Life Expectancy Of Ten Home Components

Home components are also known as home appliances. Each has a different life expectancy that is based on the frequency of use. Keep in mind that these numbers are only estimates and that they correspond to proper operation as per the instructions of each machine's manufacturer.

1. Air Cooling Systems - Depending on the type of cooling system, life expectancy is between 12 to 25 years, with whole house systems on the short end and gas air chillers on the higher end of the range.
2. Heating Systems - Depending on the type of heating system, they are replaced between 10 and 12 years of age.
