Lifespan describes how long a water heater or HVAC system can operate effectively before replacement. It depends on equipment quality, installation, usage, climate, and maintenance. Typical ranges are about 10 to 15 years for many water heaters and 15 to 25 years for HVAC systems, with proper care extending those averages.
