Air conditioning repair for homes and businesses in Sydenham Hill
Not sure whether it’s worth calling an engineer? Check the filter, the mode, the set temperature and the remote’s batteries first, and if that doesn’t fix it, call us on 07833 053749 or fill in the contact form. You’ll hear back from us the same working day. If you’re dealing with new noises from the system and poor airflow even with clean filters, we can sort it out.
Many buildings in Sydenham Hill have a managing agent or security desk, so let us know who needs to know we’re coming. Roof access can need keys or permits, and we plan for that before we arrive.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual, because it helps with any later warranty question.

How it works
We book the visit for a day and time that suit you, and we let you know if plans need to move. On arrival, the engineer compares the job with the survey, your photos or the details you gave us. Anything unexpected is raised with you before we go further. From there, the work takes as long as the fault needs, from a quick fix to a return visit for parts. Pictures of the space and the outside wall help us plan the work in Sydenham Hill.
- Diagnose: test the system until the cause is clear.
- Then the prescription: what’s wrong and what it will cost to put right.
- If the repair is not worth doing, we say so and explain the options.
- Treat: carry out the repair, sealing any leak before refrigerant goes back in.
- Finally, a check that it’s working and a record of what we did.
How to prepare
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Keep pets and children away from the work area
- Make sure we can reach the consumer unit or fuse board
Getting a quote

Sydenham Hill questions
Is there an emergency air con repair line for Sydenham Hill?
The emergency line is open around the clock, and Sydenham Hill is one of the places it covers. Have the make, model and error code ready, and we’ll talk you through what happens next.
Can you do air conditioning repair in Sydenham Hill?
Yes. Sydenham Hill is one of the places we cover. Get in touch with the details and we reply the same working day.
What can I do with an old R22 system?
Servicing with new R22 is not allowed, because it depletes the ozone layer. Some non-refrigerant faults can be repaired if parts are available, but a refrigerant leak usually means replacement. We will set out the options and quote for a replacement where it makes sense.
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. Check the filter and the settings first, and if that does not fix it, give us a ring on 07833 053749 or send an email.
Do I get paperwork after the visit?
Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.
What does an air con repair cost?
Diagnosis call-outs start from £75 + VAT. When we have found the fault, the repair is priced before we do it. The final cost depends on the fault, the parts and the access.
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 the area is kept tidy throughout. At the end, we clear up and show you what we’ve done.
What affects the cost of air conditioning repair
The survey or diagnosis tells us what the work involves. We look at:
- The electrical supply and whether a new circuit is needed
- What we find on the survey or diagnosis
- The equipment or parts the job needs
The price reflects the work, not guesswork. That is why we look at the job first, from photos or on a survey, and why the quote is fixed before any work starts.
What to send for a quote
Photos and a few facts are often enough to price a simple job. Send what you can of the following:
- The make and model of the system, from the label
- The fuse board and where it is in the property
- The paperwork from the last service, if you have it
To help us quote: the address and the type of property, a few photos, the brand and model of anything already fitted and anything you’ve noticed, such as an error code or a noise. Once you have those, give us a ring on 07833 053749 or email us.
When it’s something else
Some problems need a different service or another trade:
- A leak on an old R22 system
- Heat gains the system was never designed for
- A power cut or a fault on the incoming supply to the building (that is for the network operator)
If you’re not sure, just phone 07833 053749 or fill in the contact form and we will give you a straight answer before you book.

Air conditioning repair in Sydenham Hill: the local picture
Valuation Office Agency council tax records date about 48% of homes in the Sydenham Hill area to the post-war years, 1945 to 1972, and the last census (2021) found about 66% of households live in flats. If you live in a flat, mention any roof hatch, balcony or managing agent we’ll need to get to the outdoor unit. London repairs often depend on reaching the outdoor unit, so access details help us plan. Sydenham Hill’s centre falls inside the Dulwich Wood Conservation Area. In the mile around Sydenham Hill’s centre, 9 conservation areas have been designated. Historic England lists about 26 buildings and structures within half a mile of the centre of Sydenham Hill, including Church of St Bartholomew (grade II*). We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that.
Shops and offices around Sydenham Hill station often can’t wait for cooling to come back, which is what the 24/7 line is for. When cooling fails at a school like Kelvin Grove Primary School, we can time non-urgent repair work around lessons.

Before you call an engineer
Don’t 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.
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and ring 07833 053749 or email us.
