Air conditioning repair for homes and businesses in Sidcup
Age alone doesn’t decide whether a repair is worth it. A fan fault on an older unit can be worth fixing, while a compressor failure may tip the balance. You get an honest view based on the fault, the parts, the refrigerant and the room. The work covers ceiling cassettes, heat pumps and VRF systems, and the jobs we see most are a system that needs topping up again and rattling, buzzing or grinding noises.
In Sidcup, 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.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

Looking after your system
After the visit, a few habits help:
- Have the system serviced once a year
- Clear debris away from the outdoor fan
- Note any error code, or take a photo of the display
The repair is written up: the cause, the parts fitted and any refrigerant added or recovered. Any refrigerant work is recorded in the F-Gas records, so keep the note with the system’s paperwork.
Filter cleaning is the simplest prevention there is. Blocked filters cut airflow, which can lead to poor cooling, ice on the coil and drips, so keep them clean as the manual describes.

What else we do in Sidcup
How the visit works
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First we check the system or the space against the plan, then the work itself, and finally we test, record and explain. The middle part takes longest, which takes as long as the fault needs, from a quick fix to a return visit for parts. A few photos of the room, the outside wall and the fuse board help us plan a job in Sidcup.
- Diagnose: test the system until the cause is clear.
- Next, a plain explanation and a fixed price.
- Where a repair does not make sense, you’ll hear it from us, with the alternatives.
- 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
- Mention any managing agent or landlord rules we need to follow
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Tell us about parking and loading

Sidcup questions
Is Sidcup in your area for air conditioning repair?
Yes, Sidcup is within the area we cover. To start, call us on 07833 053749 with a few photos.
Is there an emergency air con repair line for Sidcup?
Sidcup 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.
Why isn’t my air con cooling?
It can be anything from a dirty filter to a refrigerant leak. We read any fault code and test the system to find which and you get a fixed price before the repair.
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 a new system on a modern refrigerant is normally the better investment.
Can you still repair R410A air conditioning?
Yes. Any leak is repaired before recharging, and the work is recorded, and we tell you honestly whether a repair is worth it on an older system.
Who has to arrange F-Gas leak checks?
Responsibility is shared between the operator, normally whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Why is my air conditioning showing a fault code?
Each manufacturer uses its own codes, and one code can have more than one cause. Send us a photo of the display with the make and model, and we’ll diagnose the fault on site.
When air con fails in Sidcup
The Halfway Street Conservation Area is within about a third of a mile of the centre of Sidcup. In the mile around Sidcup’s centre, 8 conservation areas have been designated. Number 33 (farm Cottage) and Number 35, listed at grade II, is one of roughly 7 protected buildings and structures in the half-mile around Sidcup’s centre. We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that. About 46% of households live in flats, according to the 2021 Census. Outdoor units serving flats can be awkward to reach, so let us know where yours is. In London, access to outdoor units on roofs and balconies can need planning, so tell us how to reach yours.

System by system
Fans and compressors
At the centre of the system is the compressor. Compressor faults can sometimes be caused by something else, such as an electrical fault or a refrigerant problem, so we test before condemning it. A failed compressor often raises the repair-or-replace question, and we give you both prices.
Ducted and cassette systems
With ducted and cassette units, most of the system is hidden in the ceiling, so access matters. Many have condensate pumps, and pump failures are a common cause of ceiling leaks.
What we’re called out for in Sidcup
Rattles, buzzes and grinding sounds tend to be mechanical. Worn fan bearings, loose panels, debris in the outdoor fan or pipework vibrating against the building are common, and some noises point to the compressor.
It’s time to call us if you are dealing with:
- A system that will not switch on
- A noisy indoor or outdoor unit
- A unit that has lost refrigerant
Schools such as Birkbeck Primary School can report a fault on the 24/7 line and have non-urgent work done out of term.
