The typical range
10 to 16 years
That is the typical service life for a heat pump on the published range. It is a range for the type, not a promise about the unit in your house. Some run well past the far end; some stop short of the near end.
Range source: click-4-coverage.com SYSTEMS table (src/lib/systems.ts, main, read 2026-10-16). Category: Heating and cooling.
Independent figure: InterNACHI chart: Heat Pump: 10 to 15 years (undated); NAHB 2007: Heat Pumps: 16 years. It is not the same as the published range above. Both are printed so you can see the difference; the published range stays the ranked value on every table on this site.
The biggest lever
How many months a year it runs. A heat pump heats in winter and cools in summer, so it runs in more months of the year than an air conditioner or a furnace does, and it stacks up hours faster. Climate is the lever. Degree days are the plain way to measure a climate, and the seasonal pages carry them.
On your walk-through
- Read the data plate on the outdoor unit and write down the date.
- Clear the outdoor unit on every side, and keep snow and ice off the top in winter.
- Note whether the house has backup heat and what kind it is.
How it stops, in plain words
Failure mode: Seasonal
It works hardest in one season, so trouble tends to show up in the first hard week of that season, when every technician in town is booked. Testing it a few weeks before the season turns is the whole point of the fall and spring checklists.
When to plan: a date, not a symptom
Do not wait for a noise or a puddle to start thinking about a heat pump. Work it out from the install year instead. Add 10 to the year it went in: that is the year the typical range opens, and the year to price it, budget for it and decide what you would do. Add 16: that is the year the range closes.
Put the opening year on your calendar today. Age is a planning input, not a diagnosis, and nothing on this page says your unit will stop in any given year.
| Installed | Age in 2026 | Range opens | Range closes | Where 2026 falls |
|---|---|---|---|---|
| 2004 | 22 | 2014 | 2020 | past the far end of the range |
| 2008 | 18 | 2018 | 2024 | past the far end of the range |
| 2012 | 14 | 2022 | 2028 | inside the range |
| 2016 | 10 | 2026 | 2032 | inside the range |
| 2020 | 6 | 2030 | 2036 | before the range opens |
| 2024 | 2 | 2034 | 2040 | before the range opens |
Arithmetic only: install year plus 10, install year plus 16, and 2026 minus the install year. No other figure is used.
If you cannot find the install year
Look for a data plate or label on the unit. Many carry a manufacture date, or a serial number that encodes one; the maker's site or a technician can decode it. Until you have a date, write the age down as unknown rather than guessing, and ask for it to be read at the next service visit.

The cooling side gets one too: the spring air conditioning walk-through.
