Heat pump diagnostics and repairs in Wellington
If a heat pump is running badly, leaking, making unusual noises, showing fault lights or simply not heating and cooling as it should, the first step is finding the actual cause. Frost Industries provides diagnostics and repairs for major heat pump brands across Wellington and the Hutt Valley.
Our refrigeration and electrical experience means the focus is on fault finding rather than guessing. Once the issue is identified, we explain the repair options and whether repair or replacement makes more sense.
Heat pump problems we can investigate
- Unit not heating or cooling properly
- Error codes or flashing lights
- Water leaks or drainage issues
- Unusual noises or vibration
- Intermittent operation or failure to start
- Performance problems with older systems
Repair or replace?
Not every fault means a new heat pump is required. The decision depends on the cause of the fault, age and condition of the system, parts availability, likely repair cost and whether the unit was correctly sized and positioned in the first place. We explain what we find so you can make an informed decision.

Heat pump repair FAQs
My heat pump is running but the room is still cold. Is it broken?
Not necessarily. Restricted airflow, settings, heat loss, poor sizing or a system fault can all affect performance. Diagnosis helps separate an equipment problem from a design or room-related issue.
Do you repair heat pumps you did not install?
We diagnose and repair major heat pump brands, including systems installed by other companies.
Can you replace the system if it is not worth repairing?
Yes. If replacement is the better option, we can assess the space and recommend a new system. See our heat pump installation Wellington page.
Do you repair ducted heat pumps?
We can assess ducted heat pump faults as well as standard room systems. The work required depends on the system and the fault.
