Refrigerators stay durable longer when they are maintained well, which includes cleaning the coils and replacing loose or broken seals. Refrigerators also stay durable when they are placed in a location with adequate room around them to accommodate vents.
Refrigerator coils should be cleaned once a year or more frequently if shedding pets live in the home. Another practice that helps refrigerators run more efficiently is to allow food to cool before storing it. Keeping the refrigerator fairly full also keeps the unit from working harder than necessary. Refrigerators typically last about 13 years, according to the National Association of Home Builders.
