Air conditioning repair for homes and businesses in Telegraph Hill
Across Telegraph Hill, every repair begins with a diagnosis: the engineer reads the fault codes and checks the electrics, the airflow, the condensate drain and the refrigerant pressures and temperatures. Then we explain what’s wrong and give you a fixed price to put it right. The work covers ceiling cassettes, wall-mounted split systems and multi-split systems, and the jobs we see most are a noisy indoor or outdoor unit and water leaking from the unit or through the ceiling.
London systems in Telegraph Hill often run long hours in summer, 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.
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.

Your questions about air conditioning repair in Telegraph Hill
Who do I call if my air conditioning fails in Telegraph Hill out of hours?
Yes. Our 24/7 emergency line covers Telegraph Hill. 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 Telegraph Hill?
Yes. We work across London and the South East from our base in East Grinstead, and Telegraph Hill is part of that. Get in touch with the details and we reply the same working day.
Why does my air conditioning run but not cool?
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.
Why is my air conditioning icing up?
It typically points to poor airflow or a refrigerant leak. Blocked filters, a failing fan or a leak are the common causes. Turn it off, let the ice melt and call 07833 053749 or write to us at info@aircondoctor.co.uk.
What warranty do I get?
Warranty comes from the manufacturer and depends on the brand and product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and we explain the terms for whichever brand you choose.
How do you keep the place clean during the work?
Floors and furniture near the work are covered with dust sheets before we start, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
Before you call an engineer
Good habits make our visits easier, not unnecessary. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo or a short video of the display is even better.
How the visit works
The work area is kept tidy throughout, with dust sheets down and offcuts and packaging cleared up. 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. Parking bays, permits and roof or balcony access are the first things we ask about in Telegraph Hill.
- Diagnosis comes first: codes, electrics, airflow, drain and refrigerant.
- Next, a plain explanation and a fixed price.
- Where a repair does not make sense, you’ll hear it from us, with the alternatives.
- Treat: carry out the repair, sealing any leak before refrigerant goes back in.
- Sign off: prove it works and record the visit.
Getting ready for the visit
- Arrange for someone to be there to let us in
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Clear the space around the indoor unit, or where it will go

Why it’s worth doing now in Telegraph Hill
Leaving a fault seldom makes it go away. A blocked drain becomes water damage, and a slow leak drains the refrigerant until the compressor is working far harder than it should, so getting it looked at early typically means a simpler repair. If a lease or managing agent is involved in Telegraph Hill, start the conversation early.
The cost depends on the system and the number of rooms or units, how easy the units are to reach and the parts and time the job needs. We give you a fixed price before we start, so you know where you stand.

Keeping the system healthy
Aftercare is straightforward, and it helps at the next service:
- Send us a photo of any code on the display
- Check the settings and the remote’s batteries first
- Have the system serviced once a year
The repair is written up: what was wrong, what was replaced and any refrigerant work. Refrigerant work goes into the F-Gas records and it belongs with the system’s paperwork.
Clean the filters regularly. Clogged filters starve the unit of air, and that can cause ice, drips and poor performance and the manual shows how to clean them.
