FAQs
Why is indoor air quality (IAQ) such a concern for homeowners in La Follette?
La Follette’s lush Cumberland Mountain setting exposes homes to high outdoor pollen counts, forest fire particulates drifting from neighboring regions, and naturally humid summers that can foster mold growth inside. Many houses are also older and more tightly sealed after weather-proofing improvements, so airborne contaminants—dust, pet dander, cleaning fumes, and even radon seeping from the ground—can accumulate faster than they are vented out. Good IAQ protects respiratory health, reduces allergy and asthma symptoms, and helps your HVAC system run more efficiently year-round.
How often should I replace my HVAC air filter, and what rating should I choose?
In La Follette’s mixed-climate region, a standard 1-inch pleated filter should be checked monthly and replaced every 60–90 days. Households with pets, smokers, or allergy sufferers should change filters every 30–45 days. Look for a MERV (Minimum Efficiency Reporting Value) rating between 8 and 13: • MERV 8–10 captures everyday dust and pollen while maintaining low airflow resistance. • MERV 11–13 traps smaller particles such as smoke, mold spores, and some bacteria, ideal for allergy relief. Make sure your blower motor is rated for higher-MERV filters; otherwise, consult an HVAC professional before upgrading.
What ventilation solutions can I add to an existing home to improve air quality?
Several retrofit options work well in East Tennessee homes: 1. Energy Recovery Ventilators (ERVs) or Heat Recovery Ventilators (HRVs) exchange stale indoor air with fresh outdoor air while reclaiming up to 80 % of heating or cooling energy. 2. Dedicated mechanical exhaust fans in kitchens, baths, and laundry rooms remove moisture and odors at the source; look for fans rated 1 cfm per square foot of floor area. 3. A fresh-air intake tied to your HVAC return brings in filtered outside air on a controlled schedule. 4. Smart, variable-speed bathroom fans and whole-house ventilators can be set to run when indoor humidity or CO₂ rises above target levels.
Does high humidity affect IAQ, and what can I do about it during La Follette’s muggy summers?
Yes. Relative humidity above 60 % encourages mold, dust-mite growth, and musty odors. Your central air conditioner removes moisture while cooling, but it must be sized and maintained properly: • Schedule a spring tune-up so coils are clean, refrigerant charge is correct, and airflow is balanced. • Use a whole-house dehumidifier if indoor RH frequently exceeds 55 % or if your AC short-cycles because it is oversized. • Run bathroom and kitchen exhaust fans for at least 20 minutes after showers or cooking. • Seal crawlspaces and install vapor barriers to reduce moisture wicking into living areas.
How often should my ductwork be inspected or cleaned?
The National Air Duct Cleaners Association (NADCA) recommends an inspection every 2–3 years and cleaning every 5–8 years, or sooner if you notice: • Visible mold inside supply vents • Excessive dust blowing from registers after filter changes • Rodent or insect infestations • Recent renovation projects generating drywall or wood dust Proper cleaning includes brushing and vacuuming all trunk lines and branches, sanitizing when microbial growth is present, and resealing any gaps with mastic to prevent energy loss and contaminant infiltration.
Do UV lights and electronic air purifiers really help remove viruses, bacteria, and allergens?
When professionally installed and paired with good filtration, they add a strong second line of defense: • UV-C lamps mounted near the evaporator coil sterilize microbes on wet coil surfaces and in passing air. They can reduce airborne bacteria and mold by up to 99 % within 24 hours. • Photocatalytic oxidation (PCO) devices neutralize volatile organic compounds (VOCs) from paints, cleaners, and cooking odors. • Bipolar ionizers charge particles so they clump together and are trapped by the filter more easily. While no technology can guarantee 100 % pathogen removal, these systems lower overall contaminant levels and complement high-MERV filtration, routine maintenance, and adequate ventilation.
