Introduction

Indoor air quality is no longer just a health consideration—it's a priority. In cities like Melbourne, where climate fluctuations are frequent, HVAC systems often work overtime. As a result, air ducts accumulate dust, allergens, and even mould, making regular cleaning a must. But how much should you expect to pay for these services? Understanding the cost of duct cleaning services in Melbourne will help you make informed decisions that protect both your home environment and your budget.

This blog takes a deep dive into real pricing, what affects those costs, and how you can get the best value for your money. If you're considering a duct cleaning service in 2025, this guide will help you avoid hidden fees and spot overpriced quotes—arming you with the knowledge to choose wisely.

What Influences the Cost of Duct Cleaning Services in Melbourne?

1. Size of Your Property

The square footage of your home or commercial building is one of the most significant cost drivers. Larger homes naturally have more vents and a more complex duct network, which means more labour and time.

• Small homes or apartments: $200–$300

• Medium-sized houses: $300–$500

• Large homes or commercial properties: $500–$1000+

2. Number of Vents and Ducts

Most professional companies charge per vent, especially for smaller jobs. The average cost per vent in Melbourne ranges from $25 to $40. If your home has 10–15 vents, you can expect to pay $300–$600.

3. Level of Contamination

If your ductwork contains significant dust build-up, pest infestation, or mould, the price will increase. Mould treatment, for example, can add $150–$300 to the overall bill.

4. Access and Complexity

Is your duct system easy to reach? Attic ducts, multiple HVAC zones, or tightly packed crawlspaces can make the job harder, raising labour costs by 15–30%.

5. Additional Services

Some providers offer bundled services like deodorising, filter replacement, or HVAC maintenance checks. While optional, these services can improve system performance and indoor air quality, costing an extra $50–$150.

Hidden Costs to Watch Out For

Some low-cost advertisements may seem appealing, but often exclude necessary fees. Here are hidden charges to look out for:

• Call-out fees: Often not included in the base quote.

• Mould treatment or pest removal: Typically billed separately.

• After-hours or weekend surcharges: Can increase the bill by up to 20%.

• GST not included: Always confirm if GST is part of the quote.

Ensure that your chosen provider offers a written, itemised quote to avoid these pitfalls.

Is Duct Cleaning Worth the Investment?

Absolutely. According to the Australian Department of Health, poor indoor air quality contributes to 1 in 9 cases of respiratory illness. Regular cleaning:

• Reduces allergens and airborne pollutants

• Enhances HVAC efficiency by up to 20%

• Prolongs system life

• Lowers energy bills over time

The initial investment in duct cleaning services in Melbourne often pays for itself in energy savings and fewer repair bills within a year.

How to Get the Best Value

1. Compare at Least Three Quotes

Don’t settle for the first estimate. Comparing providers ensures you get competitive pricing and exposes you to a variety of service offerings.

2. Read Reviews and Ask for References

Online reviews on Google and local directories can reveal a lot about reliability, punctuality, and professionalism.

3. Check for Industry Certifications

Look for companies certified by NADCA (National Air Duct Cleaners Association) or IICRC. These accreditations indicate a higher standard of quality.

4. Ask for an On-Site Inspection

Avoid quotes given purely over the phone. On-site inspections help eliminate surprises and result in more accurate pricing.

5. Bundle Services for Savings

If you need other maintenance services, ask about bundling HVAC inspections, dryer vent cleaning, or filter replacements. Bundles can save you 10–15%.
