How Long Do Air Conditioning Units Last?

The lifespan of an air conditioning unit depends on factors such as usage, maintenance, and environmental conditions. On average, central air conditioning systems last 12 to 15 years, while ductless mini-split systems can last 15 to 20 years with proper care. Regular maintenance, including filter changes and coil cleaning, can help extend the life of your unit and improve energy efficiency.

  • Central AC systems last 12-15 years
