How can an inspector assess indoor air quality?

Assessing indoor air quality is crucial for ensuring a safe and healthy environment. The correct choice focuses on a comprehensive evaluation of factors that directly impact air quality. By checking for mold, allergens, ventilation issues, and carbon monoxide levels, an inspector can identify potential health risks and assess the overall air quality in the space.

Mold can significantly affect indoor air quality by releasing spores that may lead to respiratory problems. Allergens, which can include dust mites, pet dander, and pollen, are also vital to evaluate as they can trigger allergic reactions or asthma in sensitive individuals. Ventilation issues can lead to stagnant air, promoting pollutant accumulation and inadequate air exchange, while monitoring carbon monoxide levels is essential for detecting this odorless and potentially deadly gas, which can arise from malfunctioning appliances or inadequate ventilation in fuel-burning devices.

Other options provided do not encompass such an extensive assessment. Checking for recent renovations might indicate potential VOC (volatile organic compounds) or other emissions, but it does not give a complete picture of air quality conditions. Assessing temperature alone fails to address the wide range of pollutants and conditions that affect air quality. Determining the age of the HVAC system may provide some insight into its potential effectiveness, yet it does not provide information about the air
