The answer to 'how long does replacement last' is that the lifespan of HVAC equipment can vary significantly, but on average, most systems will last 10-15 years with proper maintenance. The exact lifespan depends on factors like the quality of the equipment, how well it was installed, and how well it's maintained over the years.
Proper maintenance is key to maximizing the lifespan of your HVAC system. This includes regularly changing air filters, scheduling professional tune-ups, and addressing any issues as soon as they arise. With diligent care, many HVAC systems can exceed the 15-year mark. However, once a system reaches 10-15 years old, it's generally recommended to start planning for a replacement to avoid unexpected breakdowns and improve energy efficiency.
