About our air conditioning repair in Chinatown
Think of it as a doctor’s appointment for your air conditioning: find the cause, put it right and check it’s healthy before we leave. Guessing is expensive, and topping up refrigerant on a system with a blocked filter fixes nothing. We are often asked to deal with ice on the pipework or the coil and rattling, buzzing or grinding noises, across ceiling cassettes, ducted systems and heat pumps.
In a London area like Chinatown, a lot of the systems we repair serve flats and small offices, with outdoor units on balconies, rear walls or flat roofs. Telling us where the outdoor unit is and how we reach it saves time on the visit.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, ready for the next service or a warranty query.

What a repair looks like in Chinatown
Chinatown’s centre falls inside the Leicester Square Conservation Area. 32 conservation areas lie within a mile of central Chinatown. Listed buildings are part of the picture here: about 994 within half a mile of the centre, such as House of St Barnabas (grade I). For most visits that makes no difference. It only comes up when an outdoor unit has to be replaced on a protected building. About 50% of homes across Chinatown and its surrounding area were built before 1919, according to Valuation Office Agency council tax records, and the 2021 Census found about 97% of households live in flats. If you live in a flat, mention any roof hatch, balcony or managing agent we will need to get to the outdoor unit. In London, access to outdoor units on roofs and balconies can need planning, so tell us how to reach yours.
When cooling fails at a school like Soho Parish CofE Primary School, we can time non-urgent repair work around lessons. Shops and offices around Tottenham Court Road station often cannot wait for cooling to come back, which is what the 24/7 line is for.
Chinatown is about 1 mile east of City of Westminster, in Greater London. Wherever you are in the W1F postcode area, our engineers can take on air conditioning repair. Across Greater London, we cover 764 places, and Chinatown is one of them.
Our nearest recent job to Chinatown was on East Hill, Wandsworth (SW18), about 5 miles south-west: installing a Daikin wall-mounted unit in the open-plan living area.
Duck Lane, Drury Lane and Bruton Lane and the roads off them are all inside our area. The A4 and A301 serve Chinatown, which keeps journeys to surveys and visits simple. Neighbouring places we cover include Soho (1 mile north), St James's (1 mile south), West End (1 mile north-east), Seven Dials (1 mile north-east) and St Giles (1 mile north-east). Larger places within reach include Kensington (3 miles west), Shoreditch (3 miles north-east), Walthamstow (7 miles north-east) and Hoxton (3 miles north-east).
Around Chinatown
In Chinatown, that means homes and buildings near LITE Regal International School, London Library and Waxy O'Connor's pub, among other places. Also close by are St Anne's Churchyard (under half a mile north-west) and Harris Westminster Sixth Form (0.8 miles south). There’s a railway station in Chinatown itself: Tottenham Court Road station. Other landmarks nearby include Leverian collection (less than half a mile south-east) and Montfichet's Tower (1.3 miles east). Green spaces nearby include Barnsbury Wood and St. James's Park Lake.
For landlords and property managers
We regularly work with managing agents. Tell us the property, the work and the access arrangements and we will come back with a fixed-price quote.
Whether it’s one property or many, you get the same standard: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
Aftercare tips
A little care keeps the system in better shape. We recommend:
- Switch the unit off if water is leaking from it
- Rule out the simple causes first: filter, mode and temperature
- Send us a photo of any code on the display
After the repair, the system is run and checked in every mode it has. We confirm it’s working properly and look for anything else that needs attention and point out anything else we spotted.
Give the outdoor unit space. Anything blocking the outdoor unit makes the whole system strain, and debris can get into the fan.

Chinatown: your questions answered
Do you cover Chinatown for air conditioning repair?
Yes. We work across London and the South East from our base in East Grinstead, and Chinatown is part of that. To start, call us on 07833 053749 with a few pictures.
Is there an emergency air con repair line for Chinatown?
Yes. Our 24/7 emergency line covers Chinatown. Say what the system is doing and whether it shows a code, and we’ll advise on the next step.
How long will you be on site?
We’ll confirm the time with your quote. As a guide, the work takes a single visit for many faults, while some repairs need a second visit once parts arrive.
Who is responsible for leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. 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.
Can you repair an R22 air conditioning system?
Servicing with new R22 is not allowed, because it depletes the ozone layer. A fault that doesn’t involve the refrigerant may still be repairable, depending on parts, but a leak typically makes replacement the sensible route. We explain the options and quote for a new system if that’s the answer.
Will skipping a service affect the warranty?
It can, for some brands. Read the manufacturer’s terms, or send us the make and model and we will explain them, and book the service at the interval they recommend.
Do you work on systems someone else installed?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Tell us the make and model and send any paperwork you have.
What happens if it’s left?
Running with a fault wastes electricity. Poor airflow or low refrigerant means more running time for less effect, and the extra strain can shorten the life of the compressor. Consents in London blocks can take time, which is another reason to plan the job in Chinatown early.
Height, access and the distance between the indoor and outdoor units all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.

How the visit works
Each visit follows the same order: check the plan with you, put the dust sheets down, do the work, test what we have done and explain it all to you. The visit itself takes as long as the fault needs, from a quick fix to a return visit for parts. Before a visit in Chinatown, we ask where the van can stop and how we reach the outdoor unit.
- You tell us the symptoms, the make and any error code.
- On the diagnosis visit, we test the electrics, airflow, drain and refrigerant.
- The fault is explained simply and the repair priced up front.
- Once agreed, the repair goes ahead.
- We test the system in operation and leave you a note of the fault and the fix.
How to prepare
- Plan for pets to be kept clear during the visit
- Dig out any previous service or F-Gas records
- Make sure we can reach the outdoor unit, or where it will go
