How Long Does an AC Last?
2026-07-31 4 min readBy Launch Air & Heating
AC lifespan in Florida is shorter than the national average. Here's what to expect and how to extend it.
How Long Should Your AC Last?
The Florida reality
Nationally, ACs last 15-20 years. In Florida, expect 12-15 years due to our long, demanding cooling season and salt-air exposure near the coast.
What shortens lifespan
- Skipping maintenance
- Dirty filters and coils
- Salt-air corrosion (coastal homes)
- Oversized or undersized systems
What extends it
- Annual professional maintenance
- Regular filter changes
- Keeping the condenser clean and clear
- Prompt repairs
Plan ahead
If your system is over 12 years old, start budgeting for replacement so you're not caught off guard in July.
