Mechanical System Lifespans

Mechanical system lifespans are planning ranges, not promises: furnaces and heat pumps often span roughly 10–20 years depending on runtime and care; tanks commonly 8–12; tankless longer with descaling — Kitsap damp and salt can shorten neglect.

HVAC ranges

Outdoor units near salt spray and never-serviced filters fail earlier. Variable-speed systems still need airflow health to reach design life.

Plumbing ranges

Water heaters, supply lines, and fixtures age differently. Galvanized and polybutylene stories deserve inspection.

Using age in decisions

Pair age with repair frequency, parts availability, and efficiency goals — not age alone.

Budgeting replacements

Align reserves with published Eagle pricing orientation ranges when you are within a few years of end-of-life.

What goes wrong when homeowners wait

Assuming a 30-year-old furnace is fine because it still runs ignores efficiency, safety, and sudden failure risk. Replacing everything at once without phasing can strain cash unnecessarily.

Frequently asked questions

Does maintenance always extend life?

It improves odds; it cannot reverse a failed heat exchanger.

Should I replace before it dies?

When repairs cluster and efficiency or safety lag — proactive beats flood-night swaps.

Do ductless heads last as long as outdoor units?

Fan coils have their own wear; both matter in planning.
