Heat pump repairs for Berwick-upon-Tweed homes
Aftercare matters as much as installation. For a heat pump in Berwick-upon-Tweed the visit checks the outdoor unit, the water circuit and the controls, and the engineer explains any settings that would help the system run more efficiently.
For repeated faults in Berwick-upon-Tweed, the engineer looks at the system design as well as the failed part. Across Berwick-upon-Tweed and Northumberland, refrigerant repairs on split systems are carried out by an F-gas certified engineer.
When a heat pump shows an error, loses pressure or stops heating, an engineer diagnoses the cause and explains the repair and its cost before fixing it.

Heat pump repairs in Berwick-upon-Tweed: questions
How often should a heat pump in Berwick-upon-Tweed be serviced?
Once a year is the usual recommendation, and many manufacturers make annual servicing a condition of the warranty. Check your warranty terms for the exact requirement.
Do you also cover Alnwick?
Yes. We arrange heat pump servicing and repairs in Alnwick, which is about 28 miles south-east of Berwick-upon-Tweed, and across Northumberland.
What should I check before booking a visit in Berwick-upon-Tweed?
Note any error code on the controller, check the system pressure gauge if you have one, and make sure the outdoor unit is clear of leaves or snow. Photos of the unit and controller help.
Is ice on my heat pump a fault?
Some frost on the outdoor unit in cold, damp weather is normal, and the unit clears it with regular defrost cycles, often releasing a little vapour. It becomes a fault when thick ice builds up and does not clear, or when ice blocks the fan. That can point to poor airflow, a failed sensor, drainage problems or low refrigerant, and needs checking.
Do refrigerant repairs need a specialist?
Yes. Any work on a heat pump's refrigerant circuit, such as tracing a leak, replacing a component or re-gassing, must by law be done by an F-gas certified engineer where the refrigerant is fluorinated, such as R32; units using R290 (propane) need an engineer trained in flammable refrigerants. On split systems the refrigerant runs through pipes inside your home, so leaks there are more likely than on sealed monobloc units.
