Questions from Clapham
Is there an emergency air con repair line for Clapham?
Yes: ring the emergency line, day or night, from anywhere in Clapham. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
Can I get a fixed-price quote for air conditioning repair in Clapham?
Use the quote form, or email, with a description of the job. Straightforward work can be priced remotely. Bigger jobs get a survey and a written fixed price.
Which manufacturers do you install and repair?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and explain why.
Do I need to service the system to keep the warranty?
It can, for some brands. Send us the make and model and we’ll tell you what the manufacturer expects, and book the service at the interval they recommend.
Why is my air conditioning blowing warm air?
It can be anything from a dirty filter to a refrigerant leak. We read any fault code and test the system to find which, then give you a fixed price to fix it.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
Can you repair an R22 air conditioning system?
R22 is an ozone-depleting refrigerant, and new R22 cannot be used for servicing. Some non-refrigerant faults can be repaired if parts are available, but a refrigerant leak normally means replacement. We explain the options and quote for a new system if that is the answer.
Air conditioning repair in Clapham
Wondering whether the fault is something simple? A quick check of the filter, settings and remote can rule out the simple causes, then ring us on 07833 053749 or write to us at info@aircondoctor.co.uk if the problem is still there. You will hear back from us the same working day. If the problem is frost on the pipework and a unit blowing warm air, we can help.
Air conditioning repairs in Clapham are often in flats, offices and shops, with outdoor units on balconies, rear walls or flat roofs. Telling us where the outdoor unit is and how we reach it saves time on the visit.
Warranty periods vary by brand and by product. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

Aftercare tips
Aftercare is straightforward, and it makes the next visit easier:
- If there’s ice on the pipes, switch off and let it melt
- Keep to the service interval the manufacturer recommends
- Check the filter, the mode and the set temperature before calling us
Keep the filters clean and the outdoor unit clear after the repair: clean filters every few weeks in heavy use and space around the outdoor unit. An annual service is the best way to catch the next fault before it stops the system.
Filter cleaning is the simplest prevention there is. Clogged filters starve the unit of air, and that can cause ice, drips and poor performance, so keep them clean as the manual describes.
Safe owner checks
On air conditioning, the filters in the indoor unit are usually the one part owners can clean where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.
How it works
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First comes a careful look at the system or the space, then we do the work, and finally everything is tested, recorded and explained. The middle part takes longest, which takes anything from an hour or so to a full day, depending on the fault and the parts. Let us know who controls access to the building in Clapham, as that saves time on the day.
- First the diagnosis: fault codes read, electrics and airflow checked, drain and refrigerant tested.
- Next, a plain explanation and a fixed price.
- Where a repair does not make sense, you’ll hear it from us, with the alternatives.
- Then the fix, with leaks repaired before any refrigerant is added.
- Sign off: prove it works and record the visit.
Before we arrive
- Mention any managing agent or landlord rules we need to follow
- Unlock any gate, garage or side passage we need
- Tell us about access, such as roof hatches, high walls or locked plant areas
Ask for a quote
Here’s what helps us quote: the address and the type of property, photos of the rooms or units, the make and model of any existing system and any symptoms, from error codes to drips. Once you have those, phone 07833 053749.
Advice
What a repair looks like in Clapham
Clapham’s centre falls inside the Rectory Grove Conservation Area. Draw a one-mile circle round the middle of Clapham and it takes in 16 conservation areas. Church of St Paul, listed at grade II*, is one of roughly 129 protected buildings and structures in the half-mile around Clapham’s centre. That only matters for replacements, where a new outdoor unit on a protected building can need consent. VOA council tax data put about 45% of homes in and around Clapham before 1919, and about 80% of households live in flats, according to the last census (2021). In flats, outdoor units are often on balconies, roofs or high walls, so tell us how we reach yours. London repairs often depend on reaching the outdoor unit, so access details help us plan.
