FAQs
What is HEPA filtration and how does it improve indoor air quality in Dandridge?
HEPA (High-Efficiency Particulate Air) filtration uses a dense, pleated media that captures at least 99.97 % of airborne particles down to 0.3 microns—smaller than most pollen, mold spores, pet dander, and even some bacteria. In Dandridge, where spring and fall pollen counts are high and older homes may harbor dust from crawlspaces, a HEPA filter prevents these pollutants from circulating through your heating and air conditioning system, giving allergy and asthma sufferers noticeable relief and helping every occupant breathe cleaner, healthier air.
How often should HEPA filters be replaced or cleaned in my HVAC system?
Because HEPA media traps so many fine particles, it loads up faster than standard HVAC filters. For most residences in Dandridge, replacement every 12–18 months is typical. However, homes with pets, smokers, recent construction work, or residents with respiratory issues may need service every 6–12 months. Always follow the manufacturer’s instructions and schedule a professional inspection during your bi-annual HVAC tune-ups to verify airflow and pressure remain within specifications.
Can a HEPA filter be added to my existing heating and air conditioning system?
Yes—most modern forced-air systems can be upgraded, but it must be done correctly. A true HEPA unit is usually installed in a bypass configuration: a small portion of return air is diverted through the HEPA cabinet and then mixed back into the supply duct. This prevents the high resistance of HEPA media from over-straining the blower. Our Dandridge technicians evaluate your equipment’s static-pressure limits, duct size, and air-flow needs to design a retrofit that meets ASHRAE standards without voiding warranties or reducing comfort.
How does Dandridge’s seasonal pollen and humidity affect my ventilation needs?
East Tennessee’s humid summers and tree-pollen springs mean homes need both filtration and controlled ventilation. Excess humidity encourages mold growth in ductwork and crawlspaces, while opening windows during peak pollen season brings allergens indoors. A balanced mechanical ventilation system with MERV-13 pre-filters and an optional energy-recovery ventilator (ERV) supplies fresh air year-round while maintaining comfortable humidity levels and ensuring the HEPA filter handles only the cleanest possible airstream.
Will installing a HEPA filtration system increase my energy bills?
When properly sized and installed, a bypass HEPA unit adds minimal resistance to your HVAC airflow, so the impact on energy use is small—typically less than the cost of running a 60-watt light bulb continuously. Any modest increase is often offset by improved system cleanliness: coils stay dust-free, allowing your heat pump or air conditioner to operate at peak efficiency. Many homeowners also find they run their equipment less frequently because filtered air feels fresher and they can keep the thermostat a degree or two higher in summer or lower in winter.
How do I know if my home would benefit from a whole-house HEPA filtration and ventilation upgrade?
Signs include persistent allergy or asthma symptoms indoors, visible dust shortly after cleaning, lingering odors, or a musty smell in closets and crawlspaces. Homes built before 2000, houses near busy roads or agricultural fields, and households with pets, smokers, or wood-burning stoves see the greatest benefit. Our team offers on-site air-quality assessments in Dandridge: we measure particulate counts, humidity, and carbon dioxide levels, then provide a written report and proposal outlining the best combination of HEPA filtration, ventilation, and humidity control for your budget and lifestyle.
