A lot of customers I help have vent confusion. They believe closing vents in rooms they're not using is best, thinking unused vents are like leaky faucets, pouring precious cool air into the void.

But here's the twist: closing vents can backfire, causing more harm than good for your system.

Closing vents won't save energy

In fact, closing vents can disrupt the balance of your modern central air conditioning system, which is designed to distribute air evenly throughout the entire home. This can lead to increased pressure in the ducts and potential system inefficiencies.

Instead:

• Keep all vents open to maintain the system's designed airflow. This ensures air conditioner efficiency and desired comfort level without strain on your system.
• Upgrade your A/C if it's over 10 years old for 20-40% savings. Choose a high-efficiency, appropriately sized model with high SEER2 15.2 rating and ENERGY STAR^® qualification. Use one of our qualified contractors on your project and receive an instant $200 rebate.

Three tips to boost your A/C efficiency:

1.    Seal air leaks:

• Check window seals each season.
• Caulk cracks.
• Replace weather strips on doors.

2.    Control heat intake:

• Install window coverings. 
• Set a comfortable thermostat temperature.
• Use a programmable or smart thermostat to avoid unnecessary cooling.

3.    Maintenance:

• Schedule regular check-ups.
• Replace filters monthly.
• Perform annual coil inspections.

Bottom line:

Keeping A/C vents open is key to maintaining the system and ensuring energy efficiency. Get more savings tips and personalized energy insights with our free Energy Manager.
