Heat pump repairs in Truro: what to expect
A heat pump that is serviced and set up properly keeps running efficiently for many years. Many heat pump faults trace back to settings, low pressure or a worn part rather than the heat pump itself, and those can usually be put right.
Heat pump owners in Truro can arrange a fault-finding visit at a rate agreed before an engineer attends. For repeated faults in Truro, the engineer looks at the system design as well as the failed part.
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.
- Systems losing pressure or needing frequent topping up
- Rooms or hot water not getting warm enough
- Heat pumps showing an error code or fault light
What's included
- Fault-finding visit at a rate agreed before attending
- Testing of sensors, pumps, valves, pressures and electrics
- Supply and fitting of replacement parts
- A clear explanation of the fault and a price for the repair before work goes ahead
- Reading of error history and operating data
Outdoor units in exposed spots around Truro can ice more heavily, so siting is checked as part of any icing fault.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Truro quote.

Designing for Truro's winters
Truro sees roughly 8 hours 02 minutes of daylight in late December against 16 hours 25 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

Heat pump repairs in Truro: questions
How much does a visit cost in Truro?
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.
Do you also cover Falmouth?
Yes. We arrange heat pump servicing and repairs in Falmouth, which is about 8 miles south of Truro, and across Cornwall.
Can you work on a heat pump in Truro that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Truro, whoever fitted them. Tell us the make and model when you get in touch.
Can you repair a heat pump installed by another company?
Yes. We carry out fault-finding and repairs on heat pumps installed by other companies, including monobloc and split systems. Tell us the make, model and approximate age when you get in touch, plus any error code shown. If the system is still under the manufacturer's warranty, it may be quicker to contact the original installer or manufacturer first.
Why does my heat pump keep switching on and off?
Frequent starting and stopping, called short cycling, is usually caused by an oversized heat pump, low water flow, too many zones closing at once or controls set with too narrow a range. It reduces efficiency and wears components. An engineer can check the settings, flow rates and design, and can often improve it with control changes before any parts are needed.
