What is Indoor Air Quality (IAQ)?

When most people think about their HVAC system, they think about temperature—keeping warm in the winter and cool in the summer. But Indoor Air Quality (IAQ) is about the health of the air you breathe inside your home.

IAQ refers to the condition of the air within and around your home as it relates to the health and comfort of your family. It involves more than just dust; it includes invisible pollutants like volatile organic compounds (VOCs) from cleaning products, allergens like pet dander and pollen, mold spores, and humidity levels.

Considering that the EPA estimates indoor air can be 2 to 5 times more polluted than outdoor air, paying attention to your IAQ is one of the most important things you can do for your home’s environment.

Benefits of Regular IAQ Assessments

Indoor air quality assessments offer numerous benefits for both residential and commercial spaces. They help identify potential sources of pollution, such as mold, VOCs, and allergens, allowing for targeted interventions that improve the air quality. These assessments also help you comply with health and safety standards, minimizing health risks and creating a healthier environment for you and anyone else in the space. 

Maintaining good indoor air quality can enhance productivity and comfort, reducing issues like fatigue and allergies, which can impact daily activities. By addressing these concerns promptly, regular assessments ensure sustained well-being and quality of life.

Common Indoor Air Pollutants and Their Impact

Indoor air can contain pollutants that significantly impact our health. Dust mites, pet dander, and mold spores can trigger respiratory issues and allergies, making it difficult for you to feel comfortable in your own home. Mold spores can thrive in damp areas, exacerbating respiratory conditions and leading to chronic health problems. 

Volatile organic compounds (VOCs) emitted from household products and furniture can also contribute to poor air quality, leading to headaches, nausea, and other symptoms. 

It’s important to recognize these common pollutants and their effects to maintain a healthier indoor environment. Regular assessments can help identify these issues early, allowing for timely interventions that reduce health risks and improve overall well-being.

Why IAQ Matters in Winter

Winter presents a unique and difficult challenge for your home’s air quality. To keep energy bills down and heat in, we tend to keep windows and doors tightly sealed for months at a time. While this is great for efficiency, it creates a “sealed box” effect where fresh air cannot enter, and pollutants like cooking fumes, pet dander, and viruses are trapped inside and recirculated endlessly.

Furthermore, cold winter air naturally holds very little moisture. When your furnace heats that already dry air, humidity levels in your home drop significantly. This lack of humidity dries out your skin and nasal passages, making you more susceptible to respiratory infections, while simultaneously causing static electricity and potential damage to wood floors and furniture.
