FAQs
What exactly is an energy-recovery ventilator (ERV) and how does it work?
An ERV is a mechanical ventilation device that pulls stale indoor air out of your home while simultaneously bringing in fresh outdoor air. Inside the core of the unit, heat and moisture are transferred from one airstream to the other, so in winter the outgoing warm air pre-heats the cold incoming air, and in summer the cooler, drier indoor air tempers the hot, humid outdoor air. This process reduces the workload on your heating and cooling equipment while maintaining a steady supply of fresh air.
Why are ERVs especially beneficial for homes and businesses in Turtletown?
Turtletown experiences hot, humid summers and cool winters. Traditional tightly sealed buildings trap moisture and pollutants, making indoor air stale or even unhealthy. An ERV addresses both issues: it expels excess humidity and contaminants while recovering up to 80 percent of the heating or cooling energy. This means you get balanced ventilation without the energy penalty normally associated with opening windows in our East Tennessee climate.
Can an ERV be added to my existing HVAC system, or do I need a complete replacement?
In most cases, an ERV can be integrated into your current forced-air heating and air-conditioning system without replacing the entire setup. We install dedicated ductwork (or tap into return and supply trunks) and tie the ERV into your system’s controls so it operates only when needed. Our technicians perform a ventilation load calculation first to determine the correct ERV size and the best connection points for optimal airflow.
How will running an ERV affect my monthly energy bills?
Because an ERV recovers heat and moisture that would otherwise be exhausted, it typically cuts ventilation-related energy loss by 50–80 percent compared with standard exhaust-only fans. Homeowners in Turtletown usually see overall HVAC energy savings of 10–15 percent, depending on building tightness and occupancy. Savings are higher during temperature extremes, when the ERV’s heat-exchange core has more energy to capture.
What maintenance does an ERV require, and how often?
Routine maintenance is simple: (1) Check and clean or replace the intake and exhaust filters every 3 months (more often if you have pets or live on a dusty road). (2) Inspect the heat-exchange core twice a year and lightly vacuum or wash it as specified by the manufacturer. (3) Make sure the condensate drain is clear to prevent water buildup. Our service plans include these tasks during your biannual HVAC tune-ups.
How does an ERV improve indoor air quality compared with regular exhaust fans or opening windows?
An ERV provides controlled, balanced ventilation: the exact amount of fresh air your home needs based on square footage and occupancy. Unlike bathroom or kitchen exhaust fans that create negative pressure and can draw in unfiltered air through cracks, an ERV filters the incoming air to remove pollen, dust, and outdoor pollutants. It also manages indoor humidity, discouraging mold growth and maintaining comfort levels year-round—something opening windows cannot guarantee during Turtletown’s muggy summers or chilly winters.
