FAQs
Why is indoor air quality such a concern in Erwin, TN, and how does our climate affect it?
Erwin’s warm, humid summers and cool winters mean our homes are often closed up for long stretches while HVAC systems run. This limits the natural exchange of outdoor and indoor air, allowing dust, pet dander, pollen, mold spores, and chemical vapors to build up. Because the region sits in a valley, outdoor pollutants can linger and be pulled indoors. Poor indoor air quality (IAQ) can aggravate allergies, asthma, and other respiratory issues. Addressing IAQ is therefore as essential as keeping your home comfortable year-round.
Which air filters or purification products work best for homes in the Erwin area?
Standard 1-inch fiberglass filters only capture about 10% of airborne particles. Upgrading to a pleated MERV-8 or MERV-11 filter is an affordable first step for most homes. If family members have allergies, a MERV-13 media cabinet or HEPA bypass filter can trap up to 99.97% of microscopic particles. For odors, smoke, and chemical vapors, we recommend adding an activated-carbon filter or an in-duct UV-light/photocatalytic purifier. A certified HVAC professional can verify that your system has enough blower capacity to handle the added airflow resistance of higher-grade filters.
How often should I change my filters and schedule IAQ-related maintenance?
• 1-inch pleated filters: every 1–3 months, depending on pets, smoking, and construction dust. • 4- to 5-inch media filters: every 6–12 months. • HEPA or electronic air cleaners: inspect quarterly; replace media or wash cells every 6–12 months. • UV lamps: replace bulbs annually to maintain germicidal strength. • Whole-home humidifiers/dehumidifiers and ERVs/HRVs: clean drain pans, check cores, and sanitize components during your spring and fall HVAC tune-ups. Regular maintenance keeps airflow optimal and prevents microbial growth inside the equipment.
What advantages does a whole-home ventilator, ERV, or HRV provide over simply cracking a window?
Opening windows can introduce fresh air, but it also lets in humidity, pollen, and street noise and wastes conditioned air. Energy-Recovery Ventilators (ERVs) and Heat-Recovery Ventilators (HRVs) mechanically exchange stale indoor air with filtered outdoor air while reclaiming up to 80% of the heating or cooling energy. The result is balanced, continuous ventilation without a big utility-bill penalty. ERVs are preferred in Erwin’s humid climate because they transfer moisture as well as heat, helping keep indoor humidity in check. This controlled ventilation reduces odors, carbon dioxide buildup, and off-gassing from household products.
How does humidity control improve comfort and prevent mold in northeast Tennessee?
Ideal indoor relative humidity (RH) ranges from 30–50%. In summer, Erwin’s outdoor RH often exceeds 70%, making indoor air feel sticky and encouraging mold growth. A whole-home dehumidifier integrated with your HVAC system can pull out 8–16 gallons of water per day, lowering RH and allowing you to raise the thermostat a few degrees without sacrificing comfort. In winter, RH can plunge below 25%, drying out skin, wood furnishings, and musical instruments. A central humidifier adds gentle moisture to protect health and valuables. Keeping RH balanced also prevents condensation on windows, which can lead to wood rot and structural damage.
What signs suggest I should schedule professional IAQ testing or duct cleaning?
• Persistent musty or “dirty sock” odors when the HVAC runs. • Visible dust on vents only days after cleaning or dark buildup around supply grills. • Family members experiencing unexplained allergies or respiratory problems only while at home. • Rooms that feel stuffy, clammy, or have uneven temperatures. • Water damage, leaky roofs, or past flooding that may have introduced mold. • Evidence of pests or debris inside ductwork. An IAQ inspection can include particulate counts, humidity readings, carbon monoxide testing, and mold or VOC sampling. If contaminants are found, targeted solutions—such as duct cleaning, sealing, filtration upgrades, or mold remediation—can restore clean, healthy air.
