Indoor Air Quality Services
🌬️
Air Purifiers
Whole-home air purifiers installed in the HVAC system treat air as it circulates through the house. More effective than portable units at reducing airborne particles, allergens, and odors throughout the entire home.
🔍
Filtration Upgrades
Upgrading from a standard 1-inch filter to a higher-MERV media filter or electronic air cleaner significantly improves particle removal without the cost of a full air purifier system.
💧
Whole-Home Humidifiers
Georgia winters are drier than most people expect. A whole-home humidifier installed on the HVAC system maintains healthy indoor humidity levels automatically — reducing static electricity, dry skin, and the survival rate of airborne viruses.
☀️
UV Light Systems
UV germicidal lights installed in the air handler kill mold, bacteria, and viruses on the evaporator coil and in the airstream. Particularly effective in Georgia’s humid climate where mold growth on coils is common.
Indoor Air Quality in Georgia: What Makes It Different
The north Atlanta area presents some specific indoor air quality challenges. Georgia’s humid summers encourage mold and mildew growth — particularly on HVAC evaporator coils, which stay cold and damp and provide an ideal growing environment if not treated. Pollen counts in the Atlanta metro are among the highest in the country, with tree pollen in late winter and spring, grass pollen in summer, and weed pollen in fall. Homes that are tightly insulated for energy efficiency — which most newer construction in Roswell and Alpharetta is — trap these particles inside effectively. Good filtration and air treatment makes a measurable difference in homes with allergy sufferers.
Humidity control is also important in both directions. Georgia summers bring humidity levels that can make the indoor environment uncomfortable and encourage mold growth even with air conditioning running. Georgia winters, while mild, drop indoor humidity enough to cause dry air problems. A properly functioning HVAC system with appropriate humidity controls keeps the indoor environment in the 35–55% relative humidity range year-round — the range where people are most comfortable and the least hospitable to mold and airborne pathogens.
Frequently Asked Questions
My home feels stuffy even with the AC running. What could cause that?
A few possibilities: the system may be oversized and short cycling, which means it cools quickly but doesn’t run long enough to adequately dehumidify the air. The filter may be dirty enough to restrict airflow. There may be duct leakage pulling unconditioned air from a crawl space or attic. Or the home may simply benefit from a dedicated ventilation or dehumidification solution. We can assess and tell you which it is.
Is a whole-home air purifier worth it compared to a portable unit?
For whole-house coverage, yes. Portable units treat one room at a time and require regular filter replacements. A whole-home system treats all air circulating through the HVAC system, covers the entire house, and is generally lower maintenance over time. The upfront cost is higher but the long-term value is better for most households.
Does a UV light system actually work?
For mold control on the evaporator coil, yes — UV germicidal lights are highly effective and are widely used in commercial HVAC applications for exactly this purpose. For airborne pathogen reduction, effectiveness depends on air speed through the system. We’ll tell you honestly what a UV system will and won’t do for your specific situation.
How do I get started?
Call us at (770) 239-6628 and describe what you’re experiencing — stuffiness, allergy symptoms, mold odor, dry air in winter, or whatever the specific concern is. We’ll schedule a visit, assess your current system and home, and recommend solutions that are actually appropriate rather than just selling you the most expensive option available.
