They also answer emergency calls for gas leaks. To install gas appliances, they may have to install pipes in customers' homes to connect the appliances to the gas line. They measure, lay out, cut, and thread pipe and connect it to a feeder line and to the appliance. They may have to saw holes in walls or floors and hang steel supports from beams or joists to hold gas pipes in place. Once the gas line is in place, they turn on the gas and check for leaks.
Repairers also answer customers' questions about the care and use of appliances.
For example, they demonstrate how to load automatic washing machines, arrange dishes in dishwashers, or sharpen chain saws. Repairers write up estimates of the cost of repairs for customers, keep records of parts used and hours worked, prepare bills, and collect payment. Working Conditions Home appliance and power tool repairers who handle portable appliances usually work in repair shops which generally are quiet, well lighted, and adequately ventilated. Those who repair major appliances usually make service calls to customers' homes. They carry their tools and a number of commonly used parts with them in a truck or van and may spend several hours a day driving.
