Indoor air quality (IAQ) — how clean, fresh and healthy a building’s air is — directly affects the people who spend their days inside, from comfort and concentration to allergy, respiratory and infection risk. The building’s air systems are one of the main controllable factors in good IAQ. FreshDuct helps Melbourne buildings improve and maintain their indoor air quality by keeping the ducts, filters, exhaust and ventilation clean and performing.

Ventilation balance between fresh-air supply and exhaustA space receives fresh air on one side and exhausts heat, moisture and odour on the other; clean systems keep this balance, clogged systems cannot. Ventilation Is a Balance Fresh air in, heat & moisture out — clean systems keep up with the load Occupied space heat · moisture · odour generated Fresh air supply Exhaust out stale air Clogged ducts & fans cannot move enough air — humidity & odour build up
Ventilation works by balance: fresh air supplied in, and heat, moisture, odour and stale air drawn out. When the systems are clean they keep up with the load; when they are clogged, humidity and odour build up.

Why Indoor Air Quality Matters

People spend the great majority of their time indoors, breathing the air a building’s systems provide — so the quality of that air has a real effect on health, comfort and performance. Poor IAQ is associated with discomfort, headaches, eye and throat irritation, allergy and respiratory symptoms, reduced concentration and productivity, and in sensitive settings, infection risk. For workplaces, retail, hospitality, healthcare and education, IAQ is therefore a genuine concern for the people in the building, and increasingly something building owners and managers take seriously.

What Affects Building IAQ

A building’s IAQ depends on the cleanliness of its ductwork and air-handling systems, the condition and grade of its filters, how effectively exhaust removes moisture and stale air, how much fresh air the ventilation supplies, humidity and moisture control (and any mould), and the occupancy and activities inside. Many of these come back to how well the air systems are maintained — dirty ducts distribute contaminants, poor filters let particles through, weak exhaust leaves moisture and odour, and inadequate ventilation lets air go stale. Maintenance addresses the controllable factors.

How We Improve IAQ

We improve a building’s IAQ by addressing its air systems: cleaning the ductwork to remove distributed contaminant sources, servicing and upgrading filters to capture more particles, maintaining exhaust so moisture and stale air are removed, and keeping ventilation performing so fresh air is supplied. Where moisture or mould is involved, that is addressed too. We assess what is affecting the air, deliver the cleaning and servicing that improves it, and can maintain it on an ongoing program. See our duct cleaning guide.

Where IAQ Matters Most

IAQ matters everywhere, but most in buildings with vulnerable occupants or high occupancy: aged care and medical facilities, schools and childcare, offices, and hospitality and retail. High-occupancy and high-moisture environments warrant particular attention. For these buildings, IAQ is a health, wellbeing and sometimes compliance matter, and maintaining the air systems is a direct investment in the people inside. See our aged care and office guides.

A Measurable Difference

Improving IAQ is not abstract — occupants notice the difference between stuffy, stale, odorous air and air that is fresh and comfortable, and the effects show up in wellbeing, fewer complaints, and in sensitive settings, health outcomes. Clean, well-maintained air systems are what deliver that difference consistently. Treating IAQ as something to maintain, rather than react to, keeps a building’s air at its best year-round.

Frequently Asked Questions

What is indoor air quality and why does it matter for buildings?
Indoor air quality (IAQ) is the quality of the air inside a building — how clean, fresh and healthy it is for the people breathing it. It matters because occupants spend most of their time indoors, and poor IAQ is linked to discomfort, headaches, allergy and respiratory symptoms, reduced concentration and productivity, and in sensitive settings, infection risk. For workplaces, retail, hospitality, healthcare and education, IAQ directly affects the people in the building. Maintaining the air systems is one of the main controllable factors in good IAQ.
How does HVAC maintenance improve indoor air quality?
The building’s HVAC systems determine much of its IAQ: the ductwork distributes air (and any contaminants in it), filters capture particles, exhaust removes moisture and stale air, and ventilation supplies fresh air. When these are dirty or under-maintained, they distribute dust and contaminants, fail to remove moisture and odour, and supply poorly. Cleaning the ducts, servicing filters, maintaining exhaust and keeping ventilation performing removes contaminant sources and lets the systems do their job — which is how maintenance improves IAQ.
What factors affect a building’s indoor air quality?
Several: the cleanliness of the ductwork and air-handling systems; the condition and grade of the filters; how effectively exhaust removes moisture and stale air; how much fresh air the ventilation supplies; humidity and moisture control (and any mould); and the occupancy and activities in the building. Many of these come back to how well the air systems are maintained. We assess the systems and identify what is affecting IAQ and what to address. See our commercial duct cleaning guide.
Which buildings should pay most attention to IAQ?
IAQ matters everywhere, but most in buildings with vulnerable occupants or high occupancy: aged care and medical facilities (infection control and vulnerable patients), schools and childcare (children’s health), offices (staff wellbeing and productivity), and hospitality and retail (customer comfort). High-occupancy and high-moisture environments also warrant particular attention. For these buildings, IAQ is a health, wellbeing and sometimes compliance matter, and maintaining the air systems is a direct investment in it. See our aged care guide.
Can you assess our building’s indoor air quality issues?
Yes — if a building has IAQ concerns (stuffiness, odours, moisture, complaints, or simply a desire to improve), we can assess the air systems to identify what is contributing and what to address — the state of the ductwork, filters, exhaust and ventilation. From there we recommend the cleaning and servicing that will improve the air quality, and can build it into an ongoing program to maintain it.
