About our air conditioning servicing in Millwall
Whether a leak check is required depends on how much refrigerant the system holds and which refrigerant it is. Under the GOV.UK rules, 5 to under 50 tCO2e means a leak check at least every 12 months, and 50 to under 500 tCO2e means every 6 months. We tell you which band your system falls into and carry out the checks it needs. The work covers ceiling cassettes, air-to-air heat pumps and wall-mounted split systems, and people most often call us about systems that need a 6 or 12-monthly leak check and warning lights on the indoor unit.
Systems in Millwall often run in both summer and winter, which is a good reason for a yearly service. Outdoor units on balconies and roofs pick up city dust and debris, and a clean coil cools better.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order, and every service is written up.

Servicing in Millwall: local notes
About 52% of homes in Millwall and the neighbourhoods around it have been built since 2000, according to Valuation Office Agency council tax records, and the 2021 Census found about 87% of households live in flats. Outdoor units serving flats can be awkward to reach, so let us know where yours is. In London, a yearly clean of the outdoor coil makes a real difference to how well a system cools. The centre of Millwall lies within the Chapel House Conservation Area. Draw a one-mile circle round the middle of Millwall and it takes in 7 conservation areas. Church of St Nicholas, listed at grade II*, is one of roughly 23 protected buildings and structures in the half-mile around Millwall’s centre. We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that.
Businesses close to Deptford station can book an early or late slot so the service does not get in the way of trade. For a school like Harbinger Primary School, maintenance visits can be booked out of term.

Millwall questions
Does my air con in Millwall need a yearly service?
Normally once a year for homes, more often for busy business systems. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.
Can you do air conditioning servicing in Millwall?
We do: Millwall falls inside our working area. Get in touch with the details and we reply the same working day.
Do you top up refrigerant during a service?
We check refrigerant performance on every service, but adding gas is separate work. If gas has been lost, the right step is a leak search and repair, then a regas, priced before any work starts.
Can I have a maintenance contract for my air conditioning?
Yes, with visits planned to suit how hard the system works. The price is fixed with your quote, and each visit is recorded.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
Why does F-Gas certification matter?
Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It means the refrigerant in your system is handled legally.
Who has to arrange F-Gas leak checks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Owner checks or an engineer?
On air conditioning, the filters in the indoor unit are usually the one part owners can clean, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo or a short video of the display is even better.

What else we do in Millwall
Keeping the system healthy
Aftercare is straightforward, and it makes the next visit easier:
- Know your manufacturer’s servicing conditions
- Rinse the indoor unit filters every few weeks when the system is in heavy use
- Report drips, smells or noises early
After the service, you get a record of what was done, listing the work, the checks and any recommendations. File it with the system’s manual and warranty documents so the service history is in one place.
Book a service at least once a year with extra visits where the system runs constantly or needs more frequent leak checks.
Leave it or put it right?
Servicing is planned, priced and booked at a time that suits you. A fault picks its own moment, so a planned visit is the easier option. Hot weather is when everyone in London wants air conditioning, so it’s easier to plan the work in Millwall early.
What you pay depends on the type of system and how many units are involved, the access and the parts and time the job needs. You get a fixed price before we start, so there are no surprises.

The process
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. On site, it takes an hour or so for a single wall-mounted unit, longer for a multi-split system. In a London area like Millwall, parking and access are worth sorting out before the day.
- 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.
- Dust and grime come off the filters and coils, and the drain is flushed so water runs away properly.
- Next come the terminals, the controller and the refrigerant side, with a leak check if the system’s size makes one a legal duty.
- We leave you a record of the service and explain anything we found.
Preparing for the visit
- Tell us about any building rules, permits or sign-in
- Make sure someone can let us in at the agreed time
- Move furniture away from the wall where we’ll be working

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
