When the temperature outside plunges, most Saskatoon homeowners close windows and rely on their furnaces 24/7. That means less fresh air, more recirculation, and a higher concentration of dust and allergens indoors. Maintaining clean filters and vents during winter protects both your health and your HVAC system’s efficiency.
Why Indoor Air Quality Declines in Winter
- Homes are sealed tight to retain heat.
- Continuous furnace operation recirculates dust and pollutants.
- Low humidity irritates skin and respiratory passages.
Health Canada notes that Canadians spend up to 90 percent of their time indoors during winter, making clean air a necessity, not a luxury.
The Role of Furnace Filters
- Trap airborne particles before they enter ducts.
- Keep blower motors and heat exchangers clean.
- Improve efficiency and extend equipment life.
Choose filters with a MERV rating between 8 and 12 for residential use. Change them every 1–3 months, especially if you have pets or suffer from allergies. Pro Service Mechanical offers scheduled filter replacement services as part of seasonal maintenance plans.
Vent Cleaning and Airflow Balance
- Remove lint, dust, and debris from supply and return vents.
- Ensure each room receives even heat.
- Prevent airflow restriction that strains the blower.
Blocked vents reduce furnace performance and can lead to overheating or premature part failure. Vacuum vents regularly and keep furniture clear of airflow paths.
Humidity and Ventilation Tips for Healthier Air
- Maintain indoor humidity between 30–40 percent.
- Use a humidifier attached to your furnace for steady moisture.
- Run bathroom and kitchen fans to remove moisture and odours.
Balanced humidity not only prevents dry skin and static but also reduces dust circulation. For homes using HRV (Heat Recovery Ventilator) systems, Pro Service Mechanical can adjust winter settings for optimal air exchange without major heat loss.
Signs Your Air Quality Needs Attention
- Frequent static shocks or dry throat.
- Dust buildup near vents.
- Unexplained allergy symptoms.
- Uneven heat or persistent odours.
If these occur, schedule a professional duct inspection — our technicians use high-efficiency vacuums to remove contaminants that regular cleaning can’t reach.
Healthy indoor air starts with clean filters, open vents, and balanced humidity. By maintaining these basics, your furnace will run smoother and your family will breathe easier all winter long.
Schedule a winter air-quality inspection with Pro Service Mechanical, Saskatoon’s trusted HVAC experts, and enjoy cleaner, safer air this heating season.
