Air Conditioning Repair in Chelsea
Need air conditioning repair in Chelsea? We diagnose first, fix the price and book the work around you, then sign it off with written records.
- Water dripping from the indoor unit
- A unit blowing warm air
- A system that won’t switch on
After we have gone
How well a system lasts depends on use and care. Here’s what we suggest:
- Leave a tripping breaker off and call us
- Book an annual service after the repair
- Turn the system off if it’s dripping water
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.
Sensible use helps. Moderate settings and a closed room mean less strain and the system does not have to work as hard.
Air conditioning repair for homes and businesses in Chelsea
Any repair we carry out in Chelsea starts the same way: fault codes, electrics, airflow, drain and refrigerant are all checked. Then we explain what’s wrong and give you a fixed price to put it right. If you’re dealing with air conditioning running but not cooling and a fault code on the display, we can help.
In Chelsea, as across London, air conditioning works hard in hot spells, and that is when faults show: weak cooling, water leaks, error codes or a unit that will not start. A photo of the error code and the unit’s label helps us arrive with the right parts in mind.
The records are your system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler, so keep it safe.

The process
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First comes a careful look at the system or the space, then the work itself, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, and that takes as long as the fault needs, from a quick fix to a return visit for parts. The more we can see beforehand, the smoother the visit to Chelsea will be.
- First the diagnosis: fault codes read, electrics and airflow checked, drain and refrigerant tested.
- Next, a plain explanation and a fixed price.
- 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.
Preparing for the visit
- Keep pets out of the rooms we are working in
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Mention any managing agent or landlord rules we need to follow

Questions from Chelsea
Is Chelsea in your area for air conditioning repair?
Yes. Chelsea is one of the places we cover. Get in touch with the details and we reply the same working day.
Can I get a fixed-price quote for air conditioning repair in Chelsea?
Send us pictures of the room or the system and a few details about the property. Simple jobs can be priced from pictures; otherwise we arrange a site survey and then give you a fixed-price quote.
Do I need to service the system to keep the warranty?
It can, for some brands. Read the manufacturer’s terms, or send us the make and model and we’ll explain them and stick to the interval they set.
How quickly will you reply?
On the same working day you contact us. Then we agree a date that works for you, with a fixed price before work starts.
Do you survey before quoting?
Yes. Every job is looked at first, on a survey, or from your photos and details where the job is simple. A fixed-price quote follows.
Can you come out for an emergency air conditioning repair?
Yes, 24/7. Emergencies include water coming through a ceiling or a critical room overheating and we will tell you what to do first. The number is 07833 053749.
What can I do with an old R22 system?
In most cases, we recommend replacement. New R22 cannot be used to service systems, and parts for older units are getting harder to find, so a new system on a modern refrigerant is typically the better investment.
When it’s something else
We’ll always give you a straight diagnosis, so here’s what air conditioning repair will not do:
- A supply fault outside the property
- Heat gains the system was never designed for
- A leak on an old R22 system
If in doubt, phone us on 07833 053749 or use the quote form and we’ll say what we think before booking.
Parts of the system we cover

When air con fails in Chelsea
The Valuation Office Agency’s council tax figures put about 68% of homes in Chelsea and the neighbourhoods around it before 1919, and the last census (2021) found about 76% of households live in flats. In flats, outdoor units are often on balconies, roofs or high walls, so tell us how we reach yours. London repairs often depend on reaching the outdoor unit, so access details help us plan. The middle of Chelsea is part of the Chelsea Conservation Area. In the mile around Chelsea’s centre, 20 conservation areas have been designated. Listed buildings are part of the picture here: about 339 within half a mile of the centre, such as Church of St Luke (grade I). That only matters for replacements, where a new outdoor unit on a protected building can need consent.
Schools such as Oratory Roman Catholic Primary School can report a fault on the 24/7 line and have non-urgent work done out of term. Before you call, note what the unit is doing and any code on the controller.

What else we do in Chelsea
System by system
Multi-split systems
Refrigerant leaks on a multi-split can be anywhere on several pipe runs. We test each run to find it, then repair, pressure test and recharge.
VRF systems
On larger VRF systems, the refrigerant charge can be big enough to need regular leak checks under the F-gas rules. Leak repairs are written into the F-Gas records for the operator’s records.
From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
