How we handle air conditioning repair in Startop's End
A sealed system shouldn’t lose refrigerant, so a low charge means a leak somewhere. Simply adding gas means it will leak away again. We locate the leak, repair it, test, evacuate and recharge, then record it in the F-Gas records. The work covers multi-split systems, heat pumps and wall-mounted split systems, and the jobs we see most are a system that needs topping up again and a fault code on the display.
We plan the trip to Startop's End so the repair can be finished in one visit where possible, unless a part has to come from the manufacturer.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

Questions from Startop's End
Is there an emergency air con repair line for Startop's End?
Yes. Our 24/7 emergency line covers Startop's End. Have the make, model and error code ready, and we will talk you through what happens next.
Do you cover Startop's End for air conditioning repair?
Yes. We work across London and the South East from our base in East Grinstead, and Startop's End is part of that. Get in touch with the details and we reply the same working day.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we have done.
What causes ice on the indoor coil?
Ice is a symptom of low airflow or low refrigerant. Blocked filters, a failing fan or a leak are the common causes. Turn it off, let the ice melt and phone us on 07833 053749 or email us.
Can I do any of the installation myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is a legal requirement, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
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, and repairs and services get a record of the work.

Listed buildings are part of the picture here: about 21 within half a mile of the centre, such as Church of All Saints (grade II*).

System by system
Circuit boards and sensors
Circuit boards and temperature sensors control how the system runs. Sensor faults can stop the system or confuse it, and boards can fail after a power surge or with age.
Ducted and cassette systems
If water is coming through the ceiling, switch the unit off and call us. A failed pump, a blocked drain or an overflowing tray is typically behind it, and we check all three.
How we price air conditioning repair
Some jobs are bigger than they look, and some smaller. The main factors:
- What kind of system it is
- Access, including height, roofs and ladders
- The condition of any existing system
The pipe route, the height of the units and how we reach them can all change the price. Each of those is built into the quote and give you a fixed price before we start.
What we need to know
Photos and a few facts are often enough to price a simple job. Useful things to send:
- A short video of any fault, such as a noise or a flashing light
- A photo of the consumer unit with the cover closed
- The rating plate or label on any existing unit
The quickest way to a quote is to send pictures: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and simple jobs can often be priced without a visit.
What happens on the day
Each visit runs to the same pattern: agree the plan on site, put the dust sheets down, do the work, test what we’ve done and talk you through it. On site, the work takes an hour or two to diagnose most faults, with the repair time depending on what we find. For a place like Startop's End, the timing is set with you and the travel is our side of the planning.
- You tell us the symptoms, the make and any error code.
- The engineer diagnoses the fault on site, testing rather than guessing.
- The fault is explained simply and the repair priced up front.
- Once agreed, the repair goes ahead.
- We test the system in operation and leave you a note of the fault and the fix.
Preparing for the visit
- Unlock any gate, garage or side passage we need
- Tell us about any building rules, permits or sign-in
- Tell us about access, such as roof hatches, high walls or locked plant areas
