How Long Should My AC Unit Last?

When purchasing a new air conditioning unit, many people believe, or at least hope, the unit will last for many years. Unfortunately, there are several factors that will determine how long your unit will last. Of course, the type of air conditioner and overall care and maintenance are key, but where you live will also play a role in how long your unit lasts.

Another big factor is the quality of the installation. Improper installation will lead to frequent breakdowns and repairs.
A well maintained unit can last for as long as 15-20 years. However, where you live can decrease that number greatly. Beach front properties can typically get 8 to 15 years, but if they are not professionally serviced by a licensed HVAC contractor, their lifespan will be much shorter.

There are several things you can do as a homeowner to increase your unit’s lifespan. Replacing or cleaning air filters regularly is very important. If you use washable filters, be sure they are completely dry before replacing. You should have your unit serviced, at the very least, once per year at the beginning of the season. The technician can usually identify potential problems before they turn in to larger repairs.

If problems are constantly ignored or allowed to continue without being addressed, the overall life expectancy of the air conditioner will be much shorter as a result.
