The lifespan of an air conditioning system depends on the type and energy efficiency of the unit and how well it is maintained. Generally, window AC units last about 10 years and central ACs tend to last longer than window ACs.
- Central Air Conditioner Units: 14-20 Years
- Window Air Conditioners: 10 Years
The age of the unit is just one factor that affects how long an AC unit lasts. The quality and care of the unit, as well as the climate in which it operates, also play a role.
Window units and central air conditioning units usually last around 10 years if properly cared for and used in moderate climates, but may last up to 20 years in climates with mild temperatures.
The cost of repairing an air conditioning system depends on the unit’s age, type, and parts that need replacing or fixing. Costs can range from $100 to $100z0 for minor repairs (such as a replacement capacitor) and around $2000-$6000 for larger repairs (like compressor replacement).
The Average Lifespan of an Air Conditioning Unit
How long do air conditioners last? The lifespan of an air conditioning unit depends on the type and energy efficiency of the unit and how well it is maintained. Generally, window AC units last about 10 years and central ACs tend to last longer than window ACs. Central air conditioning units: 14-20 years Window air conditioners: 10 years.

Costs can range from $100 to $1000 for minor repairs (such as a replacement capacitor) and around $2000-$6000 for larger repairs (like compressor replacement). If an air conditioning system is still in good working condition but needs a new part, it’s best to replace the part. If a central air conditioning unit is about 15-20 years old, chances are that replacing the compressor, evaporator coil and condenser coil might cost less than if the compressor fails and you need to purchase a whole new unit.
Should I Replace or Fix My Old Air Conditioner?
If an air conditioning unit is still in good working condition but needs a new part, it’s best to replace the part. If a central air conditioning unit is about 15-20 years old, chances are that replacing the compressor, evaporator coil and condenser coil might cost less than if the compressor fails and you need to purchase a whole new unit.
If your air conditioner is older than 20 years, consider replacing it with a newer, more energy-efficient model that costs less to run, saving money in the long run. New models are much more efficient than those manufactured 15 or more years ago and will save you money on your energy bill.
