A properly maintained Carrier HVAC system typically lasts 15–20 years. Rooftop units and commercial systems can last 20+ years with regular preventive maintenance. Key factors affecting lifespan include installation quality, filter changes, annual tune-ups, and how hard the system works—particularly important given NYC's demanding seasonal temperature swings from humid summers to cold winters.
