What is the typical lifespan of a residential A/C system?

The typical lifespan of a residential air conditioning system is generally accepted to be around 10 to 15 years. Various factors influence this lifespan, including how well the system has been maintained, the climate in which it operates, and the quality of the installation. Regular maintenance, such as filter changes and seasonal inspections, can help extend the life of the unit, while neglecting these aspects can lead to premature failures.

Choosing this timeframe reflects the balance between optimal usage and the reality of wear and tear on the system over the years. A system that is used in a harsh environment or runs frequently due to poor insulation may not reach even the lower end of this estimate, while systems in milder climates with consistent upkeep can last longer, often approaching the upper end of the range before needing significant repairs or replacement.
