About our air conditioning repair in Shermanbury
When air conditioning stops cooling, leaks water or shows an error code, the symptom rarely tells you the cause. A unit blowing warm air might have a blocked filter, a failed sensor, a fault on the circuit board or a refrigerant leak, which is why diagnosis comes first. The work covers ducted systems, VRF systems and wall-mounted split systems, and people most often call us about a unit that barely blows any air and a unit that won’t start.
Around Shermanbury, outdoor units often sit close to gardens and hedges, so leaves, seeds and cobwebs on the coil are worth checking first.
Nothing is signed off by word of mouth: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual, because it helps with any later warranty question.

Looking after your system
Simple habits make a real difference. Our advice:
- Note any error code, or take a photo of the display
- Turn it off and let ice clear before the visit
- Stop the unit if water is coming through a ceiling
After the repair, the system is run and checked in every mode it has. We confirm it’s working properly and look for anything else that needs attention and point out anything else we spotted.
Sensible use helps. Moderate settings and a closed room mean less strain, so it isn’t running flat out all day.
What air conditioning won’t do
In fairness, there are a few things this work will not fix:
- No power to the building at all
- A system that was undersized for the room in the first place (that needs a bigger system, not a repair)
- Heat gains the system was never designed for
If you’re not sure, just call us on 07833 053749, or email if that’s easier and we will give you a straight answer.

What a repair looks like in Shermanbury
About 74% of households live in detached or semi-detached houses, according to Census 2021 figures. Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day. Historic England lists about 6 buildings and structures within half a mile of the centre of Shermanbury, including The Gateway and Porters Lodge (grade I). Day-to-day work on an existing system isn’t affected; a replacement outdoor unit on a protected building might be.
For a school like Jolesfield CofE Primary School, urgent repairs can be booked straight away and bigger work in the holidays.

How the visit works
The work area is kept tidy throughout, with dust sheets down and offcuts and packaging cleared up. Any holes, fixings or cable routes are agreed with you before we drill. On site, it takes as long as the fault needs, from a quick fix to a return visit for parts. Somewhere like Shermanbury, it helps to know about lanes, gates and where to park.
- First the diagnosis: fault codes read, electrics and airflow checked, drain and refrigerant tested.
- Then the prescription: what’s wrong and what it will cost to put right.
- If the repair is not worth doing, we say so and explain the options.
- The treatment: the repair itself, with any leak found and fixed before recharging.
- Sign off: prove it works and record the visit.
How to prepare
- Dig out any previous service or F-Gas records
- Make sure someone can let us in at the agreed time
- Keep pets out of the rooms we’re working in

What else we do in Shermanbury
Shermanbury: your questions answered
Can you do air conditioning repair in Shermanbury?
Yes, Shermanbury is within the area we cover. To start, call 07833 053749 with a few photos.
Do you cover smaller places like Shermanbury?
Yes. Shermanbury 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.
Why use an F-Gas certified company?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. It’s worth checking before booking and we’ll gladly show you ours.
What accreditations do you have?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Is there a survey before the work?
Yes, every time. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need, and the quote is based on that.
Can I do any of the installation myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is recorded, with F-Gas records where refrigerant work is involved.
When to call us in Shermanbury
Ice on the pipework or the indoor coil is a symptom, not the fault. Low airflow from blocked filters or a failing fan, or low refrigerant from a leak, are the common causes. Switch the system off and let it thaw before calling us.
The things we are asked about most are:
- Ice forming on the indoor unit or pipes
- A system that keeps cutting out
- Water leaking from the unit or through the ceiling
Before you call, note what the unit is doing and any code on the controller.
Before you book anyone
- How extra work would be agreed if they find something unexpected
- What records you get at the end
- If the figure could change on the day
