What Is an ERV, and How Does It Work?
ERVs essentially use the air that your HVAC systems send out through the exhaust. They utilize the energy of that air to precondition the new air that’s coming in from outdoors. This process “recovers” energy that would be loss. What does this mean? In the summertime, an ERV system pre-cools and dehumidifies the air that’s coming into your home, and in the wintertime, it pre-heats the air.
As a result, it can work together with your HVAC system to make sure that not only are you receiving the temperature you desire in your home, but that the air is fresh and offers the most comfort possible. This is far superior to opening a window to let fresh air in—since, after all, that will let your conditioned air out and defeat the purpose of even using an HVAC system!
Overall, an ERV system improves the ventilation of your household. The pre-treatment process improves indoor air quality by making it easier and more comfortable to breathe. ERV systems are capable of maintaining a relative humidity level of between 40-50%, which is considered most ideal for indoor air.
Other Indoor Air Quality Products That Can Help
An ERV system is not meant to replace a humidifier or dehumidifier if needed, however, it can supplement this type of system, reducing the likelihood for mold and mildew development. Mold and mildew are major concerns in larger homes and buildings, as well as any property that accumulates a lot of moisture—something that is fairly common here in the Tacoma area.
An ERV can help you breathe easier, and it’s not the only indoor air quality system that can help you do so. Ask us too about our air filtration systems, air cleaners, and air purifiers. Each of these systems have their own unique purposes and benefits. You may find that one or some combination of products is all you need to start breathing easier and feeling more comfortable in your home.
