What Is an Energy Recovery Ventilator?

Air-tight properties can be great for energy efficiency, but not so great for good ventilation. However, there is a whole-home device that can be added to your existing HVAC system that helps with both energy efficiency and ventilation: an energy recovery ventilator, also known as an ERV. Your indoor air quality in Jacksonville is important for both comfort and health, and with an ERV, you can accomplish both healthy air and energy efficiency. J&W Heating and Air has been serving customers in the Jacksonville area since 1966, and we can help you with all of your indoor air quality needs.

How Does an ERV Work?

An ERV capitalizes on the second law of thermodynamics, which states that energy will spontaneously move from areas of high energy to areas of lower energy. The core of the ERV, known as the heat exchanger, transfers heat and moisture between incoming and outgoing streams. During winter, your warm, used indoor air is expelled. As it exits, it pre-heats the incoming cold air and also adds moisture to it. During the summer, your used conditioned air is expelled, and it pre-cools and dehumidifies the incoming warm air.

What Are the Benefits of an ERV?

There are several key benefits to installing an ERV:

  • Continuous clean, fresh air – an ERV brings in a constant, steady stream of air from the outside, which improves your ventilation and indoor air quality.
  • Better energy efficiency – pre-treating the air, whether during summer or winter, helps reduce the amount of work your HVAC system has to do. This can reduce the amount of energy it uses to operate.
  • Balanced humidity levels – an ERV manages moisture by either adding it or dehumidifying it according to the season, which helps maintain very balanced humidity levels in your home.
  • Less wear and tear on your system – an ERV reduces how much your AC has to work, which can reduce the rate of wear and tear.

An ERV can help your HVAC system be more efficient while also helping with indoor comfort and air quality. If you are interested in seeing what an ERV can do for your AC and indoor air quality in Jacksonville, call J&W Heating and Air today and schedule an appointment with one of our experts.
