When an air source heat pump stops working, the house can cool down quickly, hot water can run short, and the fault code on the controller often raises more questions than it answers. The best next step is simple: get calm, practical help from an engineer who understands the system and can attend quickly.

When an air source heat pump breakdown needs urgent attention
Some heat pump problems are inconvenient. Others need a fast call out because they can leave the property without heating or hot water. If the system has stopped running completely, is repeatedly tripping the electrics, or is showing a fault that will not clear, it is time to call an engineer.
A breakdown can show up in several ways:
No heating from radiators or underfloor heating
No hot water from the cylinder
The outdoor unit is not running
The fan is not moving
The unit keeps starting and stopping
The controller shows an error code
The system pressure is too low
The electrics trip when the heat pump starts
Unusual noises come from the outdoor unit
Ice builds up and does not clear during normal defrost cycles
If you are unsure what the fault means, do not keep resetting the system again and again. Repeated resets can hide useful fault history and may put extra strain on the equipment. A quick phone call to Igloo Heating can help you decide whether the issue needs an emergency visit or a planned repair.
Local breakdown help across Dorset and Hampshire
Igloo Heating supports homeowners and landlords who need an air source heat pump breakdown service in Dorset and surrounding areas. That includes Poole, Christchurch, Bournemouth, Ringwood, Southampton, wider Dorset, and parts of Hampshire.
Local attendance matters because heat pump faults often need more than a remote guess. The engineer may need to check the outdoor unit, controls, wiring, system pressure, circulation pumps, valves, filters, and the hot water cylinder. Being within reach helps keep waiting times down and gives customers a more practical route to repair.
For many common faults, Igloo Heating can generally fix the problem the same day. This can depend on the fault, the make and model of the heat pump, and whether specialist parts are needed. Even when a part has to be ordered, a proper diagnosis helps avoid wasted time and guesswork.
Igloo Heating is also Gas Safe registered, which is useful for homes with mixed heating systems, boilers, cylinders, or wider heating work. Gas Safe registration matters for gas appliances and gives customers confidence that the company works to recognised safety standards.
What to check before calling an engineer
A few simple checks can sometimes identify an obvious issue. These checks should be safe and non-invasive. Do not remove covers, open electrical panels, or attempt refrigerant work. Air source heat pumps combine water, electrics, controls, and refrigeration circuits, so deeper investigation should be left to a qualified engineer.
Before calling, you can check:
The controller display
Look for a fault code or warning message. Write it down or take a photo before pressing anything.
The power supply
Check whether the controller is on and whether any obvious switches have been turned off by accident.
The heating schedule
Make sure the system has not been set to holiday mode, frost protection only, or a reduced temperature.
The room thermostat
Raise the set temperature and see whether the system responds.
The hot water setting
If the problem is hot water only, check whether the hot water schedule is active.
The system pressure
If your system has a pressure gauge, note the reading. Low pressure can stop the system from running properly.
Visible ice or debris around the outdoor unit
Leaves, blocked airflow, or heavy ice can affect performance. Do not pour boiling water on the unit or chip ice away with tools.
These checks can help the engineer understand the fault faster. They can also help Igloo Heating give better advice over the phone.

Why air source heat pumps can stop working
Air source heat pumps are reliable when installed, commissioned, and maintained correctly. Like any heating system, they can still develop faults. Some are caused by wear and tear. Others come from water pressure issues, blocked filters, control settings, frozen components, or electrical problems.
Common causes include:
Low system pressure or a small leak
Air trapped in the heating circuit
Blocked strainers or filters
Faulty circulation pumps
Motorised valve problems
Sensor faults
Control or thermostat faults
Defrost issues
Frozen condensate or drainage problems
Electrical faults
Poor airflow around the outdoor unit
Problems linked to the hot water cylinder or immersion backup
Some faults are quick to repair. A blocked filter, incorrect setting, or failed sensor can often be handled without major disruption. Other faults need replacement parts or more detailed testing.
A good engineer will not just clear the error code and leave. They will look for the reason behind the fault, test the system, and make sure it is running safely before handing it back.
What happens during a breakdown visit
A professional breakdown visit should be methodical. Igloo Heating will usually start by listening to what has happened, when the problem began, and whether anything changed recently. For example, a power cut, plumbing work, freezing weather, or a recent service can all give clues.
The engineer may then check:
Fault codes and system history
Outdoor unit operation
Water pressure and flow
Filters, strainers, and visible pipework
Pumps, valves, and expansion vessel condition
Thermostats and heating controls
Hot water cylinder controls
Electrical supply and safety where required
Signs of leaks, freezing, or poor circulation
The aim is to get the heating and hot water working again as quickly as possible while avoiding rushed repairs that cause repeat call outs. If the fault can be fixed there and then, the engineer will normally do so. If a part is required, they can advise on the next step and keep the repair moving.
Why same day repair is often possible
Many heat pump breakdowns come from parts and issues that heating engineers deal with every week. Controls, pumps, valves, pressure problems, filters, and settings can often be handled during the first visit. That is why Igloo Heating can generally fix most faults the same day.
Same day repair depends on a few practical points:
The fault can be diagnosed safely
The system is accessible
Required parts are available
The unit has not suffered major component failure
The system pipework and electrics are in suitable condition
The fault is not caused by a larger installation issue
Even when the repair is not completed immediately, a same day diagnosis still matters. It can confirm whether the system is safe, whether backup heat is available, and what part or work is needed next.

Do not ignore small warning signs
A heat pump rarely fails at a convenient time. Small problems can become bigger ones if the system keeps running under strain. If the property is still warm but the unit sounds louder than usual, takes longer to heat the cylinder, or shows intermittent warnings, it is worth getting it checked.
Early attention can help prevent:
Loss of heating during cold weather
Repeated electrical trips
Higher running costs from poor performance
Strain on pumps and valves
Damage from freezing or poor circulation
Emergency disruption for tenants or family members
Landlords should take warning signs seriously too. A reliable heating system is part of keeping a property comfortable and safe. Fast attendance can reduce tenant stress and help avoid repeat complaints.
Safety matters with heat pump repairs
Homeowners can check settings, schedules, and visible issues, but deeper repair work should be carried out by a competent engineer. Heat pump systems involve electrical components, sealed refrigeration circuits, unvented hot water cylinders in many homes, and pressurised heating circuits.
Avoid:
Opening electrical covers
Bypassing safety controls
Taping down switches or sensors
Repeatedly resetting a tripping circuit
Attempting refrigerant repairs
Changing system pressure without knowing the correct process
Removing panels from the outdoor unit
If you smell burning, see signs of electrical damage, or the system is tripping the electrics, switch it off if safe to do so and call for help. For dangerous electrical situations, contact the relevant emergency service or electricity network operator.
Igloo Heating’s combination of heat pump fault finding experience and Gas Safe registration gives customers a single, reliable contact for heating support across the local area.
