6 Ways To Improve Air Circulation for Optimal AC Performance

During the hot summer months, walking into an air-conditioned room feels heavenly—which is why it’s so important to make sure your AC unit is in top shape.

Proper air circulation reduces energy costs and prolongs the lifespan of your unit. 

Say goodbye to the hot second level of your home—here are several strategies to improve air circulation:

1. Maintain Your AC System

  • Regular Maintenance: Schedule regular maintenance with a professional to check for any issues and ensure the system is running efficiently.
  • Clean Filters: When was the last time you replaced your filter? Clean AC filters every 1-3 months. Dirty filters restrict airflow and reduce system efficiency.
  • Inspect Ducts: Check for any leaks or blockages in your ductwork that could hinder airflow. Sealing and insulating ducts can improve circulation and efficiency.

2. Optimize Ventilation

  • Use Exhaust Fans: Turn on exhaust fans in bathrooms and kitchens to remove heat and humidity, allowing your AC to work more efficiently.
  • Open Windows Strategically: On cooler days or evenings, open windows to let fresh air in and create a cross-breeze, reducing the load on your AC.
  • Install Ventilators: Consider installing a whole-house ventilator to enhance airflow and reduce indoor air pollution.

3. Enhance Airflow with Fans

  • Ceiling Fans: Use ceiling fans to circulate the dead air in small and large rooms. In summer, set them to spin counterclockwise to push cool air down.
  • Portable Fans: Place portable fans strategically to direct cool air into occupied areas. Use box fans in windows to pull cool air in or push warm air out.
  • HVAC Fans: Keep your HVAC system’s fan set to "on" rather than "auto" to maintain constant air circulation, even when the AC isn't actively cooling.

4. Optimize Your Home Layout

  • Furniture Placement: Arrange furniture to avoid blocking vents and air returns and to ensure air can flow freely through rooms.
  • Close Doors and Vents Selectively: Close doors and vents in unused rooms to direct airflow to the areas you use most.
  • Use Air Deflectors: Install air deflectors on vents to direct airflow where it’s needed most, especially in rooms with poor circulation.

5. Improve Insulation and Sealing

  • Seal Gaps and Cracks: Check for and seal gaps around windows, doors and other openings to prevent cool air from escaping and hot air from entering.
  • Insulate Your Home: Proper insulation in walls, attics and basements helps maintain indoor temperatures and reduces the strain on your AC system.

6. Upgrade Your System

  • Modern Thermostats: Invest in a programmable or smart thermostat to optimize cooling schedules and reduce energy usage.
  • Efficient Units: If your AC system is old or inefficient, consider upgrading to a newer, energy-efficient model. Modern systems offer better performance and lower energy costs.
