If you’ve been wondering whether mould can grow in an HVAC system, unfortunately the answer is yes. There are two main reasons why mould might grow in an HVAC system: moisture caused by condensation, and debris for mould to feed on. Mould in your HVAC system is not only a potential health hazard but can also cause extensive damage to the system itself. In this blog post, we will explore the causes of mould in HVAC systems, and provide tips on how to clean it up. We will also discuss the signs that you may have mould in your HVAC system, so that you can take corrective action as soon as possible.
Moisture in Air Ducts
When humid air passes through the cold coils of an air conditioner, it can condense and form water droplets. If this water is not properly drained, it can collect in the air ducts and create the perfect conditions for mould to grow. In this way, your HVAC system can cause mould to grow in your home. Air duct condensation can be a particular problem in Canada's more humid seasons, which makes addressing the problem early on that much more important. To prevent mould and ensure that condensation is draining properly, check and clean your unit's coils regularly. You should also check the drain pan to ensure that it is not full of water. If it is, empty it out and clean it with a mild bleach solution. You may also need to check and clear drain lines, which is something a professional service tech can help you with.
Can Mould Grow in HVAC System?
In order for mould to grow, it needs a food source. Debris in your air ducts can provide this food source and is often the cause of mould growth in HVAC systems. This debris can include things like dust, pollen, pet hair, and even skin cells. Canadian weather is often at least partly responsible for dust and other debris collecting in your air ducts. To help prevent mould from growing, it is important to have your air ducts cleaned on a regular basis. This will remove the debris that mould needs to grow, and help keep your air quality high.
