As air cycles through your building, by way of your HVAC system, it passes through a series of filters, air is cooled and cleaned, and the space is ventilated. Some air conditioning systems will also humidify or dehumidify the air and heat it as well. Duct cleaning services are to remove dust, mould, bacteria and other contaminants that build up on the surfaces of this equipment – preventing those contaminants from being recirculated throughout the building. Regular inspection and cleaning will also help stop dust, biofilm and moisture from corroding your HVAC system components.

Benefits of commercial duct cleaning:

  1. Creates a more hygienic indoor environment. The real costs of poor indoor environment quality are much larger than first expected, with CSIRO estimating it costs Australia as much as $12 billion per year.
  2. Removes mould smells and other unpleasant odours. Occupants can be exposed to potential health hazards from breathing in bacteria, mould, or VOCs, (volatile Organic Compounds) such as, benzene, formaldehyde or residual tobacco smoke as air circulates through your building. Regular inspection and cleaning will reduce the potential for contaminants to accumulate in your HVAC system and be released into your building spaces.
  3. Improves building efficiency and lowers energy costs. As dust and moisture build up on HVAC components it can degrade the performance of air flow and efficiency of heat transfer. Australia’s Department of Climate Change and Energy Efficiency estimates proper maintenance and operation of HVAC systems can bring utility cost savings of 10–40%.
  4. Increases lifetime of HVAC components. If left unchecked, dust and moisture will cause corrosion and rust on HVAC components and equipment. Cleaning and coating will provide protection against contaminants and help extent that life of HVAC components.

With the complex nature of HVAC systems and their impact on indoor air quality in mind, Air Restore offers site-specific duct cleaning services and tailored recommendations for our clients. Our technical staff are mobile, and happy to conduct an obligation-free site inspection to assess your current HVAC contamination issues, scope out your project requirements and provide an accurate quote.

What are the typical contaminants in a HVAC system?

We commonly talk about dust, pollen, mould, bacteria and fungus when it comes to HVAC systems. It’s also common to find construction related dust and debris – plaster, fiberglass particles, plasterboard, timber and mdf dust.
The contaminants in your HVAC system will really depend on the activities that on the environment that you’re working in.
For example in veterinary clinics there will be a higher level of pet dander (skin flakes), hair, insects and … bacteria’s are more likely to be … and …compared to an office building that’s more likely to have… .

How often do I need to get my HVAC ducts cleaned?

Your HVAC duct cleaning schedule should be developed specifically for your site.
The thing is there are a lot of variables that will impact your HVAC cleaning schedule. The only real way to determine your duct cleaning schedule is by inspecting it regularly. You can carry out the inspection yourself, in fact we recommend that it be included in your system or building maintenance schedule. Please be aware that this inspection and assessment of HVAC Hygiene doesn’t override essential services or maintenance requirements that apply.
