Fault finding and repair
Air Conditioning Repairs
Not cooling, leaking water, tripping out or flashing an error code? Our F-Gas certified engineers diagnose and repair air conditioning of any age and any brand — domestic splits through to commercial VRF — with emergency call-out available for critical cooling.
Faults we fix every week
Most call-outs come down to a handful of causes, and the majority are repairable on the first visit.
- System runs but doesn't cool — usually low refrigerant from a leak
- Water dripping from the indoor unit — blocked condensate drain or pump
- Error code on the controller — sensor, communication or pressure faults
- Outdoor unit not starting — capacitor, contactor, fan motor or PCB
- Ice on the pipework — airflow restriction or undercharge
- Noise or vibration — fan bearings, loose brackets, compressor mounts
- Tripping the electrics — insulation breakdown or a failing component
Leaks repaired, not just topped up
Refrigerant does not get used up — if it is low, it has leaked. Simply regassing is a false economy and, above the statutory thresholds, not compliant. We trace the leak with electronic detection, nitrogen pressure testing or UV dye, repair the joint or component, evacuate the system properly and recharge to the manufacturer's weighed-in charge.
Parts and older systems
We source parts across all major manufacturers and carry common consumables on the van. Where a system uses obsolete refrigerant such as R22, or the repair cost approaches replacement value, we will say so honestly and quote both options so you can decide.
Emergency cover
Server rooms, comms rooms, commercial kitchens and production areas cannot wait. We offer priority emergency call-out, with contracted maintenance customers going to the front of the queue.
How a repair visit works
- Attend, run the system and read fault history
- Electrical and refrigeration diagnostics
- Explain the fault and the options before proceeding
- Repair on the first visit wherever parts allow
- Leak trace, repair, evacuate and weighed-in recharge
- Re-commission and record performance figures
- Written report on the work carried out
- Recommendations to prevent it recurring

Frequently asked questions
My air conditioning is blowing warm air — what's wrong?
The most common cause is low refrigerant due to a leak, followed by a dirty filter or coil restricting airflow, a failed outdoor fan, or the unit being left in heating mode. Diagnosis takes an engineer with gauges — guessing usually costs more.
Why is my indoor unit leaking water?
Almost always a blocked condensate drain or a failed condensate pump. Left alone it will damage ceilings and plaster, so it is worth attending to quickly. It is a straightforward repair in most cases.
Can you repair any brand?
Yes — Mitsubishi Electric, Daikin, Toshiba, Samsung, Midea, Fujitsu, LG, Panasonic, Haier and others, including systems we did not install.
Is it worth repairing an old system?
Often yes. Where a system runs obsolete R22 refrigerant, has a failed compressor, or the repair approaches the cost of new equipment, we quote both repair and replacement and let you decide.
Do you offer emergency call-out?
Yes, for critical cooling such as server rooms, kitchens and production areas. Maintenance contract customers get priority response.
