HVAC Diagnostic Services for Indoor Air Quality

DUCTZ Diagnostic Services are regularly analyzed by mechanical system specialists from the very best in the country. "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 and collect 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."

Indoor Air Quality (IAQ) Facts

The Environmental Protection Agency (EPA) lists poor Indoor Air Quality as the fourth-largest environmental threat to our country.
A staggering 42.6 million individuals nationwide suffer from asthma and/or allergies, or have other respiratory illnesses and may be at a greater risk of health complications associated with poor air quality in their homes. (American Lung Association).
5 out of 10 Americans are not aware of the health risk poor IAQ can pose, according to a study by the American Lung Association. Additionally, many Americans are not aware of the steps that can be taken to improve IAQ.

The benefits of HVAC system reconditioning:

Improve Indoor Air Quality

Wet portions of HVAC systems are notorious breeding grounds for biological contaminants. An annual inspection of a home's HVAC system will reveal the severity of contaminant levels within the system and the extent of cleaning necessary. Having an HVAC system reconditioned will remove allergens like dust, dander, insect remains, microbial growth and bacteria from the system and will, in turn, provide for a healthier environment to live or work in.

Optimize Energy Efficiency

A typical duct system (component of the HVAC system) will lose 25 to 40 percent of the heating or cooling energy put out by the HVAC system. Un-insulated, disconnected, torn, damaged or dead-end ducts are mainly responsible for that loss of energy. The cleanliness of the coil system in the main HVAC system is another crucial factor to a home's energy efficiency.

Increase System Longevity

The HVAC system is the most expensive mechanical system in your home, and replacing it can cost thousands of dollars and tremendous aggravation. Annual inspections and regular maintenance can prolong the life of an HVAC system by years.

What sets DUCTZ apart from the competition?

DUCTZ professionals do more than just duct cleaning. DUCTZ professionals restore HVAC systems, including all of the mechanical components, and bring the HVAC system to near-peak cleanliness for optimum system operation.

DUCTZ professionals utilize HEPA filters on vacuums and collection units during HVAC reconditioning to protect a home or business against recontamination during cleaning activities.

DUCTZ professionals hold patents for the foil lining technology used to resurface ductwork that is severely damaged by microbial growth, insects or bacteria.

As a member of the National Air Duct Cleaners Association (NADCA), DUCTZ professionals adhere to the association’s stringent HVAC cleaning requirements and Code of Ethics, which can be viewed at
