In years past, the best way to achieve efficient temperature control in larger homes was with dual heating and cooling systems. However, in many homes, modern zoning systems not only provide better temperature control, they also may be more profitable to install.
That may be something of a surprise to contractors who have avoided specifying zoning in the belief that it would price their bids above competitors’ two-system bids. A cost analysis of the alternatives shows that zoning could actually provide a competitive advantage.
