Due to the storm in NJ our factory is closed today.  We will re-open Monday March 1.  Our apologies for the inconvenience.

For the safety of our employees, ZONEFIRST has closed for today, Wed Feb 10 and will re-open Thurs Feb 11, due to the blizzard in Northern NJ.

Effective Jan 1, 2010, North Carolina mandated zoning of all newly installed HVAC Systems.  Zoning was defined as mutliple equipment or automatic damper systems.  It could also mean using manual dampers between seasons as well, however this is the first state truely recognizing zone damper systems.  This new code also requires room by room load calcs vs. one for the whole house. The next question is the meaning of newly installed and if this only means with new homes or a changeout.  See:http://www.nclicensing.org/_fpclass/_nosearch/New%20Rules%202010.pdf:
