Home renovations can kick up dust, debris, and harmful contaminants, which can easily spread through your HVAC system if not properly managed. Here’s how to protect your indoor air quality and HVAC system during renovations.
1. How Renovations Affect Indoor Air Quality
✔ Dust from drywall, wood, and plaster can clog HVAC filters and reduce efficiency.
✔ Paints, adhesives, and varnishes release VOCs (volatile organic compounds), affecting air quality (Source, Health Canada).
✔ Mold and asbestos risks – Older homes may have hidden mold or asbestos, which can become airborne during demolition (Source, Health Canada). It is always advised to get your home tested if you have any doubts about asbestos.
2. Steps to Protect Your HVAC System During Renovations
✔ Turn off your HVAC system – Running the system while renovating pulls dust and debris into the ductwork.
✔ Seal off vents and registers – Covering air vents with plastic sheeting prevents contaminants from circulating.
✔ Use temporary air filtration – FortisBC recommends using a portable HEPA air purifier to remove airborne particles.
✔ Work in well-ventilated areas – Keep windows open and use exhaust fans to reduce indoor pollutant buildup.
✔ Change air filters frequently – Natural Resources of Canada suggests replacing filters before and after renovations to prevent long-term HVAC damage.
3. When to Schedule an HVAC Inspection Post-Renovation
✔ If dust buildup is visible in vents or registers.
✔ If your home smells like paint fumes or chemicals after renovations.
✔ If airflow seems reduced, indicating clogged ducts or filters.
✔ If household allergies worsen, suggesting airborne contaminants are present.
