How long do home appliances last? (2026 lifespan guide)
Average lifespans for water heaters, HVAC, refrigerators, washers, dryers, and dishwashers — plus signs it's time to replace.

TL;DR
- Tank water heaters: plan inside ~8–12 yr; tankless often ~15–22 yr with descaling every 12–24 mo.
- Central split AC: ~13–17 yr medians; ≥2 lb/yr refrigerant churn on older gear flags tail-of-life.
- Gas furnaces: ~15–24 yr with proper service; heat pumps commonly ~12–16 yr before major stack failures cluster.
- Asphalt roofs: ~22–29 yr architectural shingle medians—granule loss and tab curl are quantify-on-the-ground signals.
- Replacement medians in the table span roughly $0.4k–$19k by category before locality multipliers.
Appliance lifespan is a band, not a birthday: install quality, water chemistry, thermostat habits, coastal corrosion, batch variance, and service history widen or shorten tails by years.
This guide cites illustrative U.S. medians you can use for reserve planning—always validate with licensed pros before you capitalize.
Junyper stores ages, receipts, and maintenance so those medians personalize to your house instead of anonymous averages.
Table 1. Illustrative median U.S. lifespan bands & replacement cost deltas (national medians; metro variance ±30%)
| Appliance / system | Average lifespan band | End-of-life signs | Replacement cost median (installed, U.S.) |
|---|---|---|---|
| Tank water heater | 8–12 yr | Rust skirt, T&P dribble, rumbling sediment, rusty hot-only | $1.2k–$3.8k |
| Tankless water heater | 15–22 yr | Flame faults, HX leak, ignored descale faults | $2.9k–$5.9k |
| Gas furnace | 15–24 yr | HX concerns, rollout, soot, rising gas use | $5.5k–$10.5k |
| Central AC (split) | 13–17 yr | Refrigerant churn, soggy ducts, blower burnout | $5.9k–$14.9k |
| Heat pump | 12–16 yr | Defrost faults, reversing valve leaks | $7.9k–$18.9k |
| Refrigerator | 10–15 yr | Warm zones, frost pattern faults, rising kWh | $1.9k–$5.9k |
| Dishwasher | 10–13 yr | Wash motor hum, sump leaks, etched glass post-service | $0.9k–$2.3k |
| Clothes washer | 9–13 yr | Drum play, chronic MCU faults | $0.95k–$2.35k |
| Clothes dryer (electric) | 10–15 yr | Long dry post-vent clean, belt wear | $0.95k–$2.95k |
| Microwave (OTR) | 7–11 yr | Arcing cavity, keypad ghosting | $0.65k–$1.95k |
| Garbage disposal | 8–13 yr | Rotor seizure, flange leak | $0.39k–$0.82k |
| Roof (asphalt architectural) | 22–29 yr | Granule gutters, curled tabs | $11k–$35k job-dependent |
| Water softener resin tank | 10–17 yr | Iron breakthrough, brine faults | $1.85k–$4.95k |
Reading the variance
Coastal salt + electric tank WH + hard water pulls you toward the bottom of a band; temperate climates with treatment can stretch the top.
Annual coil cleanings and measured blower static often add ~2 years of effective HVAC life in aggregated trade studies.
Steep north-facing roofs hold moss—plan band compression 4–8 years versus sun-baked slopes.
Logging ages and service events in Junyper quantifies which side of the band you are actually on.
