Debunking the Myth: Closing Vents Saves Energy on Air Conditioning

The Truth About Closing Vents in Unused Rooms

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

Why Closing Vents Doesn’t Work

Many people believe that by closing vents in unoccupied rooms, they’re redirecting cool air to other areas of the house and reducing the workload on their air conditioner. However, this practice can lead to several issues:

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

The Science Behind It

Your HVAC system is designed to cool a specific square footage, and closing vents doesn’t change that. Instead, it creates an imbalance in the system, forcing it to work harder and potentially leading to increased energy consumption.

What You Should Do Instead

Rather than closing vents, consider these energy-saving alternatives:

1. Schedule regular maintenance with Murphy’s to ensure optimal system performance
2. Use a programmable thermostat to adjust temperatures when you’re away or sleeping
3. Improve your home’s insulation to prevent cool air from escaping
