How we handle air conditioning repair in South Croydon
Refrigerant does not 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. Common call-outs are for a system that runs but doesn’t cool the room and a system that keeps cutting out, across heat pumps, wall-mounted split systems and VRF systems.
London systems in South Croydon often run long hours in summer, which is when weak cooling, leaks and error codes tend to appear. The error code on the display, the make and the model are the most useful things to send us.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

Air conditioning repair around South Croydon
Draw a one-mile circle round the middle of South Croydon and it takes in 3 conservation areas. If a repair turns into a replacement on a listed building or in a conservation area, we check the planning position before changing the outdoor unit. The Valuation Office Agency’s council tax figures put about 52% of homes across South Croydon and its surrounding area before 1919, and the last census (2021) found about 48% of households live in flats. Outdoor units serving flats can be awkward to reach, so let us know where yours is. In London, access to outdoor units on roofs and balconies can need planning, so tell us how to reach yours.
If a system fails at a school such as Purley Oaks Primary School, our 24/7 line takes the call, and planned repairs can wait for the holidays.

Common problems we fix in South Croydon
Most indoor unit leaks come back to the condensate. A blocked or kinked drain, a failed pump or a unit that isn’t level are the usual causes, and ice on the coil that melts can drip too.
The things we’re asked about most include:
- A suspected refrigerant leak
- Rattling, buzzing or grinding noises
- An error code or flashing light on the unit
For a home or office near Sanderstead station, tell us the make, model and error code when you call, so we can plan the repair.

How the visit works
If the system has to be off for part of the visit, we tell you before we start, so you can plan around it. In a business, work can often be done one area at a time. On site, it takes an hour or two to diagnose most faults, with the repair time depending on what we find. Photos of the room and where the outdoor unit could go let us plan most of a visit to South Croydon in advance.
- You describe the fault, the make and any error code, ideally with a photo.
- On the diagnosis visit, the engineer tests the system rather than guessing.
- We explain the cause and give you a fixed price for the repair before any work goes ahead.
- 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
- Plan for pets to be kept clear during the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Let us know if the units are on a roof, a high wall or in a locked area
Getting a price
To help us quote: where the property is and what kind of building it is, photos of the rooms or units, the make and model of any existing system and anything you’ve noticed, such as an error code or a noise. Then ring us on 07833 053749, or email if that’s easier.
Advice
Landlords, agents and facilities managers
Bigger systems bring extra duties: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.
Records are where property maintenance often slips. Each visit is written up, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.
What happens if it’s left?
Leaving a fault seldom makes it go away. A blocked drain becomes water damage, and a slow leak drains the refrigerant until the compressor is working far harder than it should, so getting it looked at early normally means a simpler repair. If a lease or managing agent is involved in South Croydon, start the conversation early.

Common questions in South Croydon
How do I get a quote for air conditioning repair in South Croydon?
The easiest way is to call 07833 053749 or use the quote form with a few details and photos. Simple jobs can be priced from photos; otherwise we arrange a site survey and then give you a fixed-price quote.
Is South Croydon in your area for air conditioning repair?
Yes. South Croydon is one of the places we cover. Just call us on 07833 053749 or drop us a line with a few details.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
Why is not my air con cooling?
There are several possible causes, from simple to serious. Diagnosis confirms the cause and you get a fixed price before the repair.
Can you repair an R22 air conditioning system?
Servicing with new R22 isn’t allowed, because it depletes the ozone layer. A fault that does not involve the refrigerant may still be repairable, depending on parts, but a refrigerant leak normally means replacement. We explain the options and quote for a new system if that is the answer.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.
Will I get records for the system?
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.
