How we handle air conditioning repair in London
Our emergency line runs 24/7 for urgent breakdowns, from an overheating comms room to water leaking from a unit. Ring 07833 053749 with the make, what’s happening and any code, and we will agree the next steps. The work covers multi-split systems, ceiling cassettes and heat pumps, and the jobs we see most are ice forming on the indoor unit or pipes and a unit that has lost refrigerant.
Across London, we work on the leading makes of air conditioning, from single wall units to multi-split systems. Where an old unit is not worth repairing, you will get an honest view and a price for replacing it.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

What a repair looks like in London
About 48% of homes in London and the neighbourhoods around it have been built since 2000, according to the Valuation Office Agency’s council tax figures, and the last census (2021) found about 93% of households live in flats. Outdoor units serving flats can be awkward to reach, so let us know where yours is. In London buildings, outdoor units can be on roofs or in light wells, so let us know where yours is. Roughly a third of a mile or less from central London, you reach the Trinity Church Square Conservation Area. Draw a one-mile circle round the middle of London and it takes in 32 conservation areas. Historic England lists about 156 buildings and structures within half a mile of the centre of London, including Church of St George the Martyr (grade II*). That only matters for replacements, where a new outdoor unit on a protected building can need consent.
For a school like Charles Dickens Primary School, urgent repairs can be booked right away and bigger work in the holidays. If your system near Elephant & Castle station stops in a hot spell, our 24/7 line is open.
London is in Greater London. Properties in London get the same service as everywhere we cover: diagnosis first, a fixed price and proper paperwork when we’ve finished. Our list for Greater London has 764 entries, and London is one.
The closest recent job we can point to from London was on Greenwich High Road, Greenwich (SE10), about 4 miles east: installing a Mitsubishi Electric wall-mounted unit in the retail area and a second unit in the stockroom and office.
That includes properties on Walcot Square, Surrey Square and Sutherland Square and nearby roads. Among the places we cover in Greater London, London is one of the largest. Places around London that are also on our list: Walworth (1 mile south), Bermondsey (1 mile east), Camberwell (2 miles south), South Bermondsey (2 miles south-east) and Surrey Canal (2 miles south-east). Larger places within reach include City of Westminster (3 miles west), Marylebone (3 miles north-west), Kensington (5 miles west) and Walthamstow (7 miles north-east).

Pricing air conditioning repair in London
You’ll get a fixed price before we start. It takes into account:
- Whether it’s a simple split or a larger system
- What electrical work the job needs
- The brand, model and parts involved
Several rooms, units or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed price.
What we need to know
To speed up the quote, send us:
- Where the outdoor unit is, or where you’d like it
- The paperwork from the last service, if you have it
- A photo of the consumer unit with the cover closed
Every quote shows the VAT clearly, and the rate that applies to your job is stated. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it on the quote. For a fixed-price quote, phone 07833 053749 or email us.

What else we do in London
London: your questions answered
Can you do air conditioning repair in London?
Yes. London is one of the places we cover. To start, phone us on 07833 053749 with a few pictures.
Can I get a fixed-price quote for air conditioning repair in London?
Use the quote form, or email, with a description of the job. We reply the same working day, and the quote is fixed before any work starts.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
Why is there ice on my air conditioning pipes?
When airflow drops or refrigerant is lost, the coil gets cold enough to ice. Check the filter first, and if it’s clean, the system needs a diagnosis.
Why isn’t my air con cooling?
Common causes are a blocked filter, the wrong mode or set temperature, an outdoor unit that cannot breathe, a failed sensor or board, or low refrigerant from a leak. Check the filter and the settings first, and if that does not fix it, ring 07833 053749 or send an email.
My air con is showing an error code. What should I do?
An error code points us in the right direction, but testing confirms the cause. Write down the code and turn the unit off if it has stopped, then phone us on 07833 053749 or drop us a line.
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
Honest limits
Not every problem is solved by air conditioning repair, and we’d rather say so up front. It does not solve:
- An old system with obsolete parts
- A room that overheats because of the building, such as a lack of shading or ventilation (the system may need help, not a repair)
- A system that was undersized for the room in the first place (that needs a bigger system, not a repair)
Not sure which it is? You can phone 07833 053749 or use the quote form and we’ll tell you honestly before booking.
Parts of the system we cover
- Multi-split systems
- VRF systems
- Heat pumps
- Wall-mounted split systems
- Ducted systems
- Ceiling cassettes
Why it’s worth doing now in London
For a newer system, a fault may be covered on the manufacturer’s terms. Tell us the make, model and install date and we’ll explain how the manufacturer’s terms are likely to apply first. Dealing with it now in London is typically simpler than an emergency later.
A single unit or a whole estate, the quote is built the same way: what needs doing, how we get to it and what it needs. You’ll have a fixed price before any work starts, with VAT shown clearly.
Why book with us
- MCS certification for heat pump work
- Electrical work covered by our NICEIC approval
- Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba and more
- One contact for properties across the South East and London
How it works
You do not need to do much on the day. Just let us in and point us to the units, or to where they’ll be fitted, and the rest is down to us. At the end, we tidy up and run through the work with you. Parking and access to the outside wall or roof are the main things to plan for a job in London.
- Diagnose: test the system until the cause is clear.
- Prescribe: tell you the cause and the fixed cost of the cure.
- 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.
- Sign off: prove it works and record the visit.
Preparing for the visit
- Mention any managing agent or landlord rules we need to follow
- Mention any roof access, ladders or high-level work
- Tell us about parking and loading
Ask for a quote

Advice
From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
