What a repair looks like in Coldharbour
The centre of Coldharbour lies within the Coldharbour Conservation Area. There are 10 conservation areas within a mile of the centre of Coldharbour. On the National Heritage List, around 20 entries fall within 0.5 miles of the middle of Coldharbour; Church of St Matthias (grade II*) is one. Day-to-day work on an existing system isn’t affected; a replacement outdoor unit on a protected building might be. About 82% of homes in Coldharbour and the neighbourhoods around it have been built since 2000, according to VOA council tax data, and the last census (2021) found about 95% of households live in flats. Balcony, roof or high wall? Knowing where a flat’s outdoor unit is helps us bring the right access kit. London repairs often depend on reaching the outdoor unit, so access details help us plan.
If a system fails at a school such as Woolmore Primary School, our 24/7 line takes the call, and planned repairs can wait for the holidays.

Air conditioning repair for homes and businesses in Coldharbour
Any repair we carry out in Coldharbour starts the same way: fault codes, electrics, airflow, drain and refrigerant are all checked. After that, you get a plain explanation and a fixed price for the repair. The work covers multi-split systems, ceiling cassettes and ducted systems, and the jobs we see most are water dripping from the indoor unit and poor airflow even with clean filters.
In Coldharbour, as across London, air conditioning works hard in hot spells, which is when weak cooling, leaks and error codes tend to appear. The error code on the display, the make and the model are the most useful things to send us.
Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

More services for Coldharbour
Owner checks or an engineer?
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and give us a ring on 07833 053749 or drop us a line.
Do not move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. If you need something moved, we can quote for it.
Common questions in Coldharbour
How do I get a quote for air conditioning repair in Coldharbour?
Start with a short message: the address, what you need and a picture or two. Simple jobs can be priced from pictures; otherwise we arrange a site survey and then give you a fixed-price quote.
Can you do air conditioning repair in Coldharbour?
Yes. Coldharbour is one of the places we cover. Get in touch with the details and we reply the same working day.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Can you repair an R22 air conditioning system?
R22 is an ozone-depleting refrigerant, and new R22 can’t be used for servicing. A fault that doesn’t involve the refrigerant may still be repairable, depending on parts, but a leak usually makes replacement the sensible route. We explain the options and quote for a new system if that is the answer.
Why does my air conditioning run but not cool?
Common causes are 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. Start by checking the filter and the mode, then call 07833 053749 if it’s still not cooling.
Whose job is it to check the system for leaks?
Responsibility is shared between the operator, typically whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Why is my air conditioning showing a fault code?
An error code points us in the right direction, but testing confirms the cause. Note the code and switch the system off if it isn’t working, and call us on 07833 053749 or email us.
What happens on the day
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. For businesses, we can typically work room by room or zone by zone. The work takes a single visit for many faults, while some repairs need a second visit once parts arrive. A few pictures of the room, the outside wall and the fuse board help us plan a job in Coldharbour.
- Describe the problem and the brand, and mention any code on the display.
- A diagnosis visit finds the cause with proper tests.
- You get the cause explained and a fixed price for the repair.
- Once agreed, the repair goes ahead.
- It’s tested running, and the write-up is left with you.
Preparing for the visit
- Make sure we can reach the consumer unit or fuse board
- Keep pets and children away from the work area
- Have the make and model of any existing unit to hand

When to call us in Coldharbour
Some faults stop the unit completely: fan motors, boards, interconnecting cables and tripped breakers. If a breaker trips again after you reset it, leave it off and call us.
Any of these is worth a proper look:
- Water leaking from the unit or through the ceiling
- A unit that barely blows any air
- A unit that won’t start
For a home or office near Canary Wharf station, tell us the make, model and error code when you call, so we can plan the repair.

Aftercare tips
Every system needs looking after, and most of it is easy. Our tips:
- Write down the fault code if there is one
- Turn the system off if it’s dripping water
- Clear debris away from the outdoor fan
Once the fault is fixed, we test the system in operation. We confirm it’s working properly and look for anything else that needs attention and point out anything else we spotted.
Keep the outdoor unit clear. Anything blocking the outdoor unit makes the whole system strain and debris drawn into the fan can cause noise and damage.
What a customer said
“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.”
