces; instead, you’re creating pressure imbalances. This can force air into unintended spaces, like attics or crawl spaces, leading to energy waste and potential moisture problems.

What You Should Do Instead:

To maximize efficiency and save on cooling costs:

1. Keep all vents open and unobstructed
2. Ensure proper insulation throughout your home
3. Use programmable thermostats to adjust temperatures when you’re away
4. Schedule regular AC maintenance with professionals
