IAQ and preventive maintenance

The U.S. Environmental Protection Agency states that indoor air pollution may range anywhere from 5 to 100 times the level of outdoor pollution. Poor IAQ can lead to dizziness and headaches in building occupants and aggravate symptoms of allergies and asthma.

Conversely, good IAQ in commercial buildings can offer many benefits to businesses, including employee productivity, a decrease in absenteeism, enhanced performance levels and a more positive customer experience.

But keeping indoor air quality levels under control is not as simple as ensuring proper filtration and ventilation. Did you know there’s also a strong connection between ongoing maintenance of your customer’s HVAC system and improved IAQ?

In order to fight some of the root causes of poor IAQ—such as damp or poorly ventilated environments—an HVAC system must be running at peak performance because most of the air in the building will at some point pass through the HVAC system. Therefore, the inside air will be dramatically affected by the level of hygiene in the system.

When installing an HVAC system in a new or existing building or servicing an existing system, consider the following:

  • Perform proper preventive maintenance of coils and drain pains. Dirty coils and drain pans that do not work are two of the most common sources of odors and can offer a breeding ground for more serious IAQ issues.
  • Inspect intake and exhaust systems; ensure the system is properly designed.
  • Check filters regularly and change them as needed. Install high-efficiency air filters to protect against airborne particles and reduce concentrations of pollen, dust mites, dirt, mold, spores, fungi, odors and chemicals.
  • Ensure each area of the building is receiving the right amount of airflow. Pay special attention to areas near processing or manufacturing equipment and areas prone to chemicals, moisture and odors.
  • Install UVC germicidal lights in the building’s HVAC system to reduce concentrations of mold, bacteria and fungi on the coils; keeping coils clean will help maintain system efficiency, minimize irritants and increase overall comfort.
  • Keep humidity levels under control with a dehumidification system. Excess moisture can contribute to the growth of mold and bacteria. Lennox’ Humiditrol® dehumidification system features a patented design that controls humidity independent of room temperature, keeping the air comfortable at a lower set point while helping customers save on utility costs.

Lennox offers a wide range of IAQ products to help control humidity and provide ventilation. View our IAQ products.
