The answer to 'how long does evaporator coil last' is that the average evaporator coil in a residential HVAC system lasts 10-15 years with proper maintenance. Evaporator coils are a critical component in your air conditioning system, responsible for absorbing heat from the indoor air and transferring it outside. Over time, these coils can become dirty, damaged, or wear out, reducing their efficiency and eventually needing replacement.
The lifespan of an evaporator coil can vary depending on factors like the quality of the unit, how often it's used, and how well it's maintained. Proper maintenance, such as regular cleaning and professional tune-ups, can help extend the coil's lifespan. However, even well-maintained coils will eventually need to be replaced as they naturally degrade over time.
