FAQs
What is an Energy-Recovery Ventilator (ERV) and how does it work?
An ERV is a mechanical ventilation device that exchanges stale indoor air with fresh outdoor air while transferring heat and moisture between the two airstreams. In winter, it captures heat and some humidity from outgoing air to pre-warm and humidify the incoming fresh air. In summer, it removes heat and excess moisture from incoming air and expels it outdoors. This energy exchange reduces the load on your heating and cooling equipment, improving comfort and indoor air quality without wasting conditioned air.
Why are ERVs especially beneficial in Cookeville’s climate?
Cookeville experiences humid summers and cool, damp winters. An ERV helps manage both heat and moisture, making homes more comfortable year-round. During hot, muggy days it removes moisture before the air reaches your A/C coil, lowering indoor humidity and reducing the risk of mold. In the cooler months it recovers warmth and humidity that would otherwise be lost through ventilation, preventing the dry-air discomfort common in winter while cutting energy use.
Can an ERV be integrated with my existing HVAC system?
Yes. Most ERVs are designed to tie into existing ductwork or operate as a dedicated, stand-alone ventilation loop. A qualified HVAC technician will assess your current system, determine airflow requirements, and install the ERV so it delivers balanced fresh air without upsetting pressure in the duct system. Proper sizing and commissioning ensure the ERV works seamlessly with furnaces, heat pumps, or central A/C units already in place.
How much maintenance does an ERV require and what does it involve?
ERVs are low-maintenance but not maintenance-free. Filters should be inspected every 1–3 months and replaced or cleaned as needed to keep airflow unrestricted. The core (where heat and moisture transfer occur) should be cleaned at least once a year, usually by vacuuming or rinsing per the manufacturer’s directions. Fans, dampers, and condensate drains also need an annual check. Scheduling maintenance alongside your regular HVAC tune-up is an easy way to keep the ERV operating efficiently.
Will installing an ERV lower my energy bills?
Most homeowners see measurable savings because the ERV recovers 60–80 % of the energy that would normally be exhausted with stale air. By tempering incoming air, it reduces run-time for your furnace in winter and your air conditioner in summer. Exact savings depend on your home’s insulation, air-sealing, and how often you currently ventilate by opening windows or using exhaust fans. The U.S. Department of Energy estimates payback periods of 3–7 years for properly installed ERVs in climates like Tennessee’s.
What’s the difference between an ERV and an HRV, and which is better for Cookeville homes?
Both devices exchange stale indoor air with fresh outdoor air and recover heat. The key difference is moisture transfer: ERVs transfer both heat and humidity, while Heat-Recovery Ventilators (HRVs) transfer heat only. Because Cookeville has humid summers and can experience dry indoor air in winter, an ERV is generally the better choice. It helps remove excess humidity in summer while retaining comfortable moisture levels during the heating season, giving you balanced comfort and better energy performance year-round.
