2 important features of any home HVAC system are energy-efficient function and the
maintenance of good indoor air quality. An energy recovery ventilator, or ERV, supports both factors and works
as an integral part of your complete heating and air conditioning system
A heating and air conditioning unit’s ERV improves the home’s
indoor air quality by exhausting stale, indoor air to the outside and
drawing fresh air in. This allows the system to flush out airborne contaminants
from your home. At the same time, an ERV’s core transfers excess
humidity from the ingoing outdoor air to the outgoing indoor air. In these
ways, an ERV improves your indoor air quality.
To prevent energy loss from exhausting conditioned air to the outside,
an ERV also transfers heat energy to and from the outgoing and ingoing
air through its heat exchange core. In this way, your heating and air
conditioning’s ERV can keep indoor air fresh while reducing the
amount of energy lost in the process.
