Duct Cleaning Melbourne is something that should happen every 3–5 years, depending on the type of air ducts in your home and the kind of use your heating and cooling system experiences. 

It helps to remove debris and prevent the growth of mould and mildew in your heating and cooling system, which can have adverse effects on the quality of air in your home as well as its functionality. 

Here are five signs that it’s time to call the professional duct cleaning to schedule an appointment for commercial duct cleaning in your office building or other business location.

1) Blocked Vents

Blocked vents can cause moisture and debris to accumulate, leading to mould and bacteria growth. This is a major health concern, not just because of the toxins in the air but also due to the risk of fire or explosions. 

The buildup also means that you’re wasting energy by allowing your heating and cooling system to work harder than it needs to. If your ducts are blocked, it might be time for our commercial Duct Cleaning Melbourne services!

2) Unusually Hot or Cold Temperatures

Commercial duct cleaning services should be leveraged at least annually, but it may be necessary to have the system cleaned more often if you experience unusually hot or cold temperatures in your building. 

For example, if you operate a business in a warehouse that is unheated during the winter, then your air conditioning system will work harder and produce more particulate matter than a typical building. 

Similarly, an unheated warehouse will collect water condensation on the ducts, which may lead to corrosion and mould growth.

3) Unusually Loud Noises Coming from Vents

One of the most common signs it is time to clean the ducts in your building when you hear unusual noises coming from the vents. 

If there are sounds like rattling, clanging, or even banging coming from the vents, that means that something inside has loosened and fallen loose. This can be anything from dust particles to leaves or small animals.

4) Black Dust in Air Ducts

The first and most obvious sign that it might be time to call in a professional who provides commercial duct cleaning services is the presence of black dust in your air ducts. 

There are many things that could be causing this, including the buildup of heating systems, pet hair, and dirt. If you can’t pinpoint what is causing the black dust, a professional should help!

5) Repeated Infections In The Office

Repeated infections in the office can be a sign that your commercial ducts need Duct Cleaning Melbourne. If you see an increase in colds, flu, and other illnesses in the office, it could be due to dust mites and other contaminants circulating through your HVAC system. 

To avoid these issues, make sure that your commercial ducts are cleaned twice a year–once during the heating season and again during the cooling season.
