EWC Controls Ultra-Zone Panels and Zone Dampers
A.J. LeBlanc Heating installs EWC Controls zone panels and dampers throughout Southern NH. EWC is the workhorse for converting a single-zone forced-air home into a comfort-zoned system, and their Ultra-Zone panels integrate cleanly with the furnace, heat pump, and thermostat brands we install.
Forced-Air Zoning Done Right
EWC Controls has been manufacturing forced-air zone control equipment in the United States for decades. Their Ultra-Zone panels coordinate up to four zones from a single furnace, heat pump, or air handler, opening and closing motorized dampers based on each zone thermostat's call. The result is even temperatures from one end of the house to the other and lower energy use, since you only condition the rooms that need it.
EWC Controls equipment is straightforward to retrofit into existing forced-air homes, and pairs cleanly with the smart thermostats, heat pumps, and air handlers we install across Southern NH.
