Air Source Heat Pump Servicing & Maintenance

Air source heat pumps are a reliable heating solution that are relatively low maintenance compared to gas or oil boilers. That said, at Ashford Heat Pumps we recommend that a professional check over by a professional engineer is carried out once per year.

This will keep your system working at peak efficiency for its whole lifespan and will catch any issues that might otherwise cause a problem. It is important to maintain any sustainable heating system to make sure it performs well and has the best efficiency. An unmaintained system can cost more to run than an oil or mains gas fired boiler.

Our routine preventative maintenance contract is designed to provide annual servicing for ASHP owners. Service visits typically include cleaning filters and running tests. We also check over historical alarm logs. If necessary, we adjust the system to optimize the efficiency and performance. There is also an emergency breakdown service for heat pumps that are not functioning.

Additional benefits for maintenance clients include priority over non-contract clients in case of a problem, access 24/7 to our emergency telephone number and lower call rates in cases of system failure. Many minor faults can be identified before they lead to major system failures.

Our engineers have more than a decade’s experience with ASHP systems. They are therefore likely to find the problem when inspecting an installed system. Heat pumps that are not functioning properly are often caused by blocked filters, which can be easily repaired. This assumes that the filters have been installed at the time that the system was installed. The majority of heat pump faults result from poorly or incorrectly designed systems

Checks we carry out as part of an ASHP service

Check and clean the air filter

This is the first step in servicing an air source heat pump. The air filter should be checked regularly and cleaned or replaced as needed to ensure proper airflow and efficiency.

Check and clean the outdoor coil

The outdoor coil should be checked and cleaned to ensure proper heat transfer and efficiency. This can be done by using a soft brush or a coil cleaning solution.

Check and clean the indoor coil

The indoor coil should also be checked and cleaned to ensure proper heat transfer and efficiency. This can likewise be done by using a soft brush or a coil cleaning solution.

Check and clean the condensate drain

The condensate drain should be checked and cleaned to ensure proper drainage and to prevent water damage.

Check and tighten all electrical connections

All electrical connections should be checked and tightened to ensure proper operation and to prevent potential safety hazards.

Check and add refrigerant

The refrigerant level should be checked and topped off as needed to ensure proper operation and efficiency.

Check and calibrate thermostat

The thermostat should be checked and calibrated to ensure accurate temperature control.

Check and lubricate all moving parts

All moving parts should be checked and lubricated as needed to ensure proper operation and to prevent wear and tear.

Check the system for leaks

Check the system for leaks and repair any leaks that are found.

Check operation of domestic hot water tank and pressure relief valves

System expansion vessels to be inspected, and hot water pasteurisation settings checked.

Servicing terms and conditions

Any additional anti-freeze may be needed is not included in the above. This will be quoted at time of works, as it can differ greatly between systems.

Component replacements beyond warranty are not included. Manufacturer and workmanship warranties vary and are valid from the date of commissioning. Please refer to Terms and Conditions in your original purchase.

Additional labour costs for additional work are not include in the standard service cost. Please enquire with the specification of your system for a servicing price.
