As winter sets in across Canada, the cold air outside prompts us to turn up the heat indoors. While this creates a cozy atmosphere, it can also lead to a decrease in indoor air quality (IAQ). Dry air, dust, allergens, and inadequate ventilation are just a few of the challenges Canadians face during the heating season. Fortunately, maintaining clean air in your home during winter is not only possible but essential for health and comfort.

At Airtek, we are dedicated to providing high-quality heating and cooling equipment to HVAC professionals across Canada. In this blog, we'll explore why clean indoor air is crucial during winter and share practical HVAC maintenance tips to help ensure your indoor environment stays fresh, healthy, and comfortable all season long.

Why Indoor Air Quality Matters in Winter

1. Dry Air and Health

The dry air in winter can significantly reduce humidity levels indoors. Low humidity can irritate your respiratory system, causing dry skin, itchy eyes, and discomfort in your throat and nose. In some cases, it can also aggravate existing health issues such as asthma or allergies. Maintaining optimal humidity levels helps reduce these issues and keeps the air more comfortable.

2. Dust and Allergens

Heating systems like furnaces or heat pumps can stir up dust, pollen, pet dander, and other allergens that have settled over the summer. As your HVAC system runs to maintain warmth, these particles are often redistributed throughout your home, which can worsen indoor air quality. Regular maintenance and cleaning can help minimize this problem and ensure that your HVAC system is working efficiently.

3. Indoor Pollutants

Winter is the time when we keep windows and doors closed to retain heat, which can trap indoor pollutants such as volatile organic compounds (VOCs), carbon monoxide, and smoke. Inadequate ventilation can exacerbate these issues. Poor indoor air quality has been linked to fatigue, headaches, eye irritation, and even more serious health problems over time.

HVAC Maintenance Tips for Cleaner Air

Maintaining clean air in your home during the heating season starts with ensuring your HVAC system is working at its best. Here are some HVAC maintenance tips to help keep the air in your home fresh and healthy:

1. Change Your Air Filters Regularly

Air filters play a critical role in trapping dust, dirt, and allergens before they circulate through your home. Over time, these filters can become clogged, reducing their efficiency and allowing particles to pass through. During the winter months, it’s recommended to check and replace your air filters every 1–3 months, depending on the type of filter and the level of dust in your home.

2. Clean Your Air Ducts

If your home has forced air heating, dust and debris can accumulate in your air ducts, which then circulate throughout your home each time the system turns on. Cleaning your ducts every few years can help ensure that the air circulating through your home is clean. Professional duct cleaning services can remove built-up dust, mold, and other pollutants, improving both your air quality and system efficiency.

3. Humidify Your Home

As mentioned earlier, the dry air of winter can reduce the humidity in your home, causing discomfort and even contributing to respiratory issues. Consider investing in a whole-house humidifier integrated with your HVAC system, or use portable units to maintain the right humidity levels. Ideal indoor humidity is typically between 30% and 50%, which helps keep your airways moist and minimizes the spread of respiratory viruses.

4. Ensure Proper Ventilation

Proper ventilation is essential to maintain clean indoor air, especially in tightly sealed homes. Without fresh outdoor air to circulate, pollutants can accumulate, creating an unhealthy environment. Ensure that your HVAC system is equipped with a heat recovery ventilator (HRV) or an energy recovery ventilator (ERV) to bring in fresh air while conserving energy. These systems help remove stale air from your home and replace it with fresh, filtered air, all while maintaining the warmth indoors.

5. Schedule Regular HVAC Maintenance

To keep your HVAC system running efficiently, it’s crucial to schedule regular maintenance with a licensed HVAC technician. This typically involves cleaning and inspecting your heating equipment, checking for any potential issues, and ensuring everything is running smoothly. A well-maintained HVAC system not only ensures optimal performance but also contributes to cleaner air by reducing the risk of mold, dust, and allergens building up inside your equipment.

6. Check for Carbon Monoxide Leaks

As you rely on your heating system more during the winter, it’s important to check for carbon monoxide (CO) leaks, which can be a dangerous pollutant. Install a carbon monoxide detector near your furnace, and schedule a professional inspection of your heating system to ensure it is functioning properly. If you use a fireplace or gas heater, ensure they are vented correctly to prevent CO buildup.

7. Use an Air Purifier

For an extra layer of protection, consider investing in a high-efficiency particulate air (HEPA) air purifier for rooms where air quality is a concern. HEPA filters can trap very small particles, such as allergens, dust, and pet dander. Some air purifiers are also equipped with activated carbon filters that can help remove odors and VOCs, ensuring a healthier indoor environment.
