How Long Does an Air Conditioner Last?
Central air conditioners last 12–17 years in mild climates and 10–14 years where they run most of the year. Heat pumps land slightly lower because they also run in winter; mini-splits reach 15–20 years with regular cleaning.

Service life by type
Expected years in normal residential service before replacement.
| Type | Years | Notes |
|---|---|---|
| Central split-system AC | 12–17 | Coastal salt air can halve outdoor coil life. |
| Heat pump | 10–15 | Year-round runtime accelerates compressor wear. |
| Ductless mini-split | 15–20 | Inverter compressors cycle less aggressively. |
| Packaged rooftop unit | 10–15 | Full weather exposure shortens cabinet and coil life. |
What shortens it
- • Undersized return ducting
- • Skipped filter changes
- • Oversized equipment short-cycling
- • Coastal salt corrosion
- • Continuous high cooling-degree-day load
What extends it
- • Twice-yearly professional service
- • Correct refrigerant charge and airflow at commissioning
- • Clean coils and clear condensate line
- • Right-sized equipment from a Manual J load calculation
Signs it is time to replace
- • R-22 refrigerant system with a leak
- • Compressor or coil failure out of warranty
- • Repair cost above roughly one third of replacement
- • Rising utility bills with no comfort improvement
Insurance implications
HVAC age rarely blocks a policy, but it does gate the claim
Carriers commonly change how they underwrite this system at about 15 years of age. Thresholds vary by carrier and state — check your declarations page.
Underwriting
- • Condition and age appear on 4-point inspections, though HVAC is a weaker underwriting trigger than roof or panel.
- • Home warranty products, not homeowner policies, are what actually cover age-related HVAC failure.
At claim time
- • Lightning, fire and covered-peril damage to the condenser are payable; compressor burnout from age or wear is not.
- • Condenser theft or vandalism is covered but often subject to the standard deductible, which can exceed the repair.
What to do
- • Keep annual service records — they are the practical difference between a paid claim and a wear-and-tear denial.
- • Add a surge protection device at the panel or disconnect; several carriers recognise it, and it protects the board.
