Looking to add an HRV to a new home plan, 2500 sq.ft.
Concerned with humidity levels in Massachusetts. Very humid summer. Dryer winter. House will be close to net zero.

Joseph,
Here is a link to an in-depth review of the CERV: A Balanced Ventilation System With a Built-In Heat Pump.
It seems to me to be a good match to your needs. Summers with modest heat and high humidity are not well served by most of the options on the market, particularly in a well insulated house.
If you like being an early adopter of clever HVAC equipment, another option to consider is the Comfortdry 250 solar desiccant dehumidifier.

That doesn't substitute for ERV/HRV, but with a solar collector it can give you "free" dehumidification, which is quite enticing as we come to the end of a very humid August in the Northeast. You could potentially use that same solar collector for domestic hot water year round--if it's sized to provide a good fraction of your winter hot water needs, it's oversized for summer, and the extra hot water can be used for dehumidification.
