It's no secret that air conditioners don't last forever. But how long does an air conditioner last? The answer isn't as straightforward as you might think. There are many factors that can affect the life expectancy of your AC unit, from the quality of the unit and the work done by the installation technician, to the climate and comfort preferences, to the good or poor maintenance of the system. Generally speaking, air conditioners that are properly maintained can last between 10 and 20 years.
Central air units will last 12 to 17 years with average use and good maintenance, while ductless mini-split systems can last up to 20 years. Heat pumps with air source can last up to 25 years if they are well maintained and in a well-insulated house. It's important to know how long air conditioners last so you don't get surprised when your AC breaks down in the heat of summer. Homeowners who know what affects the lifespan of their AC unit, as well as the signs that something is wrong with their system, can ensure that their air conditioner lasts a long and happy life. However, if you notice any problems with your system (from strange odors and noises to a system that doesn't blow cold air), contact an HVAC professional for immediate help. In addition, professional HVAC system maintenance should be part of your annual HVAC care checklist.
This will help extend the overall lifespan of your HVAC systems, in addition to covering replacement costs when it comes time to replace them.
