During a home inspection, a home inspector will check the manufacturer’s labels on appliances where/whenever possible and note life expectancy. This enables buyers to be prepared if an appliance’s age is high and nearing its general life expectancy and to plan for when it will need to be replaced. Aging appliances discovered during a home inspection, especially major household appliances like a refrigerator or an HVAC unit, can be used during negotiations.
