VOC problem, are ERV that efficient? I work in Louisiana in a car paint store with VOCs. This forum make it clear to me that phi, and hydroxyl radicals won't cure it, but ventilation will. The problem is my AC guy is already bringing in roughly 600 cfm of fresh air intake, but not exhausting it. (I think this means the rooms have a positive air supply) I think it is also only going to bring fresh air only when the AC fan is on. Right now when the fan locked to the on position the paint fumes are improved but I think we can do a little better.
Will an ERV with 1000 CFM's truly be more efficient? Will the savings in energy over 2 years pay off the cost of the ERV? In 5 years?
