Air conditioning repair in Tewin Wood
We repair air conditioning on all the main brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. It does not matter who installed it and the make and model help us prepare. The work covers multi-split systems, ducted systems and heat pumps, and common reasons people get in touch are a unit that won’t start and a fault code on the display.
Outdoor units in a place like Tewin Wood can be near hedges and fields, so leaves, seeds and cobwebs on the coil are worth checking first.
Warranty periods vary by brand and by product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

What we are called out for in Tewin Wood
When ice forms on the pipes or coil, something else is wrong. It normally points to poor airflow, such as a clogged filter or a fan problem, or to a refrigerant leak. Turn it off and let the ice melt, then call us.
These are the situations we see most often:
- A fault code on the display
- A system that runs but does not cool the room
- Water dripping from the indoor unit
A photo of the error code and the unit’s rating label helps us plan the repair.

What we do, step by step
Think of the visit in three stages: diagnose, treat and sign off. First we check the system or the space against the plan, then the work itself, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, which 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 Tewin Wood can be planned properly.
- First the diagnosis: fault codes read, electrics and airflow checked, drain and refrigerant tested.
- Prescribe: tell you the cause and the fixed cost of the cure.
- 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.
- The sign-off: the system tested in operation and the work recorded.
Preparing for the visit
- Mention any roof access, ladders or high-level work
- Unlock any gate, garage or side passage we need
- Make sure someone can let us in at the agreed time

Tewin Wood questions
Is there an emergency air con repair line for Tewin Wood?
Yes: ring the emergency line, day or night, from anywhere in Tewin Wood. Have the make, model and error code ready, and we’ll talk you through what happens next.
Do you cover smaller places like Tewin Wood?
Yes. Tewin Wood is within the area we cover across London and the South East. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is the law, not just our preference, and it also matters for the manufacturer’s warranty. We’re happy to quote for the full job, supply to commissioning.
What does an air con repair cost?
The first step is a diagnosis, from £75 + VAT, and then you get a fixed price for the repair. You decide before any repair work starts.
Do you look at the job first?
Yes, every time. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need, and the quote is based on that.
Why use an F-Gas certified company?
The law says any company working on equipment containing F gas has to be certified, and the engineers need their own qualifications. It means the refrigerant in your system is handled legally.
What does the error code on my air conditioning mean?
The code is the system’s own clue to the fault, but testing confirms the cause. Write down the code and turn the unit off if it has stopped, and call 07833 053749 or drop us a line.
Let and managed properties
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We can quote either party, and the paperwork can go to both.
Managing agents often deal with us directly. Tell us the property, the work and the access arrangements and we’ll come back with a fixed-price quote.

Why act early in Tewin Wood
Refrigerant supply is changing. R410A systems can still be repaired legally, though the GB phase-down is making R410A harder and dearer to buy, so for older systems we compare the cost of a repair with a replacement. An early booking makes the visit to Tewin Wood easier to arrange.
The pipe route, the height of the units and how we reach them all affect the cost. Each of those is built into the quote, and the price is fixed before any work starts.

From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
