How long does a air conditioner last?
Most air conditioners last 12 to 17 years. Yearly servicing, the local climate and how hard it works all move it within that range. Past 12 years, it is worth getting a replacement price before the unit fails, so you aren't forced into a rushed decision.
Air conditioners made before 2010 almost always use R-22 refrigerant, which is no longer produced in the US. If an older unit leaks, replacing it is often cheaper than recharging it.

- Ac condenser coil cleaner: Dirty outdoor coils make an older unit work harder.
- Furnace air filter: The indoor filter matters for cooling too.
