When Age Isn't Just a Number

Black electrical cords on whiteSo you’ve finally found the home of your dreams – congratulations! Now you’re considering making an offer. You’ll probably want to take a look at the Seller’s Property Disclosure Statement to see if there are any red flags. It offers a lot of information including the age of some of the home’s systems. What do those numbers really mean? How long should you expect an appliance or system to last? Here is a quick breakdown of average lifespans:

  • Roof: 20-30 years
  • Furnace: 15-20 years
  • Air Conditioner: 10-15 years
  • Water Heater: 10-15 years
  • Refrigerator: 13 years
  • Stove/Oven: 13-15 years
  • Microwave: 9 years
  • Dishwasher: 9 years
  • Garbage Disposal: 12 years
  • Washer and Dryer: 10-13 years


Obviously the level of past maintenance will play a part in the lifespan of an appliance or system, but these averages give you a good idea of what to expect. You’ll know how to budget for replacement if any of these seem to be nearing their end of use or perhaps you could get a home warranty to cover any unexpected issues that may arise. Need help navigating this? The Peters Company would love to help!
