Do You Have an Indoor Air Quality Problem?

Did you know there could be many contaminants floating around your home right now? The air inside your home can be 2-5 times more polluted than outdoor air, according to the Environment Protection Agency.

A sure sign of poor air quality is visible dust and dirt located near ducts. Some people may experience various health conditions, such as cold or flu symptoms, because of poor air quality. The Environmental Protection Agency lists Indoor Air Quality among the top 5 risks to human health. Your system needs immediate inspection and maintenance if the air quality is resulting in health issues.

An inspection of your system's filtration, humidity regulation and ventilation processes will help identify any factors contributing to poor air quality. A number of airborne particles are likely flowing throughout your home if your equipment isn't properly maintained. Most of these particles are invisible to the eye and can include the following:

  • pollen and spores
  • human skin flakes
  • candle soot
  • infiltrating dust
  • viruses
  • bacteria
  • fungi
  • pet dander
  • tobacco or wood smoke
  • cooking smoke and airborne grease
  • radon gas
  • chemical fumes
  • volatile organic compounds

How Can You Improve Your Indoor Air Quality?

High Quality Air Filters Make a Difference

Air conditioning filtration efficiency depends on the type of air cleaner used, and the type, number and size of the particles in the air stream. Filters may capture as little as 3% of air contaminants for ordinary throwaway fiberglass filters, or up to 99.9% for HEPA (High-Efficiency Particulate Air) filters.

Upgrading to a HEPA Filter will help keep your air cleaner and more breathable for longer periods of time. Additionally, monitoring and replacing your air filters regularly will reduce the amount of dirt and dust build-up in your ducts, keeping them cleaner and reducing maintenance costs in the long run.

Control the Humidity of Your Home

Humidity control is vital when improving air quality. Too much humidity can leave your home feeling damp and sticky. Excess moisture in a home can lead to mold and mildew, causing health issues for its occupants. On the other end of the spectrum, humidity levels that are too low can leave you with dry skin and burning eyes and can possibly damage furniture, wood floors and valuable artwork. Adding a humidifier and dehumidifier to your HVAC system will help regulate humidity levels throughout the home.

Good Ventilation Allows Clean Air To Flow

Most people believe the key to keeping a contaminant-free home is to limit outside airflow. This is not a good practice for maintaining healthy indoor air quality. If a home is sealed too tight, contaminates are trapped in the home and have nowhere to escape. Outside air needs to be exchanged with inside air in order to create a comfortable and healthy living environment.

Ventilators may be applied to new installations or retrofit systems in order to accomplish the much needed air exchanges. With ERV (Energy Recovery Ventilators) and HRV (Heat Recovery Ventilators) connected to your current HVAC system, fresh air is brought in and distributed throughout your home to dilute emissions from indoor sources.
