Questions from Deacon's Hill
Do you cover Deacon's Hill for air conditioning repair?
Yes. We work across London and the South East from our base in East Grinstead, and Deacon's Hill is part of that. To start, call us on 07833 053749 or send an email with a few photos.
Is Deacon's Hill within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
What does the error code on my air conditioning mean?
The code is the system’s own clue to the fault, but it isn’t the whole answer. Note the code and switch the system off if it isn’t working, and phone us on 07833 053749 or use the quote form.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up and F-Gas records kept where they apply.
My system uses R22. Can it be repaired?
Replacement is usually the better answer. R22 can’t be topped up with new gas, and parts for old models are scarce, so we will quote for a modern replacement and explain why.
Do I get paperwork after the visit?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.
Which manufacturers do you install and repair?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Air conditioning repair for homes and businesses in Deacon's Hill
Refrigerant doesn’t get used up, so a low charge means a leak somewhere. Simply adding gas means it will leak away again. We find and fix the leak, pressure test, evacuate and recharge to the manufacturer’s charge, then record it in the F-Gas records. Typical jobs include air conditioning running but not cooling and drips from the indoor unit, across heat pumps, ceiling cassettes and wall-mounted split systems.
A visit to Deacon's Hill is planned so we can usually finish in one go, unless a part has to come from the manufacturer.
The records are your system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

What the work involves, system by system
Refrigerant leaks
Topping up without finding the leak only delays the next breakdown and the gas simply leaks out again. That’s why we repair the leak first.
Circuit boards and sensors
Circuit boards and temperature sensors control how the system runs. A failed sensor can make a unit stop, run oddly or show an error code and boards can fail with age or after electrical problems.
What we are called out for in Deacon's Hill
Water dripping from an indoor unit is usually about the condensate. A blocked or kinked drain, a failed pump or a unit that is not level are the usual causes, while ice that forms on the coil and then melts can also cause drips.
If any of these sounds familiar, it’s worth a diagnosis:
- A system that needs topping up again
- Frost on the pipework
- A unit that won’t start
When cooling fails at a school like Summerswood Primary School, we can time non-urgent repair work around lessons.
What your quote should include
- Whether the price is fixed or an estimate
- Whether the quote shows VAT clearly
- What the manufacturer’s warranty covers and for how long
The process
On the day, we arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. The work itself takes a single visit for many faults, while some repairs need a second visit once parts arrive. Pictures of the space and where the outdoor unit could go let us plan the work in Deacon's Hill.
- Diagnose: test the system until the cause is clear.
- Then the prescription: what’s wrong and what it will cost to put right.
- If the repair isn’t worth doing, we say so and explain the options.
- Treat: carry out the repair, sealing any leak before refrigerant goes back in.
- The sign-off: the system tested in operation and the work recorded.
Preparing for the visit
- Clear access to the fuse board
- Let us know where we can park and unload
- Arrange for someone to be there to let us in
Getting a price
Our prices page gives typical ranges, but your quote is based on your job, because no two buildings, rooms or systems are the same. After a look at the job, by photos or a survey, the price is fixed. To get going, ring us on 07833 053749 or send an email.
