Air conditioning repair in Knightsbridge, Greater London
Air conditioning repair across Knightsbridge and nearby, from a site survey or diagnosis to sign-off and a fixed price agreed before work begins.
- Water leaking from the unit or through the ceiling
- Frost on the pipework
- A flashing light and a system that will not run
How it works
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we have done and answer any questions, and anything that needs a follow-up is pointed out there and then. The visit takes anything from an hour or so to a full day, depending on the fault and the parts. Parking bays, permits and roof or balcony access are the first things we ask about in Knightsbridge.
- First the diagnosis: fault codes read, electrics and airflow checked, drain and refrigerant tested.
- Then the prescription: what’s wrong and what it will cost to put right.
- If the repair isn’t 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.
Getting ready for the visit
- Let us know if the building has a permit or sign-in process
- Tell us about parking and loading
- Dig out any previous service or F-Gas records

Air conditioning repair in Knightsbridge
We repair air conditioning on all the main brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Systems fitted by other installers are fine too and the make and model help us prepare. We’re often asked to deal with water leaking from the unit or through the ceiling and a system that won’t switch on, across ducted systems, heat pumps and VRF systems.
In a managed building in Knightsbridge, the repair may need booking through the agent or building manager, so let us know who needs to know we are coming. Outdoor units on roofs may need a key, a permit or an escort, which is worth sorting before the visit.
We are an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Do you need air conditioning repair in Knightsbridge?
When the fan runs but the air isn’t cold, there are some common causes: a blocked filter, the wrong mode or set temperature, an outdoor unit that can’t breathe, a failed sensor or board, or low refrigerant from a leak. Diagnosis narrows it down.
Reasons to give us a call include:
- Poor airflow even with clean filters
- Water dripping from the indoor unit
- New noises from the system
For a school like Hellenic College of London, urgent repairs can be booked right away and bigger work in the holidays.

Questions from Knightsbridge
Who do I call if my air conditioning fails in Knightsbridge out of hours?
Yes. Our 24/7 emergency line covers Knightsbridge. Say what the system is doing and whether it shows a code, and we will advise on the next step.
Can you do air conditioning repair in Knightsbridge?
We do: Knightsbridge falls inside our working area. Tell us a little about the job and we will take it from there.
Do I need to service the system to keep the warranty?
It depends on the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so it’s worth checking. Keep every service record either way.
Can you repair an R22 air conditioning system?
Most of the time, we recommend replacement. New R22 can’t be used to service systems, and parts for older units are getting harder to find, so we will quote for a modern replacement and explain why.
How much is an air conditioning call-out?
It starts with a diagnosis call-out from £75 + VAT, and then you get a fixed price for the repair. Nothing goes ahead without your agreement.
Why is my air conditioning blowing warm air?
It can be anything from a dirty filter to a refrigerant leak. Diagnosis confirms the cause, then give you a fixed price to fix it.
Can you look at a system you didn’t fit?
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.
