- Poor airflow even with clean filters
- Ice on the pipework or the coil
Why it’s worth doing now in South Kensington
Small faults rarely stay small. A blocked drain becomes water damage, and a slow leak drains the refrigerant until the compressor is working far harder than it should and early diagnosis normally keeps the repair simpler. Consents in London blocks can take time, which is another reason to plan the job in South Kensington early.
Leaving a fault or an overdue service rarely makes the work cheaper. Small problems, from blocked filters to slow leaks, tend to get worse, and a struggling system uses more electricity to do less. If you’re not sure what’s needed, call us on 07833 053749 or use the quote form for straight advice and a fixed price.

How we handle air conditioning repair in South Kensington
When air conditioning stops cooling, leaks water or shows an error code, the symptom rarely tells you the cause. Warm air can mean anything from a dirty filter to a sensor, board or refrigerant fault, so we diagnose before we repair. If you are dealing with ice on the pipework or the coil and a flashing light and a system that won’t run, we can sort it out.
Many buildings in South Kensington have a managing agent or security desk, so tell us who controls access. Roof access can need keys or permits, and we plan for that before we arrive.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Questions from South Kensington
How do I get a quote for air conditioning repair in South Kensington?
The easiest way is to ring us on 07833 053749 or write to us at info@aircondoctor.co.uk with a few details and photos. Simple jobs can be priced from pictures; otherwise we arrange a site survey and then give you a fixed-price quote.
Do you cover South Kensington for air conditioning repair?
Yes. South Kensington is one of the places we cover. To start, phone us on 07833 053749 or use the quote form with a few photos.
Who has to arrange F-Gas leak checks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Why is water dripping from my indoor unit?
Typically a blocked or kinked condensate drain, a failed condensate pump or a unit that isn’t level. Ice on the coil from low airflow or low refrigerant can also melt and drip. Turn it off and call us on 07833 053749 or use the quote form.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine from all the leading brands. Tell us the make and model and send any paperwork you have.
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.
Why is my air conditioning blowing warm air?
There are several possible causes, from simple to serious. We read any fault code and test the system to find which and you get a fixed price before the repair.
How the visit works
The visit goes in the diary at a time that works for you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the photos you sent. If something is different, we talk it through with you before carrying on. From there, the work takes anything from an hour or so to a full day, depending on the fault and the parts. If a freeholder or agent needs to agree the work in South Kensington, we can send them the details.
- Diagnosis comes first: codes, electrics, airflow, drain and refrigerant.
- 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.
- Then the fix, with leaks repaired before any refrigerant is added.
- Finally, a check that it’s working and a record of what we did.
Preparing for the visit
- Unlock any gate, garage or side passage we need
- Tell us about parking and loading
- Keep pets out of the rooms we’re working in

Related advice
Before you call an engineer
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
