Replacement guide
When should I replace my heat pump?
Heat pumps accumulate runtime across heating and cooling seasons — calendar age understates compressor hours versus straight AC-only units.
Manufacturer bands often imply 12–16 years effective life for earlier-generation air-source gear before inverter retrofit incentives tilt economics.

Estimated 2026 US ranges synthesize publicly reported homeowner project medians such as HomeAdvisor and Angi; labor context references BLS occupational wage patterns. Your quotes will vary by scope, code, and crew availability.
Typical lifespan (US median bands)
Dual-season duty cycles frequently compress median retirement versus standalone AC — 12–16 years appears commonly in HVAC contractor planning decks.
Cold-climate inverter units with vapor injection sometimes justify earlier tech swaps when utility rebates stack — even if legacy compressor still runs.
Signs you may be near end-of-life
Stuck reversing valves presenting heat-in-cool mode or vice versa after diagnosis often carry $900–$2,000 repair spreads — weigh age.
Outdoor coils shedding aluminum fines or icing excessively after confirmed charge may forecast coil fatigue.
Backup heat strips engaging excessively in mild weather implies COP collapse worth modeling against new HSPF ratings.
Estimated 2026 US replacement cost ranges
Illustrative 2026 US cold-climate heat pump + air-handler bundles frequently quote $9,000–$19,500 before duct sealing mandates.
Line-hide trenching, crane placement, or ampacity upgrades add discrete four-digit line items.
Repair vs replace decision grid
Compressor & valve economics dominate.
| Factor | Lean repair | Lean replace | Notes |
|---|---|---|---|
| Age system | <10 years | ≥14–16 years + compressor fault | Hours > calendar |
| Repair ticket | < 30–35% turnkey new | > 45–50% turnkey new | Compare inverter rebate nets |
| Comfort | Humidity & noise acceptable | Cold weather drafts / noise | Variable-speed handlers help |
| Refrigerant | Charge stable season-season | Annual winter summer top-offs | Leak search labor mounts |
