How we price air conditioning servicing
Your quote is based on your property. We take into account:
- How many units are involved
- One-off work versus a regular service cycle
- The condition of any existing system
What you pay reflects the actual work. That’s why we look at the job first, from photos or on a survey, and why the quote is fixed before any work starts.

When you call or email, these details help:
- Your installation or service records
- The fuse board and where it is in the property

How we handle air conditioning servicing in Northfields
A manufacturer’s warranty can come with conditions, and regular servicing may be one of them. Each brand sets its own terms and we’re happy to go through them with you. Our service record shows the work was done. We are often asked to deal with F-gas leak checks falling due and humming, rattling or squealing from the system, on multi-split systems, ceiling cassettes and wall-mounted split systems.
Systems in Northfields often run in both summer and winter, so a yearly service keeps them efficient. In London, outdoor coils collect dust, grime and leaves, which a service clears.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

What you can do yourself, and what needs us
Owner care supports servicing; it doesn’t replace it. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
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. Opening up the units, the electrics and the refrigerant circuit are a job for us.
How it works
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. So on the day, you don’t need a separate electrician for the electrical side. The work takes an hour or so for a single wall-mounted unit, longer for a multi-split system. For a job in Northfields, tell us about parking, permits and access to the building when you get in touch.
- A date is fixed and the service price confirmed in advance.
- We switch the system on and check it in operation.
- Filters, coils, fans and drains are cleaned and cleared.
- The electrics, controls and refrigerant performance are checked, with a leak check where required.
- We run the system again and leave you a service record.
Preparing for the visit
- Tell us about parking and loading
- Dig out any previous service or F-Gas records
- Let us know if the building has a permit or sign-in process

Advice
Northfields: your questions answered
Can you do air conditioning servicing in Northfields?
Yes. We work across London and the South East from our base in East Grinstead, and Northfields is part of that. Tell us a little about the job and we’ll take it from there.
How often should air conditioning in Northfields be serviced?
Once a year suits most home systems. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
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.
Do you work on all makes?
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 explain why.
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
Common problems we fix in Northfields
Each indoor unit makes water when it cools, and that water needs a clear route out. Sludge and debris can block the tray, the pipe or the pump, and the water then has nowhere to go but out of the unit.
These are the situations we see most often:
- Frost or ice on the refrigerant pipes
- A musty or damp smell when the unit starts
- Error codes or flashing lights on the indoor unit
Schools such as Mount Carmel Catholic Primary School can book servicing for half term or the summer break, when rooms are empty.
What to look for in a quote
- Who does the electrical work, and whether they can certify it
- Which VAT rate the quote uses, and why
- What paperwork you will receive afterwards
Servicing in Northfields: local notes
Draw a one-mile circle round the middle of Northfields and it takes in 6 conservation areas. On the National Heritage List, around 13 entries fall within 0.5 miles of the middle of Northfields; Boston Manor House (grade I) is one. That only matters for replacements, where a new outdoor unit on a protected building can need consent. VOA council tax data put about 63% of homes across Northfields and its surrounding area before 1919, and about 36% of households live in terraced houses, according to the last census (2021). In a terrace, the route to the back garden decides how the visit is planned. In London, a yearly clean of the outdoor coil makes a real difference to how well a system cools.
If you run premises near Brentford station, ask about servicing several units in one visit.

“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.”
