Professional Air Source Heat Pump Repairs
An air source heat pump is made up of several connected components, including the outdoor unit, fan, controls, hydraulic circuit, sensors and heating system. A fault with one part can affect the performance of the wider system.
At DV Plumbing & Gas Services, we take a structured approach to fault diagnosis. We assess the system, review the symptoms and check relevant components before recommending repair work.
​
Whether your heat pump has stopped working completely or its performance has gradually changed, we can help identify the issue and explain the next steps clearly.
​
We also support commercial properties, where heating or hot water problems can cause greater disruption to staff, customers, tenants or daily operations.
Our Air Source Heat Pump Repair Service
Fault Diagnosis
We start by understanding the symptoms and inspecting the relevant parts of your system. Our aim is to identify the underlying cause rather than simply replace parts unnecessarily.
System Performance Checks
We assess relevant system readings, controls and operating conditions to help determine where the fault may be occurring.
Component Inspection
The outdoor unit, fan, controls, hydraulic circuit and other accessible components are inspected according to the nature of the problem.
Repair Recommendation
Once the fault has been identified, we explain what needs attention and recommend the most appropriate repair.
Component Repair or Replacement
Where appropriate, we repair the faulty component or recommend a suitable replacement to restore system operation.
Testing & Final Checks
After repair work, we check the system to confirm that the relevant components are operating correctly and that the original issue has been addressed.
Common Air Source Heat Pump Problems We Repair
Heat Pump Not Heating
If your system is running but your property is not reaching the expected temperature, we can investigate the heating system and identify possible causes.
Error Codes & Warning Messages
An unfamiliar error code can indicate a problem with a component, sensor, control or system condition. We can assess the system and determine what requires attention.
Unusual Noise or Vibration
Changes in noise from the outdoor unit may indicate an issue with the fan, airflow, mounting or another component. We can investigate unusual sounds and vibrations.
Poor Heating Performance
If your heat pump is taking longer to heat the property or is struggling to maintain comfortable temperatures, we can assess system operation and performance.
Where the heat pump is responsible for domestic hot water, faults can affect water temperature, recovery or overall hot water availability.
