FAQs
What is an energy-recovery ventilator (ERV) and how does it work?
An ERV is a mechanical ventilation system that exchanges stale indoor air with fresh outdoor air while transferring heat and moisture between the two airstreams. In winter, it captures heat from outgoing air and pre-warms incoming air; in summer, it expels heat and humidity from incoming air to keep the home cooler and drier. The result is continuous ventilation with minimal energy loss.
Why is an ERV especially valuable in Vonore’s humid climate?
Vonore experiences warm, humid summers and cool, damp winters. Without balanced ventilation, excess moisture can lead to mold, allergens, and musty odors. An ERV not only supplies fresh air but also controls humidity by transferring moisture, helping keep indoor relative humidity in the ideal 40–60 % range year-round. This reduces mold growth, protects building materials, and enhances comfort.
How does an ERV improve indoor air quality compared with bathroom or kitchen exhaust fans alone?
Standard exhaust fans simply push air out, creating negative pressure that can draw unfiltered outdoor air, dust, and pollutants through cracks. An ERV provides balanced airflow—exhausting stale air while simultaneously supplying filtered, tempered fresh air. Most ERVs include MERV-rated filters that capture pollen, dust, and other particulates before the air enters your HVAC ducts, giving you cleaner, healthier indoor air throughout the entire home.
Will installing an ERV lower my heating and cooling bills?
Yes. Because up to 90 % of the heat (or cooling) energy in exhausted air is recovered and transferred to the incoming air, your HVAC system works less to reach the set temperature. Homeowners in the Vonore area typically see 10-25 % savings on ventilation-related energy costs compared to mechanical ventilation without heat recovery, especially in high-humidity months when dehumidification loads are high.
How loud are ERV systems and where are they installed in a typical Vonore home?
Modern ERVs are designed for quiet operation, usually in the 1.0–2.0 sone range—about as loud as a quiet refrigerator. Units are commonly installed in attics, mechanical closets, or conditioned crawl spaces and connected to dedicated ductwork or tied into existing HVAC ducts. Proper installation with flexible acoustic duct sections and vibration isolation keeps operational noise to a minimum.
What maintenance does an ERV require and how often should I service it?
Routine upkeep is simple: 1) Check and clean or replace the unit’s filters every 3–6 months (monthly during high-pollen seasons in East Tennessee). 2) Inspect and clean the core and condensate drain annually to prevent mold or mineral buildup. 3) Make sure outdoor air intakes remain clear of debris. A professional HVAC technician should perform a full tune-up once a year to verify airflow balance, motor performance, and heat-exchange efficiency.
