FAQs
What are “hidden pollutants” in my Tellico Plains home, and where do they come from?
Hidden pollutants are microscopic or hard-to-see contaminants such as mold spores, pollen, pet dander, dust mites, volatile organic compounds (VOCs), and combustion by-products. They enter your living space through open doors and windows, cooking, cleaning chemicals, building materials, and even from the soil beneath your home. Because Tellico Plains sits in a wooded, humid environment, outdoor allergens and moisture can amplify these indoor pollutants if ventilation is inadequate.
How can poor ventilation impact my family’s health and comfort?
Insufficient ventilation lets pollutants accumulate to levels that can trigger allergies, asthma, eye and throat irritation, headaches, and chronic respiratory issues. Stale, humid air can also promote mold growth, leading to musty odors and structural damage. Proper air exchange dilutes contaminants, stabilizes humidity, and keeps temperatures consistent, improving overall comfort and well-being.
What solutions do you offer to reduce hidden pollutants and improve indoor air quality (IAQ)?
We provide a complete IAQ toolkit: high-MERV or HEPA filtration upgrades, sealed and insulated ductwork, balanced mechanical ventilation systems (energy-recovery and heat-recovery ventilators), UV-C germicidal lights, whole-home dehumidifiers, and air purification systems that neutralize VOCs and odors. Our technicians begin with an on-site evaluation and air-quality testing to tailor a solution that suits Tellico Plains’ climate and your home’s specific needs.
How often should I replace filters and schedule duct or coil cleanings?
In our pollen-rich region, 1-inch pleated filters should be replaced every 1–3 months, while 4-inch media cartridges last about 6–9 months. If you have pets, allergies, or run the system constantly, shorten those intervals. We recommend professional duct inspections every 3–5 years and coil cleanings every 2–3 years, or sooner if you notice dust buildup, reduced airflow, or persistent odors.
Does Tellico Plains’ humidity make hidden pollutants worse?
Yes. High summertime humidity feeds dust mites and mold, while cool, damp winters can cause condensation inside walls and crawl spaces. Maintaining indoor relative humidity between 40–55 % with whole-home dehumidifiers or variable-speed HVAC systems keeps moisture-loving pollutants in check, protects wood furnishings, and reduces that sticky or clammy feeling indoors.
Are whole-home air purifiers and UV lights energy-efficient, and will they raise my utility bills?
Modern air purification units and UV germicidal lights use low-wattage ballasts—often comparable to a standard light bulb—so their energy draw is minimal. In many cases, cleaner coils and improved airflow actually lower overall HVAC energy consumption. We size and place these devices to maximize effectiveness while keeping operating costs negligible, then verify performance during routine maintenance visits.
