Air conditioning repair in Green End
Wondering whether the fault is something simple? A quick check of the filter, settings and remote can rule out the simple causes, and if that does not fix it, ring us on 07833 053749 or write to us at info@aircondoctor.co.uk. We reply to enquiries the same working day. The work covers heat pumps, ceiling cassettes and ducted systems, and common reasons people get in touch are water leaking from the unit or through the ceiling and a system that keeps cutting out.
In a village like Green End, most air conditioning we repair is in homes, garden rooms and the occasional pub or village business. A photo of the unit’s label and a description of the fault help us plan.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

What a repair looks like in Green End
Valuation Office Agency council tax records put about 36% of homes in the Green End area before 1919, and the last census (2021) found about 77% of households in detached or semi-detached houses. If the outdoor unit is high up or behind a locked gate, mention it when you book. In the mile around Green End’s centre, 2 conservation areas have been designated. Fir Tree Cottage, listed at grade II, is one of roughly 9 protected buildings and structures in the half-mile around Green End’s centre. If a repair turns into a replacement on a listed building or in a conservation area, we check the planning position before changing the outdoor unit.
The rating label on the unit gives the model number, which helps us bring the right parts. If a system fails at a school such as Sandon Junior Mixed and Infant School, our 24/7 line takes the call, and planned repairs can wait for the holidays.

How the visit works
Think of the visit in three stages: diagnose, treat and sign off. First comes a careful look at the system or the space, then we do the work, and finally everything is tested, recorded and explained. The middle part takes longest, which takes an hour or two to diagnose most faults, with the repair time depending on what we find. Work in Green End is booked in advance at a time that suits you.
- Diagnosis comes first: codes, electrics, airflow, drain and refrigerant.
- Then the prescription: what’s wrong and what it will cost to put right.
- Where a repair does not make sense, you’ll hear it from us, with the alternatives.
- Then the fix, with leaks repaired before any refrigerant is added.
- Sign off: prove it works and record the visit.
How to prepare
- Mention any managing agent or landlord rules we need to follow
- Dig out any previous service or F-Gas records
- Give us access to the outside wall, roof or yard where the outdoor unit sits

Green End questions
Will you come out to Green End?
Yes. Green End is within the area we cover across London and the South East. A few pictures and the postcode are enough to get things started.
Who do I call if my air conditioning fails in Green End out of hours?
Yes. Our 24/7 emergency line covers Green End. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
What causes water to leak from an air conditioning unit?
Most leaks come from a blocked drain, a failed pump or a unit that has dropped out of level. Ice on the coil from low airflow or low refrigerant can also melt and drip. Turn it off and ring us on 07833 053749.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
What does an air con repair cost?
Diagnosis call-outs start from £75 + VAT. When we’ve found the fault, the repair is priced before we do it. The cost depends on the fault, the parts and access to the units.
Why does my air conditioning run but not cool?
Common causes are a blocked filter, the wrong mode or set temperature, an outdoor unit that cannot breathe, a failed sensor or board, or low refrigerant from a leak. Start by checking the filter and the mode, and if that doesn’t fix it, phone us on 07833 053749.
Can I do the refrigerant work myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
What air conditioning repair cannot fix
We won’t sell you work that does not address the problem, so here are the limits:
- A refrigerant fault on an R22 system (new R22 cannot be used for servicing, so replacement is typically the answer)
- A room that overheats because of the building, such as a lack of shading or ventilation (the system may need help, not a repair)
- A supply fault outside the property
If in doubt, ring us on 07833 053749 or email us and we will say what we think.
Where we work
- Ceiling cassettes
- Wall-mounted split systems
- Multi-split systems
- Ducted systems
- Heat pumps
- VRF systems
What happens if it’s left?
A struggling system costs more to run. Poor airflow or low refrigerant means more running time for less effect and the extra work wears the parts faster. Planning ahead for a job in Green End means we can bring everything needed.
A single unit or a whole estate, the quote is built the same way: what needs doing, how we get to it and what it needs. You will have a fixed price before work begins, with VAT shown clearly.
Why book with us

For landlords and property managers
Records are where property maintenance often slips. Every visit is written up, with F-Gas records wherever refrigerant work is involved, ready for a tenant, a buyer or an inspection.
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Tell us who the contact on site is and who should receive the paperwork and we will copy in whoever needs it.
