It’s important to keep your air ducts clean to keep them working and prevent spreading dust throughout a home or building. HVAC systems can distribute allergens and germs quite easily, more so if the system is connected to every room. There are some health risks that can occur when air ducts haven’t been cleaned in a while, including:


Dirty Air Duct Health Risks



Dusty surroundings can trigger asthma attacks, leading to chest pain, shortness of breath, coughing, or wheezing. Serious cases can require hospitalization, so take the time to clean ducts and avoid potentially serious medical issues.



Dust, pollen, or mould in air ducts can trigger allergic reactions or prolong them. Some common symptoms include fatigue, runny nose, and sneezing. Suffering from allergies at work can negatively affect focus and productivity. Allergies in the home impede our ability to rest.

Spread of disease

Dirty air ducts can become breeding grounds for pests like rodents and insects. Any germs they carry can be dispersed throughout the entire system. Dander from furry pests can also trigger allergies. Rodents also carry parasites (like fleas) that present other health risks to everyone in the building.



The insulation in unclean ducts breaks down over time. If asbestos degenerates, it is then carried through the air ducts. When inhaled, asbestos exposure can cause serious illness. Clean and maintain your HVAC system regularly to avoid potential health scares.

Dry skin

Mouldy ducts can cause medical conditions not limited to respiratory issues. The particles given off can cause rashes and hives, and possibly eczema. Dirty HVAC systems spread dust, inflaming skin after prolonged exposure.


Respiratory tract infections 

Even people not prone to allergies or asthma can suffer from breathing in too much dust. This can lead to coughing, sore throat, nasal congestion, and fever.

Having a dusty HVAC system puts everyone in a building at risk for respiratory problems. Too much dust in the environment also encourages skin allergies. Keep air ducts clean to avoid these health issues and the resulting impact they have on your daily activities and life.
