How To Improve Airflow And Boost Air Quality In Your Ducted HVAC System

Heating, ventilation, and air conditioning systems control the temperature, humidity, and airflow in a building. Heating and air conditioners regulate temperature and airflow, while ventilation systems improve air quality by removing stale air in the home. If you are experiencing air quality issues in your home, you need to assess the performance of your HVAC system. Below are four tips to help you improve airflow and boost the quality of indoor air. 

Rethink Your Zoning Design

Ducted HVAC systems are divided into zones to ensure efficient heating and cooling. The temperature and airflow in each zone are controlled independently using individual thermostats, dampers, and vents. When zoning your system, you need to consider the following crucial factors: 

  • The size of the space
  • Number of windows
  • Solar orientation
  • Distance from the furnace or central air conditioner
  • Quality of insulation 

If your system isn't zoned correctly, there will be weak airflow, hot spots, and cold spots throughout the home. Thus, if you are experiencing airflow issues, assess and redesign your HVAC zones. 

Keep the Ducts Clean and In Good Condition

Ducts distribute heated or conditioned air throughout the home. Worn or leaky ducts can lose air to the surroundings, causing weak airflow and insufficient heating and cooling. Dirty ducts transfer dust, pollen, mold, and other pollutants into the air, lowering the quality of indoor air. 

Regularly inspect your ducts for leaks and wear and tear. Repair the damaged or leaking ducts to resolve airflow issues and increase the efficiency of your heating and cooling systems. Also, clean the ducts annually to remove pollutants from the system and improve the air quality in your home.

Invest in High-Quality Air Filters

Dust, debris, pollen, and other indoor pollutants originate from open doors and windows, clothing, remodeling projects, and pets. These substances can pollute indoor air and cause allergies in a household. The best way to control them is by investing in high-quality air filters for your HVAC system. High-quality filters purify the air by trapping microscopic particles, such as dust, smoke, and mold spores. Clean the filters every few months to remove the trapped debris and improve airflow throughout your home.

Invest in Whole-House Ventilation Systems 

Ventilation systems improve indoor air quality by bringing fresh air into the home. They also remove excess humidity and prevent mold growth on indoor surfaces. If your home doesn't have sophisticated heat recovery ventilators, you can install whole-house ceiling fans. Ceiling fans draw fresh air through open windows and doors and exhaust stale air to the outside. In the summer, ceiling fans can remove excess heat from the building, lowering the cooling load on your air conditioner.
