When winter settles in, most of us spend a lot more time indoors and in South Carolina, even the milder cold months are enough to keep windows closed and heating systems humming. While that keeps things cozy, it also means indoor air gets recycled more often, allowing dust, allergens and other pollutants to build up quickly.
To stay ahead of winter air issues, start with a few simple steps. This can start with replacing your HVAC filters regularly, using a humidifier to ease dry indoor air or vacuuming around vents to keep airflow clear. Other great ideas are testing your carbon monoxide and smoke detectors and cracking a window on mild days to refresh stale air.
1. Check and Replace HVAC Filters
Your heating system works hard during the colder months, which means your air filters do too. Dirty or clogged filters can restrict airflow and recirculate dust and allergens throughout your home. It’s a good idea to check filters monthly and replace them at least every 60–90 days. For families with pets or allergy issues, upgrading to a high-efficiency filter can make a noticeable difference.
2. Balance Indoor Humidity
Winter air tends to be dry, and while South Carolina doesn’t experience extreme cold, indoor heating can still strip moisture from the air. If you’re noticing dry skin, scratchy throats or static shocks, it might be time to bring in a humidifier. Just be careful not to overdo it. Too much humidity can create ideal conditions for mold and mildew. Aim to keep indoor levels between 30% and 50%.
3. Keep Vents and Ducts Clean
Dust and debris can build up quickly in your HVAC vents, especially when air is circulating nonstop. Take a few minutes to vacuum around vents and registers, while also making sure furniture or curtains aren’t blocking airflow. If you notice uneven heating or dusty smells when the heat kicks on, it might be worth having your ductwork inspected and cleaned professionally.
4. Test for Carbon Monoxide and Fire Safety
Cold weather means heating systems are running more often, which makes safety checks especially important. Here are a few winter-specific precautions to keep your home safe:
- Make sure carbon monoxide detectors are installed on each floor and near sleeping areas
- Press the test button on both CO and smoke detectors to confirm they’re working
- Replace batteries if needed—winter is a common time for battery failures
- If your home uses gas heating, schedule a professional safety inspection
- Avoid using fuel-burning appliances indoors unless they’re properly vented
5. Watch for Stale or Stuffy Air
If your home starts to feel heavy, musty or just “off,” it could be a sign your indoor air isn’t circulating well. On milder days, cracking a window for just a few minutes can introduce a burst of fresh air. Kitchen and bathroom exhaust fans are also great tools to help move stale air out and keep humidity in check.
6. Consider Extra Solutions
If you’ve taken the basic steps and still struggle with air quality, additional solutions like portable air purifiers or whole-home air filtration systems might be worth considering. HVAC-compatible options like UV lights or air scrubbers can also target bacteria, mold spores and airborne pollutants.
