Humidity Havoc: How Clean Air Ducts Combat Mold in July
July brings warm weather and increased humidity across Ontario, including cities such as Hamilton, Burlington, and Oakville. While the summer season is often welcomed, it also presents significant indoor air quality challenges—particularly due to the elevated risk of mould growth. High humidity levels create ideal conditions for mould spores to thrive within HVAC systems, leading to potential health risks and damage to residential and commercial properties. Regular air duct cleaning is a critical measure to combat this seasonal threat.
Understanding the Relationship Between Humidity and Mould
Humidity refers to the concentration of water vapour in the air. When indoor humidity levels exceed 60%, the likelihood of mould colonization increases substantially. This is particularly problematic in July, when outdoor humidity levels soar and indoor HVAC systems work harder to maintain comfortable temperatures.
Air ducts serve as conduits for airflow throughout a building. However, if they are clogged with dust, debris, or moisture, they can become breeding grounds for mould spores. The dark, enclosed spaces within ductwork provide the perfect environment for mould to grow undetected, especially in the presence of trapped moisture.
Health Impacts and Structural Risks
Mould exposure can have serious implications for occupants’ health. Symptoms may include respiratory irritation, nasal congestion, headaches, skin rashes, and in severe cases, long-term respiratory issues such as asthma. Children, seniors, and individuals with pre-existing respiratory conditions are especially vulnerable.
From a structural perspective, the presence of mould within ductwork can lead to widespread contamination. Once established, spores may be dispersed throughout the building each time the HVAC system is engaged, causing secondary infestations on walls, ceilings, carpets, and insulation.
The Role of Professional Duct Cleaning
Professional air duct cleaning is an essential preventive strategy. A certified duct cleaning service, such as that provided by Vacu-Man, ensures that all accumulated dust, allergens, and moisture are effectively removed from HVAC systems. Using industry-standard equipment and techniques, technicians eliminate the conditions conducive to mould growth.
Air duct cleaning also enhances HVAC efficiency. Clean ductwork allows for unrestricted airflow, reducing strain on heating and cooling systems and potentially lowering energy costs during peak summer months. Importantly, a properly maintained HVAC system supports consistent indoor humidity regulation—an often-overlooked factor in mould prevention.
