Heating & Air Conditioning

New technology, in the form of cellular Web phones that allow technicians to tap into the Internet, may soon affect the way technicians diagnose problems. Computer hardware and software have been developed that allow heating, venting, and refrigeration units to automatically contact the maintenance establishment when problems arise. The maintenance establishment can then notify the technician in the field by cellular phone. The technician can then access the Internet to "talk" with the unit needing maintenance. Although this technology is not yet widespread, its potential for cost-savings may speed its acceptance.
