The Importance of Indoor Air Quality Testing
Indoor air pollution is a growing concern for homeowners and business owners alike. Many people assume that staying indoors keeps them safe from pollutants, but in reality, indoor air can be up to five times more polluted than outdoor air. Dust, pet dander, mold spores, volatile organic compounds (VOCs), and even carbon monoxide can accumulate in enclosed spaces, leading to serious health risks.
Poor indoor air quality can contribute to:
- Respiratory Issues: Poor air quality worsens asthma, allergies, and chronic bronchitis by increasing exposure to pollutants like dust, mold, and chemicals. Irritants inflame airways, causing difficulty breathing, coughing, and wheezing. Vulnerable individuals experience heightened symptoms, requiring medical attention. Prolonged exposure may lead to long-term lung damage and decreased respiratory function, making clean air essential.
- Fatigue & Headaches: Polluted air triggers dizziness, nausea, and headaches due to exposure to carbon monoxide, volatile organic compounds (VOCs), and allergens. Poor ventilation increases indoor pollutants, reduces oxygen levels, and causes brain fog and fatigue. Chronic exposure impacts concentration, productivity, and overall well-being making proper air circulation and filtration crucial for maintaining good health and mental clarity.
- Increased Illnesses: Bacteria, viruses, and mold thrive in poor air quality, spreading infections and respiratory diseases. Mold spores trigger allergies and asthma, while airborne pathogens increase flu and cold risks. High humidity and stagnant air worsen microbial growth. Regular air purification, proper ventilation, and humidity control help prevent illness and maintain a healthier indoor environment.
- Unpleasant Odors: Musty, stale, or chemical odors signal hidden air quality issues like mold growth, off-gassing chemicals, or stagnant air. Persistent smells indicate high VOCs, moisture problems, or poor ventilation. Addressing sources like leaks, inadequate airflow, and dirty filters eliminates odors, improves indoor air freshness, and reduces potential health risks linked to airborne contaminants.
- Reduced HVAC Efficiency: Dust, debris, and pollutants clog filters and ductwork, making HVAC systems work harder, reducing efficiency, and increasing energy costs. Blocked airflow strains components, leading to breakdowns and shorter system lifespans. Regular maintenance, including filter replacement and duct cleaning, improves airflow, enhances efficiency, lowers costs, and ensures cleaner, healthier indoor air.
Regular air quality testing helps detect hidden air pollutants before they impact your health and comfort. We provide thorough evaluations to ensure your indoor environment is safe, clean, and conducive to a healthier lifestyle.

What Our Air Quality Testing Includes
At Hely Heating and Air Conditioning Co., we take a comprehensive approach to air quality testing. Our expert technicians use advanced diagnostic tools to evaluate multiple air quality parameters, ensuring a complete assessment of your indoor environment.
Our air quality testing services include:
- Particulate Matter (PM) Detection: Airborne particles like dust, pollen, and mold spores can aggravate allergies and respiratory conditions. Monitoring PM levels helps identify pollution sources and improve air filtration. High PM concentrations contribute to lung irritation and long-term health risks, making detection essential for maintaining a clean and healthy indoor environment.
- Carbon Monoxide (CO) Testing: CO is an invisible, odorless gas that can cause dizziness, nausea, and even death at high levels. Testing for CO ensures safety by detecting leaks from appliances like furnaces and stoves. Proper ventilation and CO detectors help prevent poisoning, making regular testing crucial for household and workplace health.
- Humidity Level Assessment: Excess moisture encourages mold growth, while low humidity causes dryness and respiratory discomfort. Measuring indoor humidity levels ensures a balance between comfort and safety. Ideal moisture (30-50%) prevents mold, reduces allergens, and enhances air quality, making a controlled indoor environment healthier and more comfortable.
- Volatile Organic Compounds (VOC) Testing: VOCs are harmful chemicals released from paints, furniture, and cleaning products, affecting indoor air quality. Testing identifies toxic compounds that can cause headaches, respiratory problems, and long-term health risks. Proper ventilation, air purification, and selecting low-VOC products help reduce exposure and maintain a safer living space.
- Mold & Mildew Analysis: Mold spores and microbial contaminants can cause allergies, asthma, and structural damage. Identifying mold presence helps mitigate health risks and prevent property deterioration. Proper moisture control, ventilation, and remediation reduce mold-related issues, ensuring cleaner indoor air and protecting both occupants and buildings.
- Airflow & Ventilation Testing: Efficient HVAC systems circulate and filter air, reducing contaminants and maintaining comfort. Testing airflow ensures adequate ventilation, preventing stale air and pollutant buildup. Proper ventilation enhances oxygen levels, removes toxins, and supports overall indoor air quality, contributing to a healthier and more energy-efficient environment.
- Radon Testing (Optional): Radon is a radioactive gas linked to lung cancer that seeps into buildings from soil. Testing determines exposure levels, guiding mitigation efforts to reduce health risks. Since radon is undetectable without specialized equipment, routine testing is essential for ensuring a safe indoor environment, particularly in areas with high radon concentrations.
