Indoor Air Quality FAQs
Q: Why does indoor air quality (IAQ) matter?
A: IAQ matters because it describes how the air in your building affects occupants’ health, comfort, and ability to work. If your building has good air quality, the occupants will be healthy and comfortable, and they will work well. Poor indoor air quality can cause breathing problems and discomfort for building occupants, among other problems.
Q: Which HVAC factors contribute to good IAQ?
A: Your HVAC system should control inside and outside pollutants, have a good supply of fresh outdoor air, and maintain comfortable temperatures and humidity levels throughout your building. If it meets all these requirements, your HVAC system helps your building maintain good indoor air quality.
Q: What do signs of poor indoor air quality look like?
A: Signs of poor indoor air quality include:
- Poor building ventilation
- Excessive dust
- Dampness as a result of building or HVAC system leaks
- Contaminated air inside your building
- Occupants exhibit shortness of breath, headaches, fatigue, cough, dry eyes, or fever
Q: How can you tell if the IAQ causes health problems?
A: Ask your facility’s occupants when their symptoms occur. Do the symptoms go away when occupants go home? If they do, then your IAQ may need improvement.
Q: How can you tell if there’s an IAQ problem in your building?
A: Look for the signs listed above. If your building and its occupants exhibit those problems, reach out to your HVAC contractor. While there’s no single test that can diagnose poor IAQ in a building, your HVAC contractor can perform a walkthrough to examine your HVAC system’s condition. Then they can determine whether your HVAC system is contributing to poor air quality in your facility.
