How to Manage Indoor Air Quality This Fall: Tips from Air-Tech Comfort Solutions
As fall settles into Woodruff, SC, your home’s indoor air quality (IAQ) becomes especially important. Cooler weather means more time spent indoors, closed windows, and sometimes more dust, allergens, and moisture issues. At Air-Tech Comfort Solutions, we want to help you breathe easier and keep your HVAC system running cleanly and efficiently through the season. Here’s what you should focus on this fall:
1. Change or upgrade your filters more often
Even though fall is milder than summer or winter, your HVAC system still runs to balance heating and cooling swings. Use high-quality pleated or HEPA-rated filters (as allowed by your system) and check them monthly. A clogged filter not only degrades your indoor air quality but forces your system to work harder.
2. Leverage your HVAC system’s fresh-air and ventilation settings
If your system allows, run the fan on the “on” position periodically to circulate fresh air and filter continuously. Also, if you have an energy recovery ventilator (ERV) or a whole-house ventilation system, fall is a great time to use it—bringing in fresh outdoor air while moderating temperature and humidity.
3. Monitor humidity — and consider a whole-house dehumidifier or humidifier
Relative humidity can still be high in the early fall, increasing mold or mildew risk. As it turns cooler, indoor air may become excessively dry. Maintain a relative humidity between 35–50% to prevent condensation, wood warping, or respiratory irritation. If your system supports it, installing or activating a humidifier or dehumidifier can make a big difference in comfort and air quality.
4. Seal gaps, ducts, and leaks now before winter
With windows shut and the HVAC system doing heavier work, any cracks or leaks in your ductwork will let contaminants in and conditioned air out. Inspect visible ducts (attics, crawl spaces), seal with mastic or foil tape, and check areas around plumbing, wiring, attic hatches, and exterior wall penetrations.
5. Clean accessory components: coils, drain pans, and vents
Dust, pollen, and debris have had months to accumulate. Fall is a smart time to have your technician inspect and clean your indoor evaporator coils, condensate drain pan, and vent registers. These areas, when clogged or dirty, contribute heavily to poor indoor air and can foster mold in damp climates.
6. Ask us about air purification and UV light systems
UV germicidal lights, high-efficiency air purifiers, and advanced filtration systems can reduce bacteria, viruses, allergens, and volatile organic compounds (VOCs). As you shift away from open windows, these systems help maintain good air health inside your home.
