Duct & exhaust cleaning facts in Sydney

Why is kitchen exhaust cleaning so important?

The exhaust gases created by cooking processes leave a greasy residue on the inside of ductwork. The heat removed by the exhaust system heats this residue, which causes a fire hazard. The three elements required for a fire are air, fuel and heat.

These three factors are present in the exhaust system, just waiting to ignite. A simple flare-up while cooking is all it may take. You may extinguish a fire in your cooking area, but the flare-up can also ignite the grease in the ductwork. This is not as easy to extinguish, as the ductwork usually disappears into the ceiling cavity.

Residue in the exhaust ductwork can potentially be food source for vermin, who enter the ductwork when it is not operational. All these problems can possibly send your business into a financial downward spiral.

How often should kitchen exhaust systems be cleaned?

Regular kitchen exhaust maintenance provides numerous benefits for your property and business:

  • Lowers the risk of financial loss caused by a serious fire.
  • Removes fire hazards.
  • Removes food sources of insects and rodents.
  • Complies with local fire and health regulations.
  • Complies with insurance requirements.
  • Brings peace of mind to you and your employees.
  • Improved internal and external appearance.
  • Lower electrical costs.
  • Improved equipment efficiency.
  • Improved operating capacity.
  • Prevention of costly breakdowns.
  • Extended equipment life.
  • Healthier indoor environment.

Why is HVAC cleaning 
so important?

What is the internal condition of your HVAC system? Your HVAC system is said to be the ‘lungs’ of your building. Air conditioning ducts are usually concealed out of sight. It filters the air, controls temperature and humidity and exchanges stale air for fresh air. Therefore, a dirty HVAC system is restricting your buildings ability to breathe and may even be infected. Indoor air quality is critical. It provides us with a safe, comfortable environment. Indoor air is often polluted, but we 
can help.
"Most people are aware that outdoor air pollution can damage their health, but many do not know that indoor air pollution can also have significant health effects. Environmental Protection Agency studies of human exposure to air pollutants indicate that indoor levels of pollutants may be 2-5 times, and occasionally more than 100 times, higher than outdoor levels. These levels of indoor air pollutants may be of particular concern because most people spend about 90% of their 
time indoors." 


Any surface within a building will accumulate dust when left uncleaned. This dust consists of bacteria, mould spores, pollen, dust mites, building material, pet hair, cooking oils, soot, paper and other particulate matter. Air moving through the air conditioning system will redistribute the contaminants back into the rooms we occupy.

It is estimated that the average 140 square metre home generates 18 kilogrammes of dust per year.

Dust mites, furry pets, cockroaches, mould and fungi often cause allergy triggers indoors. These allergies are the body's physical reactions to inhaled airborne particles called "allergens." By removing contaminants from your ducting systems, you also remove the source of the allergens.

10mm of dust in your ductwork can reduce efficiency by up to 21%.

A professional duct clean can easily add benefits to your building’s health and the operational costs of HVAC systems. The following are some areas where benefits are found:

  • Indoor air quality.
  • Healthier employees.
  • More productive employees.
  • Provides mitigation.
  • Reduced allergy symptoms.
  • Reduced asthma.
  • Efficient, clean duct work.
  • Decreased operation cost – reduces equipment’s workload.
  • Improved air flow – the removal of contaminants from ductwork reduces flow resistance.
