What is an Energy Recovery Ventilator?

Published on: July 26, 2013

Because clean, breathable indoor air is so important, adequate ventilation is a must when heating and cooling your home. Maximum breathability and comfort can at times be difficult to achieve, however. Particularly in the Southeastern U.S. where humidity levels are unusually high during the cooling season, finding the right balance between air temperature and ambient moisture can be a challenge. Fortunately, that’s one area where energy recovery ventilating systems, more commonly known as ERVs, can prove helpful. While other moisture-reduction options are also available, such as dehumidifiers and exhaust fans, the dual benefit of ERVs can make them a valuable addition to your humid-climate air conditioning and dehumidification efforts.

How Do Energy Recovery Ventilation Systems Work?

Basically, ERVs draw fresh air in from outdoors and deliver it to the interior of your home while removing stale, indoor air from your space and pumping it outside. They also remove humidity from the incoming airstream, transferring it to the exiting airstream to help maintain more balanced indoor humidity.

One factor that makes these ventilating systems even more valuable, however, is that unlike many other types of ventilating equipment, they reclaim much of the energy from the air and thus minimize the expenditure of energy by your HVAC system as it heats or cools your home. Because these systems are designed to recover energy that’s still present in the indoor air before venting it outside, ERVs are both energy-efficient and cost-effective. And while they may not be your main source of humidity control in very humid climates, they can help supplement other methods while making it easier and more cost-effective to ventilate your home.

Energy Recovery Ventilators Offer Many Advantages

ERV systems offer a variety of advantages that help maximize indoor comfort for you and your family:

  • Improved indoor air quality
