DUCTZ Diagnostic Services are regularly analyzed by mechanical system specialists from the very best in the country. We fully believe that “An ounce of prevention is worth a pound of cure.”

Researching an HVAC System’s Effect on Indoor Air Quality (IAQ)

When you need to know if a mechanical system contains microbial growth, bacteria, or other particulates, DUCTZ professionals can provide thorough, qualified analysis and reliable answers to your questions.

DUCTZ professionals analyze the mechanical systems, taking into account the environmental conditions such as temperature, relative humidity, moisture intrusions, water damage, building pressurization, carbon dioxide levels and fungal dispersion. Environmental conditions are directly linked to IAQ, as well as the overall performance and efficiency of the HVAC system.

DUCTZ professionals understand that not all IAQ issues relate to the mechanical systems; however, it is the best place to start. In fact, the EPA’s IAQ Design Tools for Schools recommend that schools and other commercial buildings follow specific guidelines when conducting a proper assessment of the mechanical systems. DUCTZ professionals comply with the latest EPA, NADCA and ACCA recommendations, as well as other state and federal recommendations.

As the EPA states from their An Office Building Occupant’s Guide to Indoor Air Quality Design, Maintenance and Operation of Building Ventilation Systems, “Maintaining good Indoor Air Quality requires attention to the building’s heating, ventilation, and air conditioning (HVAC) system; the design and layout of the space; and pollutant source management.

HVAC systems include all of the equipment used to ventilate, heat, and cool the building; to move the air around the building (ductwork); and to filter and clean the air. These systems can have a significant impact on how pollutants are distributed and removed.

HVAC systems can even act as sources of pollutants in some cases, such as when ventilation air filters become contaminated with dirt and/or moisture and when microbial growth results from stagnant water in drip pans or from uncontrolled moisture inside of air ducts.”
