I know this has been beat to death on here, BUT.
Climate = Maryland (mixed humid)
House = 2 story cape, open great room, SPRAY INPLACE FOAM
Dual Infinity heat pumps.
This house is getting a dehumidifier w/fresh air intake.
While this will controll indoor humidity, is it enough for air exchange in a tight house ? or should an ERV be added for winter time use and the Ultra-aire for summer ? While the ultra-aire has fresh make up air, it does not extange as an HRV/ERV would.
I would seem that I need 2 systems to takle 2 seperate issues.
The HVAC contractor has an April-air ERV sitting in the basement (it is bought and paid for), but I am trying to hammer out exactly what systems I realy need and want in this home.
Any idea's , TB?
