- Rooms or hot water not getting warm enough
- Systems losing pressure or needing frequent topping up
- Heat pumps installed by another company that need a second opinion
What's included
- Testing of sensors, pumps, valves, pressures and electrics
- Reading of error history and operating data
- A clear explanation of the fault and a price for the repair before work goes ahead
- Refrigerant repairs by an F-gas certified engineer where needed
- Supply and fitting of replacement parts
Repairs in Builth Wells that need a part ordered are explained and priced before the engineer leaves.

Heat pump repairs in Builth Wells: questions
How much does a visit cost in Builth Wells?
The rate for a service or fault-finding visit is agreed before anyone attends. Any repair is priced in writing before parts are ordered, so you decide before work goes ahead.
How often should a heat pump in Builth Wells 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.
What should I check before booking a visit in Builth Wells?
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.
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.
Why is my heat pump showing an error code?
An error code is the heat pump's way of reporting a problem it has detected, such as low water flow, a sensor reading out of range or a communication fault between units. Note the code and check the manual, as some codes clear after a simple reset or pressure top-up. If it returns, an engineer can trace the underlying cause.
