How Your Heating System Affects Your Air Quality

Your HVAC system affects your indoor air quality in several fundamental ways. It primarily circulates the air throughout your home, including any airborne particles present. Without proper maintenance, several issues can arise, leading to a decline in the quality of air you breathe.

Here are common ways your HVAC could be contributing to lower air quality:

  • Poor Filtration: A clogged or low-quality filter can fail to trap dust, pollen, and other irritants, allowing them to recirculate.
  • Duct Leaks: Gaps or holes in the ductwork can introduce and distribute pollutants from unconditioned spaces.
  • Humidity Imbalances: Inadequate humidity control can encourage the growth of mold and dust mites.
  • Stagnant Air: Without regular ventilation, indoor air can become stale, increasing concentrations of indoor pollutants.

Besides the HVAC-related issues, the lack of fresh air in homes during winter can exacerbate indoor pollution levels by trapping contaminants and irritants inside. Additionally, using combustion appliances (like gas stovetops), wood stoves, or fireplaces can further contribute to indoor air quality problems by releasing smoke and fine particles into the living space.
