Air conditioning repair in Dunton
Faults on all the leading makes are part of our everyday work, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. It does not matter who installed it, so tell us the make and model if you know it. If the problem is new noises from the system and water leaking from the unit or through the ceiling, we can sort it out.
Outdoor units in a place like Dunton can be near hedges and fields, so leaves, seeds and cobwebs on the coil are worth checking first.

What we do, step by step
Each visit runs to the same pattern: check the plan with you, protect the area, do the work, check the system and talk you through it. On site, the work takes anything from an hour or so to a full day, depending on the fault and the parts. For a place like Dunton, the timing is set with you and the travel is our side of the planning.
- It starts with the symptoms: what the unit is doing, the make and any code on the display.
- We diagnose on site, checking the codes, electrics, airflow, drain and refrigerant pressures.
- Once the cause is found, we explain it and fix the price for the repair.
- With your agreement the part is replaced or the fault put right, and refrigerant work goes in the F-Gas log.
- We run the system, check it’s working properly and note anything else that needs attention.
Before we arrive
- Mention any managing agent or landlord rules we need to follow
- Arrange for someone to be there to let us in
- Mention any parking restrictions near the property

Common problems we fix in Dunton
Error codes are the system telling you it has found a fault. Codes differ by brand, and one code can cover several faults, so we read the code and then test to confirm. Common causes include sensors, wiring between the units and the circuit boards.
Reasons to give us a call include:
- Weak airflow from the indoor unit
- Air conditioning running but not cooling
- A system that keeps cutting out
Weak cooling, water dripping from the indoor unit and error codes are the faults we’re called about most.
What your quote should include
- Whose warranty applies, and on what terms
- The make and model of any parts or equipment being quoted
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
Questions from Dunton
Is there an emergency air con repair line for Dunton?
Yes. Our 24/7 emergency line covers Dunton. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
Is Dunton within the area you cover?
Yes, smaller places are covered as well as towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
What causes ice on the indoor coil?
When airflow drops or refrigerant is lost, the coil gets cold enough to ice. Check the filter first, and if it’s clean, the system needs a diagnosis.
Why is water dripping from my indoor unit?
Typically a blocked or kinked condensate drain, a failed condensate pump or a unit that isn’t level. Ice that forms on the coil and melts can cause drips too. Switch the unit off and ring us on 07833 053749.
What does the error code on my air conditioning mean?
Codes differ by brand, and the same code can cover several faults. Tell us the code, the make and the model and we’ll test the system to confirm the cause.
What does F-Gas certified mean?
Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It’s how you know the refrigerant is being handled legally and safely.
Do you look at the job first?
Yes. For simple jobs, photos and a few details can be enough, while bigger systems and repairs that need testing get a visit.

How the job changes from property to property
Wall-mounted split systems
Wall-mounted splits are the systems we repair most often. Drains, coils, fans, sensors and leaks account for many of the faults, and most are diagnosed on the first visit.
Multi-split systems
On a multi-split, one outdoor unit serves several indoor units, so a fault outside can affect every room, while a fault inside may affect only one. It tells us where to look first.
Air conditioning repair around Dunton
On the National Heritage List, around 6 entries fall within 0.5 miles of the middle of Dunton; Church of St Martin (grade II*) is one. We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that. The Valuation Office Agency’s council tax figures show about 30% of homes across Dunton and its surrounding area were built in 2000 or later, and the 2021 Census found about 84% of households in detached or semi-detached houses. Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day.
The make, model and error code are the most useful things to tell us.
