The answer to 'how long does air handler last' is that the typical lifespan of an air handler is 10-15 years with proper maintenance. Air handlers are a key component of HVAC systems, responsible for circulating air through the ductwork and into your home. Their lifespan can vary depending on factors like usage, environment, and maintenance practices.
With regular professional tune-ups and filter changes, a well-cared-for air handler can often last at the higher end of that range or even longer. However, older units or those that have not been properly maintained may need replacement sooner. It's important to have an HVAC technician inspect your system periodically to ensure it is operating efficiently and safely.
