An Energy Recovery Ventilator (ERV) is a ventilation system that exchanges stale indoor air with fresh outdoor air. The key difference between an ERV and a simple exhaust fan is its ability to transfer heat and humidity.

• Winter Benefits: The ERV captures heat from the outgoing indoor air and uses it to pre-heat the incoming cold, fresh air. It also transfers some moisture, which helps prevent your home from becoming too dry.

• Summer Benefits: The ERV captures the cool, conditioned air and uses it to cool down the incoming hot, fresh air. It also removes some humidity from the incoming air, reducing the load on your air conditioning system.

• Health and Comfort: By continuously circulating fresh air, an ERV helps to reduce odors, remove pollutants, and improve the overall feel of your indoor environment.
