What to know about heat pump repairs in Trowbridge
Aftercare matters as much as installation. For a heat pump in Trowbridge 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.
We repair heat pumps in Trowbridge whoever installed them, including older monobloc and split systems. Outdoor units in exposed spots around Trowbridge can ice more heavily, so siting is checked as part of any icing fault.
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.
- Outdoor units that have become noisy, iced up or keep switching on and off
- Heat pumps installed by another company that need a second opinion
- Rooms or hot water not getting warm enough
What's included
- A clear explanation of the fault and a price for the repair before work goes ahead
- Supply and fitting of replacement parts
- Testing of sensors, pumps, valves, pressures and electrics
- Fault-finding visit at a rate agreed before attending
- Refrigerant repairs by an F-gas certified engineer where needed
Repairs in Trowbridge that need a part ordered are explained and priced before the engineer leaves.

Heat pump repairs in Trowbridge: questions
Do you also cover Bradford-on-Avon?
Yes. We arrange heat pump servicing and repairs in Bradford-on-Avon, which is about 3 miles north-west of Trowbridge, and across Wiltshire.
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.
How often should a heat pump in Trowbridge 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.
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.
How much does a heat pump repair cost?
Heat pump repairs have a typical range of £90–£1,100, including VAT, depending on the part and labour involved. Sensor replacements sit at the lower end, while control boards and refrigerant repairs on split systems sit higher. Every repair starts with a fault-finding visit, with a guide price of £90–£180 for the first hour, and the repair is priced before work goes ahead.
