About our air conditioning repair in Cores End
A diagnosis call-out is from £75 + VAT. When the cause is found, the repair is priced before anything else is done and nothing goes ahead without your say-so. The work covers VRF systems, ceiling cassettes and heat pumps, and common reasons people get in touch are a fault code on the display and water dripping from the indoor unit.
We plan the trip to Cores End so the repair can be finished in one visit where possible, though some parts have to be ordered from the manufacturer.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Common questions in Cores End
Is Cores End within the area you cover?
Yes. Cores 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.
Can you do air conditioning repair in Cores End?
Yes. We work across London and the South East from our base in East Grinstead, and Cores End is part of that. Get in touch with the details and we reply the same working day.
Can you come out for an emergency air conditioning repair?
Yes. We have a 24/7 emergency line for urgent breakdowns. Call 07833 053749 and tell us the make, the symptoms and any error code, and we’ll agree the next steps with you.
Why is there ice on my air conditioning pipes?
The coil gets too cold when air cannot move across it or when the refrigerant charge is low. Check the filter first and if that is not it, we will find the cause.
Do you look at the job first?
Yes. Every job is looked at first, either on a site survey or from pictures and details for simple jobs. A fixed-price quote follows.
What causes water to leak from an air conditioning unit?
The condensate drain or pump is the usual cause: a blocked pipe, a kinked hose or a failed pump. Switch the unit off to avoid water damage, then call us.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Tell us who should receive the paperwork.
When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- A system that was undersized for the room in the first place (that needs a bigger system, not a repair)
- A unit whose parts are no longer made (replacement may be the only option)
- Heat gains the system was never designed for
If in doubt, give us a ring on 07833 053749 or fill in the contact form and we will say what we think before booking.
What the work covers
- Heat pumps
- Ducted systems
- VRF systems
- Wall-mounted split systems
- Ceiling cassettes
- Multi-split systems
Signs you need air conditioning repair in Cores End
An error code is the unit’s own diagnosis, in shorthand. Each manufacturer uses its own codes, and the same code can have more than one cause, so we read the code and then test to confirm. Common causes include sensors, wiring between the units and the circuit boards.
What we’re most often called about:
- Weak airflow from the indoor unit
- Water dripping from the indoor unit
- An error code or flashing light on the unit
For a home or office near Bourne End station, tell us the make, model and error code when you call, so we can plan the repair.
Before booking anyone
- Proof of F-Gas company certification
- Why the equipment they’re quoting suits the job
- Whether a new circuit is included and who certifies it
What happens if it’s left?
Waiting for hot weather to see whether a fault sorts itself out rarely works. If the system is faulty now, it will be faulty in a heatwave, when you need it most and it’s easier to deal with before you depend on it. Booking before summer means the work in Cores End is done before the hot weather.
Putting several jobs into one visit often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed price.

How the visit works
Each visit runs to the same pattern: agree the plan on site, put the dust sheets down, carry out the job, check the system and talk you through it. On site, the work takes as long as the fault needs, from a quick fix to a return visit for parts. If a lane or gateway near Cores End is tight for a van, let us know and we will plan for it.
- 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 will 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.
Getting ready for the visit
- Find the manual or the paperwork for the system, if you have it
- Clear a path to the units and the space around them
- Name a contact who can meet us at the agreed time
