No matter how well you take care of your air ducts, they’ll eventually end up getting dirty due to everyday usage. Nasties commonly pop up in air ducts, causing the ducts to work needlessly harder to produce clean air throughout the building. Not only will this make your energy bills higher, but it will also compromise how clean your air is and reduce the lifespan of your HVAC system. There are three nasties in particular you should keep an eye out for if your system isn’t working as well as it should.
All homes accumulate some level of dust, dirt, pet dander and other kinds of harmful contaminants that can build up inside air ducts. These contaminants may start to come out of your ducts when they’re blowing air into your building. If this is the case, you should inspect the vents around your building. If both the vent covers and the ductwork are covered in any type of Debris or particle, you should organise duct cleaning as soon as possible.
Heating and cooling systems can accumulate condensation, causing mould to grow inside your ductwork. Mould can spread very fast once it gets inside ductwork, triggering allergies and respiratory issues for your family or employees. Mould can go undetected for a long time, as many areas of your ductwork are hard to access properly which means it can go unnoticed. The most common tell-tale sign of a mould build-up in air ducts is when the air being produced has a musty odour to it.
Pests like rodents and insects can get inside air ducts, where they will build nests and leave droppings, both of which can contain harmful bacteria. These bacteria may contaminate the air being generated which is then spread throughout your building. Not only does this cause the air you breathe in to be full of bacteria, but it will also force the system to work harder, raising your power bills.
