Air Duct Sealing & Cleaning targets the network of ducts that distribute conditioned air throughout a building. Even in modern ducted reverse-cycle systems, tiny gaps or poorly joined sections can allow moisture-laden air to infiltrate. Over time, dust, debris, and spores can accumulate, creating a perfect environment for mould to flourish—especially if the air conditioning is frequently running in humid Australian climates.
This service typically begins with an inspection to identify compromised areas in the ductwork. Technicians may use cameras or smoke tests to locate leaks or cracks. Once discovered, these gaps are sealed using specialized tapes or mastics that withstand temperature fluctuations and moisture. Concurrently, the interior surfaces of the ducts are cleaned using brushes, vacuums, and sometimes antimicrobial treatments that neutralize any mould present.
Sealing and cleaning the ducts not only boosts indoor air quality—by preventing spores from circulating—but also enhances energy efficiency. Leaky ducts force HVAC systems to work harder, leading to higher energy bills. For large commercial buildings like shopping centres or office complexes, the cost savings can be significant. Moreover, a cleaner, well-sealed duct system helps maintain consistent temperature control throughout the building, avoiding hotspots or cold zones. By keeping moisture out of the duct network, property owners can ensure that their air conditioning investment lasts longer, operates more efficiently, and, most importantly, doesn’t contribute to hidden mould issues.
