Air conditioning repair in Chalk Farm
A symptom is only a clue: warm air, drips and error codes can each have several causes. A unit blowing warm air might have a blocked filter, a failed sensor, a fault on the circuit board or a refrigerant leak, which is why diagnosis comes first. We’re often asked to deal with ice forming on the indoor unit or pipes and weak airflow from the indoor unit, across ducted systems, multi-split systems and wall-mounted split systems.
In Chalk Farm, as across London, air conditioning works hard in hot spells, which is when weak cooling, leaks and error codes tend to appear. A photo of the error code and the unit’s label helps us arrive with the right parts in mind.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. Where yours does, a regular service with us keeps that side in order, and every service is written up.

When it’s something else
We’d rather tell you now than sell you work that will not help, so these are the things it will not cover:
- A refrigerant fault on an R22 system (new R22 can’t be used for servicing, so replacement is typically the answer)
- A supply fault outside the property
- 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 email us and we will tell you honestly.
Where we work
- Multi-split systems
- Ceiling cassettes
- Wall-mounted split systems
- Ducted systems
- VRF systems
- Heat pumps
When to call us in Chalk Farm
Water dripping from an indoor unit is usually about the condensate. The drain may be blocked or kinked, the condensate pump may have failed, or the unit may not be level, while ice that forms on the coil and then melts can also cause drips.
Keep an eye out for these signs:
- A unit that won’t start
- A fault code on the display
- Rattling, buzzing or grinding noises
For a home or office near Kentish Town West station, tell us the make, model and error code when you call, so we can plan the repair.

How the visit works
We keep the work area tidy as we go, with sheets down and mess cleared as we go. If we need to drill through a wall, we agree the spot with you first. The visit takes an hour or two to diagnose most faults, with the repair time depending on what we find. Pictures of the space and the outside wall help us plan the work in Chalk Farm.
- Diagnose: test the system until the cause is clear.
- Next, a plain explanation and a fixed price.
- Where a repair doesn’t make sense, you will hear it from us, with the alternatives.
- The treatment: the repair itself, with any leak found and fixed before recharging.
- Sign off: prove it works and record the visit.
Before we arrive
- Make sure we can reach the consumer unit or fuse board
- Clear the space around the indoor unit, or where it will go
- Tell us about access, such as roof hatches, high walls or locked plant areas

What happens if it’s left?
Small faults rarely stay small. A drip can turn into a damaged ceiling, and a slow leak can leave the compressor straining, so getting it looked at early typically means a simpler repair. Approvals for flats in Chalk Farm can take longer than the install itself.
What you pay depends on the system and the number of rooms or units, how easy the units are to reach and what the work involves. You get a fixed price before we start, so there are no surprises.

Questions from Chalk Farm
Can I get a fixed-price quote for air conditioning repair in Chalk Farm?
Send us photos of the room or the system and a few details about the property. Where pictures aren’t enough, a survey comes first and the fixed-price quote follows.
Is there an emergency air con repair line for Chalk Farm?
Chalk Farm is within our area, and the emergency line is open 24/7. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
Can I do the refrigerant work myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Do you work on all makes?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.
Why is there ice on my air conditioning pipes?
When airflow drops or refrigerant is lost, the coil gets cold enough to ice. A dirty filter is worth checking first, and if it’s clean, the system needs a diagnosis.
Do you work on systems someone else installed?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Tell us the make and model and send any paperwork you have.
Why does my air conditioning run but not cool?
It could be a dirty filter, the wrong settings, a blocked outdoor unit, a sensor or board fault, or a refrigerant leak. Start by checking the filter and the mode, then phone us on 07833 053749 or email us if it’s still not cooling.
