What are typical indicators of poor indoor air quality?

Increased allergy symptoms are a typical indicator of poor indoor air quality because allergens such as dust mites, mold spores, pet dander, and pollen can accumulate in indoor environments, particularly when ventilation is inadequate. When the air quality is compromised, these allergens can irritate the respiratory system, leading to heightened allergy symptoms such as sneezing, coughing, and sinus congestion.

This relationship is crucial as it highlights the impact of environmental factors on health, which is often a primary concern in HVAC considerations. By recognizing increased allergy symptoms as a signal of potential air quality issues, HVAC professionals can diagnose underlying problems such as insufficient filtration, poor ventilation, or the presence of moisture that may promote mold growth. Addressing these indicators is essential for improving indoor air quality and ensuring a healthier living environment.
