Air Conditioning Servicing in Marylebone
We cover Marylebone for annual servicing and F-Gas leak checks for domestic and commercial air conditioning. Diagnosis first, a fixed price and proper paperwork when we finish.

Air conditioning servicing in Marylebone
Air conditioning pulls room air through a filter and across a cold coil many times an hour. Dust, fluff and anything else in the air ends up on those parts. Servicing removes it, so the system can move air properly and the drain can do its job. Typical jobs include ice forming on the pipework or outdoor unit and humming, rattling or squealing from the system, on multi-split systems, ceiling cassettes and wall-mounted split systems.
For a flat or office in Marylebone, tell us where the outdoor unit is and how we reach it, so let us know how to get to it. If the building has a managing agent, we can book in with them.
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.

How the visit works
Where something has to be switched off during the work, we agree it with you first so it doesn’t catch you out. In a business, work can often be done one area at a time. On site, it takes anything from an hour for a simple split system to most of a day for a larger installation. Send us a few phone pictures and we can often price a straightforward job in Marylebone before visiting.
- We start with the basics, such as the brand, the number of indoor units and any symptoms.
- We run the system first and see how it’s performing.
- Filters are cleaned, coils treated and the drain tray and pipe cleared.
- The wiring, controls and refrigerant performance are checked, plus a leak check on systems large enough to need one.
- Before leaving, the engineer writes up the visit and talks you through anything worth knowing.
How to prepare
- Clear the space around the indoor unit, or where it will go
- Let us know if the building has a permit or sign-in process
- Let us know where the consumer unit is
Getting a quote
Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.
Advice
What air conditioning won’t do
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- Rooms that gain heat faster than any unit could cope with
- A system short of gas because of a leak
- Poor original installation, such as drains without a proper fall
If in doubt, ring 07833 053749 or drop us a line and we’ll say what we think before you book.
What the work covers
- VRF systems
- Air-to-air heat pumps

For landlords and property managers
From a single flat to a whole estate, you get the same standard: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.
Records are where property maintenance often slips. Each visit is written up, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.
Servicing in Marylebone: local notes
Marylebone’s centre falls inside the Harley Street Conservation Area. Draw a one-mile circle round the middle of Marylebone and it takes in 19 conservation areas. Chandos House, listed at grade I, is one of roughly 695 protected buildings and structures in the half-mile around Marylebone’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 50% of homes in Marylebone and the neighbourhoods around it were built before 1919, according to Valuation Office Agency council tax records, and about 92% of households live in flats, according to the 2021 Census. If you live in a flat, mention any roof hatch, balcony or managing agent we’ll need to get to the outdoor unit. In London, a yearly clean of the outdoor coil makes a real difference to how well a system cools.
Offices and shops near Bond Street station can have their systems serviced without closing.

Common problems we fix in Marylebone
Small refrigerant leaks do not announce themselves. Performance drops slowly, until it can’t keep up on the hottest or coldest days.
The things we are asked about most are:
- Water dripping from the indoor unit
- An unpleasant odour when the system runs
- Frost or ice on the refrigerant pipes
Site managers at schools like St Vincent's Catholic Primary School can have the site’s units serviced during a holiday.

Common questions in Marylebone
Does my air con in Marylebone need a yearly service?
A yearly visit is right for most households. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.
Is Marylebone in your area for air conditioning servicing?
Yes, Marylebone is within the area we cover. To start, phone 07833 053749 with a few photos.
Why use an F-Gas certified company?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. In Great Britain, that certification is a legal requirement, not an optional extra, and we hold it.
Do you provide F-Gas records?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.
Which brands do you work with?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and tell you why.
Is a regas part of an air conditioning service?
Refrigerant is only added after the leak that caused the loss has been dealt with. Adding gas without a repair just lets it leak away again and that is money wasted.
When is an F-gas leak check required?
The GOV.UK rules set leak checks at least every 12 months for 5 to under 50 tCO2e and every 6 months for 50 to under 500 tCO2e. With leak detection fitted, the interval can be doubled, and we can tell you where your system sits.
