Before you book: heat pump servicing in Mumbles
Aftercare matters as much as installation. For a heat pump in Mumbles 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.
Service visits in Mumbles include unvented cylinder safety checks alongside the heat pump itself. If a heat pump in Mumbles has not been serviced for a while, the first visit includes a full check of settings and pressures.
An annual service keeps a heat pump running efficiently, catches small faults early and is often a condition of the manufacturer's warranty.
- Systems where the manufacturer's warranty requires annual servicing
- Heat pumps a year or more past installation
- Landlords who need dated service records for each property
What's included
