Owner checks or an engineer?
On air conditioning, the filters in the indoor unit are typically 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.
Owners can handle the everyday basics: 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.
About our air conditioning servicing in Twickenham
Whether a leak check is required depends on how much refrigerant the system holds and which refrigerant it is. GOV.UK sets the frequency by the system’s tonnes of CO2 equivalent (tCO2e): at least every 12 months from 5 to under 50 tCO2e, and every 6 months from 50 to under 500 tCO2e. We tell you which band your system falls into and carry out the checks it needs. Typical jobs include a musty or damp smell when the unit starts and condensate leaking into the room, on ceiling cassettes, ducted systems and VRF systems.
In a London area like Twickenham, many systems run hard in summer and for heating in winter, so a yearly service keeps them efficient. In London, outdoor coils collect dust, grime and leaves, which a service clears.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

What we do, step by step
Our engineers arrive at the time agreed with you and run through the plan before anything else. Floors and furniture near the work are covered with dust sheets, and anything electrical is made safe before work starts. The work itself takes an hour or so for a single wall-mounted unit, longer for a multi-split system. If a freeholder or agent needs to agree the work in Twickenham, we can send them the details.
- When you book, we ask what make it is, how many rooms it serves and whether anything seems wrong.
- On arrival, a quick performance check shows how well it’s working before the clean.
- Dust and grime come off the filters and coils, and the drain is flushed so water runs away properly.
- Electrical connections, controls and refrigerant performance are checked, with an F-gas leak check where the system requires one.
- Before leaving, the engineer writes up the visit and talks you through anything worth knowing.
Getting ready for the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Let us know if the building has a permit or sign-in process
- Let us know where we can park and unload
How to get a quote
Published ranges are a starting point; the quote is built on your property, because every property is different. Once we have looked at the job, from pictures or on a survey, you get a fixed price. To get going, ring us on 07833 053749 or use the quote form.
Advice
Looking after it afterwards
Systems last better with the right care. We suggest:
- Check the condensate pipe outside isn’t blocked or crushed
- Keep doors and windows closed while the system is cooling
- File each service record with the manufacturer’s documents
When we finish, we leave a record of the visit, listing the work, the checks and any recommendations. Keep it with the manufacturer’s paperwork so the service history is in one place.
Act on the early signs. A new noise, a faint smell or a drip is easier to deal with early than once the system has stopped.
Honest limits
In fairness, there are a few things this work won’t fix:
- Rooms that gain heat faster than any unit could cope with
- A unit that was undersized when it was chosen
- Poor original installation, such as drains without a proper fall
If in doubt, give us a ring on 07833 053749 or drop us a line and we’ll say what we think before booking.

Servicing in Twickenham: local notes
The Hamilton Road Conservation Area lies close to the centre of Twickenham, within about a third of a mile. 14 conservation areas lie within a mile of central Twickenham. Listed buildings are part of the picture here: about 22 within half a mile of the centre, such as Church of All Hallows (grade I). Swapping an outdoor unit on a listed building or in a conservation area may need consent, so we’ll flag it if a replacement is needed. VOA council tax data put about 39% of homes in the Twickenham area before 1919. If the outdoor unit is high up or behind a locked gate, mention it when you book. London outdoor units collect city dust and grime, so the outdoor coil gets particular attention on a service.
Offices and shops near Twickenham station can have their systems serviced without closing. Site managers at schools like St Richard Reynolds Catholic Primary School can have the site’s units serviced during a holiday.
