ERV vs HRV what size unit and which is best?
I have a timber frame home with sips built in 2007. At the time we put in forced air heat with an aprilaire erv system tied to a trane furnace/ac and a aprilaire dehumidifier. I have always had a problem with condensation and humidity levels in the winter time. The arpilare rep said I need a hrv not a erv? Aprilare does not make a hrv which system would work with the duct work for the aprilare system and what size system do I need for a 2000 sq foot home with two levels?
