Air source heat pump service, at a fixed price

A heat pump has no flame, so there is no combustion to set up. What it does have is a lot of parts that drift out of their best settings: a water system that loses pressure, a strainer that catches debris, an outdoor coil that collects leaves and grime, and controls that are often set up once at installation and never looked at again.

Heat pumps are very sensitive to these things. A boiler with a slightly blocked filter still gets hot. A heat pump with the same problem runs longer, uses more electricity and can start to short-cycle. An annual service is also usually a condition of the manufacturer’s warranty, so check your warranty terms.

We service the air source heat pumps most commonly fitted in Northern Ireland, including Mitsubishi Ecodan, Daikin Altherma, Samsung, Vaillant aroTHERM, Grant Aerona and Panasonic Aquarea. Tell us the make and model when you book. To confirm: confirm heat pump makes serviced

Book a service, or a repair visit, if you notice any of these:

• Rooms take much longer to warm up than they used to
• Your electricity use has risen with no change in how you heat the house
• The outdoor unit is iced over for long periods and does not clear after a defrost cycle
• New noises from the outdoor unit: rattling, grinding or a fan that sounds unbalanced
• The system pressure gauge has dropped below the level in your handover pack
• The controller shows an error code

Heat pump warranties are often longer than boiler warranties, but most come with conditions: registration with the manufacturer within a set time of installation, and an annual service by a competent engineer, recorded each year. If the installer registered the warranty for you, check the paperwork for the exact service requirement.

If your heat pump was installed under a grant scheme, the scheme terms may also say how it should be maintained. Keep every service record with your handover documents.

Some of the most useful work on a heat pump service is not mechanical. A lot of systems run hotter than they need to, because the flow temperature was set high at installation, or because the controls are being used like a boiler: turned off when you go out and up high when you come back.

During the service we look at how the system is set up against how you live in the house, and explain any changes we suggest. Heat pumps usually work best running steadily at a lower temperature, rather than being switched off and on like a boiler. Where weather compensation is fitted, we check the heating curve is set sensibly for your house and radiators.

• Choose heat pump on the booking form, and tell us the make and model if you know it. It is usually on a label on the outdoor unit.
• See the price and pick a slot. £129, on screen before you give any details.
• Get confirmation by email with the date, the time window and the price.

On the day, your engineer needs access to the outdoor unit, the indoor unit or cylinder, and the controls. Please make sure the area around the outdoor unit is clear.

• Your record. You get a written service record with the readings, what was cleaned and anything that was adjusted. Keep it with your warranty paperwork.
• If we find a fault. We explain it in plain terms and price any repair before work starts. Some faults need manufacturer parts or a manufacturer’s engineer, and we will tell you if that is the case.
• Next year. We remind you before your next service is due.

If your house has a heat pump alongside an oil or gas boiler, we can service both on the same visit. Tell us when you book so we allow the time. To confirm: confirm combined heat pump and boiler visit price
