At Complete Air & Heat, Inc., we know winter on the Space Coast doesn’t always mean freezing temperatures. But those occasional cool snaps change how homes “breathe.” Windows stay shut, fresh-air exchange drops, and humidity can linger indoors. That combination can allow mold spores, dust, and other allergens to build up and circulate. Below are five practical ways to reduce mold and allergens with HVAC and IAQ upgrades that pair well with seasonal service.
1. Book a seasonal HVAC tune-up
Maintenance is the foundation of healthier indoor air. During a winter tune-up, our technicians inspect the system, clean critical components, verify safe operation, and check condensate drainage and airflow. We also look for signs of excess moisture around coils and drain lines, because small drainage problems can become big IAQ problems. Addressing minor issues early helps prevent microbial growth and keeps your system running efficiently.
2. Upgrade your filtration and replace it on schedule
Your air filter is your first line of defense against allergens. Standard filters catch larger particles, but higher-efficiency options capture more of what triggers sneezing and irritation, including fine dust and dander. We can recommend the right filter rating for your system so you improve air cleanliness without restricting airflow. Just as important: change filters consistently, especially during periods when your system runs more often.
3. Balance humidity with IAQ add-ons
Mold loves moisture. Even in winter, indoor humidity can remain high—especially when the home is closed up after a rainy day or a cool front. A whole-home dehumidifier helps maintain healthier moisture levels and supports consistent comfort. If a dehumidifier isn’t the best fit, we can evaluate other humidity-control options that integrate with your HVAC equipment and promote better air balance.
4. Improve airflow and keep air where it belongs
When airflow is uneven, allergens can settle in certain rooms and get stirred up repeatedly. Simple adjustments, such as ensuring nothing is blocking vents, can improve airflow. Sealing duct leaks is also a big win—leaks can pull dusty air into the system and send it through your vents, undermining your IAQ goals and raising energy use.
5. Add targeted air-cleaning technology
For an extra layer of protection, consider IAQ upgrades such as whole-home air purifiers or UV systems. These solutions work alongside your HVAC system to reduce airborne particles and help address microbial growth inside the equipment. They’re especially helpful during winter months when you’re spending more time indoors and relying on mechanical circulation instead of open windows.
