Air conditioning servicing for homes and businesses in Custom House
Servicing covers both halves of the system: the indoor units in the rooms and the outdoor unit outside. We clean the filters and coils, clear the condensate drain, check the electrics and controls, and look at how the refrigerant circuit is performing. We service systems in Custom House and across Greater London, for most leading brands. The work covers ceiling cassettes, multi-split systems and ducted systems, and common reasons people get in touch are error codes or flashing lights on the indoor unit and an unpleasant odour when the system runs.
For a flat or office in Custom House, tell us where the outdoor unit is and how we reach it, so let us know how to get to it. Managed buildings may need the visit booked through the agent.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

Common questions in Custom House
Do you cover Custom House for air conditioning servicing?
Yes. Custom House is one of the places we cover. To start, call 07833 053749 or email us with a few pictures.
How often do you service systems in Custom House?
Once a year suits most home systems. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.
Are you F-Gas certified?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Do you provide F-Gas records?
Yes. It’s the record a manufacturer or the next engineer will ask to see: the date, the work, and any refrigerant added or recovered.
Is an F-gas leak check a legal requirement for my system?
Only if the system is at or above the threshold of 5 tCO2e. Many small split systems fall below it: 3 kg of R32, for instance, is about 2.0 tCO2e. We read the charge from the label and work it out for you.
Do you offer air conditioning maintenance contracts?
Yes, for homes and businesses. We fix the schedule, the scope and the cost with your quote and the servicing happens on time.
Do I need a service to keep the manufacturer’s warranty?
The answer is in your manufacturer’s warranty conditions. If servicing is required, a regular service record is the evidence, and we can explain what your brand asks for.
Looking after your system
A little care keeps the system in better shape. Our advice:
- Hold on to every service report
- Read the warranty conditions for your brand
- Make sure the condensate outlet can drain
After the service, you get a record of what was done, with the checks carried out and anything we’d recommend. File it with the system’s manual and warranty documents so you have the whole history together.
Check that the condensate pipe outside can still drain. A pipe that’s been knocked or covered can back up into the indoor unit.
Owner checks or an engineer?
Don’t move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. Ask us to quote for a move instead.
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
What happens on the day
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. The middle part takes longest, which takes an hour or so for a single wall-mounted unit, longer for a multi-split system. Some blocks in Custom House need contractor details in advance, so tell us what your building needs.
- We start with the basics, such as the brand, the number of indoor units and any symptoms.
- The engineer switches the system on and checks how it behaves before taking anything apart.
- Filters, coils and the condensate drain are cleaned and cleared.
- Electrical connections, controls and refrigerant performance are checked, with an F-gas leak check where the system requires one.
- We leave you a record of the service and explain anything we found.
Preparing for the visit
- Arrange for someone to be there to let us in
- Plan for pets to be kept clear during the visit
- Tell us about any building rules, permits or sign-in

Air conditioning servicing in Custom House: the local picture
On the National Heritage List, around 5 entries fall within 0.5 miles of the middle of Custom House; Warehouse K (grade II) is one. We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that. About 64% of homes across Custom House and its surrounding area have been built since 2000, according to Valuation Office Agency council tax records, and about 76% of households live in flats, according to the last census (2021). Outdoor units serving flats can be awkward to reach, so let us know where yours is. London outdoor units collect city dust and grime, so the outdoor coil gets particular attention on a service.
If you run premises near Custom House station, ask about servicing several units in one visit. Site managers at schools like St Joachim's Catholic Primary School can have the site’s units serviced during a holiday.

What else we do in Custom House
Different systems, different jobs
Wall-mounted, ducted and cassette units
With a ducted system, the unit is hidden above the ceiling. Servicing means reaching the unit through an access hatch, so let us know where the hatch is.
Refrigerant performance and leak checks
The law requires leak checks once a system reaches 5 tCO2e: at least every 12 months from 5 to under 50 tCO2e, and every 6 months from 50 to under 500 tCO2e. Hermetically sealed equipment holding less than 10 tCO2e doesn’t need them.
A customer’s words
“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.”
