Before you book: heat pump repairs in Ealing
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.
We repair heat pumps in Ealing whoever installed them, including older monobloc and split systems. For repeated faults in Ealing, 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
- Outdoor units that have become noisy, iced up or keep switching on and off
- Rooms or hot water not getting warm enough
What's included
- Reading of error history and operating data
- Refrigerant repairs by an F-gas certified engineer where needed
- System refill, venting and recommissioning after the repair
- Fault-finding visit at a rate agreed before attending
- Testing of sensors, pumps, valves, pressures and electrics
Heat pump owners in Ealing can arrange a fault-finding visit at a rate agreed before an engineer attends.

Heat pump repairs in Ealing: questions
How often should a heat pump in Ealing 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 Ealing that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Ealing, whoever fitted them. Tell us the make and model when you get in touch.
What should I check before booking a visit in Ealing?
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.
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.
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.
