Heat pump repairs in Thame: 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.
Across Thame and Oxfordshire, refrigerant repairs on split systems are carried out by an F-gas certified engineer. Heat pump owners in Thame can arrange a fault-finding visit at a rate agreed before an engineer attends.
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 showing an error code or fault light
- Systems losing pressure or needing frequent topping up
What's included
- System refill, venting and recommissioning after the repair
- A clear explanation of the fault and a price for the repair before work goes ahead
- Reading of error history and operating data
- Supply and fitting of replacement parts
- Fault-finding visit at a rate agreed before attending
Repairs in Thame that need a part ordered are explained and priced before the engineer leaves.
Grants and rules for heat pumps in England
Homes in Thame can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.

Heat pump repairs in Thame: questions
Can you work on a heat pump in Thame that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Thame, whoever fitted them. Tell us the make and model when you get in touch.
How often should a heat pump in Thame 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.
Do you also cover Princes Risborough?
Yes. We arrange heat pump servicing and repairs in Princes Risborough, which is about 6 miles east of Thame, and across Oxfordshire.
Is ice on my heat pump a fault?
Some frost on the outdoor unit in cold, damp weather is normal, and the unit clears it with regular defrost cycles, often releasing a little vapour. It becomes a fault when thick ice builds up and does not clear, or when ice blocks the fan. That can point to poor airflow, a failed sensor, drainage problems or low refrigerant, and needs checking.
Why is my heat pump showing an error code?
An error code is the heat pump's way of reporting a problem it has detected, such as low water flow, a sensor reading out of range or a communication fault between units. Note the code and check the manual, as some codes clear after a simple reset or pressure top-up. If it returns, an engineer can trace the underlying cause.
