FAQs
Why is regular duct cleaning important for my heating and air-conditioning system?
Dust, pollen, pet dander and even construction debris can accumulate inside your ductwork, forcing your heater or air-conditioner to work harder to push air through the system. This leads to higher energy bills, uneven temperatures and premature wear on expensive components such as fans, burners and coils. Professional cleaning removes these blockages, restoring proper airflow, lowering operating costs and helping your equipment last longer. In Mascot’s coastal environment, where salt and humidity can accelerate corrosion, keeping ducts clean also helps prevent rust and mould growth.
How often should I have my ducts cleaned in Mascot’s climate?
Industry guidelines recommend a full duct clean every 3–5 years for an average household, but local factors can shorten that interval. Mascot’s proximity to Sydney Airport means homes and businesses are exposed to higher levels of aviation soot and outdoor pollutants that get drawn into HVAC systems. If you have pets, smokers, a recent renovation, or occupants with asthma or allergies, we suggest inspecting the ductwork annually and cleaning every 2–3 years to maintain healthy indoor air quality.
What signs indicate my ducts need professional cleaning?
Common red flags include persistent musty or dusty odours when the system starts, visible dust puffs from supply vents, an unexplained increase in allergy or respiratory symptoms, uneven airflow between rooms and a noticeable rise in energy consumption. You may also see dark marks around vent edges, signalling that airborne contaminants are bypassing the filter and sticking to the grille. If you notice any of these symptoms, scheduling an inspection is advisable.
What does your duct cleaning process involve and how long does it take?
Our certified technicians follow NADCA and AS 3666 best-practice standards. We begin with a camera inspection to locate problem areas, then isolate each branch of the ductwork so debris isn’t distributed throughout the property. A high-powered negative-air vacuum is attached to the main trunk line while rotating brush whips dislodge dust, mould and debris. We finish with an antimicrobial fogging treatment (optional) to inhibit future microbial growth. A typical Mascot home with 8–10 vents takes 2–3 hours; larger commercial systems may require a full day or weekend shutdown to minimise business disruption.
Will duct cleaning really improve indoor air quality and energy efficiency?
Yes. Studies by the U.S. Environmental Protection Agency show that removing heavy build-ups in ducts can cut total HVAC energy usage by up to 11 %. Clearer ducts allow conditioned air to reach rooms faster, so thermostats cycle off sooner. Just as importantly, removing bio-contaminants such as mould spores, bacteria and dust mites reduces airborne irritants that trigger asthma and allergies. Many Mascot clients report noticeably fresher air and fewer dusting chores after a single service.
Are your duct cleaning methods safe for pets, children and people with allergies?
Absolutely. Our vacuums are HEPA-filtered to capture 99.97 % of particles down to 0.3 µm, preventing contaminants from re-entering your living space. If you choose the antimicrobial treatment, we use hospital-grade, water-based solutions that are non-toxic, low-odour and approved by the Therapeutic Goods Administration (TGA). We recommend pets and sensitive individuals remain outside the treated area for 30 minutes while the fog settles; after that, it’s completely safe to re-occupy the rooms.
