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 humidity from the outgoing exhaust air and pre-heats and humidifies the incoming fresh air; in summer, the process is reversed, helping to keep incoming air cooler and drier. This energy exchange reduces the load on your heating and cooling equipment while providing a continuous supply of fresh, filtered air.
Why is an ERV important for homes in Jonesborough’s climate?
Jonesborough experiences hot, humid summers and cool, damp winters, which often lead homeowners to keep windows closed for much of the year. This seals pollutants and excess moisture indoors. An ERV solves this by delivering controlled ventilation without wasting conditioned air. Because it also manages humidity, an ERV helps prevent mold growth common in the Appalachian region’s moist climate while keeping heating and cooling costs in check.
How does installing an ERV improve indoor air quality and comfort?
An ERV continuously dilutes indoor pollutants such as VOCs from paint and furniture, pet dander, cooking odors, and airborne viruses by exhausting them outdoors. At the same time, replaceable filters capture pollen and dust in the incoming air—particularly useful during East Tennessee’s high spring pollen counts. By balancing humidity, the unit reduces dryness in winter (helping with respiratory comfort and preventing cracking woodwork) and limits stickiness in summer, leading to a more comfortable, healthier living environment.
Will an ERV increase my energy bills?
In most cases, an ERV lowers overall energy costs. Traditional ventilation methods—like opening windows or using exhaust fans—force your HVAC system to re-heat or re-cool incoming air. An ERV’s heat- and moisture-exchange core recovers up to 70-80 % of the energy that would otherwise be lost, meaning your furnace or air conditioner runs less often. The unit’s small, efficient fan motors add only minimal electricity usage, typically a few dollars per month.
Can an ERV be integrated with my existing HVAC system?
Yes. ERVs are designed to work alongside nearly any forced-air HVAC system, including heat pumps, gas furnaces, and central air conditioners. Our technicians connect the ERV’s ductwork to your supply and return plenums so fresh air mixes evenly throughout the home. For houses without ductwork, stand-alone and multi-port ERV models are available. A professional assessment will determine the best installation approach for your home’s layout and airflow requirements.
How often does an ERV require maintenance and filter replacement?
Routine upkeep is straightforward. Filters should be inspected every three months and replaced—or washed if reusable—when dirty. The heat-exchange core typically needs cleaning once or twice a year, which involves sliding it out and rinsing it with mild soap and water. Fans and grilles should be vacuumed at the same interval. During a yearly HVAC tune-up, our technicians will check airflow, confirm balanced operation, and ensure the condensate drain is clear, keeping your ERV running efficiently for 15–20 years.
