Different appliance categories have noticeably different typical service life expectations, largely driven by how mechanically complex they are and how continuously they operate. Refrigerators, which run continuously but have relatively few moving parts, often reach ten to fifteen years or more of service with reasonable maintenance, since their compressor cycles on and off but does not face the daily start-stop stress that some other appliances experience.
Air conditioners, particularly units running heavily during hot seasons, typically see a somewhat shorter practical service life in the range of ten to twelve years, influenced considerably by climate, usage intensity, and maintenance consistency, with coastal or highly humid environments often shortening this range due to accelerated corrosion. Washing machines, with more moving mechanical parts including the drum, motor, and various valves and pumps, commonly see service lives in the eight to twelve year range, with front-load models sometimes showing more sensitivity to water quality and detergent type than top-load designs.
Kitchen chimneys and exhaust fans, depending heavily on motor quality and how consistently grease filters are cleaned, show a wide service life range, since neglected grease buildup can shorten motor life considerably compared to a well-maintained unit of the same original quality. These ranges represent general patterns rather than guarantees, since individual unit condition depends heavily on specific usage and maintenance history.
