# How long does an AC unit last in Lake Worth's coastal climate?

A properly maintained AC unit in Lake Worth typically lasts **8 to 12 years** — shorter than the 10–15 year national average because the city's coastal exposure and year-round cooling load accelerate wear on outdoor components.

Factors that affect AC lifespan in Lake Worth:

- **Distance from the Atlantic:** Homes east of Federal Highway (beach area, Parrot Cove, waterfront Lucerne Avenue properties) typically see 8–10 year lifespans; inland homes in Lake Osborne and Lake Clarke Shores often reach 11–13 years.

- **Maintenance frequency:** Biannual maintenance extends lifespan by 30–40% in this climate.

- **Protective measures:** Corrosion-resistant coil coatings, surge protectors (Florida lightning is brutal), and regular salt-rinse services meaningfully extend unit life on coastal properties.

- **Installation quality:** Properly sized and charged units last significantly longer — particularly important in historic Lake Worth homes where original installs were often compromises.

- **Hurricane exposure:** A single hurricane can end an otherwise healthy unit through water intrusion or debris impact.

If your Lake Worth AC is approaching 10 years, call Gulfstream Cooling at **(561) 531-3665** for an honest assessment.
