Direct answer
What this service involves
A heat-pump fault can sit in the refrigeration circuit, water circuit, controls, sensors, electrical supply or system design. Good diagnosis starts with symptoms and operating data before parts are changed.
When it may suit your home
Contact us for loss of heat or hot water, repeated error codes, unusual cycling, new noise, pressure problems, icing that does not clear, or an unexplained rise in electricity use.

Clear answers
Heat pump repairs: frequently asked questions
Answers are shown in full so they remain useful and accessible. Property-specific decisions still require survey evidence.
Should I reset the heat pump?+
One reset may clear a transient fault, but repeated resets can hide a developing problem. Record the code and seek advice.
Why is the outdoor unit icing?+
Temporary frost can be normal and should be managed by defrost cycles. Persistent ice or poor heat output needs investigation.
Do you repair both air and ground source systems?+
Yes, the confirmed service scope includes repair support for both technologies, subject to model and parts availability.
What information helps before a heat pump repairs visit?+
Share the property type, current heating fuel, recent energy use where available, comfort problems, planned building work and photographs of the existing equipment. This helps us identify the right survey or diagnostic visit.
How is heat pump repairs priced?+
A reliable price follows a defined scope. Equipment, access, diagnostic or heat-loss work, emitter and cylinder changes, electrical work, controls, commissioning and aftercare can all affect the quotation.

Service-specific evidence
What we verify for heat pump repairs
Diagnosis uses the fault history, operating temperatures, flow, pressure, controller data and physical checks to narrow the cause. A displayed error can be triggered by a sensor, water-side restriction, control input, electrical problem or refrigeration fault, so replacing the named component is not automatically the right repair.
We separate the immediate fault from contributing conditions such as blocked airflow, poor water quality, repeated loss of pressure, inappropriate settings or short cycling. The homeowner receives the finding, proposed repair and any follow-on system recommendation before further work.
Decision record
What should be clear before work begins
The quotation should connect the recommended work to property evidence, state provisional items and distinguish installer responsibilities from third-party or homeowner work. Costs and performance expectations remain conditional on the written assumptions.
