How Energy Recovery Ventilators Improves Indoor Air Quality

On average, people in the U.S. spend 90% of their time indoors, and that means the quality of the air found inside homes and buildings is vital for good health. Unfortunately, too few buildings have the proper ventilation to remove stale air, and the indoor air quality suffers as a result. The quality of your home’s air is probably much lower than it should be.

To combat this decline in air quality, you can open up your home to the outside through the windows and doors. However, this ends up breaking the energy efficient heat seal on your home, making it harder for you to keep cool in summer and warm in winter. During an Illinois winter, you especially don’t want to have windows and doors open!

But there’s a way to receive fresh outdoor air without energy loss and discomfort: have installation of energy recover ventilators in Bolingbrook, IL. Our team at DuAll Heating & Cooling is familiar with these helpful devices, and we’ll explain how they give you better indoor air quality.

How energy recovery ventilators work

Energy recovery ventilators (ERVs) are installations in the ventilation network of your HVAC system that remove the stale air from your home—without losing excess energy, either too keep you cool or keep you warm. An ERV returns approximately 85% of its outgoing energy to the incoming fresh air.

Here’s how an ERV does this: The ventilation system runs to the outside of a home and pulls in fresh outdoor air. The ERV draws the stale air from inside the house and runs it past the incoming fresh air, and a process of heat transfer occurs between the two that is called counter-flow heat exchange. If the air from outside is cold, then the stale indoor air transfers its heat to it, helping you receive warm fresh air. If the air outside is warm, it will lose its heat to the colder air from indoors, helping you to receive cool fresh air.

So whether its winter or summer, you receive fresh outdoor air that has been conditioned to fit your temperature needs. This will also reduce the stress on your heating and cooling system.

An energy recovery ventilator is like having your home’s windows and door always open to fresh air—but without any of the inconveniences. In fact, you’ll save more energy than ever before.
