The answer to 'lifespan of air handler' is that the typical lifespan of an air handler unit is 15-20 years with proper maintenance. Air handlers are the indoor component of a central air conditioning or heat pump system that circulates the heated or cooled air throughout the home. With regular professional servicing and basic DIY maintenance, most air handlers will last for 15-20 years before needing replacement.
The lifespan can vary depending on factors like the quality of the unit, how often it's used, and how well it's maintained. Proper airflow, clean filters, and periodic professional tune-ups are key to maximizing the lifespan of an air handler. Homeowners should watch for signs of wear like unusual noises, reduced airflow, or frequent cycling to know when it may be time to replace the unit.
