West Sussex · Air conditioning repair
West Dean air conditioning repair
One call covers fault finding and repair for split, multi-split, ducted, cassette and VRF air conditioning, whatever the brand in West Dean, from the first look to sign-off. F-Gas certified, NICEIC approved and Checkatrade members.
- Poor airflow even with clean filters
- Air conditioning running but not cooling
- New noises from the system
Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Do not keep resetting a breaker that trips
- Book an annual service after the repair
- Send us a photo of any code on the display
Keep the filters clean and the outdoor unit clear after the repair: clean filters every few weeks in heavy use and space around the outdoor unit. A yearly service catches problems before they become breakdowns.
Small changes are worth acting on. A drip, a new noise, a weaker airflow or an occasional error code is often the first sign of a fault and catching it early keeps the repair simpler.
How we handle air conditioning repair in West Dean
Think of it as a doctor’s appointment for your air conditioning: diagnose the cause, treat it properly and sign it off when it’s working. Guessing is expensive, and topping up refrigerant on a system with a blocked filter fixes nothing. We are often asked to deal with a unit that won’t start and weak airflow from the indoor unit, across VRF systems, ceiling cassettes and ducted systems.
A visit to West Dean is planned so we can usually finish in one go, unless a part has to come from the manufacturer.
We’re an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Air conditioning repair around West Dean
About 71% of households live in detached or semi-detached houses, according to the 2021 Census. Tell us where your outdoor unit is and how to reach it, so we can plan the visit. The centre of West Dean lies within the West Dean Conservation Area. Listed buildings are part of the picture here: about 33 within half a mile of the centre, such as The Parish Church of St Andrew (grade II*). 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.
Schools such as West Dean CofE Primary School can report a fault on the 24/7 line and have non-urgent work done out of term.

What we are called out for in West Dean
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 the code is a starting point, not the answer. Common causes include sensors, wiring between the units and the circuit boards.
What we’re most often called about:
- A flashing light and a system that will not run
- Weak airflow from the indoor unit
- A noisy indoor or outdoor unit
If the display shows a code, write it down: it helps narrow down the fault.
What your quote should include
- How VAT is shown, and which rate applies
- How extra work would be agreed if they find something unexpected
- If the quote is based on a survey, pictures or a diagnosis
The process
We book the visit for a day and time that suit you, and we let you know if plans need to move. On arrival, the engineer compares the job with the survey, your pictures or the details you gave us. Anything unexpected is raised with you before we go further. After that, it takes as long as the fault needs, from a quick fix to a return visit for parts. Seeing the property in photos first means the trip to West Dean can be planned properly.
- Diagnose: test the system until the cause is clear.
- 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.
- The sign-off: the system tested in operation and the work recorded.
How to prepare
- Let us know where we can park and unload
- Name a contact who can meet us at the agreed time
- Clear the space around the indoor unit, or where it will go

Related advice
System by system
Multi-split systems
A multi-split links several indoor units to one outdoor unit, so a fault outside can affect every room, while a fault inside may affect only one. That shapes the diagnosis and the repair.
Wall-mounted split systems
On a wall-mounted split, the indoor and outdoor units talk to each other through a control cable. A break in that communication usually brings up an error code, and we test the cable, the boards and the connections to find the cause.
West Dean questions
Is West Dean in your area for air conditioning repair?
Yes. We work across London and the South East from our base in East Grinstead, and West Dean is part of that. Tell us a little about the job and we will take it from there.
Do you cover smaller places like West Dean?
Yes, smaller places are covered as well as towns. Send a few details and photos, and we reply the same working day.
How do you keep the place clean during the work?
We start with protection: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
How long does the work take?
It depends on the job, but most of the time it takes a single visit for many faults, while some repairs need a second visit once parts arrive. We’ll confirm it with the quote.
Do you work on commercial properties?
Yes. From one rented home to commercial buildings, we work the same way: a look first, a fixed-price quote and written records.
What causes ice on the indoor coil?
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 isn’t it, we will find the cause.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey tells us what the job needs and how to do it, and the quote is based on that.
What a customer said
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
