Do You Know The Life Span Of These Items In Your West Knoxville Home?

When you buy a West Knoxville home, the home inspection reveals a lot of things about a home. One of the major issues that your inspection will explore is the age and condition of the major systems and items in a home.

This can be extremely important as a buyer since it can give you an idea when you may need to replace these items. For items like a roof or air conditioner, knowing if they’re on their last leg can be extremely important to know, for planning purposes. You may ask the seller to replace them or ask for a lower sales price since you’ll be replacing them soon.

In this post, we’ll share the of the expected life span of some of the major items in your West Knoxville home.

Kitchen Appliances

Kitchen appliances vary on their expected life span. There are many times where styles change and you may end up replacing our appliances before they end up dying out. There are other appliances, though, that need replacing on a more regular basis.


You can expect your dishwasher to last about 7 years.


You can expect a gas oven to last somewhere between 10 to 18 years.


You can expect your microwave to last for about 9 years.

Washer & Dryer

Washer typically will last between 5 and 15 years depending on the brand. Dryers will last about 14 years.

Heating & Cooling

Your heating and cooling elements are some of the most essential in your home. They keep you warm in the winter and cool during the summer. You can expect your central air conditioner to last anywhere from 7 to 15 years. A furnace, in contrast, does have a longer life span of 15 to 25 years. In addition, your thermostat will last up to 35 years.


Siding is another expensive item to replace. Here are the lifespans of some of the most popular types of siding:

  • Aluminum Siding – 25 to 40+
  • Brick – 100+
  • Engendered Wood – 100+
  • Stone 100+
  • Vinyl Siding – 60


Windows are another item that you may forget about replacing in your home. Windows can be responsible for letting the air in our homes out, making our heating or cooling systems inefficient. Here is the life expectancy of some of the common window types:

  • Aluminum – 15 to 20
  • Vinyl – 20 to 40
  • Skylights – 10 to 20
  • Wood 30+


The life of a roof is largely dependent on weather conditions, the design, building quality, and material quality. If you live in an area that experiences strong storms, your roof may experience a shorter lifespan.  Here is the life span of roofs that experience typical conditions:

  • Asphalt – 30
  • Clay/Concrete – 100
  • Metal – 40 to 80
  • Slate – 60 to 150
  • Wood – 30

Keep In Mind

Keep in mind, these estimates are based on these major items and systems experience normal wear and tear. In addition, these life spans take into account that these items were kept good condition, meaning that they were maintained properly and experienced routine maintenance. These should be just used as guidelines and make no warranties.

Worried? Get A Home Warranty

Home warranties help protect you against the unexpected.

If you’re someone who worries about things breaking, a home warranty may be a worthy purchase for you. By having a home warranty, you get yourself guaranteed protection for when something large breaks in your home.

If you want that kind of dependability and peace of mind, a home warranty can be a worthy investment. Just be sure you do your research and know what exactly the home warranty does and doesn’t cover. You don’t want to have something break only to find out that it is not covered by the home warranty.
