5 Best Air Duct Cleaning Services in Sydney (2026)

Independently ranked by our review of ratings, reviews and reputation · How we chose

By Brad Smith, Home Services Expert · ✓ Data verified August 2026 · 8 min read

A musty smell blowing out of the vents usually means one thing: nobody has touched the ductwork in years. Sydney's top-rated air duct cleaning services carry a combined 1,306 Google reviews, and every one of them sits at 4.7 stars or higher, so the harder question is which crew actually cleans ducts rather than just the unit sitting on your wall.

Short answer: The top-rated pick for actual duct work is CB Climate Control (4.9 stars, 411 reviews), with Smartway Air Conditioning close behind at a perfect 5.0 across 319 reviews. Both clean and service ducted systems directly rather than just the indoor unit. Expect quotes to vary by system size, and always confirm the job covers the ductwork itself before booking.

Who to call, and for what

#1 Overall🕑 Open 7 days↩ Responds to reviews

CB Climate Control

4.9411 Google reviews

CB Climate Control is a Sydney air conditioning contractor that installs, services and repairs ducted and split systems across the city. Its technicians handle everything from replacing ageing ducted units to fixing sensor faults and sealing gaps around outdoor units, and the company runs a large residential base built almost entirely on word of mouth. It is not a duct-cleaning specialist by name, but its day-to-day work is squarely inside the ducted systems homeowners are trying to keep clean.

What people praise

Technicians explain the fault and the fix before starting
Crews leave the work area tidy after installs and repairs
Prompt scheduling, often within the same week
Handles both routine servicing and full unit replacement

Worth knowing

Focused on ducted AC systems rather than dryer vents or general ductwork

Our take: The most-reviewed name on this list and the strongest fit if the job is your ducted air conditioning itself, not just a surface wipe-down. Confirm up front whether you need a repair, a clean, or both.

What people praise

Perfect 5.0 rating across 319 reviews
Technicians (Marco, Ethan) named repeatedly for clear explanations
Fixes small issues found during the clean at no extra callout
Punctual, tidy work

Our take: The top-rated pick here, and reviewers specifically describe a filter or unit clean rather than a full system service. Good for a straightforward freshen-up rather than ducted infrastructure work.

SleepClean mattress sanitising

5.0198 Google reviews

SleepClean is a Sydney mattress, carpet and upholstery cleaning company, Google's own category for it is carpet cleaning, not air duct cleaning. It uses dry steam cleaning on mattresses, sofas and carpets, and its technicians will move furniture to clean underneath it. Every review on file talks about mattresses, lounges or carpets. None mentions air ducts, vents or an HVAC system, which means it is on this page by search overlap rather than by trade.

What people praise

Reviewers praise Agostino by name for honesty and thoroughness
Technician turned down unnecessary work and did not charge for it
Chemical-free process, popular with pet owners
Clear communication ahead of each appointment

Worth knowing

Does not appear to offer air duct cleaning based on its own site and reviews

Our take: A genuinely well-reviewed mattress and carpet cleaner, but not an air duct specialist. If ductwork is what you need cleaned, this is not the business for that job, however good it is at its own.

5.0168 Google reviews

Eco Aircon Cleaning is a Sydney aircon and chimney cleaning company that specialises in deep-cleaning split-system units, with chimney sweeping and dryer vent work also on offer. Its technicians strip units down to remove mould and dust buildup rather than just wiping the visible panel, and reviewers describe noticeably fresher air and quieter running units after a visit.

Perfect 5.0 rating across 168 reviews
Technicians (Tony, Tom) explain the process clearly on-site

Our take: A solid choice for a genuine split-system deep clean rather than a surface service, and the closest thing on this list to true air duct and vent cleaning outside of Real Time.

Real Time Air Duct & Aircon Cleaning

4.7210 Google reviews

Real Time Air Duct & Aircon Cleaning is the only business on this page whose sole listed service is air duct cleaning. It cleans ducted vents, replaces filters and services outdoor units, and reviewers describe full ducted systems being cleaned vent by vent rather than a single indoor unit. The company also offers weekend and after-hours appointments.

What people praise

The clearest specialist match for air duct cleaning on this list
Technicians walk customers through the process step by step
Weekend availability
Reviewers report noticeably fresher air after a full duct clean

Worth knowing

One reviewer reported no follow-up after asking about a separate ducting repair
Rating sits lower than the rest of the list at 4.7

Our take: The most direct fit if the job is specifically your ducted vents, since it is what the company was built to do. Get a clear scope of what is included before the crew arrives, since one reviewer felt the aftercare on a related repair fell short.

How we score

Every number on this page comes from public Google data on the date shown, not opinion or payment. Rating is the business’s live Google star average. Review volume shows how many customers have rated them, ranked against other Sydney duct and aircon cleaners. Confidence weighs the rating by that volume, so a 4.9 from hundreds of reviews carries more weight than a 5.0 from a handful. Recency reflects how recently people are still leaving reviews. No business can pay to change these numbers.

How much does air duct or aircon cleaning cost in Sydney? (2026)

None of the businesses on this page publish a fixed price list for duct or aircon cleaning, and job cost depends heavily on the number of vents, system size and access. Ask each company for a written quote based on your specific system before booking.

Serving all of Sydney

These companies cover Sydney’s inner city and surrounding suburbs, including the CBD, Inner West, North Shore and Eastern Suburbs. Searching for air duct cleaning near me? Every listing below shows a live phone number so you can check coverage for your exact address.

What to ask before you book an air duct clean

Does the service clean the ducts themselves, or just the indoor unit and filter?
How many vents or outlets does the quote cover?
Is there a warranty or callback if the issue (smell, noise) isn’t resolved?
Will you show before-and-after photos or footage of the ducts?
Is the quote flat-rate, and does it change based on ceiling access?

Frequently asked questions

How did you choose these businesses?

We started from every Sydney business with a public Google presence matching air duct and aircon cleaning, then ranked by rating, review volume, consistency and recency. See How we score above.

Are these rankings paid?

No. Rankings come from the public Google data in the scorecard. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position on the underlying data.

How often is this updated?

The data carries a verified date (August 2026 on this page). We refresh listings periodically so ratings and review counts stay current.

Is air duct cleaning the same as aircon cleaning?

Not always. Some businesses here, like Real Time, focus on cleaning the ducted vents themselves. Others clean the indoor or outdoor unit and filter without necessarily servicing the ductwork. Ask exactly what’s included before booking.

Why is a mattress cleaning company on this list?

SleepClean shows up in Google’s data for this search category, but its own reviews and website describe mattress, carpet and upholstery cleaning, not air ducts. We’ve kept it listed and described it honestly rather than leaving it off.

The bottom line

CB Climate Control and Smartway are the safest defaults if your job is a ducted or split system that needs servicing or cleaning, while Real Time is the closest thing to a pure air-duct specialist on this list. Ask exactly what’s covered by the quote before anyone shows up.
