Life Expectancies of Appliances and Roofs in Florida

There are lots of items in a house that wear out with time and it is helpful to have an idea of the life expectancy of different systems and elements in a house.  Appliances are the most obvious, but here in south Florida our roofs  take a real beating from the climate.  Also, most of us run our air conditioners about 360 days a year  which means they wear out faster too.

When it comes to air conditioners and kitchen appliances, life expectancy depends a lot on how much use an item gets which can vary A LOT.  Some people may run their dishwasher several times a day while other use it very infrequently. Also, if “Snowbirds” have owned the property, it may have only been lived in for several months a year.

It is getting common for air conditioners to start needing repairs after 11 years but you can get more life out of it by making sure you change the filter every month, having it serviced annually, turning the thermostat up when you go out and even running it at a slightly higher temperature.  When deciding whether to repair or replace an air conditioner, consider how old it is and how efficient it is.  This is measured by the SEER rating.  Newer units have a higher SEER rating, meaning they are more efficient and often people cut their electric bill significantly when installing a new air conditioner.

Life expectancy varies with how much it is used, weather, installation, maintenance and quality of  the product and materials. This is just  a general guideline and not as a guarantee or warranty regarding the performance or life expectancy of any appliance, product, system or component.  Items may fail sooner or last a lot longer.
