FAQs
Why is controlling airborne pathogens important in Bluff City’s climate?
Bluff City experiences hot, humid summers and generally mild winters, conditions that encourage mold, bacteria, and viruses to thrive indoors if air circulation is poor. Because most homes and businesses run their HVAC systems nearly year-round, microorganisms can build up in ductwork and recirculate through occupied spaces. Proper control of airborne pathogens helps reduce allergy symptoms, respiratory infections, and odors while protecting vulnerable occupants such as children, older adults, and people with asthma or compromised immune systems.
What HVAC upgrades can help reduce airborne pathogens in my home or business?
Several add-ons are highly effective: (1) High-efficiency pleated or HEPA filters capture tiny particles down to 0.3 microns. (2) UV-C germicidal lamps installed in the air handler or coil chamber inactivate viruses, bacteria, and mold spores as air passes by. (3) Bipolar ionization devices release charged ions that cluster and drop airborne contaminants out of the air stream. (4) Dedicated energy-recovery ventilators (ERVs) bring in fresh outdoor air without a large energy penalty. A qualified HVAC technician can evaluate your existing system’s airflow and electrical capacity to recommend the best combination of upgrades.
How often should I change or clean my air filters to maintain healthy indoor air quality?
For standard 1-inch disposable filters, we recommend replacement every 30–60 days during heavy HVAC use. High-MERV or HEPA media may last 3–6 months but must be inspected monthly for dust loading. In households with pets, smokers, or allergy sufferers, more frequent changes—every 30 days—better control dander and fine particles. Washable electrostatic filters should be rinsed at least once a month and fully dried before reinstallation to prevent mold growth.
Does UV-C light sterilization in HVAC systems really work?
Yes—multiple peer-reviewed studies show that UV-C irradiation (wavelength 253.7 nm) can inactivate up to 99.9 % of airborne viruses, bacteria, and mold on contact when sized and installed correctly. Lamps placed downstream of the cooling coil keep biofilms from forming, improving both air quality and system efficiency. Annual lamp replacement and periodic glass sleeve cleaning are required to maintain output, and UV angles must be engineered to avoid damaging plastic or wiring inside the air handler.
Can improved ventilation lower the risk of COVID-19 and other respiratory illnesses indoors?
Absolutely. Increasing the amount of outdoor air dilutes the concentration of infectious aerosols, lowering the likelihood that occupants will inhale a high enough dose to become sick. The CDC and ASHRAE recommend boosting air changes per hour (ACH) to at least 6 in shared spaces. Opening windows can help in mild weather, but ERVs or dedicated outdoor-air systems supply fresh air year-round without undermining temperature or humidity control.
What professional indoor air-quality services do you offer in Bluff City?
