What affects HVAC lifespan?
Runtime, sizing, airflow, filter condition, installation quality, outdoor environment and maintenance all matter. Equipment that cycles excessively or operates with restricted airflow can accumulate wear much faster than its age suggests.
Maintenance matters
Keeping filters, grilles and accessible airflow paths clean can help equipment operate as intended. However, sealed refrigerant systems, gas appliances and electrical faults are not appropriate DIY repair areas for most homeowners.
Age versus condition
Older equipment is not automatically due for replacement. Reliability, repair frequency, efficiency, safety and parts availability should be considered together.
