Not cooling or heating
Poor output can relate to airflow, settings, sensors, refrigerant-side issues or other electrical and mechanical faults.

Practical fault finding for systems that are noisy, leaking or no longer cooling properly.
A considered approach
Good fault finding starts with the symptom, then tests the likely causes.
Practical fault finding for systems that are noisy, leaking or no longer cooling properly.
Loss of cooling is only one reason to request a repair. Water around an indoor unit, unusual noise, repeated stopping, poor airflow, unwanted smells, error codes or a system that no longer heats correctly can all indicate that investigation is needed. The same symptom can have more than one cause, so diagnosis should come before assumptions about parts.
Useful information can shorten the first conversation: the equipment make and model, any displayed error code, when the problem began, whether it affects every indoor unit and what happens when the system is restarted. Photographs can help identify the equipment, although they cannot replace testing where a technical fault is involved.
The practical repair options depend on the diagnosis, age and condition of the system, access, and whether compatible parts remain available. Where repair is not sensible, the reasons and replacement choices should be set out clearly rather than presenting replacement as the automatic first answer.
What matters
Common reasons to arrange fault finding.
Switch the equipment off and seek advice if it appears unsafe, is leaking near electrical equipment or is behaving unpredictably.
Water or drainage problems
Leaks and overflowing condensate need investigation to identify blockages, installation issues or damaged components.
Noise, smells or error codes
Changes in sound, odour or displayed warnings provide useful clues but still require systematic diagnosis.
How it works
A repair decision based on evidence.
A clear sequence makes it easier to understand the recommendation, scope and next decision.
1. Describe the fault
Provide the model, symptoms, error code, affected rooms and any recent changes to the system.
2. Inspect and diagnose
Check the relevant equipment and operation to narrow down the underlying cause.
3. Review the options
Explain the finding, likely parts or work, equipment condition and whether repair appears economical.
4. Repair and retest
Complete authorised work where practical, then test operation and explain any further recommendation.
Frequently asked questions
Useful answers about air conditioning repairs.
If you want to discuss your own system or property, call 01622 534131.
Should I keep using a leaking air-conditioning unit?
It is sensible to stop the affected equipment and request advice, particularly where water is near electrics, finishes or furniture. Continued operation may cause additional damage.
Does an error code identify the exact failed part?
Not always. A code can indicate the circuit or condition that needs investigation, but further checks may be needed before deciding which component or underlying issue is responsible.
Can every older system be repaired?
Not necessarily. Parts availability, refrigerant type, overall condition and the cost of repair all matter. An assessment should compare a realistic repair with replacement where appropriate.
Can refrigerant simply be topped up?
A loss of refrigerant indicates that the sealed system needs proper investigation. Adding refrigerant without addressing the reason for the loss is not a complete repair.
