HVAC Hygiene is more than just a process, it is a niche’ Indoor air quality service within Airconstruct H.V.A.C that we call Airhygiene. We realized in 2008 that HVAC Hygiene should be a part of any HVAC contractors core business so began a journey of self education and investment in equipment.
We are passionate about indoor air quality which is why I have invested substantially in our Indoor Air Quality remediation and testing equipment and developing processes for our team which exceed NADCA requirements.
We see ourselves as the custodians of the air people breath in buildings, so we approach our work with diligence and due care.
Our RTO application for our training company wwww.airhygienetraining.com.au is well underway and with the expected A.S.Q.A. approval timeline, we will be training and issuing these certificates by September 2021.

In the State of Queensland, HVAC Hygiene and Remediation work is classed as Mechanical Services – airconditioning works, and anyone undertaking this work is required to be appropriately licenced with the Queensland Building Construction Commission.
It is generally recognised that Australians spend 90% or more of their time indoors either relaxing or working. Until recently relatively little research has been done on the quality of air in our homes, offices, schools, recreational buildings, restaurants, public buildings or even inside cars.
Less than acceptable indoor air quality can result in significant adverse impacts on our health and environment. Furthermore these impacts carry significant cost burdens to the economy. The C.S.I.R.O. estimates that the cost of less than acceptable indoor air quality in Australia may be as high as $12 billion per year. In recent years comparative risk studies performed by the US EPA and its Science Advisory Board have consistently ranked indoor air pollution among the top five environmental risks to public health.
The National Health and Medical Research Council (NHMRC) define indoor air as; “Air within a building occupied for at least one hour by people of varying states of health”
This can include the office, classroom, transport facility, shopping centre, hospital and home. Indoor air quality can be defined as the totality of attributes of indoor air that affect a person’s health and wellbeing.
As commercial buildings and dwellings have become better sealed from the external environment, pollutants being released from indoor sources are being found at higher concentrations.
Indoor air quality can be adversely affected by other pollutants such as fungi, microbial contamination, house dust mites, particulates and air toxics such as formaldehyde and other volatile organic compounds.
Investigating and resolving indoor air quality problems can be complex.
However identifying the likely cause and controlling it should minimise health and comfort concerns and maintain or increase productivity. The Building Manager may choose to employ a Mechanical Services contractor who has an in-house specialist in this field or an Occupational Hygienist to conduct the indoor air quality investigation.
In the case of commercial premises, it often begins with a walk through inspection to gather information using our Greywolf IAQ analyser to see what the internal conditions are like, if they are conducive to mould and what are the temperature humidity and C02 levels. We may survey the building occupants and their locations, movements, tasks, and note any symptoms they may be experiencing. We then carefully examine the inside of the building’s air conditioning and ventilation systems to discover what possible contaminants could be present, which often involves taking samples for laboratory testing and determining how people could be exposed in order to formulate corrective actions.
