我的builder只是提到送HRV，但并没有说那么具体。我已email它们你的question.

If its true full dedicated system, no need to be interconnected to furnace. If its half dedicated system them it will be interconnected with furnace. If its simplified system, it's good to interconnected with furnace.

Hrv is for air exchange and required for energy star house(2012 become new building code requirement)

Dedicated installation normally only can be done for a newly built houses. Simplified system can be installed anytime
