When it comes to testing your indoor air quality, you will need to see if your home’s air has dangerous levels of the following three pollutants:
Radon is the second leading cause of lung cancer next to smoking. Radon gas comes from radioactive uranium in the soil and travels upward through cracks in a home’s foundation or basement. If a home has a radon level above safe screening levels, it is strongly recommended that a radon mitigation system be installed.
Mold is one of the most common issues tested for during an IAQ test. Mold spores are ever-present and can collect on air filters, evaporator coils, ductwork, and HVAC system drip pans. If allergy or asthma symptoms seem to be worsening, it’s likely caused by an unmitigated buildup of mold.
Volatile Organic Compounds (VOCs) are dangerous chemicals found in homes and businesses. They can spread through contaminated water sources and through the air as vapor. Some common sources of VOCs include solvents, paints, air fresheners, aerosol sprays, and gasoline. If you’ve had work done in your home recently like painting or construction, you may want to consider duct cleaning to remove these chemicals from circulating in your home’s HVAC system.
