What to know about heat pump repairs in Cranleigh
Aftercare matters as much as installation. For a heat pump in Cranleigh 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.
Repairs in Cranleigh that need a part ordered are explained and priced before the engineer leaves. We repair heat pumps in Cranleigh whoever installed them, including older monobloc and split systems.
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.
- Rooms or hot water not getting warm enough
- 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
What's included
- Testing of sensors, pumps, valves, pressures and electrics
- Fault-finding visit at a rate agreed before attending
- Supply and fitting of replacement parts
- System refill, venting and recommissioning after the repair
- Reading of error history and operating data
Heat pump owners in Cranleigh can arrange a fault-finding visit at a rate agreed before an engineer attends.
Grants and rules for heat pumps in England

Heat pump repairs in Cranleigh: questions
Do you also cover Godalming?
Yes. We arrange heat pump servicing and repairs in Godalming, which is about 6 miles north-west of Cranleigh, and across Surrey.
How often should a heat pump in Cranleigh 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 work on a heat pump in Cranleigh that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Cranleigh, whoever fitted them. Tell us the make and model when you get in touch.
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.
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.
