How Canada’s Wildfires Can Impact Your Indoor Air Quality

Wildfires are an unfortunate reality for many parts of the world as it becomes harder to control and mitigate out-of-control blazes. With wildfires becoming an increasingly pressing issue that impacts all people, regardless of borders, it’s crucial to know how to keep the air you breathe free from harmful contaminants.?

One of the issues that homeowners and businesses face during a wildfire is the impact it can have on their HVAC unit. Smoke particles can cause damage to the HVAC system, which can lead to expensive repairs or even replacement. When smoke particles enter the HVAC system, they can clog air filters, evaporator coils, and blower motors. Over time, this can reduce the efficiency of the HVAC system, leading to higher energy bills and decreased air quality.

In addition to damaging the HVAC system, smoke from wildfires can also negatively impact indoor air quality. According to a 2015 paper from Jawaharlal Nehru University in New Delhi, “Apart from smoke comprising of unburnt carbon particle, the emission from wildfire [sic] comprises carbon monoxide, ash participles, methyl chloride, methyl bromide, polynuclear aromatic hydrocarbons, aldehydes, VOC gases.” Smoke particles can make their way indoors through open windows and doors, as well as through cracks in the walls and foundation. This can lead to respiratory issues and other health problems for occupants.

To protect your HVAC system (and indoor air quality) during a wildfire, it's important to follow these steps:

? Keep all windows and doors closed to prevent smoke from entering the home

? Turn off the HVAC system to prevent smoke from circulating through the ductwork

? Cover outdoor intake vents with a filter, such as a HEPA filter, to prevent smoke particles from entering the HVAC system

? After the wildfire has passed, have your HVAC system inspected and serviced by a professional to ensure that it is functioning properly

Smoke from wildfires can have a significant impact on your HVAC system and indoor air quality. By taking steps to protect your HVAC system during a wildfire and having it serviced after the event, you can help to ensure that your space is protected for years to come. Don't wait until it's too late – take action today to protect your HVAC system and the air you breathe.?
