Hi Groutguy. Checked the referenced web site. They are an exclusive rep for a DX system, copper pipe and refrigerant, not water. They do have two listed reps within 100 miles of us and have called both. Will see what develops. Have not studied the DX system yet, was thinking of the HDPE and water systems, but am willing to look at other options. The only California listed IGSHPA designer refered me to a local installer. Installer has yet to return calls. Small steps. |
