The Truth About Closing Air Vents in Unused Rooms

At CBM Heating & Air, LLC, we often encounter homeowners who believe that closing vents in unused rooms will save energy and reduce their cooling costs. Today, we’re here to debunk this common misconception 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 air to other areas of the house and save money on their energy bills. This seems logical at first glance, but it’s not how modern HVAC systems are designed to work.

The Reality

Closing vents can actually lead to several problems:

• Increased pressure in the ductwork
• Reduced efficiency of your air conditioner
• Potential damage to your HVAC system
• Uneven cooling throughout your home

Why Closing Vents is Counterproductive

Your air conditioning system is designed to cool a specific square footage. When you close vents, you’re creating an imbalance in the system. The air that would have flowed into the closed-off room now has nowhere to go, increasing pressure in the ducts and forcing your AC to work harder.

This extra strain can lead to increased energy consumption and potentially shorten the lifespan of your system. In some cases, it may even cause your air conditioner to freeze up, requiring professional repair.

The Better Alternative

Instead of closing vents, consider these energy-saving tips:

• Use a programmable thermostat
• Ensure proper insulation throughout your home
• Schedule regular maintenance for your HVAC system
• Use ceiling fans to enhance air circulation
