FAQs
Why is regular duct cleaning important for my heating and air-conditioning system in Mascot?
Over time, dust, lint, pollen, pet dander and even mould spores can accumulate inside your ductwork. When your HVAC system runs, these contaminants are circulated throughout your home or business, aggravating allergies and reducing overall air quality. A professional duct clean removes this build-up, helping the system run more efficiently, lowering energy bills, extending equipment life and creating a healthier indoor environment for occupants.
How often should I have my ducts cleaned?
For most Mascot households and commercial premises, we recommend a thorough duct clean every 3–5 years. However, you may need more frequent servicing if you have pets that shed, family members with asthma or allergies, recent construction or renovation work, visible mould in the vents, or if you notice a musty odour when the system is operating. Our technicians can inspect your ducts and suggest a customised maintenance schedule.
What signs tell me my ducts need professional attention?
Common indicators include: noticeable dust blowing out of vents, unpleasant odours when the unit starts, inconsistent airflow or hot/cold spots, higher than usual power bills, allergy or respiratory symptoms that worsen indoors, and rattling or whistling noises from the ductwork. If you observe any of these, book an inspection to prevent further problems and energy loss.
What is included in your duct cleaning service?
Our Mascot duct cleaning package covers: a pre-clean inspection with cameras to assess contamination levels; removal and cleaning of supply and return registers; negative-pressure vacuuming of the full duct network; rotary-brush agitation to loosen stubborn debris; sanitising treatment to eliminate bacteria, mould and odours; cleaning of the blower fan, evaporator coil and accessible housing; final system performance test; and a detailed condition report with before-and-after photos.
How long does a standard duct cleaning appointment take and will it disrupt my day?
A typical residential job with 6–10 vents takes about 2–3 hours, while larger homes or commercial spaces may require half a day. We schedule appointments at times that suit you, protect floors and furniture with drop sheets, and keep noise to a minimum. Your heating or cooling system can usually be switched back on as soon as we finish, so downtime is negligible.
Are the products and methods you use safe for my family, staff and the environment?
Yes. We use hospital-grade, biodegradable cleaning solutions that are non-toxic and low in VOCs, making them safe for children, pets and sensitive individuals. Our high-powered vacuums are HEPA-filtered to capture 99.97% of particulates, preventing any contaminants from re-entering your indoor air. We adhere to Australian Standards AS/NZS 3666 and NADCA guidelines to ensure environmentally responsible and effective service.
