Does anyone know the approximate cost to run an AHU blower?
We are building a new house and is currently in mechanical rough-in. The ERV has been configured with the stale air fed from the return duct and the fresh air injected in to the return duct 5′ downstream from that. So the AHU blower will have to run along with the ERV and we’ll likely have to run the ERV more often to maintain good CO2/VOC levels in bedrooms at night.
We are talking to the HVAC folks about doing fully ducted. The numbers they are quoting are quite ridiculous. Is there a good way to guesstimate the cost savings for operating a fully ducted ERV vs what we have?
