Heat Pump Repairs & Diagnostics
Fault finding, repairs and performance checks for air source heat pump systems, with a focus on identifying the real cause rather than just resetting faults.

Common heat pump issues
- Fault codes or lockouts
- Poor heating performance
- Hot water issues
- High running costs
- Noisy operation
- System cycling or short running
Heat pump fault finding
A heat pump fault can sometimes be caused by settings, flow issues, controls, filters, sensors or system design — not just the heat pump unit itself.
System diagnostics
Checking the heat pump, controls, temperatures, pressures and system behaviour to understand the fault properly.
Performance issues
Investigating poor heating, hot water problems, short cycling or systems that are not reaching temperature.
Efficiency problems
High bills can sometimes be caused by poor settings, excessive flow temperatures or incorrect controls.
What we check
Good fault finding looks at the full heating system, not just the error code.
01 — Heat pump unit
Basic operation, fault history, temperatures, outdoor unit condition and visible signs of issues.
02 — Heating system
Flow, circulation, filters, emitters, pipework and system pressure where applicable.
03 — Controls
Schedules, compensation settings, thermostats, sensors and how the system is being controlled.
Repair, service or optimise?
Not every heat pump problem needs a major repair. Sometimes a service or optimisation visit can resolve comfort and efficiency issues.
Repairs
For faults, lockouts, failed components, hot water problems or systems not operating correctly.
Servicing
For annual checks, cleaning, maintenance and general system health.
Optimisation
For high running costs, comfort issues, cycling or systems that may not be setup efficiently.
Heat pump repairs FAQs
Can you repair heat pumps you didn’t install?
In many cases yes, depending on the system type, fault, condition and availability of parts.
Why is my heat pump using too much electricity?
High running costs can be caused by high flow temperatures, poor controls, incorrect settings, short cycling or system design issues.
Can a service fix a heat pump fault?
Sometimes. Dirty filters, poor circulation or incorrect settings can cause issues that may be picked up during servicing.
Do you offer optimisation as well as repairs?
Yes. If the system is working but not performing efficiently, optimisation may be the better route than a repair.
