Is Your Heat Pump Worth Repairing or Time to Replace?

How long should a heat pump last?

Air-source heat pumps often serve for roughly a decade to two decades, depending on climate, run hours and care. Because they work year-round for both heating and cooling, they can wear faster than a furnace or air conditioner alone. For ranges across equipment, see heating system lifespans in Canada.

Ground-source systems follow a different pattern: the indoor unit ages like other equipment while the buried loop can last much longer. That case is in ground source heat pump lifespan.

Which faults are usually repairable?

• Fan motors, capacitors, contactors and circuit boards.
• Defrost sensors or reversing-valve issues, if caught early.
• Refrigerant leaks at accessible fittings.
• Condensate drainage problems and frozen coils caused by airflow or filter issues.

Many of these follow from poor maintenance, so a routine from the heat pump maintenance checklist can prevent repeat callouts. If the unit ices up heavily or makes odd noises, read defrost and noise first, since normal defrost cycles are sometimes mistaken for faults.

When does a compressor or refrigerant problem tip toward replacement?

A failed compressor is the costliest common repair. On an older unit out of warranty, the repair bill can approach the price of a replacement, and a new compressor in an old system does not renew the coil, the controls or the rest of the equipment. Ask the technician whether the compressor failed from age or from an underlying fault such as low refrigerant, which could kill a replacement too.

Refrigerant matters as well. Some older refrigerants are being phased out, which can make recharging expensive or limited. Ask which refrigerant your system uses and whether supply is expected to be a problem. Do not accept a repair quote that adds refrigerant without finding the leak.

How do you judge a repair quote?

1. Is the diagnosis written, with test readings such as pressures, temperatures and amp draws?
2. Is the failed part named and its cause explained?
3. Is the warranty status checked, covering parts, labour and the compressor?
4. Is the price itemized, and does it include a second visit if the first fix does not hold?
5. What is the unit's age, and what would a replacement quote look like?

A second opinion is reasonable when the quote is large. Use the same discipline as in comparing heat pump quotes.

What if you are leaning to replace?

Treat a replacement as a fresh design, not a like-for-like swap. Ask for a new load calculation, since the house may have changed since the first install. Check current incentive terms with federal and provincial energy pages and your utility, not just the contractor. A servicing history from heat pump servicing records also helps when you negotiate warranty terms on the new unit.

What does a repair visit cost you besides parts?

Besides the part itself, a repair bill usually includes a diagnostic or call-out fee, labour by the hour and sometimes a refrigerant charge. Ask which of these apply and whether the diagnostic fee is credited if you go ahead. Prices vary by region and season, and emergency visits in the dead of winter often cost more than a booked one.

Keep a simple log: dates, symptoms, what was done, who did it and what it cost. A log makes patterns obvious, such as a coil that ices up every February, and it gives you leverage when a warranty claim or a second opinion is needed. It also helps a future buyer see that the equipment was looked after.

If two repairs in a row have not solved the problem, stop and ask for a full system evaluation instead of another single-part fix.
