Air Source Heat Pump Servicing

If your air source heat pump is noisy, cycling often or failing to heat the home properly, we’ll inspect the system, identify the fault and explain the work needed. Contact us to arrange a service visit and understand what needs doing.

Keep It Running

Older property? We service noisy, inefficient or unreliable heat pumps, checking controls, filters and performance so heating works properly again.

What the Service Includes

Routine servicing suits homeowners who want faults found before they affect comfort. A repair visit addresses warning codes, poor heat output or unusual sounds. We work on existing domestic air source heat pump systems.

After assessing the system, we explain remedial work separately and provide a written quotation before chargeable work starts, so you can choose the next step.

Routine System Checks

If your heat pump needs planned maintenance, we inspect the outdoor unit, pipework, electrical connections and controls for signs of wear or damage.

Older Homes Considered

If your property has solid walls, older radiators or an unusual layout, we assess how the heat pump is operating within the existing heating system.

Fault Finding

If the system shows a warning code, makes unusual sounds or cycles too often, we investigate the cause rather than simply resetting it.

Safe Electrical Checks

If an electrical fault affects the heat pump, our NICEIC-registered electricians can check the relevant connections and explain any remedial work.

Clear Next Steps

If the inspection finds a repair or upgrade is needed, we explain the work and provide a written quotation before chargeable work starts.

Clear Findings and Practical Next Steps

During servicing, we examine the outdoor unit, controls, water pressure, electrical connections and condensate route. We test operation across heating and hot water modes, record relevant findings and flag maintenance or repair needs before they become larger faults.

Outdoor Unit and Airflow Checks

If the outdoor unit is icing up, noisy or struggling to heat, we check the fan, coil, airflow and visible pipe insulation. This helps identify restrictions and faults affecting performance.

Heating Performance Testing

If rooms are taking too long to warm, we test the heat pump under heating and hot water demand. We check how the system responds and explain any performance issue we find.

Controls and Operating Settings

If the system is cycling often or the controls feel confusing, we review the programmer, thermostat and operating settings. We explain any changes needed for steadier heating.

Safe Electrical and Refrigerant Checks

If there is an unusual smell, noise or loss of heating, we inspect the accessible safety-critical parts and connections. We’ll identify when specialist repair work is needed rather than masking the fault.

Service Record and Quotation

After the visit, you receive clear findings and practical next steps. If repairs or replacement parts are needed, we explain the work and provide a written quotation before anything proceeds.

Questions About Air Source Heat Pump Servicing

How often should an air source heat pump be serviced?

Tell us the heat pump’s make, age, symptoms and service history before booking. We’ll confirm access requirements, explain the scope and provide a written quotation detailing costs before work starts.

How much does air source heat pump servicing cost?

Servicing costs depend on the system’s age, accessibility and any repairs needed. We’ll assess those factors, explain recommendations clearly and provide a written price before proceeding, so you can decide.

What does an air source heat pump service include?

Alongside routine checks, we clean accessible components, inspect the defrost cycle and review fault history. If parts or settings need attention, we separate servicing from repairs before recommending any work.

How long does an air source heat pump service take?

The visit length depends on the system’s condition and any issues found. We’ll allow enough time to complete checks properly, discuss findings and identify any repairs without rushing on site.

Can you service a Mitsubishi heat pump?

Yes. We service Mitsubishi Electric air source heat pumps, checking model-specific controls, fault codes and operating settings. Have the model number ready so we can prepare accurately before the visit.

What to Expect from Your Heat Pump Service

If the service identifies work beyond routine maintenance, we explain the fault, its priority and the available options before anything proceeds. You receive a written quotation before work starts, so the cost and scope are clear.

Concerned about disruption or unfinished work? We agree what access is needed, keep the visit focused and work tidily. When the service is complete, we explain what we found and what to monitor next.

Safety comes first

A heat pump fault can involve electrical controls, water pressure or the sealed refrigeration circuit. We carry out the appropriate safety checks before testing the system under load.

Checks before adjustments

If a control setting or component needs attention, we confirm the system is safe to work on first. We don’t make changes that could hide a fault or leave the heat pump operating outside its intended conditions. Any issue needing specialist repair is explained clearly before we recommend the next step.

Noisy or frequent cycling

Repeated starts, unusual sounds or uneven heating can point to a control, flow or sizing issue rather than a simple filter problem. We use the service visit to separate normal operating sounds from faults that need attention.

Finding the cause of poor operation

Your heat pump may be working harder because of restricted flow, incorrect settings, air in the heating circuit or a problem with a sensor. We compare how the system is operating with the condition of the property and controls, then explain which finding matters most. That gives you a clear basis for deciding whether to monitor, adjust or repair the system.

Older homes and existing systems

Older properties often have different heat-loss patterns, radiator arrangements and pipework from newer homes. We take those details into account when assessing how the heat pump is performing.

Service advice for your property

If the heat pump is serving an older or solid-wall home, we look at the practical factors affecting comfort rather than judging the unit in isolation. We can identify signs that emitters, controls or circulation are limiting performance and explain what would improve operation. Where the existing system is sound, we say so rather than recommending unnecessary work.

A clear record after the visit

You should know what was checked and what needs watching after a service. We talk through the findings before leaving and set out any recommended follow-up work.

What you take away

The service outcome is explained in plain terms, including any fault, adjustment or maintenance issue we found. If further work is appropriate, the quotation sets out the proposed scope before it starts. You can then decide what to do with the information, without committing to work that has not been agreed.

To arrange an air source heat pump service, contact us with the system make and model, any fault codes and the symptoms you’ve noticed. That helps us prepare for the visit and focus on the issue affecting your home.

If the system has stopped heating or is making unusual noise, don’t wait for performance to worsen. We’ll help you decide the appropriate next step once we know what the heat pump is doing.
