I replaced an existing 4 ton air/air heat pump with a 4 ton straight cool/ hot water hydronic coil air handler.
The new air handler sucks or pulls the condensation off of the evaporator coil and slings it throughout the interior of the air handler cabinet.
The new evap. coil has been cleaned of any manufacturing oils. External duct static seems to measure around .2" WC.
The manufacturer's rep. says there is no way the ESP can be that low. I'm mainly a boiler guy and this is a project at my own home, and I'm looking for help.
