Heat pump repairs in Dungiven: what to expect
Whoever installed your heat pump, aftercare can be arranged in Dungiven. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
Repairs in Dungiven that need a part ordered are explained and priced before the engineer leaves. Across Dungiven and County Londonderry, 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 pumps installed by another company that need a second opinion
- Systems losing pressure or needing frequent topping up
- Rooms or hot water not getting warm enough
What's included
- Supply and fitting of replacement parts
- A clear explanation of the fault and a price for the repair before work goes ahead
- System refill, venting and recommissioning after the repair
- Fault-finding visit at a rate agreed before attending
- Testing of sensors, pumps, valves, pressures and electrics
For repeated faults in Dungiven, the engineer looks at the system design as well as the failed part.
Grants and rules for heat pumps in Northern Ireland
The Boiler Upgrade Scheme covers England and Wales only, and there is currently no dedicated heat pump grant for homeowners in Northern Ireland. Our quote for a Dungiven home is therefore shown without a grant deduction; if support becomes available we will tell you how it applies.

Heat pump repairs in Dungiven: questions
Do you also cover Limavady?
Yes. We arrange heat pump servicing and repairs in Limavady, which is about 9 miles north of Dungiven, and across County Londonderry.
How often should a heat pump in Dungiven 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.
Will the engineer need access indoors as well as outside?
Usually yes. The outdoor unit, the hot water cylinder, the controls and the pipework and valves indoors are all part of the visit, so allow access to each.
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.
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.
