FAQs
Why is indoor air quality a particular concern for homes and businesses in Decherd, TN?
Decherd’s warm, humid summers and mild winters mean buildings are often sealed to keep conditioned air inside, which can trap pollutants such as pollen, mold spores, dust, and volatile organic compounds (VOCs). The surrounding rural areas also contribute seasonal allergens, while older housing stock may contain outdated HVAC systems that struggle to filter contaminants. Improving indoor air quality (IAQ) protects respiratory health, reduces allergy symptoms, and boosts overall comfort year-round.
What HVAC upgrades provide the biggest improvement in indoor air quality?
Several add-ons can dramatically enhance IAQ: 1) High-MERV or HEPA filtration captures fine particulates and allergens. 2) UV-C germicidal lamps installed in the air handler neutralize bacteria, viruses, and mold on coils. 3) Energy Recovery Ventilators (ERVs) bring in fresh outdoor air while minimizing energy loss and balancing humidity. 4) Whole-home dehumidifiers keep relative humidity between 40-50 %, discouraging mold growth. 5) Advanced air purification systems such as bipolar ionization or photocatalytic oxidation break down VOCs and odors.
How often should I replace or clean my HVAC air filters in the Decherd area?
Standard 1-inch pleated filters should be checked monthly and replaced every 60–90 days. During peak pollen seasons (spring and early fall), monthly replacement is advisable. Thicker 4- to 5-inch media filters can last 6–12 months but still warrant inspections every 90 days. Homes with pets, smokers, or residents with allergies should err on the shorter end of these ranges. Regular filter changes keep airflow unobstructed, protect equipment, and maintain healthy air.
What is the difference between ventilation and air purification?
Ventilation refers to the intentional exchange of indoor and outdoor air to dilute indoor pollutants and control humidity. It’s achieved through mechanical systems like ERVs/HRVs or by strategic use of exhaust fans. Air purification, on the other hand, is the process of removing contaminants already inside the home—using filters, UV lights, ionization, or activated carbon. Effective IAQ strategies typically combine both: ventilation to bring in fresh air and purification to clean the recirculated air.
Can high humidity really impact indoor air quality, and how can I control it?
Yes. Relative humidity above 60 % supports mold, mildew, and dust-mite growth, all of which degrade IAQ and can trigger allergies or asthma. High moisture also makes the air feel warmer, causing your AC to run longer. Solutions include whole-home dehumidifiers integrated into your HVAC system, properly sized air conditioners with variable-speed blowers, sealing duct leaks to prevent moisture intrusion, and using bathroom and kitchen exhaust fans during high-moisture activities.
Do smart thermostats and air-quality monitors actually help?
Absolutely. Many smart thermostats include humidity sensors and can be paired with IAQ modules that measure particulates, VOCs, and CO₂ levels. They provide real-time data via mobile apps, send alerts when air quality drops, and can automatically activate ventilation or purification equipment. This proactive approach allows Decherd residents to respond quickly to pollution spikes—such as high pollen days or indoor activities like cooking and cleaning—before they affect comfort or health.
