The Role of HVAC on Indoor Air Quality

When an HVAC system is poorly maintained, it can significantly degrade indoor air quality, leading to a range of health and comfort issues. Dust, mold, bacteria, and other contaminants can accumulate in the system, circulating throughout the building. This compromises the air quality and can also lead to a host of consequences, including the following:

• Increased Dust and Debris Circulation: A dirty HVAC system can accumulate dust and debris, which will be circulated throughout the building, making the air feel stuffy and dusty.

• Mold and Mildew Growth: Moisture buildup in HVAC components, such as the coils and ducts, can lead to mold and mildew growth, which worsens IAQ and can cause respiratory issues.

• Poor Ventilation: When an HVAC system is not properly maintained, airflow can become restricted, leading to inadequate ventilation and a buildup of stale air inside the building.

• Higher Levels of Allergens: Dirty filters and ducts can trap allergens like pollen, pet dander, and dust mites, allowing them to circulate and potentially trigger allergic reactions or asthma attacks.

• Increased Odors: Poor maintenance can cause dirt, bacteria, and mold to accumulate, producing unpleasant odors that affect the overall environment and comfort.

• Higher Energy Costs: A poorly maintained HVAC system uses more energy to function, leading to higher utility bills while failing to provide adequate indoor air quality.

• Worsened Respiratory Health: The buildup of contaminants in the system can directly impact respiratory health, leading to symptoms like coughing, wheezing, and shortness of breath.

It is essential to maintain your HVAC system to ensure a healthy, clean, and comfortable indoor air quality. To ensure our HVAC system is positively contributing to your space’s indoor air quality, be sure to schedule routine maintenance with SAM Mechanical Services.
