The answer to 'how long will system upgrade last' is that the lifespan of an HVAC system upgrade can vary, but typically ranges from 10 to 15 years with proper maintenance. The actual lifespan depends on factors like the quality of the equipment, how often it's used, and how well it's maintained.
Higher-efficiency HVAC systems that meet current energy standards tend to last longer than older, less efficient models. Proper installation, annual tune-ups, and addressing any issues promptly can also help extend the system's lifespan. It's generally recommended to plan for a system replacement every 10-15 years to ensure optimal performance and energy efficiency.
