Understanding Indoor Air Pollutants

Various sources can contribute to indoor air pollution, including:

  • Combustion Sources: Gases or particles emitted by heating systems, fireplaces and tobacco products can adversely affect indoor air quality.
  • Building Materials: Household materials, such as asbestos, lead and volatile organic compounds (VOCs), can release pollutants into the indoor environment.
  • Outdoor Sources: Outdoor air pollutants, such as pollen, mould and industrial emissions, can enter your home through windows, doors and ventilation systems.
  • Indoor Humidity: High humidity levels can promote mould and mildew growth, while low humidity can cause dryness and irritate respiratory systems.

Properly maintaining your HVAC system can help address these pollutants and improve your home’s indoor air quality.

Regular HVAC Maintenance for Better Indoor Air Quality

Routine HVAC maintenance can significantly impact your indoor air quality by:

  • Cleaning or Replacing Air Filters: Regularly inspect, clean, or replace your HVAC system’s air filters to prevent dust, debris and allergens from circulating through your home.
  • Sealing and Insulating Ductwork: Ensure all ducts are sealed and insulated to minimize air leaks and the entry of outdoor pollutants into your living spaces.
  • Scheduling Annual Checkups: Arrange for a professional technician to inspect and service your HVAC system annually to ensure optimal performance, while addressing potential IAQ issues.

Enhancing Indoor Air Quality with Additional Solutions

Incorporating supplementary solutions to your HVAC system can help improve indoor air quality, such as:

  • Installing an Air Purification System: Air purification systems can effectively remove contaminants such as pollen, pet dander and mould spores from the air in your home, resulting in cleaner, healthier air.
  • Utilizing Ventilation Systems: Properly installed and maintained ventilation systems, such as heat or energy recovery ventilators, allow for efficient air exchange, controlling humidity levels and enhancing overall IAQ.
  • Installing Humidity Control Options: Use humidifiers or dehumidifiers to maintain optimal humidity levels (between 30% and 50%) and prevent the growth of mould, mildew and other allergens.

Creating a Healthier Home Environment: Simple Tips

Beyond HVAC maintenance and enhancements, consider these practical tips to maintain a healthier home environment:

  • Regular Cleaning: Routinely clean your home, including floors, carpets and furniture, to remove dust, allergens and pollutants.
  • No Smoking Indoors: Prohibit smoking indoors to minimize the exposure to harmful toxicants emitted from tobacco products.
  • Limited Use of Harmful Chemicals: Minimize the use of household chemicals, such as cleaning products, paints and pesticides, which release VOCs into the air. Opt for natural and eco-friendly alternatives whenever possible.
  • Adequate Ventilation: Ensure your home is well ventilated, especially in high-humidity areas like bathrooms and kitchens. Open windows and use exhaust fans to minimize the accumulation of moisture and prevent mould growth.


Indoor air quality is a critical factor in maintaining a healthy and comfortable living environment for you and your family. Poor indoor air quality can lead to a range of health problems, including respiratory issues, allergies and asthma. Therefore, it’s important to understand the impact of indoor pollutants, maintain your HVAC system and implement additional solutions and practices to promote good indoor air quality.

Properly maintaining your HVAC system is another crucial factor in promoting good indoor air quality. Regularly changing air filters, cleaning ducts and scheduling annual maintenance can help ensure that your HVAC system is running efficiently and effectively. A well-maintained system can help filter out pollutants, regulate humidity levels and promote good air circulation throughout your home.

By understanding the impact of indoor pollutants, properly maintaining your HVAC system and implementing additional solutions and practices, homeowners in the Durham region, GTA and surrounding areas can create cleaner and healthier living spaces.
