Indoor Air Quality Testing

Protect yourself and occupants with regular IAQ (Indoor Air Quality) inspections, ensuring ongoing compliance of your building and HVAC System. Our Clean-Air IEPs (Indoor Environmental Professionals) can deliver specific IAQ solutions based on advanced testing analysis supported by NATA accredited labs.

ⓘ Mould Remediation Services for HVAC

Our IICRC certified mould remediation technicians can identify, test and remove mould from your HVAC systems, walls and ceilings. As well as provide preventative measures and long term solutions.

There are Australian Standards including AS/NZS 3666 & AS 1851 which are referenced in Workplace Health & Safety requirements including the Queensland Work Health and Safety Act 2011 and the Work Environment and Facilities Code of Practice 2011. These require regular inspection and reporting on the status of HVAC systems. IAQ Testing allows for accurate and recordable data to be accumulated with a continuing history about the indoor environment and in the event that issues or complaints arise they can be addressed promptly and fairly.

Clean-Air performs professional Indoor Air Quality Tests

Standard IAQ Tests
Temperature, Humidity, Carbon Dioxide (CO2) & Carbon Monoxide (CO).

Microbiological Tests
Surface Swab and Air Sampling which is then tested and reported for Mould, Bacteria & Yeast by an Independent NATA certified Laboratory.

Advanced IAQ Tests
Testing as above with additional requirements in VOCs (Volatile Organic Compounds), Sulphur Dioxide, Asbestos Fibres, Suspended Particles or other specified contaminants.

All Clean-Air Sample Testing is supported by NATA Approved Labs.

Health Research

Millions of people have allergies, and mould is a common irritant. Mould is also a known trigger of asthma. Symptoms of exposure to mould can be as basic as nasal congestion or watery eyes but in some cases, symptoms can be much more serious. Certain types of mould give off mycotoxins that can be the source of severe health issues and complications.

Symptoms of mould exposure range from:

  • Headache, fatigue, shortness of breath
  • Sinus congestion, coughing and sneezing
  • Eye, nose, throat and skin irritation
  • Dizziness and nausea
Not everyone has the same sensitivity to mould so it is possible for one person to experience discomfort while others in the building or office present no symptoms whatsoever. Individuals at the greatest risk include:

  • Allergy and asthma sufferers
  • People with respiratory disease
  • People with compromised immune systems
  • Contact lens wearers

While mould exists everywhere, it sometimes takes on a dangerous form. The scientific name for the greenish-black mould that turns up on the carpet, wallpaper, ceiling tiles, air conditioners – even wet leaves – is Stachybotrys Chartarum. It produces a mycotoxin that causes mycotoxicosis, and is thought to be the cause of “sick building syndrome”. Strong associations have been made between mould and various adverse effects on human health. Many are known to cause allergies such as hayfever; some are known to be important triggers of asthma.

Tests conducted on building occupants suffering allergic symptoms reported responses to fungi found in air conditioning ducts. A 1994 study found that repeated exposure to spores or other parts of fungi commonly found in indoor air could result in allergies such as asthma and rhinitis; extrinsic allergic alveolitis (a group of lung diseases) or hypersensitivity pneumonitis, which has flu-like symptoms; ‘sick building syndrome’ including symptoms such as headache, fatigue and mucosal complaints; or organic dust toxic syndrome recognised by tightness of the chest, bronchitis and asthma. Those with impaired immune systems are most at risk.

The results of work conducted in Australian homes, hospitals and other air-conditioned buildings indicate fungi are an indoor pollutant of significant concern.

If your air conditioner is contaminated you are at risk. Clean-Air IEPs can assess, scope and remediate the source of these issues and neutralise the risk to your building occupants or employees.

Despite an image as the nation which loves the great outdoors, Australians spend some 90% of their time indoors. As a consequence, indoor air quality and the health problems created by contaminated air are issues of very significant community health concern. It is now well documented that poor indoor air quality leads directly to a number of worrying health effects on the occupants of affected buildings. These range from minor skin and eye irritations to asthma, allergies, respiratory complaints and suppression of the immune system. Legionnaires Disease is just one deadly example.

A World Health Organisation report in 1995 estimated that up to one-third of buildings in industrialised countries are so-called sick buildings. In Australia, the CSIRO concluded in 1998 that this problem cost 12 billion dollars per year in lost productivity and illness. The issue of air quality is one with very real health and economic implications. It is with good reason that this topic is now among the most hotly debated in the environmental medical literature.

While we all enjoy the comforts afforded us by modern air conditioning systems, it is important at the same time that we recognise them as a source of potentially harmful micro-organisms and take steps to ensure that they are properly operated and maintained. By simply ensuring that the air delivery systems in modern buildings remain free of biological contamination, we can go a long way towards improving the health and quality of our indoor environments.
