Experts say wildfire smoke may be in your home’s ducts.

Following the worst summer on record for forest fires, homeowners are looking for solutions to protect themselves from declining air quality–a trend that looks like it is here to stay. Strong winds have allowed the smoke to travel hundreds of miles, affecting air quality in Calgary. Since May, there have been several weeks where the air quality index was rated high risk (rated 7-10). Many days, it was hard to see downtown office towers through the smoke.

Smoke particles have likely entered your ducts.

While you no doubt kept your windows and doors closed when the smoke was at its worst, it most likely entered your home, according to Ami Li in a CBC interview. LI is an air quality expert at Waterloo University.“(Smoke particles can) infiltrate your room through all the cracks and leakages in the building enclosure.”Li added that these particles can be carried through your ventilation systems, where they can accumulate.”It’s interesting because typically we need the fresh outdoor air to address indoor pollutants. But in this case, we do not want it if it’s not filtered.”

What should homeowners do?

2. Change your Furnace Filter

After a year of intense wildfire smoke, changing your furnace filter is a must. If you use a high-quality furnace filter, it has likely removed the majority of smoke particles that may have entered your home. However, particulates such as dust, allergens, pet hair/dander and cigarette/wildfire smoke can easily get trapped in the ducts and later circulate into your living areas through the vents.

3. Clean Your Ducts and Furnace

Getting your ducts cleaned is also highly recommended. Duct cleaning technicians use air-pressured wands to dislodge any materials or pollutants in your HVAC system and furnace(including smoke particles). A high-powered vacuum hose is attached to your furnace to break everything up. Companies such as Advanpro provide the option of a deeper clean. Also, once your duct cleaning is complete, Advanpro will change the filter as part of the service.

Breathe easier.

Those with allergies or breathing issues are most affected by smoke particles, dust and allergens. A duct and furnace cleaning will help improve the home’s quality and make breathing easier.

Speaking of fire…

Did you know that the lint from your dryer machine is extremely flammable? In rare cases, the heat from a dryer can cause built-up lint in the dryer or dryer vent to ignite. While you’re getting your ducts cleaned, it is suggested that you have the technician vacuum out your dryer vents. At Advanpro, dryer vent cleaning is available as an optional service ($59.95 ground floor,$129.95 second floor) or as part of our UltimateTotal Care Package.
