Winter Indoor Air Quality Tips for Missouri Homes

When winter arrives in Mid-Missouri, we close our windows, turn up the heat, and spend more time indoors — which means indoor air quality (IAQ) becomes more important than ever.

At PolarCore Heating and Air Conditioning, we help homeowners across Columbia, Jefferson City, Fulton, and beyond breathe easier all winter long. Here are our top expert tips to improve IAQ in your home during the colder months.

1. Combat Dry Air with a Whole-Home Humidifier

Heaters dry out indoor air, which can lead to sore throats, dry skin, and even nosebleeds. Installing a humidifier helps maintain ideal humidity levels between 30–50% — keeping you healthier and your wooden furniture protected.

2. Replace Your HVAC Filter Regularly

Your HVAC filter plays a major role in trapping dust, dander, and allergens. In winter, when your system runs more often, we recommend changing filters every 1–2 months for optimal airflow and filtration.

3. Consider Installing an Air Purifier

Air purifiers help capture bacteria, viruses, and fine particles that regular filters miss. UV and HEPA systems work with your HVAC system to sanitize the air continuously.

4. Schedule Duct Cleaning if You Haven’t in Years

If it’s been 5+ years since your last duct cleaning, dust and debris may be circulating through your vents every time the furnace kicks on. Our professional duct cleaning service can restore clean airflow and reduce allergens.

5. Don’t Block Vents or Registers

Keep furniture, rugs, or curtains from covering vents and returns. Blocked airflow reduces HVAC efficiency and can trap stale air in certain parts of your home.

6. Have Your System Professionally Maintained

Dirty coils, filters, or malfunctioning fans can make your air dirtier without you realizing it. A seasonal HVAC maintenance visit ensures your system is operating safely and efficiently through winter.
