I have a two-zone forced air HVAC system with EWC controls installed about 15 years ago. One of the zone dampers, of a type driven by what look like little clock motors, has failed. I have had two local HVAC contractors work on the system, but neither of them is familiar
with EWC controls and both have been unable to fix the system. The second of them simply disconnected the failed damper, leaving it always open, so I no longer have a two zone system. I need an HVAC contractor in the greater Boston area who uses EWC controls and might be able to fix my system? – or a local distributor who can refer me to such a contactor?

I believe Jason got in touch with you regarding this. If you need further assistance, please feel free to contact us.
