Common Heat Pump Problems and Warning Signs
Heat pumps can experience faults for several reasons. Some relate to the outdoor unit, while others may involve the heating controls, circulation system or wider installation.
Heat Pump Not Heating the House Properly
If your home takes longer than usual to warm up, or rooms are consistently colder than expected, there could be an issue with the system settings, heat distribution, airflow or equipment performance.
Heat pumps often operate differently from traditional boilers, providing steadier heat over longer periods. However, a noticeable change in performance should not be ignored.
Heat Pump Making Unusual Noises
A heat pump's outdoor fan and compressor naturally produce some operating noise. New rattling, grinding, persistent vibration or unusually loud operation may indicate a problem that needs investigation.
Check that the area around the outdoor unit is clear of leaves and other visible obstructions. If the noise continues or the equipment appears damaged, arrange a suitable inspection rather than attempting to dismantle the unit yourself.
Heat Pump Switching Off or Showing an Error
Repeated shutdowns, warning lights or error codes can indicate that the system has detected a fault.
Make a note of any error message displayed and check the manufacturer's instructions. This information can help a suitably qualified technician investigate the problem.
Avoid repeatedly resetting a system that continues to shut down, particularly if you notice burning smells, damaged wiring or other signs of an electrical fault.
Higher Energy Use Than Expected
A sudden increase in electricity consumption may be worth investigating, particularly if your heating habits and the weather have not changed significantly.
Possible contributing factors include incorrect settings, restricted airflow, changes in heating demand or a system fault. Cold weather alone can increase energy use, so consumption should be assessed in context rather than assuming the heat pump is faulty.
What Does Heat Pump Servicing Involve?

The precise maintenance requirements depend on the make, model and installation. A suitable service should follow the manufacturer's instructions and take account of the particular system installed in your home.
Depending on the equipment and the scope of the service, checks may include:
- Outdoor unit inspection: Checking the casing, accessible components and surrounding area for visible damage or obstructions.
- Airflow and fan checks: Looking for restrictions that could affect the movement of air through the outdoor unit.
- Heating system performance: Assessing system operation and relevant settings to identify potential performance issues.
- Controls and operation: Checking relevant controls, operating modes and any displayed warnings.
- Visible pipework and connections: Looking for signs of damage, deterioration or leaks where accessible.
- Fault identification: Investigating reported symptoms and identifying whether further diagnostic work or repairs are required.
Not every item will apply to every system, and the exact checks should be confirmed with the service provider before booking.
Heat Pump Repairs: Finding the Cause of the Problem
When a heat pump develops a fault, replacing parts without identifying the underlying cause can lead to unnecessary expense. Proper fault finding helps establish what has gone wrong and which repairs, if any, are appropriate.
Depending on the fault, an investigation may involve the outdoor unit, fan operation, controls, electrical components, water circulation or the wider heating system.
Some issues may be relatively straightforward to resolve, while others require specialist equipment, replacement components or further assessment.
Refrigerant circuit work must be carried out by appropriately qualified professionals. Electrical work should also be undertaken by a suitably competent person.
If your heat pump has stopped working, record any error codes and note when the problem started. Avoid opening the equipment casing or attempting repairs yourself.

How to Look After Your Heat Pump Between Services
There are a few simple steps homeowners can take to help maintain their system between professional inspections.
Keep the outdoor unit clear
Remove loose leaves and debris from the surrounding area, ensuring there is sufficient space for airflow. Follow the manufacturer's guidance and do not remove protective panels.
Check your heating controls
Make sure your schedule and temperature settings reflect how you use your home. Avoid making frequent, unnecessary changes without understanding how your particular heat pump responds.
Pay attention to changes
Unusual noises, recurring warning messages, water leaks or a noticeable drop in heating performance can all justify further investigation.
Follow the manufacturer's maintenance advice
Recommended service intervals and homeowner checks vary by model, so use the guidance supplied with your equipment.
Do not interfere with internal components
Electrical parts, refrigerant circuits and internal mechanical components should be left to appropriately qualified professionals.
These steps are not a substitute for professional servicing, but they can help you recognise potential issues and provide useful information when arranging assistance.

FAQs About Heat Pump Servicing and Repairs
How often should an air source heat pump be serviced?
The recommended interval depends on the manufacturer, model, installation and warranty requirements. Check your system documentation and follow the manufacturer's maintenance recommendations. A qualified service provider can advise on an appropriate schedule.
Why has my heat pump stopped heating my home?
Possible causes include incorrect settings, an airflow restriction, a system fault or a problem affecting heat circulation. Check the controls and any error messages first. If the issue persists, arrange an assessment by a suitably qualified technician.
Can a heat pump be repaired instead of replaced?
Many faults can be repaired, depending on their cause, the condition of the equipment and the availability of suitable replacement parts. A proper diagnosis is needed before deciding whether repair or replacement is the most practical option.
Is it normal for an air source heat pump to make noise?
Yes. Fans and compressors produce some noise during normal operation. However, new grinding, persistent rattling or unusually loud vibration should be investigated, especially if accompanied by reduced performance or warning messages.
Can I service my heat pump myself?
Homeowners can carry out basic external checks permitted by the manufacturer, such as keeping the surrounding area clear of debris. Internal inspections, electrical work and refrigerant-related work should be left to appropriately qualified professionals.
