The answer to 'how long will replacement last' is that the lifespan of HVAC replacement components can vary significantly, but most parts typically last 10-15 years with proper maintenance. Major HVAC system components like furnaces, air conditioners, and heat pumps tend to have a lifespan of 15-20 years on average, while smaller parts like thermostats, filters, and motors may need to be replaced more frequently, often every 5-10 years.
The actual lifespan of HVAC replacement parts depends on factors like the quality of the equipment, how often it's used, and how well it's maintained. Proper maintenance, such as regular tune-ups, filter changes, and cleaning, can help maximize the lifespan of your HVAC system and its components. It's always a good idea to consult with a professional HVAC technician to get an accurate assessment of your system's condition and expected remaining lifespan.
